If it does it with no RCAs plugged in, the speakers or wiring need to be checked.

If the speakers and wiring are OK, the amp may have shorted output transistors.

I have the same sub combo. The problem is the amp is underpowered for the 2 MTX 12s, get a bigger amp and you should be fine.

MTX 8302 sound just quit on front speakers

hi Dan....Have you had any other service or installs shortly prior to the onset of clipping? In any case, the 8302 has Onboard Thermal Protection which is kicking in due to excessive heat. If you've had this running fine for a period of time, by that I mean at least a month, then we need to focus on why you're suddenly overheating......please update your post with any further information and progress.....good luck my friend

Amp and sub have been working great together then all of a sudden the amp is not putting out enough power to push the sub. MTX Thunder 311D

check to see if one of the RCA cables is unplugged or bad. check the gain check the sub level control on the deck if yours has one.

Subwoofer buldging out problem

When speakers are wired in the wrong way the will do the "pushing out" you're describing. Basically the polarities have been reversed and if kept like this over a period of time will blow the speaker. Best thing to do is to disconnect the power by the negative on the amp and take out the fuse from the power supply. Check the wires running from the amp to the subs, negative to negative and positive to positive. I know it sounds basic but many people do mix it up! I would also check to see what channels the subs have been wired into?

Best way is to have one sub from channel 1 and the other sub from channel 2 for example. Or if its a bridged 4 channel amp, have 1 sub running from channel 1&2, and the second sub running from channel 3&4 still making sure of the polarities. Again this all depending what kind of amp and sub you have.

-----------------------------
For example;
A 4 channel (bridged) 1000W amp. 250W max per channel or 500W per 2 channels! So if you have 2 500W subs, by connecting one to a single channel will decrease subs ability due to the lack of power supplied. However by combining 2 channels you optimize the output!
---------------------------

Once you know all your wiring from your amp to subs are ok/good connections/good wires etc you shouldnt have to "wiggle the wires" to get it to work as this is just a bad connection. Also ensure that no 2 wires are touching. Make sure that the master volume on the amp is turned down. You dont need this to be on loud at all, in fact far from it or you'll risk damaging both the amp and subs!

Hope this helps!

Subwoofer pushing out problem

it sounds like one channel in your amp had shorted and letting dc go to the speaker...a speaker is an electromagnet and requires ac to make it pulse..the amp has a blown channel and would have to be repaired and a factory service center...there is no quick fix..

Wiggle the positive wire to get power and have to unplug subs to turn car off

Ok it sounds to me that your remote wire is not hooked up right casue if you trun your car off then your amp should power down an when you trun your car on it should power up
