I've got 2 12" Kenwood KFC-W3011 subs, with a Kenwood KAC-X10D Amp. The first 5 or 6 months of having the subs, they were bumping nice and loud, just what I wanted. Lately, I'll put my subs at the same settings to bump them, and they will go for like 30 seconds, and then get really quiet (just a much smaller more muffled bass sound), as if the amp turned off, or toned the subs down, or something like that. So I brought it to Custom Sounds and they messed around with a couple controls for like 5 minutes which seemed to fix it, so after bumping for a couple of minutes after leaving, they did the exact same thing, and went quiet.
Does this mean my amp needs to be tuned, or that my fuse is blown, or that my subs are blown?..or possibly my amp isn't strong enough for these 12's.

Update..
I just went and took the fuse out to check it out, and then put it in a few minutes later with the car off. When I tried putting it in the first time, there was a spark, and then after trying again, it went in with no problem...weird thing is...my subs sound awesome now and stay on. Did I REALLY just blow the fuse, or do worse damage than I think, or is there any electrical/mechanical reason why this could have fixed it?

Sounds like the amp is going into protection mode. You'll know if you blew the subs they sound like sh!t as soon as you put any bass through them. With that amp you should be pushing 300watts per sub, which should be fine. I've own several pair of those subs, pushing 350 per. I kept selling the pair when I needed money but I also kept going back to these subs.

check and recheck your grounds. I had bad ground once and the voltage kept fluctuating, the bass would hit hard then muffle then when the bass stop (ie. just lyrics in the song) then the next bass hit it was ok but got muffled on the next bass beat, it was annoying as hell until I checked the ground points.

subs dont always sound bad when they are blown. IF the voice coil is starting to go bad it may not sound bad at first. What happens is it causes a ground that feeds back to the amplifier. That could cause the amp to shut down and go into protection. Sounds like you just had a fuse that was not working for you. doesnt sound like it was a blown fuse but maybe loose and when the amp heated up it loosened up. Ive been selling, installing, and competing for over 15 years Ive seen some weird stuff along the way.
Not for nothing but I work for a 12 volt distributor in colorado currently. Anybody want some good pricing on electronics PM me.
