I'm going to be installing my 'carputer' (heh, still can't say that word without a chuckle!) in my dad's Accord for now, until I get my own car, so it brings up a lot of issues. One is, I don't want to replace the head unit (money issues, heh), and I'd like to just use a 4-channel amp instead. But, I'm sure my dad would like to keep using the current radio, so I want to have both connected up to the amp. I'm thinking this could cause problems if both the amp and the radio were outputting power at the same time, or something. So, I should probably use a switch, right? What about relays? I'm worried that electromechanical relays might add some noise to the signal path, but I don't know. I suppose that if this is a problem, I could just use semiconductor relays. What do all of you think?
No announcement yet.
Radio and amp connected to speakers at the same time...
