I had a single 10" explod sub hooked up to a no-name brand 600w amp (acutally 300wX2 bridged into one). I mounted it in a big sealed box approx 18x18x18". In my '91 hatch it sounded great... noone could believe it was only a 10" sub! If you're looking for something that sounds good, gives some thump, but doesn't blow out your ears, it'll do great! If you want to blow out your windows and the guy next to you, you probably will want to either go with 2 12"'s or a different brand. There's my $.02
