i have an alpine plv-7 sub. It's been working great the past few months but recently i havnt been able to turn the volume as high as i used to. i would normal turn up to 25/40 to make it bump real good. But now i can go only up to 15/40 until the bass starts cutting out. I took it to a car audio place and tehy said the amp is overheating because of the summer time weather now. I find this hard to believe because why would it start happening just now after a few months of use?

and i dont know what to do because the amp is in the sub. I'm thinking something jsut might be plan wrong with the amp. idk im going to try and put a fan up to the ports of the sub and see if that helps it.

 

this is a known problem that has to do with the internal amp within the plv series. this is why they are no longer making it.

 

hmmm this isn't good. Did they do any or sort of recall on them? i fear i maybe "____ outta luck". i guess i'll call alpine and see what they can do...i don't even think its under warranty since i just bought this car that came with the sub.
