[QUOTE="RobGMN, post: 8882883, member: 683408"] Unless those have a hidden resistance circuit (or your sub amp has high-level inputs), not the way to go. You'd want an LOC. That said, troubleshooting in the process of elimination. There are a limited number of things that can be wrong. Keep it simple. Verify power at amp, and that the amp is powered up. Do you have a phone (or DAP, radio, computer, even walkman) that has a 1/8" headphone jack? If so, now get a 1/8"-to-RCA cable. Connect it to your player and to the amp. Set your amp gains to 75%. Play some tunes and [U]slowly[/U] turn up the volume. If you get sound, the amp is likely OK. Now, you check wiring. Do a visual, but also swap in other cables. Then you check all the settings on your head unit. Report back here and people will offer more help. [/QUOTE]
