Hey guys!! I just joined the site but have been using it for research for the past week. I have a 2008 Trailblazer with the non-Bose system.I am replacing the entire sound system. I am starting with a Pioneer AVH-P1400DVD head unit, Pioneer P920XM satellite digital tuner,Polk Audio DB-6501 set up front, Polk Audio DB-651 for the rear doors and 2 Fosgate 12" p3's in the back. I have three amps laying around and this is where I need a little help. I have a Fosgate Punch P205.2 amp rated at 60w x 2 at 4 ohms and 125w x 2 at 2 ohms. I am going to use it for my Polk speakers. I am assuming that it will using the 60 x 2 at 4 ohms. Now here comes the question. I have a Diamond Audio D3-600.1 which is 450watts rms at 2 ohms and 600 watts rms at 1 ohm. I bought the p3's and Diamond Audio amp as a set and the guy said he already had everything setup to run at 1 ohm stable. The other amp that I have is a Cerwin vega Stroker S1000.1. Rated at RMS Power Rating:4 ohms: 400 watts x 1 chan.2 ohms: 750 watts x 1 chan.1 ohm: 1000 watts x 1 chan. I have a set of Kicker CVR 12's in my Jeep compass and I figured that I would use whatever amp that I do not use in my trailblazer in it.

Is the question what amp to use or what configuration to wire it?

Which amp should I use? It looks like the Diamond Audio amp is a little underpowered for the P3's. I am thinking that the Cerwin Vega would be better but wanted to get a second opinion.

Do you plan to run all 4 Polks with the 2-channel amp? If yes, you will be running a 2ohm load to each channel.

Are you going to run the fronts / rears as your 2 channels, or left / right?

I, personally, would use a 4-channel amp. That will allow you to fade front / back and keep the right / left music where it should be - on the right and left.

Your question was relating to the sub amp I believe. If both amps can run a 1ohm load, I would use the better amp. Diamond Audio vs Cerwin Vega. Humm. I don't think either is CEA2006 compliant, so their published numbers don't mean jack, really. I would temporarily mount each of them and see which one you like better.

Actually the Cerwin Vega amps are CEA2006 compliant. However the Diamond Audio amps are not. I am actually purchasing a 4 channel Cerwin Vega amp to the power the Polk Audio speakers. I am also getting ready to do the big 3 and upgrade the battery and possibly the alternator.
