I have a 2 channel amp at the moment running the sub and it does a pretty decent job....
I now want to buy a 4 channel amp to run the front and rear speakers inside the car.
At the moment I'm running a cheap sony explode head unit with 1 x rca output and going to upgrade.
Question is do I need to get a head unit with 3 x rca outputs or can I get one with 2 x rca's and run the rear speaker rca's and then split them to run the sub amp and to the 4 channel amp for the rear speakers? Is that ok to do that?
Also anyone have any idea the factory front speaker size for a 1992 Mazda familia sedan with wind up windows (if that matters)?
