Fusion 2500d Cutting Out

[Donks 10+ year member]

I got a Fusion 2500d today. it was already hooked up w/capacitor and fuse holders...etc

I hooked it up to my 15's @ 1ohm. and its works fine when the volume is super low but as i turn the volume up and the bass really starts to hit, i hear a clicking noise inside the amp like a cutoff then backon type of noise. IDK i have a good ground and 1/0ga wire. idk what it is but its urking me. My Directed 1100d works fine on them, just wanted to upgrade a little.

did you check the voltage at the amp while playing?could be to low causeing it to cut out.

Should i try to hook power wire and ground str8 to the amp and bypass the capacitor?

how do you do that?? i have a DMM reader.

with that amp at 1 ohm, it can draw around 140, 150 amps or so. i would recomend a 2nd battery and at least a 120a alt to run that amp daily at 1 ohm safely.

is it 1 ohm stable? and bypass the cap, are any of the connections corroded?

set your dmm to dc volts, turn your system up to where the prob is and then check the voltage at the + and - of the amp.

It has 2 external 80amp fuses wired w/ the capacitor.

yes, with good electrical they will run daily at .5

that amp needs just one 200a fuse, and yes ditch the cap. how big is your alt. and what type of battery do you have

ok i bypassed the capacitor and the volts sitting around 14.3v. still cutting out though. I have a 80amp under the hood btw..

thats the voltage when the amp cuts out? or just with the car running?

you need to see what the voltage is when it cuts out. most cars will charge around 14.3ish volts, but but the amp will draw current and cause the voltage to dip when it is playing music. running that much power on stock electrical isnt a great idea.

i agree with every one so far. man u gota see what your voltage is at when that thing cuts out. Do u have any extra battery's

It sits at aroun 14.3v with car on. When I turn up volume it cuts out it drops to around 11.3v....

Im starting to think either the problem is either

1. The Amp is way to powerful for my Stock electrical. escpecially since i got an oldschool caprice

2. I need at least a 200amp fuse. Not just the 80amp fuse under the hood.

3. I havent done Big 3.

4. I got 1/0ga power wire....and 4gauge ground wire(this shouldnt be a problem though because it works on my Directed 1100d fine)

5. The battery under my hood is small as heck....
