Is the amp for the doors and fronts next to the sub amp or is it actually just a single amp system? Haven’t dissected anything yet.
Yes...except...the pillar tweeters and center speaker are run of a small amp in / under the dash. so when you remove and replace the big factory amp, no signal is sent to the smal amp. thats why you have to run new wires to the tweeters in the pillar, and why nobody puts in a center speaker....it is no longer needed.
