Could not find anything regarding the subject.
I can't remove the HU (with built in AMP) due to the bus thing from GM, every thing will be disabled. So, the work around is to add a separate, secondary AMP for the carputer. question is, is it safe to connect the secondary AMP to the same speaker feed by the HU. I promise not to turn the HU on while the PC is on.
Who the hell is general failure?!?
And what the f@#k is he doing reading my drive C:\?
I agree, the relay is a much better idea. You might need to get a few of them, one DPDT for each speaker. If you get ones that have a 12v coil, then you could have them energize when the computer powers up. Run them off of a HDD power connector. Then when the computer is on, the relays switch the speakers to the computer. Turn off the computer and the relay switches back to the HU.
