a little bit of fuse rating advice please?

Recommended Posts

i dont want to second guess myself so im trying to get another opinion on a good estimation of what size fuses i need to get. what im running is a kinetik 1800 in the hood and a kinetik 1800 in the back of tundra (ext. cab with seats taking out) with 2 runs of 0g. i have a 180 amp alt under the hood complete with the big 3 all in 0g. I have two ANL inline holders, one in the wire right after the + terminal on the kinetik in the hood and then one on the wire in between the alt and + terminal on the kinetik under the hood. What size should i get for those two (they should both be the same right)? are there any other places that would be ideal to place an inline fuse. then i have a distru. block with a 0g in and out of it is a 0g to my american bass XD3000 and a 4g runnning to my RF punch 400-2. The fuses in the block are mini ANLs. what size should i get for the AB amp and what size for the RF amp. This is going to be my first big install including thousands of dollars worth of audio equipment that i have worked hard for to save up for a while and i really dont want to be blowing anything. I'd like to do it right the first time with no mistakes or uh-ohs. Please give me some advice audio experts!

350a for the under the hood blocks.

You really have the wrong kind of block for in the back though. Mini ANL or KF fuses only go up to 150a. 150a is a huge bottleneck on 1/0awg wire.

alright... can you give me some recommendations on a block for in the back. that was the only one i could find that knukonceptz sell but im open to anything. If you know one with a 0g in with 0g & 4g out that uses regular ANL fuses let me know please. Especially im looking for one with the digital voltage readout would be nice. moneys not really a huge factor, just give me a recommendation please and what size the two fuses should be on the AB and RF amp outs. thanks

ok i think i decided what im going to do... from the pos. terminal in the back ill send a 0g out to the AB and then a 4g line to the RF. Then ill just put an inline fuse holder on each of those lines but im still question what size on each line. Should i go with ANL on the AB and a mini ANL on the RF or ANLs on both of them? And ill go ahead and do the 350 on the lines under the hood.

can some one please give me an opinion on what fuse size for the RF amp and what size for the AB amp... and im guessing 350 on the two under the hood sound good. thanks

Lets go back to basic car audio 101 on this.

The fuse isn't ment to protect the amp. The Fuse is ment to protect the wire. So now you have two options, Fuse to the maximum amperage the wire can handle, or fuse just below that point.

1/0awg can take 400-350a depending on length.

4awg can take 100-150a depending on length.

I fuse to the maximum of the wiring usually. In your case, I'd fuse the 1/0 line at 250-300. For the 4awg line, I'd fuse at 100-150.
