I can show you what I bought and you can see if you like them.
Zapco rates their 9.0 at 2000 watts, but that's rms and is way under rated. This amp was put on a meter and put out 4,500 watts. Never get's warm and never shuts off. You can run this thing 24/7 at 2000 watts rms and never have a problem. The exterior plate slide out so you can chrome or paint them to match your interior.
The Treo sub is the best I know of. When I bought mine, the warranty didn't give a max power limit like all other subs do. They just say "This sub will handle any amp made" 1 year warranty. Zapco amps and Treo subs have been used to win more world finals than any other brand.
Not sure if this is a little too much for you, but why not get the best if you're going to buy a system. Just my opinion.
