OK, so the kids have been bugging me for tunes while they surf. I run a shoestring operation here so just trying to set up something basic that makes noise. I picked up a couple Pyle tower speakers and and a 2 channel amp and a second battery. Just trying to figure out how to set it up. Do/can I run positive and ground direct from the battery? I wired it up on the floor just to check before I started drilling and I have the power antenna lead from the head unit going to Remote On on the amp. RCA cables from head unit to amp. Speakers wired from amp. When I power on the head unit, the amp lights flash, but nothing. Any idea what I'm doing wrong? Thanks.
