[QUOTE="LAYLOW, post: 2409330, member: 572266"] Ok... here's the background on my setup: I have a fuse link off my pos from the battery (plastic screw together type) and a fuse block (three fuses) in the trunk with my cap, subs, 2 amps, and crossover (all existing for about 1.5 - 2 years). I have two square 12" Solos in the box and a Punch Power 1000 amp going to them. I have a Punch 800 going to the mids/highs. I have blown the fuse in the front (fuse link) a few times over the lifetime of having the system and just replaced it no problem. I've also blown a fuse or two in the back fuse block and just replace with no issues. I put 80A fuses in all of the locations I've mentioned. Here's the current issue: I got a new Alpine HU to replace my Premier (Pioneer) HU. I installed it and everything was working perfectly for about a week. I was driving and suddenly everything went completely silent, but the HU stayed powered and the display continued. From past experience, I knew I had blown the front fuse-link fuse. I replaced with another 80A fuse and it blew again as soon as I turned the HU back on (after turning it off and the car off to replace the fuse). I thought maybe I had a dud fuse and put another in there. Everything was cool for a few more minutes of driving and then the bass fuse in the block in the back blew (1 of the 3 is bass). I replaced that fuse (as well as the other 2 just for kicks) with all 80A fuses. I noticed that when I was replacing all of these fuses, they were FIRE hot when i pulled them out, which I don't think is normal. I pulled the bass fuse out completely and just rode the rest of my trip with mids/highs. Two days later, I put the bass fuse back in and noticed that the bass was not hitting as hard. The front fuse blew again and when I went to check it out, the plastic threads had literally melted to the end cap of the fuse link on one side. All connections to the battery are solid and no corrosion shows at all. One of the subs was not hitting when I looked at the back while the music was on, and the other was barely hitting. For the time being, I replaced the fuse link in the front and took the bass fuse out and am just using mids/highs now. This has been fine for 5 days so it seems something related to the bass fuse being in there is causing the issue... any help would be appreciated in figuring this thing out. Thanks.... [/QUOTE]
