No Radio Balance [SOLVED]
 

This is more to tell everyone what a potential issue is with installing a after market deck

So I just got a 1990 F-250 the deck in it was dead but had a proper wiring harness adapter so I went out bought a new deck and speakers but after the install I had no balance control and the back of the new deck seemed to be getting warmer than id expect(almost to hot to touch) also there was a fair bit of popping from the new speakers.

Turns out the ground wires for the speakers are backwards so I had to connect the Left Front Speaker Negative(white/black) from radio to the Grey/Black of the adapter and the Right Front Speaker Negative(grey/black) to the white/black of the adapter.

Since my truck doesn't have rear speakers I didn't cross those grounds but Id imagine you would need to if you had rear speakers but check if there is an issue balancing them left/right first.

When I searched this issue online I read about 20 threads that the end result was to just install new speaker wiring turns out this isn't needed!

Typically, you'd want to install new wires if you were going to a higher wattage system, if powering the speakers directly from the receiver, your existing wires are fine, as long as they are in good shape.
