aight well i have 2 dvc 4ohm mtx 5500's running off an alpine mrp-350 amp with an alpine headunit..the subs sound great with the bass at -7 (lowest setting) and sub control at +8(goes to 15) and the volume at around 20(not even 75% of the max)..as soon as i turn the volume or settings past any of that, the subs cut out and i have to turn off my headunit and turn it back on..i dont know if thats good or bad or what i need to fix it but any advice would help

How are the subs wired? How is the gain set?

turn bass to zero and sub to zero - then re-set your amp gain.
then see what happens

yeah well i did that and now my amp wont even turn on...i believe i have the subs wired to 2 ohms but my friend said that i have them wired wrong so the amp cant work with correctly..but first i have to figure out why the amp wont turn on now...the fuses are fine and i disconnected it from the subs..what else should i do?

disconnect the woofers and see if the amp will turn on and stay on

that is more or less the way to wire them.... the subs tho
it could be a gain issue or maybe even a bad ground...
