Not going into an LS car, but an LS truck.

I'm about to order up a Rockford T5001BDCP for the audio system I've been installing in my 2009 Avalanche. All the wiring and support is in and I'm stumped on what subs to go for. Whatever I get I'm probably going to put 200-300 RMS to each at 2ohms I'm hoping. Gotta see what the amp is rated at when it comes in to decide the impedence.

Here's what I'm working with so far. Deck is a JVC KWAVX840, truck is completely sound deadened with Raammat and closed cell foam. Gonna tune it up with a DD-1.

In the sealed box I have .72 cubes per side and 5" of mounting depth. The holes are drilled for 10"s and I listen to rock and heavy metal. This is a quality box guys, rhinolined, bolted in and heavy.

I've considered and bounced back and forth between the following.

-New 2012 Rockford P3 shallows. These don't seem to go lower than 40Hz and I've heard there are better subs for the money. Don't want a "shallow" if I don't need one. Looks like they lack Xmax

-JL 10W1V2's. These look good. Heard lots of good things about JL. Lower than 40 HZ. It's semi "shallow" but not a typical compressed sub. There's no pole vent so it should work fine.

-Polk MM1040's. These look good too and also not a super "shallow" sup. Lower than 40Hz also. Seems to have more excursion than the others and handles more power. Nothing but good reviews on these.

This is my first time doing something like this guys. Never installed anything worth a damn in the TA. Too heavy, but now I got something I can get something decent into, I've sort of run into a roadblock and can't seem to make a decision.

For that small a box I'd go with a Dayton HO.

JL all the way. They are at the top of their game. Hertz also make awesome subs, it they're real pricey. That said, I prefer the JL W0v3 to the w1, way better SQ and similar output.

That amp is really expensive for 500w x1 @2. Id get a PDX m6 for the same price and extra 100 watts of cleaner power. Alpine amps are built very well and are tiny especially compared to that RF. or even just get an MRX-M55 for less money and still more power than the RF.

Any reason why? Have you heard them all? I'm really leaning towards those Polks. Those things look like they really move.

I'm pretty much set on the Rockford Amps. They have some features and a look that I really like. I'm sure the Rockford Power is going to come rated close to 600 if not over. I'm more interested in someone helping me select the subs. Besides that WO is too deep for me to fit. I can't go deeper than 4.5".

I guess this was the wrong place to ask. I would need close to 7" of depth. I guess you guys aren't too familiar with fitting subs in a truck.

I just found the Sundown Audio SD-2 series. These look they'll take a shit all over everything I've looked at so far! Why did no one mention these to me?

They're throwing over a 1000 to one 10" and can't blow it.

http://www.youtube.com/watch?feature=player_embedded&v=pK_rVrm81D8

Looks like I'm going to have to go more than a T500, more like a T1000, they're rated at 500RMS each.

You guys think they'll shake the truck down good?

Are you looking for SQ or SPL? X max isn't everything. One of the best SQ subs around is the thin JL 13tw5. They sound a lot like a w6 and take the same power. Your box specs are right on the money and they're 2.5" deep. I recently did a Jeep SRT 392 with a pair of the 13tw5's each on an Alpine MRX-m12 and it bumped so tight and clean and hit hard.

Box specs are not even close. The box already has two 9 inch holes in it and dual chambers. How could I possibly fit a JL 13?

Nah, can't really cut a bigger hole either. I'm not willing to fork out scratch for one of those JL's let alone two. Besides there's some decorative trim around the holes. Couldn't do it without hacking the box up.

To be honest this is my first time really doing something like this. Space and money are obstacles obviously. I'm not really sure what I want really. I honestly have no idea what it's going to be like in the truck once I get it all finished. It's difficult to demo anything. Not many shallow mounts around here and they're in generic boxes, gains probably aren't set right. And I haven't had a chance to really listen to anyone with a decent stereo in their car.

From what I hear shallow subs are generally pretty lackluster. I'm going for the most SQ and pound I can get out of space I have available with the box I have.

