my 2500d keeps cutting off! HELP

[Chriscivic 10+ year member]

just got my 2500d put in today along with my two h2 15's and whenever i turn the volume up past a certain point the amp cuts out and then comes back on in a few seconds. it's in a 02 honda civic. i am running 0 gauge split into two 4 gauge wires for both the grounds and battery on the amp. the subs are wired to 0.5 ohm. i have double check all w iring including the subs and alln wiring is perfect. i even switched out the rcas to see if that was the problem. any ideas? also when the volume is at 0 and the amp is on i get a faint noise coming from the subs, it is real high pitched. anyone got any ideas?

Check your voltage at the amp....are you getting dimming?

does the amp have low voltage protection? will it cut off if it goes too low?

What type of battery do you have under the hood?

This stopped that problem for me and it was a total of 3 bat's and I still had some faint dim but nothing like it was with one.

its between 700-900 cca, its from wal-mart, the biggest battery they carry.

Big three done?

you need to upgrade that battery under your hood and you should put a battery in the back on the system

Do you not have an HO alt? If not, youre stupid for asking this question. Trying to run a 2500w amplifier at half an ohm, without even the Big Three or an upgraded battery...

Theres one.

How about the others?

 

[Chriscivic 10+ year member]

others are not upgrades, but w/o those it should still be able to play without cutting out. no i have the stock alt.
