Jaloosk Posted April 23, 2012 Report Share Posted April 23, 2012 add up all the fuses in your amps, then buy an ANL that's bigger. For instance, I have one amp with 80A worth of fuses in it, another with 60A worth of fuses and a third processor with 25A fuse. 80+60+25 = 165A so I bought a 200A fuse (next size bigger). The main fuse is to protect against a short in the event of a crash (or bad install). "Cheap, good or fast. You can only pick two out of three." "Have money? Love story! No money? I'm sorry."

justinschmidt Posted April 23, 2012 Author Report Share Posted April 23, 2012 My amps have external fuses. 100amp was included with each but I hear that's a little underrated.

Kranny Posted April 23, 2012 Report Share Posted April 23, 2012 Second battery > distribution block? I realize the cap isn't helping me much but I keep it for two main reasons, it shows instant voltage and it's an easy distribution point currently. Once I stabilize the voltage I will spend the time/money on actual distribution blocks and trash the cap. Thanks for the advice. at this point the cap is literally just a power drainer. sell it for $40 and use the money to get a $20 volt meter to install in your line of sight on the dash and a $20 distro block. In my eyes, yes. No point in using a distro block when you just run 0 gauge from front batt to rear batt and wire the amps up to the rear batt Link to comment Share on other sites More sharing options...
Jaloosk Posted April 23, 2012 Report Share Posted April 23, 2012 My amps have external fuses. 100amp was included with each but I hear that's a little underrated. The you need to look in your amplifier manual, check for max amperage draw and fuse each amp for that. Then add up your max potential draw and put your main fuse just above that number.

justinschmidt Posted April 23, 2012 Author Report Share Posted April 23, 2012 I actually could not locate that info in the manual. I looked twice maybe I'm missing something.

andrew018018 Posted April 23, 2012 Report Share Posted April 23, 2012 Its not really rocket science .. you have 2*100A = 200A ... then add how much your mids'n'highs amp fuse rating is, a 250 amp fuse will probably be the right one for you system My System (in VW golf/Rabbit mk2) (1) Hifonics Brutus 2010D @ 1ohm (1) Hifonics Zeus 440 Mids'nhighs (3) JBL W10Gti subs (2) JBL GTO838 (2) JBL GTO936 (1) run of 3/0 Gauge ofc (1) Ac Delco120ah 850cca battery (front) (1) Ac Delco 45ah 330cca battery (rear) (1)Sony Gt630ui hu 34hz tuning Link to comment Share on other sites More sharing options...

So I would need to find the max amperage draw which I have not been successful at thus far.

Kranny Posted April 23, 2012 Report Share Posted April 23, 2012 Your manual said the 1500 needs a 100a fuse? Are you sure you're looking at the right one in the manual? Link to comment Share on other sites More sharing options...
justinschmidt Posted April 23, 2012 Author Report Share Posted April 23, 2012 No the amplifier actually came with a 100 amp barrel style inline fuse with fuse holder. But 1500 watts and 100 amps doesn't really add up to me.

Kranny Posted April 23, 2012 Report Share Posted April 23, 2012 Weird. That amp is inefficient as fuck so it has to draw more than 100a. I'd just use 150 per amp. Link to comment Share on other sites More sharing options...
