I have a MTX TC8001 2400watt amp
2xP312d2- Rockford Fosgate P3's 12inch dual voice running 2ohms on my amp and the amp says it supports it even had the spots labeld for 2ohms and i have a rockford 1farad Capacitor.
I have the bass and Gain settings on my amp maybe a little less than half way up and i have my amp in a spot with PLENTY of windows i mean like 5 windows blowing on it and a fan and it will not stop overheating and shutting off... i can wait like 5 minutes and it will come back on. It takes about 30 mins to overheat. I dont no wat to do ? is my amp bad? i just bought everything brand new and i am using a complete StreetWire kit and 4gauge wires i checked all the wiring for the voltage and they all came back 12volts so they r fine but yet it still overheats? CAN ANYONE HELP ME PLZZ!? thanks
You say you have 2 p312d2 subs. Ok so the d2 stands for dual 2homs (2 X 2homs voice coils per sub) , conecting in parallel the 2 voice coils of only one sub will create 1hom load to the amp, and if your amp is 2homs stable per chanel that means you are lowering too much your homs causing the overhwating to it.
Your wire are to small going from speaker to amp and batteries to amp is and should be smaller then your ground get better wires .and first start with upgrading the wires from woofer to amp them get a bigger gage ground and watch the dif..
I think your amp 400watts rms per channel. is your amp mono? if it is mono and you have 2 subs hooked up. i think your subs are 500 rms each then the amp is working to hard and does not support for 2 subs you need 1000 watt rms combined or 500rms x 2 channels @ 2 ohms. so 1000 watt rms mono amp @ 2 ohms or a 2 channel amp with 500 watt rms per channel @ 2ohms. im sorry but your amp dose not work i know it say 2400Watt max but you dont run subs on maxx all the time you need to look at rms watts per channel at 2 ohms

dual voice coil subs hook up mono on amp, from amp - from right side + from left side of amp run to sub n then jumper wires from one side of sub to the other side goes negative jumps on positive and positive jumps on negative
im guessing both speakers are 4 ohms ..mtx 4ohms and kicker dual 4ohms..now if your amp can go down to 1 ohm wiring the kicker dual coils in parallel (2ohms) and the mtx connected together (4ohms) should leave you with a final impedance between 1 and 2 ohms ...i suggest you use one or get another
Well i tried looking up that amp, but Fosgate sight is down. So assuming that the best power out of your amp is 2ohms off the bridged hookup, and the subs are 4 ohms per coil, the best way is to only use one side of each speaker and hook it straight the the bridge. Only using one hook up wont hurt anything, its just for giving you wiring options. And when adding up ohms of speakers, it goes like this. If you had two 4 ohm subs, that'll give you a 2 ohm load. If you hooked up all your hookups, it would be like having four 4 ohm subs, and would give you a 1 ohm load.
Safe down to 2 ohms, NOT a 1 ohm stable amp, it will be pushing it hard even at 2ohms but Fosgate's should be able to handle it providing that the install and all cables,wire,connections,etc. are sanitary!
Good Luck !
This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.
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.
Overheating in amplifiers is often caused by a speaker load of too low impedance. If your L7 is a dual 4-ohm voice coil, and if you're using the amplifier in bridged mode, that may be causing your problem. Dual 4-ohm subs, with the voice coils wired in parallel, present a 2-ohm load to the amp. Your amp is capable of running a 2 ohm load in 2-channel mode, but not bridged mode.
The best fix with your equipment would be to re-wire the sub's voice coils in series, resulting in an 8-ohm load. The amplifier's power output will drop sharply, but you won't have problems with overheating in that configuration. There's a good chance that you'll still be able to get all the volume you want, even with an 8-ohm setup; otherwise you'll probably want to switch to a mono amp designed for a 2-ohm load.
