Here is an 03 H2 that my installer did over the weekend. He ran 2 JL 1000/1 mono blocks powering 2 12W7's, a JL 450/4 for his 2 sets of 6.5 inch MB Quart components. An indash DVD player, a rear seat DVD player for the 2 front headrest TV's, A Sony PS2, 5 total TV's with two more being added soon, 5.1 Dolby Digital surround sound. A camera on the back hitch that displays what is behind the H2 as it is being backed out. An extra battery. And 2 270amp alternators are being paralelled together in the near future. This thing was crazy it pounded so hard. The wiper on the back window would bounce about two inches off the back glass everytime the bass would hit. All for doors and rear panels would flex out from the bass.
