Speakers shut off at higher volumes?

[Chim]

Hey...

Here is my issue.. I installed a brand new alpine HU, with a brand new 12" kicker, and a brand new 4 channel amp, with a set of 6x9s.

The 6x9s are run off of channels 1 and 2, and the sub is bridged from channels 3 and 4...

It all sounds great till I crank it really loud and hard bass lines really start pounding, then it all just shuts off.. I can turn the HU off and then turn it right back down and it works again...

All parts are brand new.. any ideas? I have double checked my grounds and power and speaker wires, and now Im at a loss...

Please help!

what model amp? what size power wire? need some more info

check how you wired your sub, possible to low of an ohm load. what vc is the sub? usually on 4 ch's you can only go down to 2 ohms bridged.

The Sub is a Kicker CVR 12 - wired parallel.. Im not sure if its 1 or 2 ohm...

The Amp is a EFX - HD4004 - bridgeable 2/3/4 Channels

It has a low impedence 2 ohm capability

Power and ground are heavy gage wire.. its almost too fat to squeeze into the terminals.

i don't know the specs on that amp but if you have the amp seeing a 1 ohm load it probably can't go that low. check impedence on subs coils

you should have a single 2 or a dual 4 ohm coils to have it match your amp. sounds like your sure its a dual 1 or 2 though? that could be your problem.

this is how I have the sub wired.. it doesnt really say if its 1 or 2 ohm...

look on the rear of the subs it will say on the sticker. if it is dual 4 ohm you will need to wire the subs series-parrallel

MOST amps are only stable to 4 ohms bridged.

He is only running 1 sub.

You need to wire the sub in SERIES, not parallel. you are running that amp WAY below its rating if its a D2, and below its rating if its a D4...
