OK I have a Alpine 9807 Headunit Audiobahn A8000T sub amp and two alpine type E 12's. Whne i turn it up to 22 (depending on bass level) the head unit will turn off and turn back on. What the **** is going on. ANyone know what this is caused by and how to fix it??? We already tried upping the wattage on the radio fuse to 20A. Any other suggestions?

perhaps a lose ground ?

i bet it doesnt happen when you have only one of the subs hooked up

Don't mess with the fuse size on your head unit. You will fry it if anything shorts out! Sounds like a lose ground.

a loose ground on the radio?

that was happening when my alternator frist started going out. then my tach and speedo wouldnt work then it woiuld just die if i had anything on even headlights

its not the fuse or the ground cable... this is really common in big bass.. my car did the same thing.. when the headunit starts cutting off that meens that your alternator cant supply enough electricity... what u want to get is a Capacitor.. this stores electricity and uses it in big bass... they are pretty expensive.. u see i have 2 12" jl audio subs i put 2 small Capacitor because if it si one big it takes way too long to charge 2 small charge alot faster..
they look just like this one on the link...
Capacitor


anyways put those on and you wont have this problem again!

so 1 audiobanh amp and 2 type e subs needs a cap? i understand the need for a cap. but to me JLs or something like solos need it..

It doesn't really matter what subs you are using. Its the amount of current the amp is pulling. What is the ohm load on the amp and what sizes fuses does it have? But yeah it sounds like when the bass is hitting the amp is drawing too much of the power and this causes the head unit to shut down.

the amp is drawing 800 watts RMS at 2 ohms. The inline fuse is 80A.And the fuses in the amp itself are 2 30A fuses. Hope that helps any.
