I have a spare factory amps that came out of my son's car, and was curious if it's possible to run two factory amps. One for the front speakers and one for the rear?
How does a 4 channel amp work with 8 speakers? What's the layout?HI welcome,
Yes it is, but you are going to find that it is so complicated trying to match outputs and inputs. Also do you want to go with a 2 or 4Ohm for the speaker. It's much easier to get a 4ch amp 800 – 1000 watt to replace both of them.
Er... not to jack a thread, but that would be series wiring, which doubles the resistance. Two 4 Ohm speakers wired in series as described will result in 8 Ohm at the amp. To get 2 Ohm resistance from two 4 Ohm speakers, you wire them in parallel, positive to positive, negative to negative.Yes, it's a matter of getting the Ohm right. With a 4ch amp running at 2 Ohm (say driver side door) the (+)from the amp goes to the (+) of the 1st 6' voice door speaker. While the (-) connected to the (+) of the 2nd speaker, then the (-) of the speaker connects back to the amp. Doing it this way, you can run 2x _ 4 Ohm speakers at a stable 2 Ohm.
That's backwards though, is what I mean... you described series wiring, which would result in 8 Ohm resistance from the two 4 Ohm speakers. Two 4 Ohm speakers wired in parallel = 2 Ohm. Two 4 Ohm speakers wired in series = 8 Ohm.Ok, if you wire them in parallel, positive to positive, negative to negative, yes it will go to 8 Ohm, but you won't get the volume (sound) out of them. You would need to wire a third 4 Ohm speaker in series, so to bring the Ohm back down to 4 Ohm to make it sound better. Remember the higher the Ohm's the lower the sound. T
