Step 1:

Press and HOLD the A.ADJ (Audio Adjust) button for 1 sec. to enter audio control mode.

Step 2:

Press either FM (or AM) button to select the mode you wish to adjust. Keep pressing until you find the mode you require (in this case, it will be BL for Balance).

To change the value, press the Down Search or Up Search button to your desired setting. Centre balance is "0", negative number is Left speaker, Positive number is Right speaker.

Step 3:

Repeat Step 2 to select the TREBLE (TRE) mode, then use Down, or Up keys to change the value.


Hope this helps.

Cheers,

Scott

You could add a switch to control the power going to the head unit. I have seen this done in many different vehicles where the head unit drains the battery, even when supposedly off.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

probably not

sounds like it could be either a bad speaker, a shorted speaker wire, or a bad output ic inside the deck.

what do you mean by one set is a hard wire and other is an rca jack?the hard wires go to the speakers and the rca is wired to an amplifier of some sort which is wired off to more speakers or subwoofer(s)

Contact a stereo shop. they should be able to get you an adapter that will interface it with the amp.

mechanism out of siychrony.....you need a nearest technical support.
