Need Help Choosing an Amp

[Ric2L]

Hey all, I'm new to the forum and pretty much the car audio installation. I currently have a 2005 Chevy single cab P/U truck. So far I have installed a Kenwood KDC X995 head unit (22 watts RMS/50 peak x 4 channels) with 2 Rockford Fosgate Punch P1653 6-1/2" 3-way Full Range Speakers in the doors (RMS=60 watts each/120 watts each peak) and 2 Rockford Fosgate Punch P1462 4" x 6" 2-way Coaxial Speakers in the rear pillars (RMS=35 watts each/70 watts peak). I just picked up a Kicker CVR12 subwoofer (400 watts RMS/800 peak) from a coworker today and now I need to buy an amp. I'm giong to build a sealed box for the sub next week.

So, my question is what would you guys recommend for an amp? Do I go with a single channel amp or maybe a dual channel amp? I'm figuering around 400 watts RMS should be fine. Would you run the speakers off the head unit and the sub off the amp, or everything off the amp?

I really don't need a compition system just need to add some bass to the current setup. It seriously lacks bass. Basically I'm trying to get a good quality sounding system for listening to mostly classic rock & roll music.

Thanks in advance for any help/suggestions

Man..I'd do a 4 ch class A/B amp on the highs and a class D monoblock on the lows. This will give you higher, clean and undistorted volume level overall. If you are not shy about used, there are some real good deals here in the classifieds...look for 60-75w/ch on the 4 ch and 4-500w on the bass amp. I would highly recommend ported for the sub box. Just a 3 or 4" port out the side of the box facing the cab corner would be great.

Examples:

Rockford Fosgate R500-1D 500W RMS PRIME Series Monoblock Amplifier

Rockford Fosgate R300-4 (r3004) 300W Prime Series 4-Channel

find out what coil configuration(dual 2 or 4 ohm, single 4 ohm) before you look for an amp.

 

[Ric2L]

The sub is Dual 2 or 4 ohm config.

look on the back of the sub and see if it says dual 2 ohm or 4. Dual 2 will run at 1 Ohm or 4, and a dual 4 will run at 2ohms or 8- makes a big difference when your looking for an amp.

The sub has "Dual 2 Ohm Voice Coils", this is printed on back of sub.

Or to make it easy just cop a 5 channel lol. There are plenty of 5 channels that have at least 400 rms for a sub.
