distinktbean Posted January 17, 2012 Report Share Posted January 17, 2012 (edited) My wifes car has a punch 1000 amp that powers an AQ HDC3 wired down to half ohm, but here lately it has started to go into safe mode but i can not figure out why. i have already checked all of the fuses and checked the voltage (which is staying stable). any suggestions on what might be going wrong or is the amp just done with its life its gone threw three different systems, my wifes being the third, each at about a year a piece. the amp will stay on if it is not played loud with the gain about half. if the the remote gain knob is turned up all the way it wont go past 40 out of 60 on the volume on the stereo. itll go about 50 out of 60 at half remote gain knob depending on the song.

vans113 Posted January 17, 2012 Report Share Posted January 17, 2012 check and double check your voice coils in your subs a bad voice coil can easily make an amp go into safe mode, and also your gain should be all the way up, thats just begging for a blown sub Quote Link to comment Share on other sites More sharing options...
distinktbean Posted January 17, 2012 Author Report Share Posted January 17, 2012 (edited) the amp has a remote gain knob to turn it up and down, but the system is tuned with a scope so i know im not running it at full all out full gain. i do know that much.

t-money Posted January 17, 2012 Report Share Posted January 17, 2012 the coils are dead on .5 ohm. voltage stays in the 14's. but the amp goes into protect then if u turn it down a little bit it comes back on. i think its the amp. i have looked at it personaly thats all i can come up with Quote 2002 ford focus hatch pioneer DEH-P8400bh infinity kappa 6.5 components front and rear XS Power D1200 Shuriken BT-100 audioque 120.4 2 15 inch audioque HDC3 D2 2 audioque 2200d big 3 mechman 220a alt with external regulator 479-418-3056 Link to comment Share on other sites More sharing options...

Guest Posted January 17, 2012 Report Share Posted January 17, 2012 I believe rockfords go into protect anything lower than .7 its been fine for 3 months or so at .5 if you believe that the amp sees .5 at all times while playing music, you must be insane. only reason that amp has been working (and probably the reason why its not working right now) is because of box rise Quote Link to comment Share on other sites More sharing options...
