warren g speakers

i'm afraid forbidden's absolutely correct about your sony amp.....it's probably true that it's rated at 1000 watts....but 75% is heat. What does it say for RMS on this particular sony amp?....

the rms on the sony amp is 400watts . the model number for the amp is g-840 i think and the speakers are cs-wg1200. also i was in best buy and i seen a punch amp that has 1500 watts. i think it is the punch 501s. will this amp really do 1500 watts or will it only do about 500 watts

The Rockford amp will put out 1500 watts RMS x 1 @ 2 ohms. your subs are dual 4 ohms which means you can wire them 2 ways, either 2 ohms or 8 ohms. That Rockford amp would be just about right for what you need. Your subs are rated at 350 wats RMS each. If you wire them in series-parallel you will have a 4 ogm load and can hook it up to the 501S and get 500 watts RMS, 250 to wach sub. It would look something like this:

The 501's ratings are below

I second bberman, not a good match.

 Bfog99, be careful on your advice, while all advice is usually helpful, in this case you have misquoted peak power for rms, while it may have been a simple oversight, it can lead a customer to purchase the wrong thing. The amp has a 50 amp fuse for it which will yield a result of result of approximately 720 watts in bridged mono mode, if the amp is 100% efficient. While the amp may be capable of playing a 2 ohm mono load and delivering close to 1500watts, it was not designed and engineered to operate at a 2 ohm mono load for continuous use, expect to have problems,NOT RECOMMENDED. No offence intended dude, just did not want to see someone set off on the wrong foot.

I was actually recommending a 4 ohm mono load at 500 watts. It would actually be under powering the subs a little, but it would work. I didn't say it was an exact match, but just about right. It would work.
