subwoofer cuts out at higher volume

[hazmat404]

well i finally got everything working on my stereo so i decided to try the subwoofer again. well it works at much lower volumes then it cuts out when i start to turn it up. its an mtx 250d amp and an infinity 10" kappa perfect. worked perfectly fine in my old stang and this stang is the exact same setup except instead of the speaker wire going into the aftermarket headunit, its tapped into one of the rear 5" speakers (very cleanly done).

not sure if its being overloaded or something but it will not play past a certain volume, then i turn down the volume down to a lower level after it cuts out and it will start back up after a second. any ideas to what might be happening to it and hopefully be able to make it work all the time?

try turning the gain down on the amp, sounds like it is going into over load protection. could also be to strong of a signal from the stereo.

Check and make sure the Impedance is matched on the Amp and the Sub. The Amp may be going into protection mode, if the impedance is too low.

Thats called clipping....either your amp isn't getting enough voltage, or is over heating.

After you check everything else mentioned, do not overlook the power connections. Make certain you have a clean chassis ground the the proper gauge cable from the battery terminal or power block. An amplifiers power supply must be able to draw the proper amount of amperage required. This could also cause the amp to go into protection as well.

well i turned down the gain a good bit and it still is doing it. the amp never overheated before and i literally took it and the sub outta one car and put in the other (about 2 months back but never hooked it up). never ever had a single problem with it before but it was an aftermarket h/u and had rca's all the way from the h/u to the amp.

how do i go about making sure the amp gets the voltage it needs? im going to double check the ground and any other connections but i wanna say everything is pretty clean but i will make sure.
