system cutting out please help.

[baseballn08]

I have a 2009 mustang. I have 2 alpine type x 10's (sealed box) rated 1000rms each. Power acoustik crypt 4000D amp rated at 2200rms (wired down to 1 ohm). I have a alpine mrp-f600 wired to 4 alpine type R 6 1/2s. I have 4 gauge power and ground wires. 10 gauge speaker wire to the subs. When I go to turn up the volume (amp at about half gain) all audio will cut out, both bass and music. But both amps keep power and so does my headunit. The only way to get the sound back is to turn my car off and back on. I have a stock alt and battery. Any suggestions?

thanks

your amps are going into protect... what HU are you running?

the factory amps are going into protect. i bet he is using the stock deck and stock amps to get signal to his real amps.

yea... thats what i was sayin.... sorry wasnt being specific... if your running stock HU, are you using a line converter? and if an aftermarket, did you bypass your factory amps?

i have the pioneer f700bt. I had it hooked up in a shop a while back. Not sure how they ran the wires. Both amps keep normal power and dont go into protect mode.

sounds like the deck is going into protection. kenwoods do it , not sure about pioneers though.

decks have a protection? never heard of that lol. Even if it keeps normal power as well? and the little bit of play I can get out of it it doesnt seem to be as loud as it should be considering its 2000rms.. Any suggestions on what to do to fix it?

that PA amp is not putting out 2000 watts bro... sorry to tell you, but their over rated...

as far as the HU, take it back to the shop that installed it... very easy for an installer to not crimp a wire right, and then you end up getting a short, which will put the HU into protect

wouldnt the headunit lose power if it were going into protect? because it stays powered as normal and keeps its image and all, just no sound.

not always... sometimes the audio circuit and lcd circuit are ran separate, so it could be in protect, and still be "on" ...

like i said, take it back to the shop that installed it... any reputable shop will go back over their work at no charge, if they did something wrong

ok, hopefully an easy fix, i have been getting a bunch of bs answers on different sites. Thanks a lot

well i had all the wires checked and im going to test it out throughout the day and see if it cuts out. Since you say PA is overrated what do you think its actually pushing?
