i have a kenwood amp that blow the fuse if the amp level is turned up to 3/4 and the music plays for 5 mins. if i turn the gain down to 1/4 the music plays all day with no problem. think its the internals of the amp. any help.

first off, is this to power speakers or subs? Also, how do you have them wired?

Post the specs of the subs and how you have them wired--it sounds like you're running less than a 2ohm load.

sounds like you are clipping the amp...possibly low voltage. The amp is regulated so so when voltage goes down the current goes up and you are blowing fuses.
Why don't you CORRECTLY set your gain and you will have no problems.

they are wired on two phoniex digital 12's dvc. they are wired to see 2ohms and they are 2 chan amp stereo. the amp don't get hot .

ok what impedance are the subs???
what model amp is this???
you are being too general...can't find out whats the problem if we are in the dark

The gain is not a volume knob. Read up and set it correctly. If this doesn't fix the problem, which I'm assuming it will, get back to us.

"They are wired to see 2ohms and they are 2 chan amp stereo"
First, have you checked the resistance with a meter, or are you just guessing. A simple wiring mistake - which we've all made - can make the difference between 4ohms and 1/2ohm.
Second, check the specs on your amp. 2ohms @ 2channels might be too low. Consider bridging your amp or changing the wiring to a higher load.
