My amp keeps shuttin off

[Beamonesque]

My amp just shuts off sometimes on me, I don't have the volume up loud, and sometimes all i have to do is turn off then on the head unit. Sometimes that doesn't work tho and I just sit there listening to bassless music until it just magically turns back on. Anyone had/have this problem?

check your ground on your amp

It is currently happening to my rockford 1500bd, I bought a new alternator (150amps), change the wires, moved ground, even lowered gain, and it still does the same thing..

check the impedence on the subs as well

what gauge wire, you should have at least 4 gauge ran to the amp and to the ground.

[oibone781]

i have a 4guage running into a splitter that turns in to two 8s for the power, and a 4 guage ground wire that is on the seat belt screw...

maybe it is as simple as a bad connection on the battery...either that or it just plain ol isn'st gettin enough power

what is the impedance load?

[finese1]

If your subs a bridged you are probably overloading the amp. I'm guessing you didn't bridge the amp.

[finese1]

If your subs are bridged you are probably overloading the amp. I'm guessing you are running the subs at 1ohm when you bridged them, and have the amp running at 4ohms. To bridge the rockford I think it is the left - and right +. That will get you 1ohm.

This amp is only rated for 2 Ohm Imp.

So what Subs are you running the amp on and how are they wired up?

4ohm amp going into two 10's at 4ohms (not bridged), so shouldn't be an overload problem.

[oibone781]

I have dual 2 ohm woofers, and have mine wired in 2ohms, according to the voltmeter and the manual

Is the amp hot when it shut off? Did you turn on low pass filter? Feeding high freq to sub is just wasting power. Where the gain setting at the amp? Turn the gain all the way down, set deck at highest volume without distortion, disconnect/turn off all speakers, increase gain to sub until it won't get any louder or start to distort (its kinda hard to tell if its distorting, usually sub won't get as loud after a certain point), turn it back a bit.

I didn't realize there are 2 people with this problem here.

oibone781:
Your amp is rating for 2 Ohms only. If you have 2 Subs at 2 Ohms they can only be loaded at the Amp 1 Ohm or 4 Ohm.
