hi, Got a problem with the system i just installed.When running the sub and amp the head unit keeps turning off and then comes back on. i've checked the wiring nuthings wrong,i have installed many systems and never come across this problem. anyone ideas on the problem could be???

if the units getting to hot this may happen.

well only reason for it to not turn off is not enough current, try hard wire the ignition to the 12v so it's got solid power and see how that goes. i've seen some alpine units be very picky when it comes to power source - need good solid 12v.

it has a solid ground i have screwed it to the chassis, it is a brand new alpine CDE-9846E and still having the same probs

does the face blackout completely?

Check your earth! - 90% of the time it will be your earth!

dont use the oe earth, run an earth to one of the bolts on the stearing column and run your positive wire (constant power) to the battery making sure u put a fuse in within 20cm of the battery ( eg 15a) the only wires running to your headunit out of the factory loom should be the accesories wire and the ilumination wire - replace all others as fectory ones are shi t

man this is the exact problem i had with my head unit it turned off when say a beat came in and it was too loud turned out to be a fuse but what i didnt get was why would it work without 1 ? check the fuse's !!
