Amp Keeps blowin fuses

Aight, heres my problemz..

I have a Sony Xplod 1200 watt amp, its connected with an 8 gauge wire. But for some reason I keep poping the Fuse, the one on the line from the battery to the fuse in the engine (not on the sub). Anyone know why? Is the Gauge not large enough or what else?

If anybody knows please reply, im on my 6th fuse!!!

your amp could be ******* more amps than the fuse is rated for

that happens to me //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

What size fuse are you putting in there right now?

I would go to 4 gauge wire, it might not solve the problem, but 8 gauge is a little to thin for that much current.

Aight, I had a 5 amp fuse (Stupid me) I switched to a 30 amp fuse and well see how it works, I had it running for about an hour and so far i haven't poped one.

Thanks for the Fuse info, next I think ill bump up to a 4 gauge wire!

change your wire to 4 gauge your amp is pulling alot of current and your fuse are over heating that why there blowing on also what size ground are you using you my want to change it to 4gauge also (i had the same problem at one point in time and these changes helped me out.//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

i bought the same amp... i never got it to work... it blew 60 AMP line fuses like crazy.... your running a 30 amp fuse? are you speaking of the in line fuse that protects the power line. the line from the batt to the amp... or are you speaking of the fuse on the amp itself....

the amp itself has 40AMP fuses so the inline fuse should be at 80 AMPS.. and yea if i were you i might just go to a 4 gauge wire... i have 8 gauge and had a 1000 Watt amp pulling from it... and it was running 2 speakers 4 Ohms parallel bridged which pulls a 2 ohm load and it ran fine... until the day it suddenly popped out from a short circuit.. i drove a 14 hour road trip on that bugger and it never overheated once... but ithat amp was power efficient... it ran at 40Amps max. yours pulls 80 max... you need a 4 gauge.

ironslave I have no clue what you were getting at, but here is simple terms.

Match the inline fuse to the MAX amp/fuse rating on your amp. A 4guage wire kit is ideal for 1000+watts. Rule of thumb your power and ground should match in guage. If you go 4 guage power and 8 guage ground you will see problems. Bottom line upgrade to a 4 guage amp kit (walmart sells for like 25$) comes with ring terminals and all that jazz. If you really want to get into it you can go with a digital inline fuse and a circuit breaker.
