Well hello im matthew and im new too this forum and not new to car audio. First of all im working on getting a car then il work on either a 15 inch subwoofer or an 18 or just cheap 3 or 4 15's if i feel crazy enough. i currently own a 9500 mtx 15 inch subwoofer super loud very violent but thats only off a simple 4 channel amp that is a classic puts out power and its all power from four power supplys. Also trying to get a monoblock or class D amplifier to power my mtx for temp till i get something better and im looking at buying one or two Incriminator or fi or DC subs cant make up my mind and its very difficult!
