New stereo components for my 94 RT/TT

KnuKonceptz is over sized for a reason, they do not use pure copper. I would still use it if it was not for the great packaged deal I got on stinger product from Darvex.com.

I am sure that his 4GA wire would be fine, at least try and measure the voltage for loss.

I have a 6ch amp bridged x 3 2 for the fronts 1 for a sub. 215w /ch on the fronts the sub ch is about 315w . I've gained more than .65v just switching wire that's the point. Now I'm at just under a .25v loss. As you know with an amp having an un regulated power supply that matters.

Indeed, what 6channel are you using?

I'm just starting to look into Rockford's boosted rail amps ( PBR300X4) So far the 1.53" x 4.25" x 6.75" footprint, good amount of power, and the price ($170 from an authorized dealer) have me intrigued. Small amps with over 40w per channel are hard to find...especially for a decent price.

I'm going to continue researching the PBR300X4 but right now I'm thinking about going with this, use my RF 451S for the sub, and buy the new RF P3SD2 12" shallow mount sub. All of this will easily mount into the floor.

Just looked at the boosted rail vids interesting... It's efficient that's for sure. The biggest wire that fit the input is 10G. I'd want to compare it's sound output to an ab amp though before the install was finalized.

I'm on my way to completion; just waiting for carpet to arrive. I still need to build the top carpeted panels, a little carpeted wall behind the rear seat with fans in it, and tidy up some wiring.

I went with the RF PBR300X4 amplifier. It sounds every bit as good as the old Phoenix Gold amp. The PBR300X4 is advertised at 75w per channel @ 4 ohms at 14.4v. The birth sheet for my specific PBR300X4 is rated at 89w per channel.

Everything bolts to the floor using the factory mounting locations.

Final Equipment list:
Head Unit: Pioneer DEH-80PRS

Rear Speakers: Infinity Kappa 693.5i
Subwoofer: Rockford Fosgate P3SD2-12
Speaker Amp: Rockford Fosgate PBR300X4
Subwoofer Amp: Rockford Fosgate 451S

I would be concerned with the depth of your box... You don't have enough cubic feet for that subwoofer, I guarantee you will have stunted bass..

[Omega-Tron]

I wouldn't...it's right in spec.

I have about .98 to .99 cubic feet of air space after accounting for the subwoofer displacement. This subwoofer is rated for a 0.6 to 1.2 cubic feet sealed box with 1 cubic feet recommended.

Just to clear something up. KnuKonceptz KCA line its copper clad aluminum their Kolossus line its Oxygen free copper.

I think he meant for the space between the bottom of the sub and the box its self. Its has a pole vent on it for a reason, restrict that and sub wont last much. I would say you need 1" gap between them.
