V6Dreamer is correct. If your alternator can't handle 2-3 amps and 2 subs..then you'd have to upgrade that. costing you maybe another 4k+. If you want great bass, 1 sub is good enough. In the future, if you want to upgrade, you can just upgrade 1 sub, instead of 2.

Yep! I still have a backseat. Sometimes when I ride alone, I flip down the backseat to get more "loudness". It just occupies my trunk.

Flashband i think..is what Jojan is referring to. Some like it, some don't like it. It really depends. But, when it comes to deadening, you should see it as an investment, if you're going to do it, do it right.
