I got a 2002 IS300 and am going to customize the trunk and drop in a 12" JL W7. I'm looking to buy a Precision Power Class D 1000/1 Amp. Are Precision Power Amps any good? Will this be enough to utilize the full power of the W7?
try the alpine pdx-1.1000. it's fairly cheap and very compact.
those sundown amps that Stylion mentioned are beasts and produce tons of power. the only downside i've heard is that they require a lot of current. if your electrical system can handle it then it's well worth the money as far as sub amps go.
