12's cut off

**Tha Ghost** · 01-13-2011

I put a kicker 300 watt amp, with some quantum cozmic series 12's with tha stock radio, and they sound pretty good but they cut off, after a while of bumping the amp just turns off and like 30 seconds later tha bass just turns on.

sounds like the amp is going into protection

**Tha Ghost** · 01-13-2011

yes but i dont know y it does that.

**01PonGPGT** · 01-13-2011

thats why you dont buy kicker

thermal protect

amp being run at too low a nominal impedance or their is insufficient airflow over your amp.

basicly what matt (oh techincal almighty lol) is saying is...you amp is too small. it will push (play) your subs, but after playing for a certain amount of time at certain levels, it goes into protection aka shuts off to stop from burning up. and there's nothing wrong with kicker. get what you like but make sure you have enough power to push them at the volume u want to play them. (i would suggest some audio brands, but its really to each its own) so either turn the amp down (turn the gain down) or get a bigger amp

Model of your amp? If it's a two channel and you're running bridged then you're load is too low...as said stated already.

my amp can put out 1500 watts RMS as per turbo trav..............

yet i can still get it to hit thermal protect after 40 minutes of beating on the sub with consistant bass tracks in the dead of summer and i'm probably only running 400-800 RMS.

Sub can handle a 1 kW too.

Basically it needs some sort of cooling.

But i have a better solution, sell it

I don't know what you guys do...I haven't hit thermals yet

err...I take that back. My kenwood in highschool did in the heat of summer.

People don't have thought out installs?

that is why i think the amp is too small, its 300watts on two 12's (in the WINTER time), Ive had this happen many of times because i couldnt afford a bigger amp.

Um. Turn your gains down? The amp was designed to function within a certain performance envelope. Some how you're working it outside of that. I blame install and tuning. Howeer, if it's an older amp it could be something else....
