    Ok so I basically know nothing about systems but im trying. I currently have two MTX 15's and a MTX Thunder 942 amp. My problem is the second i hit the crossover switch my subs blar even if the volumes on 1, its like static but car shaking. I had a problem with a different setup where my subs would like make a pulsating sound when not turned up, so i got 10 gauge wire and it fixed it. I think the problem right now is I have 10 gauge power and ground wire when I should have 4-6. Sorry if that makes no sense I tried.

    # 235 watts RMS x 2 at 4 ohms
    # 470 watts RMS x 2 at 2 ohms
    # 940 watts RMS x 1 bridged output at 4 ohms
    # stereo or bridged mono output
    # 4-ohm stable in bridged mode

    Well I have a 1000w pioneer something and it sucks, but at least it worked. Hooked up the MTX started my car blew a fuse instantly, replaced the fuse, diden't blow but thats when i realized my subs went ape **** when powered to the amp. You guys think getting 4-6 gauge wires for power and ground would fix the problem?

    run at least 4gauge power wire to the amp, and for the ground do the same.
    where do you have your amp grounded to and is it bare metal

    how are your subs wired to the amp? do you know the impedance they are showing the amp? maybe its at a load the amp can not support. i.e 1 ohm mono maybe?

    what is their coil configuration?

    Well like i said i know nothing, but I can tell you the amp and subs did work together before. It was my uncles setup and worked fine until i tried the amp in my car. Im going to redo all the wiring with 4awg tomorrow if it doesen't change anything ill let you guys know.

    ok, make sure your connections ARE tight too. bare metal surface not on painted surface for your ground.

    a proper flow of power is very important.
