[QUOTE="Evan Landrum, post: 8876596, member: 691501"] My setup is 4 Morel 69c, pioneer deh-4220bt, and kttp445u (I had the amp installed by a professional Alpine dealer). I've noticed something I NEED fixed. At a lower volume (15-20) the bass is very much present (It's set to be able to turn up to 42 without distortion/clipping). Once I turn it up to that, though, the bass hits really nice, but it only last for a minute or so. After that, the speakers sound quieter and the bass is there, just not as hard. What gives? Only thing I've noticed that, I'd imagine is an issue, (not saying this has anything to do with it) is that the ground from the amp is connected to the factory stereo ground. This amp requires 15+ fuse. My stereo is only 10. The amp doesn't appear extremely hot or anything (it's only ever warm). I ask on here as, with work, it'll be a bit before I can take it in again to have them check it out. They said on the phone it's something they'd have to look at. I'd appreciate any help! Thank you!
