BenzBass Posted June 21, 2012 Report Share Posted June 21, 2012 So I have a Hifonics HFi2000d and I realized that my amp has no fuses, so basically I'm wondering what's the deal basically. I've got a fuse on the power wire from my battery to my cap(I know, I know, I just need to get the funds for the big three) but I don't know what to do. Should I leave it be, or should I add another fuse from the cap to the amp? I hope all this makes sense. Quote Link to comment Share on other sites More sharing options...
t-money Posted June 21, 2012 Report Share Posted June 21, 2012 its prolly internally fused.

kickass audio Posted June 21, 2012 Report Share Posted June 21, 2012 Id get a fuse going between the cap and amp if it was my setup. And if you upgrade that cap to a battery down the line you want to put a fuse just before the cap so both sides of that main power wire from front to back are fused. Always fuse before the amp to be safe. Even though if you do draw too much power you can pop the fuse under the hood however that cap will still have some stored power although it wont be much it is still something and can spark a fire if the amp itself shorted out. Be safe and put a fuse just before the amp and know your car is safe. Also do NOT exceed the power capability of the wire for the fuse size.

t-money Posted June 21, 2012 Report Share Posted June 21, 2012 its prolly internally fused. Is that necessarily a good or bad thing? depends. i no my AQ2200d is internal. sucks if u ever blow it cuz i think you would have to send it in to have it fixed but if you blow the fuse on the amp something prolly isnt right in the first place Quote 2002 ford focus hatch pioneer DEH-P8400bh infinity kappa 6.5 components front and rear XS Power D1200 Shuriken BT-100 audioque 120.4 2 15 inch audioque HDC3 D2 2 audioque 2200d big 3 mechman 220a alt with external regulator 479-418-3056 Link to comment Share on other sites More sharing options...

My wiring kit I used DB Link "1600 watt" has an 80 amp fuse I believe, how do they get the 1600 watts limit with the 80 amp fuse? Like how do they come up with that number?

kickass audio Posted June 21, 2012 Report Share Posted June 21, 2012 Usually for every 1000 watts your amp puts out you will need 100 amps of power for it. What gauge is that wire? It sounds like it may be like 4ga or something. Also some manufacturers go way below the current capability of their wire size due to the wire not being of high quality and not being able to handle the true current that said wire gauge is supposed to carry.

Lbox88 Posted June 21, 2012 Report Share Posted June 21, 2012 (edited) wow to some of the above posts........ Anywhoo If have have/look in the manual for that amp, it'll most likely tell you that you need an external fuse right before the amp and will tell you how large of a fuse you need. EDIT: Sonic says a 200A fuse, here's the manual, go to about page 6 http://www.maxxsonic...er%20Manual.pdf Edited June 21, 2012 by Lbox88 Quote UBL | Build Log Link to comment Share on other sites More sharing options...

Chris Hammer Posted June 21, 2012 Report Share Posted June 21, 2012 You need to get better power wire to start off with. some dblink 4gauge CCA wont cut it. 80 amp fuse at 14.4 volts gets you a maximum of 1150-1160 watts before it blows. You are starving your amp.... Go on Knukoncepts website. Get some Ogauge. Kolossus flex if OFC its better but the KCA 0gauge can still supply more than enough for your 2000watts. You need to get 2 fuse holders...2 200amp fuses and ditch the capcitor. You should probably think about getting a second battery as I'm pretty sure you will still have voltage drop with the big3 and stock alt/battery.
