Just replace the old amp with another old but working amp if you're on a budget. If not, then just abandon the JBL stuff and run your own speaker wires (the JBL system is wired funny and won't sound right and put too much of a load on the new head unit if you use the stock wiring).My amp is bad....Is there an amp or adapter kit to plug a new amp in its place without turning to rocket science. Just need some tunes.....
Thanks ahead of time....
