Hey guys i'm new to the forums but i've been reading for a lil' while, anyway the reason for this post is to ask a question that i can't seem to figure out on my own.. let me start by filling you in on a few things.. I have a just started to put together a HT so far i have a JVC D-series 32" -Display Yamaha RX v-620 -Receiver Paradigm Titans - Mains Paradigm CC150 - Center Tannoy C-6 - surrounds My current setup also includes a Cambridge sound-works DTT3500 home theater in a box, just the amp running two 12" alpine single voice coil 4 ohm subs running at 8 ohms from my old car setup. My question is what would i need to run the subs at 2ohms off of the Alpine v12 amp that i used to run them off in the car but this time in the house?? I don't want "TONS" of bass, I just want the bass to hit lower Edit: I know that i need a power supply to go from 120V AC to 12v DC at 20 amps. any idea on where to purchase something like that and how much?
