What fuse for cable from battery to Sundown SAE-1200D

[8adk1d 0]

The amp has 5x30amp fuses, so what type of cables and fuse should i use....I'm thinking 2 gauge cable from batt to distribution block and 4 gauge from block to amp

what fuses should i use?....the dude at the local stereo shop said the amp will not actually pull 150amps and said i would only need a 120amp block and i think it had 2 60amp fuses in parallel or something like that IDK and what should i use near the batt, the same?

You will want at least 150 amp fuse for that amp. That is the smallest I would recommend. Besides, you should be fusing the cable, not the amp because the fuses in the amp will protect the amp. I think the biggest fuse you want to run with 2 gauge is a 200 amp fuse and 4 gauge is 120-150.

Ok what I'm trying to say is what fuse should i use on the cable near the battery and what fuse rating distribution block should i use?

do you have any other amps?

id use a 200 amp by the battery and 150 amp for the d-block

Nope just going to run the 1 sundown amp with 1 sub @1ohm

Damn 200amp, jesus thats alot lol

You should see the 300 amp fuse on my 1/0 that goes to my SAX-100.4

if its just gonna be the sundown, id just do the 150.

All the fuses on the wiring are there to protect the wiring and the size should be determined based on the size of the wire, NOT on the size of the fuses on the amplifier.

Running 1/0 from the battery to a distribution block is what I would do. Then from the distribution block to the amp, the biggest gauge that fits in the amp terminal. If the amp accepts 1/0, I would only use a fuse next to the battery. 200-300A fusing is ok for 1/0. If the amp doesn't accept 1/0, you could use only one next to the batt and for added safety one smaller fuse right after the distro block.

Ok thanks for the input, good information...think I'll use 2 gauge wire and 160amp fuse or something 150 min....so, if I'm running 2gauge to dist block from batt and say 4 gauge to amp from the block, what size distribution block should i use? 120amp, 150 ect. does it matter if the blocks made up of 2 fuses that equal the total amount eg. 2x 80amps = 160amp total? thanks for any input, greatly appreciated!!!

Sorry "thefordmccord" what you said makes sense now, at the time I was confused () on what you were saying!

why not just run the 2ga all the way to the back and just trim it down so it fits in the amps terminals...the distro would be added resistance, and extra money for nothing

Yeah thats sounds like another option, I do want to see my voltages though

[hiloracerboy84 0]

so you're looking into a digital voltage display distro block? if so, you wont see it when you're playing...just run straight wire, and get a stinger volt meter or something up front. my opinion

[8adk1d 0]

Ok thanks for the help everyone I have a rough idea on what I'm going to do.....

Battery--------2 gauge wire (with at least 150amp fuse, I'll try and get 160-180amp fuse)--------Digital Distro block (150amp)-------2 gauge wire (or 4 gauge if can handle tad more than 150a)--------Amp, sound right?

would use 4 gauge on that last bit of wire but I dont like the idea of 150amps being the max that should be run through 4 gauge wire, I want a bit of headroom...so what do you reackon.... safe

amperage rating is also a function of wire length. length=resistance=bigger wire required. if that 4ga run is short, then it wont matter

Yes true true, I was looking before at the12v.com about cable lenghts and amps and wattages and stuff...

would it be ok if the 4 gauge wire was 19.5 Inches long, is that short enough?
