System shutting off at high volumes.

[ttt0649 10+ year member]

2004 Honda Civic Coupe

Alpine CDA 9835

Alpine Type R Comps and 6x9s - Alpine PDX 400.1 amp.

1 - 12 inch Diyma Sub - Alpine PDX 600.1 (Gain is set at normal).

System shuts off at 16 volume or higher (depending on the song). Usually songs with more hard hitting bass shuts off right at 16.

Im assuming that my battery/alternator can not handle the voltage/amps output? Going to do the 3 big upgrade tomorrow and see what happens.

Am I right or is something else causing this? Any advice would be appreciated.

Thanks!

Yup, probably dropping the voltage too low.

sounds like your getting low voltage. So your heading in the right direction. Not sure on your alts output but its probably pretty low

ie clipping I always set my gain to "normal", but recheck it.

definitely low voltage. Your head unit will turn off if it gets too low.

It's low voltage because your gain is set too high.

you might want to check your ground

I'd try lowering the gains. That HU's volume goes to ~35, correct?

Well, my gain is on normal but i will set it lower and see what happens.

My car has gotten more sluggish since installing my system as well and I have notice a decrease in my gas mileage.

If the 3 big upgrade does not help. What else what ya recommend?

That's kind of suprising, what kind of drop in gas mileage? Heck, I still get around 29 mpg with city driving

Sounds like you may have a more serious problem with the car. 1000w is a good amount of power, but I doubt it should be raping your car like that. Maybe I'm wrong, though.

check all your connections, those amps shouldn't give you problems like that on stock electrical.

What do u mean by normal. Set ur gain uses a dmm, this will rule it out.

Do the big 3 after, if the gain doesn't help out.

Maybe it's on nominal. That's my guess.
