headunit preamp gone bad?


Recommended Posts

so you have only one set of rca's connected to your headunit and they are going to the sub amp? if your phone has a headphone jack/connection get/borrow a cord that had a headphone jack to rca connection and plug it straight into your amp. have you tried moving things around near your amp while it's doing this? is the sound coming from the speakers that are run from the headunit or the amp.... need more info to help more sorry man

correct i only am using the sub channel and its going to my fahrenheit amp thats connect sub, and the pulsing is only coming from the speaker connected to the rca output from the back of the headunit, but like i said when i used the front l and r output and rear l and r it did not do it when i hocked up the full range speaker and amp

also worth trying to see if it does it with just a cd or usb without letting your phone connect to it via Bluetooth............ if ya cant be bother'd trying all this stuff just grab another deck and hope it goes away

:P
