    use the mtx for the 4 stockers (probably will blow them pretty quick but then you get an excuse to upgrade) and the rockford amp to the rockford sub.

      I don't see any reason to use the Pioneer amp at all in your setup. run each stock speaker off of the 4244 and run the sub off the 325.1

      for your power wires: the 325.1 uses a 40A fuse, the 4244 uses two 25A fuses (=50A), so your power wire needs to be able to handle ~90A. you can use a 4awg (or thicker) power cable from the battery to a 2-fuse distribution block, and you can run 8awg (or thicker) power cables from the distribution block to each amplifier. (or you could run two separate power cables).

      good luckl

        Ya, this is what I've been running for the last year but I picked up the Pioneer amplifier thinking I could use it in my system. Oh well, guess I'll throw in in the closet. Thanks!

          well, you can use it if you really want to...

          you can use it to replace one of your other amps (which would be pointless as they areboth more powerful then the Pioneer amp), or you can add two more speakers and use the Pioneer amp to drive them.
