How do u make an aftermarket head unti remember ur preset configurations?

Question

I have a 98 sunfire 4dr. and i put in a new head unit cd player. but everytime i turn off the car, the bass and treble and loud goes back to preset. it wont stay where i want it to. help me!

Answer 1

It's not wired correctly.  The CD player's yellow wire needs to be connected to a constant voltage source, and the red wire needs to be connected to a key-switched source.  It sounds like the two wires are reversed.
