I have hooked up many systems before but this is a low cost build and wantto keep the factory look. Please help! Also do I need to hook up my remote wire anywhere?

Answer 1

yellow to white/black ( or left - )

brown to white (or left + )

light blue to gray/black ( right - )

dark blue to gray ( right + )



the yellow - brown - light blue - dark blue will be in a row on the factory plug . there is another yellow that is a power wire so be careful not to tap it. if these colors are not right then you will have to let us know what model car it is.

Answer 4

I have that part and have installed it before. So were only going one subwoofer channel here right? Alright first go to your speaker wires. Find the wire for either the front of the rear. Look up your cars harness for which wires are which. From there you will use either T taps or splice into the wire. Run those wires into the wire slots on the input side of the line output converter. You should only need 4 wires into the line output converter then just use the 1 side of RCA's on the box to plug into the RCA cables. As for your remote wire, break out the multimeter and find a wire the doesn't turn on until your car is on, usually these are things like power antenna wires and ignition wires, I usually use the ignition wire. Just break out your multimeter and start testing til you find one, then just splice into that wire.

Hope this helps, if you have any issues just message me.
