Q: Why am I not getting any sound from my speakers?
A: If you’re not getting any sound from your speakers, check that the wiring for each speaker is connected properly and that the speakers themselves are functioning. You can also test the voltage at each speaker using a multimeter.
Q: Can I install an aftermarket radio in my PT Cruiser?
A: Yes, you can. However, you’ll need to use a wiring harness adapter to connect the new radio to the factory wiring. You may also need to purchase a dash kit to fit the new radio into the PT Cruiser’s radio bezel.
Q: Can I install a subwoofer in my PT Cruiser?

Q: Do I need special tools to install a radio in my PT Cruiser?
