I plan to buy one of these packages from http://www.mtx.com/d/t13,1,14,9Cu1v10s0z2/Car-Audio-Complete-Systems-Enclosed-Subwoofer-Add-On-Kits.htm and wanted to know what the best one was? I know the amp will probably be bad so if you could also help me find one that one fit with this subs thatd be cool!
