Kicker zr240 amp sound shut off and on while driving.

    The ground wire is mounted to my fuel pump ground in the base of my trunk. If the ground was lose wouldn't the amp power light turn off?

    The protection light does not flash or come on. I have had the amp for 10 years now and that light would always turn on when it got hot.

    The crossover that is in it now it the SWX. I do not think this was the original crossover that it came with. I thought I had one go bad on me when I first bought the amp years ago so that was my first guess as to why it seems to shut off and on.

    sounds like a loose wire.

    But please check all of the following and re-post....

    Positive wire & post at battery tight?

    Main power wire Fuseholder Secure to wire @ battery?

    Ground for amplifier sanded & tight?

    Positive, Ground, and 12V turn on wire all secure at amplifier terminal?

    Any indicator lights (protection) on the amplifier coming on?

I doubt it is loose solder sure it is just a bad connction between that junk crossover and the even crappier amp. Try just cleaning the connection points with rubbing alcohol or something and see if that works...if not, try building up the flat male side of the connection with a tiny hint of solder and force it to connect...if that doesnt fix your problem...throw that POS away and buy a real amp!

Need to know if my equiptment can push another kicker

yes you can add another sub to your amp. hopefully it has another terminal to let you do so if not you can just use one and splice the wire to each woofer. and yes get a capacitor itll save your battery alternator ect... i waited to long and fryed my heated seats from my car power surging

I know i had a similar problem in my car, i ended up needing to do a battery relocation to the boot and putting a bigger battery in. Dont forget that just because the physical size is big doesnt mean it it has the amps so read the battery!

I have a Kicker 2500.1 monoblock amp. I am going to run 4 15 inch Kicker L5 subs to this one amp. What ohm subs do I need to purchase? Dual 2 ohm, or dual 4 ohm? Also, how would I wire these subs to pull a...

make sure that you get dual 2 ohm subs. to get a 1 ohm load, wire each sub in a series. that means the positive from one coil, connected to the negative of the opposite coil. then the other two leads will be your active speaker wires. that will give you a 4 ohm load for each sub. once all 4 are wired like this, you simply take all of the positive wires that you have left, and combine them at the amp. do the same with all of the negative wires. that will give you 1 ohm. just be extra careful to make sure every sub is wired exactly the same, otherwise your sound quality will be greatly reduced.
also, 2500 watts isnt as much power as these subs will take if wired together. it will still sound awesome, but I reccommend turning the level on your amp up just until you hear a bit of distortion, then back it off a hair. being slightly underpowered will cause you to have some distortion in your bass. playing distorted notes builds up alot of heat in the voice coils, and these subs are VERY sensitive to overheating.

Kicker zr240 amp

yup your problem is most likely the solder joints have vibrated loose. dont use it till you resolder all the solder joints on the mosfets and the bigger transistors on the board.

Sound shuts off, sub still works

That is a common problem with this radio, for it can not go to loud without going down in volume or shutting down.

At high volume sound shuts off, subs still work

You most likely have a shorted or damaged speaker, which is causing the internal amp chip to shut down (but does not affect the preamp outputs). A test you can do is to fade to one speaker at a time and turn it up to se if it shuts down. Repeat with each speaker until you find the one that causes the fault. Then replace it.
