So i went out to bestbuy today and got the gmos-04 wiring harness to hook up a new hu. Then i went and got a brand new kenwood kdc-152 from my work for cheap, only 62 bucks. Well its all hooked up and for one the volume only goes to 35, hardly pushing over my 12" aq in the trunk and is distorted as **** on radio and cd. I didnt solder but i never have befor. So is it the deck, my lack of soldering, or is there a way i can turn up the monsoon amp. With my 6 disc in there it easily could be heard crisp and clear over my sub.
