I didn't change the fuse, my dad said that would be a bad idea. Originally I had 2- 10" JBLs hooked up to this ARC Audio 4100SE, it was
bridged on one channel, I think thats the correct term. The wire was of very thin gauge. The setup worked well for 2 years, then my subs stopped working. I figured they were blown, they weren't. I disconnected the subs and amp, didn't use it for 8 months. So I wanted to upgrade to a single sub, link included below. I bought 12 gauge wire and hooked the sub up to the amp, and re-wired the amp to exactly how they set it up originally. I took a picture and kept it, so I'd know what went where when the time came. Amp has power, but again, sub wouldn't turn on. Turns out the inline fuse was blown. They threw a new fuse in, worked for about half a mile, and it turned off. Went back, they put an upgraded fuse holder on with the box housing the 80amp fuse. Worked fine. Then stopped.. Pulled the fuse and inspected it, wasn't blown so I put it back in. Again, worked fine. But whenever I would play music via bluetooth on my phone, sub wouldn't work.. I'd go to a cd, and it worked, stopped.. Now it won't turn on at all. The sub itself has one hook up per cable (positive and negative) - nothing else. I had the stereo place check the wiring, and they said it was all proper.
