Protection Mode?

[YungGunna313 10+ year member]

Ok i posted earlier about florida heat being a *****, but now i think i have a serious problem. my amp (phoenix gold octane R15.0:1) finally cooled down cuz i unhooked it n brought it into my house for airconditioning. i put the wires back up and the amp doesnt turn on. i used a dmm to check tha current and voltage and everything is fine, the only thing is that there is nothing coming out of tha speaker outs voltage/current wise. i dont kno what seems to be the problem. i thought it was an overheating problem. but it might not be, can anyone help me? asap plz cuz i gotta go out soon.

btw im running 2 alum12q's on it. wired each sub to 3 ohms, theres 2 speaker outs even tho its a mono so i just wired them like a 2 channel. the amp is running off 5 awg wire. the ground is fine, and nothing else seems to be wrong, the subs arent blown because they dont move period and they were working fine. can anyone plz help me?

im confused.

Pretty sure he means that he checked the REM line and the power fromt he battery, (I hope he means that.)

If there is nothing visually wrong with any compents in the amp, then it SHOULD not be fried. Check the underside of the board and all, carefully. If you see ANY black marks at all on the board or any components, replace the part. Also, once you get it working again, make sure that you do not use the bass boost at all. And is the amp even turning on?

no the amp doesnt even turn on, thats the problem im having, i checked the board, everything is clean, no marks or nothin, i did have the bass boost up halfway, but it was fine... oh yea n btw when i said i checkd things wit the dmm, i was checkin to see if there was current/voltage goin into the amp to give it power... but it just wont turn on, power is fine it just wont turn on...... =(

Sounds like a REM problem. Did you check the REM wire for a live current when the HU is on?

I still have the crappy sony head unit that came with my car, and the remote wire went out. Just use the red wire instead, and you should be fine. Or just look into another hu.

One question, pertaining to why it might have shut off in the first place, did you turn the bass boost on before or after setting your gains? I know i made the stupid mistake of turning the boost up after i set the gains //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif .
