Question Please Help Build A System With What I Have.

I began upgrading my car stereo almost blindly and bought the following components:

Pioneer DEH-P6400 headunit
4 Kenwood KFC-1798ie speakers (2 of which are now blown)
Rockford Fosgate Punch 360a2 (Sitting in closet)

I need 2 new speakers and would like a 10" sub in a stealth encolsure. I need to do this rather cheaply.
Should I buy another set of Kenwoods, or different speakers? Kenwood speakers seem to have terrrible reviews.
Any advice please.



Background for those who care:
I replaced my Monsoon with the headunit and speakers. I made the (i think) mistake of getting a schematic and cutting and splicing wires so that I could run the speakers through the Monsoon amp. I'm pretty sure I sent the signal meant for the hatch to the Kenwoods in the sailpanal and sent that signal to the 4" speakers in the hatch. Now both Kenwoods on the passenger side have blown. One went months ago, one yesterday. I expected the speakers in the hatch to blow almost immediatly, but they lasted over a year and blew last week. I plan to bypass the amplifier entirley now.

I was given the amplifier and know nothing about it, but was hoping to run a single 10" sub with it. My time has been occupied so I never got around to this. Can it run a sub?

OK, that word has as few connotations. I mean I'd like to do this in the most inexpensive way possible, while maintaining a respectible level of sound quality.

I mean, I don't expect to do this only dishing out $50. But I just finished paying off my credit cards, I'd like to stay out of debt for a while

By cheap, I mean I would like to use what I already have and buy respectable, yet "budget" products.

Pioneer Rev coaxs are awesome, so are the Phoenix Gold RSD coaxs. You can find those cheap.
Stealth enclosure you can build yourself for $35.
Sub depends on your musical preference. Not many subs work well in the stealth enclosure though.

As far as subs:
I listen to a variation of music, mostly classic rock, zepplin, dylan, the beatles, also dave matthews, sublime. SOmetimes i still listen to metallica , godsmack. but for the most part im looking for sound quality, not big boomy bass.

Do you mean buiild them out of fiberglass. I might try this over the summer when I get some time.

Are the Kenwood speakers really that bad? I'll look into the speakers you mention.

Thanks

Should I buy another amplifier for the speakers, or will the HU power them enough without the monsoon amp?

Depends on what speakers and how loud you want it. Find speakers first, try them with the stock amp and then make the decision as to whether you want a better amp or not.

How 'bout http://cgi.ebay.com/ADS-A-D-S-246ix-...QQcmdZViewItem ?

I bought Kenwood 3-ways, reading the number on them I thought they were good speakers, but I've heard nothing good. Anyway, two fo them have blown and I don't know if its the amplifiers fault. I figure I should remove it in any case.

The speakers I have are only rated to 50rms, the headunit 50x4 i believe. I figured these would work very well together, but at higher volumes it does sound pretty bad. However I hav not tried to run them off just the HU yet.

Head units are not even 20WRMS. I wouldn't expect more than 10WRMS from most of them. Look for a 75-100WRMS amp, and look for one with a lowpass option. Lowpass your front speakers at about 85Hz. You can go a bit lower if you get enough volume out of them without distortion, down to maybe 75. I wouldn't go lower than that. But the highpass is very important.

If you want, you can go for a 4-channel amp to drive your front and sail panel speakers. Try a Phoenix Gold Octane 8.0:4. Just unplug your monsoon amp and run new speaker wires to the doors, IMO. It's easy to do, there's no plastic connector or anything so you can slide the wires right through.

Forget about the hatch speakers in any case.

Also, never buy 3-way speakers unless it's a component system and you're willing to do the work to mount all 3 speakers. "Triaxial" speakers for the lose.

Thanks for the info and options.

I was under the impression that my HU was a "good" HU becuase tof its output power...[bang]
I might hop on that amplifier. This is already guarenteed to cost me much more money than I expected lol.



So if I move the working Kenwoods to the sailpanal,
buy a 100rmsx4 amp with lowpass,
get a set of components for the front speakers,
and get a sub and make a stealthbox,
I'll have a pretty good sounding system right?

Will my rockford fosgate amp work for a sub?

Now I have to find these in good quality for a great price.

I plan to shop around like crazy trying to find this stuff. What do I have to look out for as far as bad brands, and knowing what not to buy?

I'm not a big fan of older amps usually, but it should work fine...

OK so, if I buy a set of components for the front I'll need a 4channel amplifier for my speakers. The Kenwoods are rated 50wrms, but any set of components will be rated higher. If I buy a amplifier, will I be able to control the amount of power im sending to the components and the kenwoods?

Unless I completely missed the point of something, that should be a HIGHpass amp, not lowpass. Lowpass amps are for subs, not main speakers because they pass (*drumroll*) low frequencies. I think you may have gotten this from Dragonrage's post and I'm guessing he meant to put highpass (mainly because he did say highpass later and it makes more sense). I don't think you could even find a 4 channel low pass amp. Anyway... an inexpensive Class A/B 4 channel amp should work fine for you.

As for your 360.2, I pulled up the manual on that and I think it'll work fine. Just keep in mind that it won't be stable if you bridge it and run 2 ohms. So either get a single voice coil 4 ohm speaker or a dual voice coil 2 Ohm speaker (run the DVCs in series to make them 4 ohms) and you should be good. It looks like it puts out decent power with 360W bridged @ 4 ohms (nothing to write home about, but certainly adequate for a single sub and a tight budget).

Some (most?) 4 channel amps have independent gain controls for front vs. rear. You should be able to dial them in so that they have similar volume as you turn your volume up. Do keep in mind that your lower wattage speakers will be easier to blow, so just listen for distortion and turn the volume down if you hear any. Learn the limits of your system and respect those limits (or just blow them so you have an excuse to buy more speakers).

Disclaimer: I'm no expert by any means, so if someone comes along and says I got it all wrong, there's a good chance they're right.

OK, so after realizing how much 4-channel amps cost, I am reconsidering going that way.

Is it possible to buy a 2-channel amp to run a set of component speakers for the door speakers, and still run 2 kenwoods in the rear seat off the HU?

Would I be better off selling the 2 kenwoods and just runniong off the comps and a stealthboxed amp?
