I'm upgrading the amp in my car and the two new amplifiers are going in the same place as the stock amp. There's already a 12v line from the factory amp, but I have two amps to run. Would there be any issue with just soldering on a second wire to the existing 12v line and running it to the second amp? Sorry if this is a stupid question I'm really new to this stuff. Do I need a power distribution block instead?
