I need help finding a site to order an integration harness to wire an amp into my stock cd player. I have a 2000 Chevy Silverado 1500. It has the stock cd player i am going to keep but I need to wire up my amp to it via a harness. Sonicelectronix.com has exactly what i need but is out of stock/backordered. Any other sites where I can get this would be great. Thanks.
