Hi guys I am new to CCA and I am looking for some friendly advice and some opinions from the more experienced audiophiles. I am slowly putting a system into my 1996 Chevy Silverado Ext. cab.
This is what I have so far for gear:
HU: Kenwood MP-345U > installed
Door panel: JBL GTO628 6.5" > installed
Rear pillars: JL Audio C2-400x 4"> not installed (still stock)
Subs x2: RE Audio REX10D4 10" not installed

I will be installing my subs into a duel 10" custom enclosure made to fit under my rear seat with 1.7cuft. and filled with poly-fill.

amp for door's & pillars: Kicker KX300.4 not installed

Amp for subs ????? I have a few in mind but i would like a few opinions of what i have listed below? keeping in mind I am on a very limited budget looking for under $200.

1: Orion Cobalt CO500.1 (CO5001) @ $114.99

I ran and older p300 back when I first got into this stuff. It did the job.

those newer RE amps are supposed to be very good for the money, supposedly they will do close to rated in real world and for the price, its worth it imo.
as for the rest of your setup, it looks liek your on your way.

Since u say u new into this from my own f%&k ups in the past and thinking everybody gave out right answers .... make sure the power u want from the amp u pick is at the right final load.. Nothing like ure first setup being a ZX 1500.1 that u can only use half of lolol

loketar

thanks alot guys
@>AyZe : I am not sure what u are saying here? If I match up the subs(RE Audio REX10D4 10" x2) with the Amp: (RE Audio DTS-800.1) Is this a good match and will i get all the power from the amp? How is the best way to wire this up?
thanks again..

Positives to positives negatives to negatives will give you a 1ohm load which is fairly ideal.

AyZe

exactly, "said" amp does 1000rms @ 4 ohm - 2000 rms @ 2 ohm - 4000 @ 1 ohm etc etc not all amps can be wired down to 1 ohm. thus u have to go back up to 4 ohm(dual 4ohm i assume from the "D4") and u get 1/4 the power u assumed wen u bought the piece.And if u were like me and trusted the guys at the shop u bought from u learn alittle and say wat in teh fck!

but u want to find the power u want @ 1ohm(is ideal) or 4 ohm.
So if any of the amps in your list cant be wired down to 1 ohm i wouldnt even consider them.
i might not be explaining this clearly i apologize but i just got up lol.
HAS ABOSOLUTLY NOTHING TO DO WITH BRANDs.

off to work now

loketar

ok, I think i am following you so far. And yes they are DVC 4 ohm. So I have 2 amps I am really thinking about here. I will include the specs for the subs(that came today, wohoo!!!) and the amps (I have not ordered yet). PLease advise as to which one matches up the best and will give me the most power to both subs....
thanks in advance.
Cheers, Loke

Both amps will do just fine and will be very close in power when wired to your subs (MTX you'll have to run at 4ohm).
I'll throw another option out to you; you can also look at some class A/B 2ch amps as there'll be lots of choices for ones that make ~400rms bridged at 4ohms.
You're going to find that many low-power sub amps are going to do max power at 2ohm (not where you want it). This will make a bridged class A/B amp a great fit (especially since at 400rms efficiency isn't going to be a concern).
