Amplifier question
calvynandhobbs:
I went out and played with the amp at lunchtime. At 0 gain the protection light goes off and the power light comes on. I started to turn the gain up and it trips over the protection mode at less than 1/4 turn. Should I try disconnecting speaker wires to see if the gain will go up higher indicating that the wires are grounded out? I looked at them and didn't see anything that was questionable. Could it be that running the sub off the rear speaker wire is causing the trouble and I need to upgrade to a radio with RCA outputs? I'm really new to radio stuff. This is the first time I've had anything more than just a stock radio and speakers. I've never had an amp in a vehicle before.

is the sub the only speaker running off of the amp?

Yes, it is

I'm not sure if they still sell them, but a few years ago when not every stereo had RCA jacks, you could buy an adaptor that had 4 speaker wire inputs, and 2 RCA outputs through a box. From what I remeber the box dropped the level of the outputs. I would think a stereo shop like Great Scott in Norwich would carry them, mabey even Best Buys.

I think I would just buy a new radio with RCA jacks before buying a box and trying to figure out where to mount something else.
