Amp cuts off?

[enforcer 10+ year member]

i have a autotek 800xi pushing 2 infinity 1230 subs and it works perfectly when i first turn it on but randomly the amp will just cut off then randomly turn back on, the power light and the protect light both arent on. its not when i turn it up too loud or anything its just random.

any ideas for me to check out would be great because i am really confused.

also i just got a alpine cda-9847 and i dont know what i should tune the bass frequency to, any help on that would be great also.

Sounds like bad wiring somewhere, I would go over every square inch of all the wires and find what the problem is.

i talked to a guy at my work and he said i might need a capacitor? does this sound right? ive heard that they really dont do anything so i dont wanna buy one if i dont need it. i already replaced the inline fuse holder and upgraded the fuse to an 80 amp fuse? i really have no idea whats goin on

on the back of the box and its grounded on the seat bolt for the backseat

yeah just randomly not if i turn it up to much or change radio stations or anything just like in the middle of a song itll cut off and back on

my friend had the same problem and he took it to a shop and they went over the wires and found that the ground wasnt connected so well. they redid the ground connection wire and it worked fine after that.

I have a different problem i think tho my amp cuts out when i turn up the vol. maybe im not getting enough power?

Anyway good luck!

did they put the ground in the same spot or did they ground it in a different area of the car

Do ya have a clean ground? I'd check the wiring. Only time this happened I know of, is when my buddies amp was overheating.

what do you mean by a clean ground, i ran 4 ga into a ring terminal and bolted the seat back down through the ring

clean ground = good metal to metal contact, no paint or anything in between

he probably meant is there any paint on the metal?, surface rust?, etc

ok i checked and there was paint under my ground so i scratched it off so it was bare metal and hooked it back up but its still doing the same problem, i checked the fuse holder again and it kinda seems that the power wire isnt touching the fuse sometimes? is there a way to keep the wire in constant contact with the fuse?

have you replaced the fuse? sometimes the fuses will look like they are still good, but they really arent.

yeah ive replaced it a few times, its not like the bass doesnt come on at all it just cuts in and out, what i was sayin was that when i look through the fuse holder the power wires dont look like their touching the fuse, like one is and one slides a little bit and when it slides it comes out of contact with the fuse is there a way to keep the power cable from sliding out of contact with the fuse
