Installed a 2000 model Alpine HU today and I think I need to up the wattage. Right now I'm looking at 4-channel amps. I'll probably run the DX7 door speakers in a 2-ohm configuration and bridge the second channel for the 10" sub. Also, my HU has only one preamp out but I've been told I can connect a Y-cable to access all 4 inputs of the amp. HP and LP control is also important.
Any suggestions? Kicker, Alpine, MTX? Nothing too high-end please.
