I have 4 MTX 10s and a JL 1400D amp and it cuts off if i turn it up to bang it what do i do

Check for a speaker wire that come come of , Or a loose grond wire on the amp or where ever you have the ground wire connected two,

yea the jl either setup will be good for those woofers but for the money an to get the power i would try a hifonics 2000 or the 2600 brutis or mtx or2 poweraqustic 4000 planet audio they will work great or give me a call there are a lot of amps to choose for the money an the power

your aux cords could be craked or cut somwhere

the amp is under to much pressure get a bigger 1

your subwoofer is wired incorrectly to your amplifier. Figure out which ohm load of subs you have and then what ohm load options your amp is stable at. Next go to either the Crutchfield website. find their learning center. go to subwoofer wiring diagrams. or go to www.the12volt.com and find their section on it

Did some research and it sounds like a wicked lil amp with clean clean sound-its hard to say what subs to tell you to run because everyone has different taste- and without knowing what your setup is going to be theres no real way to actually say-the amp is made to run 3 channels -so focusing on the sub channel only i personally say get a pair of 10s or a good 12-your not throwing a ton of power so you dont have to go balls out on the subs- i personally like MTX subs and xtant is made by MTX so that wouldnt be far from home -good luck with that

you may only be able to get but so much out of the subs. If you turn the bass down a little so the that you dont drive the subs so hard you may get a little more wattage out of them

HI DUDE .. U CAN ONLY SINGLE PC OF JL SUB BY BRIDGE MODE ... COZ UR MTX AMP HAVE 300WATTS RMS ....

If you are looking for some serious sound try using a Rockford Fosgate P3001T Amplifier.. it pushes 3000W Max its a 4 channel amplifier. Or you could go with something small. I have two JL Audio 10s in my car running with a 600W 2 Channel MTX Amp.

Run a Jumper from coil 1 + to coil 2 + and a jumper from coil 1 - to coil 2 - and then run + from coil 1 to amp and - from coil 2 to amp. This will put your load to 3 Ohm and that will give you the most power. You could get more by going to 1 ohm but I don't think the mtx amps are stable at 1 ohm.
