I just bought a pair of 6x9 speaker to replace the factory rear speaker in my 89 Honda accord.But I cantget any sound out of them. the front speaker work fine but the rear dont. The factory rear speaker just went out one day while I was driving. Whats the problem?
Sounds like you have a bad connection. If you kno the backs are wired up right, then the connection must be up at the HU. Do you have an aftermarket HU, or the stock one? If it's stock, then the HU is probably bad. If it's aftermarket, mke sure all of the connections are good.
Colors do not matter. Even if he mixed up positive and negative they would still work. But yea, sounds like a bad connection behind the HU. Pull it out and check.
