I am a custom car audio, and mobile video installer at Audio King in St. Paul, MN. I ususally keep up on all the latest gadgets for cars, which is pretty cool I think. I have an Alpine head unit, ran to a BD1000 mono block Rockford power amp. The 1000 pushes three ten inch Rockford HX2 subs, very nicely. The subs are surrounded by a complete custom set up that fills the space of the trunk (which is what trunks are for.......right?) It includes white vinyl rapped around the subs, borderd by red vinyl, and the rest of my entire trunk is bright red crushed velvet to match my car. I also have a punch 400a running my Diamond audio front components w/ flush mount tweets, and pioneer rear speakers for rear fill. I am very pleased with the result of this setup. Monitors are in the near future.