Most sq and "pound" possible doesn't go well with budget oriented. Those JL thin subs sounds as good as a w6 which is arguably the most popular SQ sub around. Since the cone is 13.5" they will hit really low and hard. Sundown subs aren't the best on SQ, they make some good stuff like the new sa-8 is pretty nice but that's the only one I likeOAS much as a JL or Hertz. Look into some hertz energy 10s that would be a great option as well for a lot less cash. They won't hit as hard as th tw5s but they have awesome SQ.

Your box would most definetly work with the 13s, I've done it in the escalade version of your truck.

Google "Dayton HO," I'm a member at two different Audio forums and this Sub is highly recommended at both sites. The Sundown is a great Sub and so are the JL's but with your airspace (remember that you have to subtract the air space that the sub takes up from the total air space) id go with something different. I've only heard one so far and I was amazed, I'm now planing to do a single 10" in a ported enclosure for my SS.

I've read that those DS-2's reminded others of the old JL W6. I've also read some of the reviews on that 13.5 and others said they had some pretty slow response. For the price I read some pretty piss poor reviews. I don't understand a different between SPL and SQ and how subs can be designed for one or the other. The purpose of either or is to duplicate the original recording right? This is a sealed box and not ported, it's not geared towards massive SPL groundpounder, my build never was. But I definitely want some headroom, want to feel it, have a quality sound, maybe impress a couple along the way, and to have more than I will actually use. Maybe I would be perfectly happy with some shallow Pioneers, I don't know, like I said, never done this before.

I guess everything that I'm asking is subjective and I'm just going to have to make a choice based on what I've found so far. But whatever I use it's going to have to be a 10" speaker that requires a mounting depth of 5". I'm not going to modify the box in any way. I've heard some "mainstream" 10's before and it sounded plenty to me.

Seems like not many people are familiar with Sundown. This SD-2 is a fairly new release and as of now I've heard nothing bad about them. Even after an installation in my .7 chambers I still have over the minimum requirement which is .5. Sub displacement is only .08. Qts. rating is also in the range ideal for a sealed box. It's a little bit more than I expected and as far as I know is the deepest sub I could possibly fit in the box I have. That SD-2 just looks badass. Huge magnet!

A video can only show so much but here's one, he seemed to be pretty happy with them.
http://www.youtube.com/watch?v=rYiu8bwptxU

Sound pretty smoothe here too.
http://www.youtube.com/watch?v=-0-EtFHVrvA&feature=endscreen&NR=1

And another with which seem to have a better mic. Looks like an SQ oriented setup.

http://www.youtube.com/watch?v=VekISSXSPVs&list=FLojPMxoZ8hcoXSU_TsQcGRQ&index=1&feature=plpp_video

And the videos of them guys trying to blow 'em up and failing. Looks like some stout woofers to me. I was pretty much sold on that. People blow JL's all the time.

I've also looked at the dayton HO's. The only one I could run is their shallow requiring only 3.1 inches. That DS-2 is over 1.5 inches deeper.

Can anyone give me a reason NOT to go with these DS-2 subwoofers off 1000 watts?

No ones trying to give you a reason not to go for the sundown, its just sundown isnt know for SQ. To say its hard to blow a sundown is fine but to say its easy to blow a JL is wrong. Its easy to blow any speaker if you dont know what your doing. If you just throw a sub in a prefab on a cheap amp without enough power and the gain up to much it will get blown. People kill speakers not amps. Whatever reviews youve read giving the tw5 a bad review is simply not true, ive never read a bad review and love those subs even compaired to my 10w7s they are nice subs. What does slow response mean? Ive never heard a speaker described as slow. If you end up getting a rockford amp make sure you dynamat it, the power they make is legit but they rattle like hell.

Doesn't matter how good that jl is or isn't, I simply am not willing to buy or go through the pita to fit it. Tell me what sundown is known for? My truck is completely sound deadened, but what does that have to do with Rockford amps?

I got a response from that guy on YouTube with the sq setup I posted above. He Said the sundowns will easily outperform the other subs I've mentioned above.

Thanks guys but that is the route i think I'm going. If anyone is interested in what I find let me know.

