1.-check proper heat sink, or dissipation.
2.- check speaker impedance. Must match between amp and speakers.
3.-low power line on the house may cause low efficience work on the amp, overheat, and finally fuse protection.
4.- finally, check speaker wires. Thin cable overheat amp too.
on some amps there is a duel light. red and green usually. red means it is in protect mode or you didn't hook up your remote wire. if in protect mode, it could mean a number of things. did you hook it up with speakers and everything?
okay, first thing i would do is turn down your gain. Sounds like you are over working the amp thats wire your amp gets hot and shut off, it's going into protection mode. Is your amp enough for your subs. Some times not getting enough power to your amp might do this too. But if your subs wattage is way over your amp watts, you need to upgrade your amp. Also check your subs and see how the are wired up with the ohms, And see if your amp can take a 1 ohm stable load or how ever it's wired up at. hope this was helpfull.
If you have proof of purchase(invoice or receipt) showing the purchase date and you are still within the warranty period then yes it would be repaired by MTX under the warranty guidlines, and by the way MTX is great at customer service and they are great to work with(very fair)!!!!
Keep in mind that the seal on the bottom of the amp cannot be broken or that will void warranty coverage.
Give them a call, you will be glad you did! 800 225 5689 - MTX Customer Service & Amplifier Service Center Good luck !
Make sure that your connection at the battery is still good-sometimes the wire corrodes up front when your system is installed for a long time-so check that out and of course the fuse that you installed a foot away from the battery so that you dont burn your vehicle down if a short occurs somewhere down the line
I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.
My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.
First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.
