Blowing fuses hello i was wondering if yo cold tell me why my 500 watt kicker amplifier keep blownig fuse

Send it back to maker for repair.

CX400.1 Mono Amplifier - KICKER

https://www.kicker.com > CXA4001-400-Watt-Mono-C...

Using efficient Class-D power, the CXA400.1 features a variable bass boost with KickEQ™, giving you as much as a 6dB of extra bump with a simple turn of the ..

need to know the ohms on the amplifiers then might can tell you best solution for system

open the amp up an see if u see anyhting burned on the inside next to ur fuse holder

disconnect the amp and then put the fuse in.if it blows,there is a pinched wire causing a short.
Also,big amplifiers like that have to be wired battery direct.
the surge current at boot up can pull 100 amps for 10 millisec.

Hello grabert205,

You do not say if the fuse blows immediately upon powering up or while the amplifier is operating. If it blows immediately, I'd check the power and ground.

If it is blowing the fuse while operating, I'd try a 30A and see if it holds. At maximum output of 100 watts times 4, the amplifier needs about 31 amps of current at 12.8V. So driving it hard could certainly blow a 25A fuse.

Hope this helps.

A easy way to tell how many watts an amp has is to look at the fuses on the amp itself eg. if it has one 10 amp fuse its probably a 100 watt amp, or say a 30 amp fuse would be around 300 watts. Most amps have more than one, so just add up the fuses and times it by 100.

Hello desperate2le,

Watts delivered is a function of the voltage times the current. If the amp was 100 percent efficient, it would need 33 amps at 12V for 400 watts. At 14.4V, it would only need 28 amps. Of course, amplifiers are NOT 100 percent efficient, only about 50-60 percent in many cases, but somewhat higher for monoblocks, maybe 80-90 percent. So you're looking at a fuse in the 60-80A range. In the absense of a specific fuse size from the manufacturer, I'd start the primary fuse at a 60A and if the amp blows it on power up/immediately/frequently, move up to an 80A.

All of the Rockford-Fosgate 2-channel bridgeables I've ever seen show using the left positive (+) and the right negative (-) for bridging. But if it's not shown right on the amp, I'd call or email RF for the correct connection. The new amps do show it.

Hope this helps.

12In Kicker CVRs
are Dual Voice Coil, and You can run each voice coil around 200 Watts RMS

So each sub will have a 400 Watt RMS and 800 Watts peak.

Now since you have 2, Your total will be 800 Watts RMS and 1600 Watts Peak.

I would get really any amp that sits at around 800-1000 Watts RMS.

These are kicker but they are low end so i wouldnt push them to the extreme.

1000-1200 Watts RMS Max and but keep the Gain down on the amp. They will hit no doubt but i wouldnt push these subs or you will be disapointed in the long run.

I would get a Fosgate or MTX amp.

You can get any amp really but find something right around 1000 Watts RMS and it will push those well.

You can go mono block or a 2 channel, just depends on how you want to wire them.

Be careful though. If your running them bridged right now with your mono block, do not run them parallel bridged on a 1000w RMS Amp, you will blow them so fast lol

(RMS = Root Mean Square. Or in other words is the continuous wattage being sent from the amplifier to the subwoffers)

first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ

Check your power cable, for bad connections.
Make sure voltage dont drop below 10.8v.