Im not trying to push you toward the JL, but others may read this thread in the future and i dont want them to have bad info on the sub or brand. The case of the amp it self will rattle, the "t" amps all do. Put a peice of deadener on bottom of the amp itself. You said you like how the Rockford amps look, that's not a reason to buy an amp. They make good power, but are expensive and large. I'd seriously consider the new Alpine MRX-M120 it's a killer amp for the money. It's all you need in a bass amp, even the most SQ concerned will run Alpine X power amps on bass because they are known as a great value. 1200w for $399 retail, never pay retail on car audio.

If never heard anything about Rockford's rattling. That's new's to me. Funny how you say you're not trying to push me toward's JL but try to steer me away from Rockford's in the next sentence. Maybe that's bad info on the brand?

I hear you and I'm not trying to trash JL, if that's what you like then good. I was close to deciding on a W1, really doesn't look like a bad sub, but I haven't heard many so I really can't say. And I hear you on paying retail. Store retail is even worse. A T1000 can be had for 379 shipped, and those Power series are monsters though, way underrated. Maybe that's why they're big and expensive? That t1000 will probably come rated at closer to 1500 RMS @ 1 ohm,. I could probably up it 4 ohms, still run the subs up to 500 RMS, and the amp not even sweat. It's not just the physical look, but there's some really cool class BD, interference resistance, and constant power technology. The amps are really efficient AND 1 ohm stable if I choose to drop it later on. I've already ran the bass boost knob for a Rockford also and done some other things with the sizing in mind for 'em.

Besides, if you know who Steve Meade is, he's all about Rockford, and I'm a big fan of some of his stuff, and his crazy builds are awesome. I already have some Rockford coaxials in the doors and really like how they sound. Quality stuff to my ears.

That's 1st hand expirence with the rockford amps, never really noticed it until i heard it on soundman. But i added deadener to the back of one that was in the shop and it was a noticeable difference.

After the wx, the w1 is my least favorite JL, i actually like hertz/audison stuff over a JL but its expensive and hard to find. Jl really isnt that expensive if you go to the right dealer, its not price protected any more. Those tw5s can be had for about $400. But the sundowns will be nice. You would have had more SW options for 8's.

I used an SMD DD-1, its a great device. Steve mead is an SPL guy I like SQ. He does seem to know his stuff tho.

I actually have a DD-1, haven't gotten the opportunity to use it though. I might have considered the JL, but that W1 is the only one I could have fit in this box. Have you seen those Sundown SA-8's? Stout looking 8 for sure.

I did a quick search for Rockford and buzzing and found one other bit of info. It was on one of the older t1000's.

Did you hear that on one of the newer ones? There aren't any fans or any other moving parts that I know of in the latest power series. I've listened to Rockfords in the store and didn't hear any noise coming from them.

By the way, what kind of Db do you guys think I'll get from these 10's in that box with 1000 RMS total. Any flexing, is it going to rattle the mirrors and change in the console? Anything I'm going to physically feel and see?

I really don't think I've heard anything like this before.

V8ImpSS
05-14-2012, 05:12 PM
Mirrors yes will vibrate, change in the console won't, your not going to be bending windows or anything. Hard to predict but I'd saw low 130s tops. Get a 1500 or 2000 watt amp. If guys are pushing 1000 to a single sundown then your good to do the same. More power will get better SQ as well as more SPL. Amps are all about distortion, they produce their rated power at a certain amount of distortion using the CEA-2006 standards. So if you had 2 amps pushing the same driver to the same output, an amp with more power will be able to do so at a lower rate of distortion. Distortion is what kills speakers, that's why with a more powerful amp drivers will be louder. So if your wanting a lot of bass and LAN on cranking it a lot I'd go for a bigger amp. The MRX-M240 is my favorite for big power, it will be out soon and I used to use the MRP-m2000 (old version) all of the time. All amps are "underrated" to guarantee the customer gets what they paid for. That's why that doesn't give the RF amp an edge as far as power, if its a good brand they're all like that. So that new m240 will be around 2500w @2 ohms for $699 retail. I used to sell the MRP-m2000 for around $450 to give you an idea. Like I said twice that's 1st hand expirence with those rockfords, whether you believe me or not is on you. It's not moving parts, but like anything else in a car with a lot of bass, stuff vibrates, some more than others.
