lol, talk about opening up a can of worms.
Should have come here before doing all of that.
K, so you bypassed the stock amp via using the other wiring harness already present right? Ok, so now your headunit was sending the power to the speakers right? And now you say the front right doesnt work? You're first step there would to be to double triple check your buttconnectors or whatever was used to connect the HU, after that you should have tested continuity across your components + and -.
After finding that it was probably just a bad connection somewhere in the mix, you would have been able to promptly fix it and enjoy your radio.
Yes, installing an aftermarket amp is a job in itself, you must run a thick enough gauge power and ground wire from your battery and to your frame. You wasted your money on the sony amp HARD. They are junk. Out of ten on a quality of amp scale they are a 2.5 out of 10.
After installing the amp and finding that you bought a 4 channel amp and you are trying to drive 5 speakers, you should.
Take the sony amp back to the store and ask for your money back, walmarts usually cool about returns.
K, now that you have returned the sony amp. When you bypassed the stock amp, how did you do it? By using the alternative plug behind the HU right?
