Help: Subs cut out when hitting hard

[deadmanrob 10+ year member]

Hey guys when i crank it a decent amount on a song with alot of bass it seems to cut the subs after hitting for about 10-20 seconds. like the amp just turns off. If i switch the song it comes right back and somtimes during the song it will happen then the song will have a brief period where there is no bass and it will come back when it hits again. any ideas what may be going on?

thats the amp i have if it helps

voltage drop amp goes into temporary protection mode??? not sure just throwing it out.

may be low impedance too,or low voltage

wow so i actually made sense for once lol

pretty much

Is any of these reasons helped if i get a capacitor?

very much *not* so.

Solution to that would be better electrical.

No, a capcitor will not help you. Caps will never help you and are a waste of money. Your problem sounds like an impedance problem, you are trying to run an ohm load that is less than what the amp is stable for.

as in stopping my lights from dimming?

That and too low of a voltage, in which needed better wires/alternator (you should probably do the Big 3)

Well i keep getting the mixed msg's of how horrid caps are and **** and before i came on this site its always been about how good they are so i never know. the wires i think are fine but yes i am considering going from my stock alt to a 95a

Caps do help, but not nearly as much as the price u spend on them for the money you spend on a cap u could buy a cheap battery that will do no exageration 50x better minimum. Now to your problem, that is not enough power you are running for low voltage issues. I am willing to bet you are wired down too low of an ohm load for that amp. Other problem could be you have the bass boost and gain completly maxed.

if you alt is smaller than 100amps u definitely are having bad voltage drop throwing the amp into protect. do the big 3 in 0awg and 4 awg to the amp then see how bad your dimming is you will still need a high-output alt but this will help quite a bit. double check your grounds as well make sure its a good metal to metal connection.
