To answer a couple of questions. I will be using this amp to run the doors. so do you think I will need a cap?
I've used Ubid twice now and found some great deals. If you look, most of the stuff is sold from ubid, this is good considering that your warranties will be honored, some of the stuff is from their "preferred partners" and some of the stuff is from third parties I believe.
I agree the shipping is a little high, my amp cost 35 bucks to send ground. but that put me at $223 shipped to my door. The cheapest that I found that amp online was like $450.
