Default Sub advice

Well, I' m about to order a sub/enclosure for my car. Stereo **** is kinda greek to me. Do I want the 4 Ohm or the 2 Ohm sub? Doesn' t the 2 Ohm have the ability to accept more power? What about the sound quality? Which is better?

Impedance, when it comes to subs, doesn't really make any difference except allowing different wiring setups. Specific impedances and VC setups allow more flexible wiring (for example, one sub might allow you to use either a 2 ohm or 4 ohm amp, making shopping for an amp easier).

Sound quality, per impedance, is also negligible in car audio. Higher impedance drivers typically have better SQ (which is why a lot of home drivers are 8 ohm), but in a car environment - and even in a home theater setup - most people would never be anle to tell the difference.

Consider the amp also...and the other (if any) that you plan on powering with the amp... (e.x. if you plan on powering any other speakers with a 4ch amp (2ch for the sub), then, make sure that the impedances work out to get the most for your money. As long as your amp and sub match though and you get the quality you want, good. Also realize that a lot of the subs are DVC (dual voice coils)... 4 Ohm DVC subs can be wired commonly as 2 or 8 Ohms... so make sure that this works best with your sub, and that if you get it is stable down to whatever Ohms you wish.

This is the speaker my set-up will be using:
http://www.edesignaudio.com/edv2/pro...products_id=34
I found a dealer that sells this sub with a box for $262. I plan to set up an amp specifically for the sub, and a seperate amp for the highs. Like I said, I know jack **** about the science of stereo systems. All I know is the stock Monsoon system is complete !!

What did you have in mind as far as amps?

-also you said you were thinking about a separate amp for the other spks? I wasn't aware you were replacing everything, and just not the sub.

-dealer price seems a little high also....that sub ideally needs only a .5cF box - what size is the dealers? You can buy a box that size for under $30 at most places, from ED for about $50, or build your own...

As far as amps, I' m open to suggestions. I have a 240W (for my highs) and a 400W (that I can use for my sub). I have both of those from another set-up. This is the setup I' m looking at:


The box itself is $112. With the $175 ED sub, it' s $262. I have to have the stealth design, because I refuse to forfeit my topless driving experience for music, even though I love my music! Here' s the site with the stealth box: http://subthump.com/acamarostealth.htm

No real need to. eD subs aren't designed to really necessitate large enclosures.

In response to your dual 2 ohm or 4 ohm question, what amp do you plan to use?

It it is known to deliver good power and be stable at 4 ohm mono, then you would get the dual 2 ohm sub. You wire the voice coils in series (I can explain that if you want) and the amp will see the 4 ohm load you want it to see.

If you want amp ideas, the Rockford T3002 is quite cheap and puts out serious power as it's very under rated. Like 800w if you can keep the voltage up. At like 13.4V or so it's power is closer to 400-600. Being a class A/B it will have more impact than those cheap class D amps as well. Something to think about.

BTW, this amp will makes it's most power at 2 ohm mono. So in this case you would get a dual 4 ohm sub. You would wire the voice coils in parallel to create the 2 ohm load.

So you see, it depends a lot on the amp you want to use.

What model do you have?

I'm thinking of putting one T5002 on each of my 2 subs for about 900w each. I'm curious about how loud the fan is and how you like it overall.

A little off topic, sorry.

i got the dual p2 fosgate subs that came with fitted ported box and the 500x2 fosgate amp maybe a little underpowered for the subs, but no negative results hit hard! makes the truck rattle, not like its a good thing but whatever. the fan tho makes a little noise not something noticeble. your subs tho are those 900w peak or rms for each one?

I was saying 900w continous from the amp.
My subs are 700w RMS and 4000w peak so they can handle anything.
Subs

What 500x2 amp is it? The T5002 or another one. I don't see a 500w x 2 amp.

What's swishahouse? Some kind of music, I guess.

Yeah, it will be twin sealed enclosures so I want some big power for them. Think 900 each is enough? I could go 1200w each, but the price jumps up quite a lot for that little extra power.

I don' t really know what amp I want to use. There is way too much technical **** for me to comprehend here. I' m not looking to compete in any sound competitions, but I do want the most out of my musical listening experience. As of right now, I just know that I want the stealth box with the Elemental Design subs, and I want to change out the stock 6½" subs for the Elemental Design ones, and power everything. I really don' t know what the **** I' m doing.
