JVC Head Unit Installation

[smashedpumpkins 10+ year member]

I'm installing a JVC KD-R520 with 4 door speakers. I've wired up all the speakers to the head unit but I've having a problem...

When the unit turns on it says "MISWIRING CHK WIRING". Everything I've read online says it has to do with the speaker wiring being installed badly. When the unit turns on the back right speaker pops. No other speaker pops so I assume it's the culprit. I've checked everything but it seems perfect to me. The wires are soldered then wrapped with electrical tape. When I take a 9v battery to the wire at the headunit the speaker pops just like the rest of them. I changed the head unit ground as well but it's still giving me the error. Is there anything else that might be causing the miswiring? Does the back right speaker popping have to do with it?

Possibly one speaker wire somewhere is shorted to ground or to another wire. Remove all speaker connections at the back of the HU and measure resistance between each pair and to ground. Then connect them up one at a time.

Finally got it working. Darn panel was pinching a wire...

I've tried everything to get my Peripheral Steering Wheel Controls PESWIAKJC to work with this JVC unit but it's a no go for some reason. It worked great for my Kenwood but maybe this JVC unit isn't compatible. It seems that the unit says it should work with JVC but it doesn't list specific models. I've tried programming the device several times and I'm positive it's programmed right. The device even lights up each time I press the button on the steering wheel but the JVC unit doesn't flinch.

Glad the speakers at least finally work. That ended up being more of a pain that I had expected.
