I have a basic MTX thunder series (2- 12's) and RF punch 350 amp. I like it but i really rather have 10's. There ae so many cheap stuff out there. I bought a 2- 12 RF sub for $50

. Then I used this U.S. Acoustic 2 channel 1000 watt amp (paid $100) mated with a 4 channel (old and cheap ass) JVC head and it f'n kicks like crazy!
But dont listen to me, I dont know much about car stereo stuff. I can wire it up and install it, but I really have no clue on what is good out there...
