i have put a total of 12 hours in my car audio install and its still not working right. i am installing a pioneer 1600w max amp with 4 alpine speakers using a scosche 4 channel line output converter so i can keep my stock head unit. I have all of the wires ran and have checked to make sure they are all wired correctly that i know of. i have all 4 speakers hooked up to my LOC then I have 2 sets of RCA's (2 white and 2 red) running to my amp. the white rca's on loc, which i'm assuming is where the problem is coming from are not working and are for both left speakers in my car. All of my speakers work if i move a working rca to each individual input on my amp though even if i use the white wire. I have tried switching out my RCA wires completely as well and it didn't fix the problem. all of my gain adjustments are turned halfway on the LOC and amp. If i change the sound to the left side of my car on my head unit i can hear very faint almost no sound coming from the speakers. another weird thing is that if i touch my white rca's to the inputs on my amp i can hear audible sound (but still very quiet) coming out of the speakers, but as soon as i plug it in i can't hear anything. sorry if i made this confusing, but i'm trying to give all of the details. any help would be great!
i should probably mention that i just tapped into my stock speaker wire to get signal from my headunit so i didn't have to take apart my dash, which would have been a real pain. from my amp i have all new speaker wire going to each speaker.
