I bought a 400w Profile California amp about 10 years ago to power 2 10" Pioneer subs I had at the time. It has been used in my car every year since I bought it, and it's now in my mustang powering 2 8" JL's. It has worked perfectly for 10 years and still going.
If you're looking for a cheap deal just to get you going, you could look at a reconditioned amp. I got one from Profile--although I have yet to install it--. It's 4ch amp and it cost me 45 bucks or so. I bought it directly from Profile and they have a 1 year warranty on them. I think most amps these days carry around a 1 year warranty anyway. I think the amp I got 10 years ago only had a 1 or 2 year warranty. Anyway, just another option if you're tight on money and need to get a descent amp to get you going. I have never had any problems with profile stuff.
