for some reason, my car keeps popping fuse for my amp. i have no idea why, i tried to upgrade the fuse from a 50a to and 80a. the 80a lasted for a while then pop. so i wanted to go up to 100a. pop. has anyone ever had this problem. i have no idea, why. nothings touching that i can see wit my eye. i just really want to listen to my bass.

upping the fuse rating is a bad idea. there is a problem. stick with the OEM size fuse. you must have a short or something like that.

bad ground or something with the power.. I just recently moved my power from the battery to the fuse box under the hood, maybe try that???

Possibly there is an internal short in the amp. Where is the fuse? close to the amp, or at the power source? If you don't mind cutting the wire and placing another fuse at the amp, I would put a higher on at the power source (battery if that's where it is) and the recommended one at the amp. Which one blows is going to tell you where the short is. Also like c987long said ther may be a power issue (bad connection?) Lower voltage means higer amperage draw. If you have a multimeter check the volts at both ends to check for a voltage drop. With it off it shouldn't be any more than .1 volt at the worst.

Ok, the amp has 3(30 fuse) in it. My systems like this, battery the a lil fuse box and three inches from battery (80a) fuse is. Then wired to the amp. i believe the lil fuse box may have a short or something, cuz it blows the fuses there, not at the amp. if it was a short in the wire the amp would not come on after the fuse is in and radio is on. i"m planning to cut the lil fuse box and add something else.

It still blew the fuses with the key in my pocket. i thought , there will be no power if there no key in the whole. As i started to disconnect it and reconnect it, it started to spark. Blew the 100a fuse, i thought there no way i should a 100a fuse, im really screw.

Normally, if you have 3x30a fuses on your amp, use a 90a fuse at the source. Also, whenever you are connecting anything to the battery, disconnect the ground first.
Check the InLine Fuse Holder to see if it touches any metal parts in the engine bay, and check your power wire to see if there's any cuts in the envelope that could create a short circuit. Also make sure that everything is properly wired at the amp and that the negative cable from the amp is securely bolted to a paint-free area.

well after some thought last night . I left my house a littlle early today. So i pulled up the seat to check all lines. the ground looked good, but the power was cought on something. So I pulled it and seen a small cut and burnt threw the wire. So i taped it and i'm goin to hope for the best.
