replacing HU w/ carPC.. audio->car speakers setup?
i have asked this question before and people suggested I get an amplifier and plug the sound card to the signal input on the amplifier.
I'm not looking for real performance, but I just want to be able to get decent sound by using the audio wire harness from the back of the car to my carPC.
Instead of spending 100+ on an amp, why can't I use something like what aftermarket headunits do... don't they have an amp built into it? If so, couldn't I just get a PCB amplifier and use that?
pc audio out -> pcb amp -> car audio wire harness -> speakers.
Should I be looking for a 4 channel 20-25W amp then? alright thanks.
