New head unit. no sound

paintslinga2010 · Jul 5, 2010

I took out the ancient alpine setup i had because the volume dial was fugged. So i use the same wiring harness and everything and i cannot get any sound from the speakers. It boots up fine and functions but makes zero sound. Is there a fuse or something i could have blown? Im at a loss here.

Thanks

shouldnt be a fuse for just audio...hmm...Any speaker wires come unplugged while putting the unit back in?

double check that the wiring hrns was the same, if one of the speaker wires is grounded out it will have no output.

Also if you have a mach system in the car be sure the blue remote turn on wire is connected.

so all you have to do when using an aftermarket radio to keep the mach amps and speakers is connect the amp wire??

Does it sound the same? better? Than the mach head unit?

Thats why I'm scared to mess with mine lol Its not the best factory system, but its better than nothing!!

integrating a deck into the mach system is one of the easiest premium systems you will ever get to work with. With a few tweeks depending on what equipment you use the mach system can sound much better with a new deck. I cover the majority of it on page 2 of my cardomain page. Let us know if you have any specific questions...
