I'm trying to install this in the car, I already have the car wired for the amp, and the headunit is ready. The problem is, the guitar amp is already prewired with the amp set to certain levels for the speaker. I can set it to play just bass, but I was trying to figure out the best way to hook it up so it can recieve the feed from the headunit. The second problem is plugging it in, I really dont want to run an inverter to the trunk, but that may be what I'll do. I just thought this would be fun......drive wherever having it pump out sound from the stereo, then you could stop and plug in the guitar. *Shrug* Havent decided if this will work, hopefully I'll get some advice either way. TIA.
