it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.
The more amp you are pushing the better. Better too much amp then not enough. How many watts per speaker? less then the amp I hope. When you need decibles the more air you push the louder it will be. Enclose in a MDFB enclosure or plexiglass and feed towards each other and port the box to the sides. This will cause some annoyance. We ran 2 rockforts @1000 watts and abtained 137dc before the back windshield blow out,,lol
I would stick with Kicker or MTX. The best place in my mind to get them is soncelectronix.com
Just try to mach the specs as close as possible. Make sure to look at the recommendations of the subs for the size of the box and the port volume.
ok, connect the amp positive to the positive end of one sub coil, take the negative of that coil, and run it to the positive of the second sub coil, then run the negative out of the second sub coil to the negative of the amp.
i recomend you just use the best single woofer in a well built box and that will give you better sound at lower gain volumes it sounds like you have too much junk laying around but to get good bass run your sub at 2 ohms if the amp is stable at that impedence
I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.
if you wire the subs in parallel you would achieve 2 ohms which would theritically double your rms, sadly this isn't the case what with wire resistance and such you might get around 270 rms still not that bad. to wire in parellel you run a positive off the amp to the positive on one sub then run a wire from the first subs negative to the second subs positive the run from the second subs negative to the amps negative and bam 2 ohms but be warned this will put more stress on your amp and cause it to heat up faster. peace bro and best of luck
