Don't complain man! you bonused!! Run the wire, and get a distribution block to split and fuse the wires going to the amps.

For a power wire you can never go to big, unless you're running a 15 ft. span of 000 gauge for 200 watts.

lol cuz before i purchaed the amp everyone here said get 4 guage and that 2guage would be over kill so i bought the 4 guage and got a 2 guage. I KNOW IM one LUCKY son of a gun these 2 guage kits are like 120CDN i got for 30 CDN LOL. i have 17FT of wire i just checked this sites power wire rating chart.i WILL NEVER EVER need to buy a new power wire lol this thing is good up to 1600RMS. HAHAHAHHAHAH im so happy. Alpine Guy DO you mean a FUSED DISRO BLOCK or just the 80AMP FUSE at less than 2ft from battery? i already got 2 distro blocks.

Yea he meant a fused distro block. but goin on what you have said i dont see the need, that is if your only runing a single amp. Where as if ur running multi amps i agree with that idea.

well i plan on running the the 2 guage to a distro block then shooting out 2 4 guages to the amps then another 2 4guage ground wires to a distro block then the 2guage to the ground. i was only planning on using the fuse that came with the kit and place it liek 1 ft away from battery its a 80AMP fuse run this wire to the block then have to two 4guages to amps. i didnt know i needed a fused distro block do i really need to get one i already bought a distro tho

I dont believe it is absolutly nessessary to be using a fused distro block. It all just comes down to how much money you want to spend, and how much power your system uses. I have fused distro blocks in mi install, its not a very big one, but it saves me having to buy them in the future when i upgrade. Also i just wanted to have them in their for a lil added safety, mainly bekoz its my first install and i took all the precausions... ------------- ~* Cheer Nat *~

best to fuse closest to your battery. after that you dont have to worry about anything. If you get a spike it should blow the fuse by the battery first

jeffchilcott everyone else here is saying that I NEED in addition to the fust at the battery that i need to fuse the wires before the amps beacuse im going to be running the 2 guage to a dISTRO block then two 4s to each amp. th eone amp is a phoenix gold tantrum 300.2 it will be doing 320RMS @ 4ohms and the other will be doing 80*2RMS (160RMS total @ 4ohms). they saying that i need to FUSE the 4 guages before going to amp. i have the 80amp fuse at the battery. since i dont have a distro block now can i run the 2 GUAGE directly to either my 160RMS amp or my 320RMS amp temporaily till i get the distro block the 2 guage will be fused at the batter by 80AMPS. thanks let me know.

You do not need a fused distrobution block, a normal one will work. I like fused ones so i can pull the fuse for the one amp and disconect that single amp without going under the hood or anything. Technically all you need is teh fuse under the hood, , but some at the split for the amps can never hurt. It is important to have a fused distro block however if you have a 250 amp fuse at the battery, , then you split it down to 4 awg, , you will need to fuse the 4 awg wire to prevent them from over current and melting. But in your situation, since your only useing a 80 amp fuse at the batt, you will be fine. ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

If you are going to go big with that "extra 2 guage" (lucky)... Then i'd fuse it with a 250-300 Amp fuse. You got overkill, so finish it with overkill. Then it will all be good.

ok cuz my "system" which really isnt a system will contain this after the 2 guage install 1 Phoenix Gold Tantrum 300.2 (321RMS*1 @4 ohms thats the MAX the amp can do continously at 14.39V) this will be powering my JL 12W3v2 D2 in a 2.0 ft^3 ported box tuned to about 32.5HZ or so. 1 ALpine V12 MRV-T320 it will do 80*2 RMS @ 4ohms it will power my INFINTY KAPPA PERFECTS 6.1's Tomorrow the weather is looking good since i dont have 4guage wire lying around i wanan run the 2 guage directly to the alpine amp and use the sub iwth that amp till i can get some 4 guage is this safe? Once i get anotehr distro block and some 4 guage wiring. I will Run the 2guage to distro run 2 4guages to each amp then run the 2 - (groun ) wires from amp to a distro block then run the 2 guage to ground ? this is all i plan to do thanks. im not in a hazard zone by doing this correcct? uthinkuknoaudio: what do you exactly mean by having a 250AMp fuse i will never ever be usign more than that my car cant even put out that much lol. also i dont excatly know what you mean by YOU got overkill finish it off with over kill?
