you mean two fuses in parallel? that is how two 15A would be similar to one 30A.

AGU fuses are unreliable.

why no MAXI fuses? they are great!

You'd be surprised how many people in meca run agu fuses and have success. Maxi fuses used to be used.....until a few years ago. I'm pretty sure they caught on that they don't blow too easy. I personally like to use anl fuses. I had my run with mini anl's, pretty much a fail.

I'm not saying AGU fuses can't work, just that they aren't a reliable design. The solder holding the fuse element can fail before the element does.

Ah, gotcha. Well...I haven't messed with every kind of fuse. But in this situation (trying to cram as much power through a fuse for at least 3-5 seconds), which kind of fuse would you look more into?

After hours of research, Crutchfield has the fuses I need for .99/ea with free shipping so thats the best deal coupled with super quick shipping. I'm looking into marine/boat fuse gangs to run a bunch of small fuses in line to get as much surface area for the current to travel over. A competitor at the last show I went to was burping 8 dc 5ks on 99 3a atc fuses.

99 3 amp fuses? That's crazy. It might have looked cool, but kind of pointless, lol. That'll put you in street or mod 5, so in that case, run 10 300 amp fuses or whatever and be done with it, lol.

well the more you can spread it out the longer it will last.

Try using the cheaper AGU fuses , most guys here are using Audiopipe, Install Bay , XXX, etc. and have pretty good luck with them, and running 99 fuses would be pointless because it should put you in a S-M 5 class where fuses aren't required anyway

In 2 class where you can run a max of two fuses, try running a large ANL (300amp) in series into a smaller fuse (60 amp AGU/ANL) only the last fuse will count as long as they are wired in series, start by using the fewest fuses as possible, the more fuses you run the more resistance you will have.

Well I'm not saying I would run that many fuses, but I'd like to be able to adapt the same concept. The guy was in radical x1 doing 164s and in db5 park and pound he did 133.

I was playing around on the meter today for maybe an 30-45mins or so and it was real hot out...I pull out of the parking lot I was in and the bass cuts out. At first I thought I put the amp into thermal protect because it was pretty hot to the touch....turns out the solder came loose on my fuse at the battery up front. Only took a few hours of taking the amp out and giving it to an electrical engineer to test the circuits, only to find out the power wires had no power. The fuses looked perfect too, that why I didn't check them beyond a visual inspection. Macro mode on my Epic ftw. This thing takes excellent detailed shots up close.

5 class is unlimited on fuse count, lower classes are allowed the total # of fuses to equal their class #, so long as that rating value with cone area does not exceed the specific class limits. I like AGUs, and I have definately seen cheaper fuses do better. I saw an audiopipe 300a fuse have the filament turn red hot and smoke, but not pop

that is an awesome close-up pic. nice camera!

ive always wanted to put 100a in a 70a case for an agu....
