Well I got to test the amp again yesterday. Unfortunately, I found out that the channel 1 & 3 speaker outputs don't work at all. My wiring was all correct in the first place. My ground was better, I didn't sandpaper/scrape of the paint the first time, so that solved the problem of the speakers sounding like it had no power. I also turned on the engine, no noise.
I contacted the seller, he told me that it was working perfectly fine when Tweeter uninstalled it for him. I told him I tested it in everyway I could and I have checked the settings etc. I asked if I can return it to him, hopefully he will take it back. I personally think something probably happened during the shipment, he didn't pack it well on the sides where the speaker outputs and rca's are. There were no padding there and it was right up against the box.
Is there anything I can do to fix the amp? What would happen if the fuse was burnt? Should I open up the amp and see whats going on in there?
I liked how my speakers sounded when I put channels 2&4 up to the front. It was definately playing clearer and at louder levels. I used to turn the volume knob at 20. Now I could only go up to like 8, and then when i put on the crossovers, I could go up to 10.
So I guess I'm in the market again for a new amp. I might just get a 4 channel amp this time and just power up the fronts and the sub, and run the rears off the headunit. However, would that screw up with the fade and balance settings? What if I were to get an Alpine deck, would that mess up features such as time correction?
