SOURCE: Protection light on Kicker ZX700.5

Considering you just bought it, the amplifier itself is probably not the issue. Small chance it is, but we'll go with that a last resort. Have you hooked it up without any speakers connected? Does the light still come on? Describe all the connections you have made to amp (what came from where, and what terminals it is connected to.)

SOURCE: AMP shuts off

your problem could be in the fact that you are trying to overdrive the amp. sony will not carry a 1 ohm stable load and if your speaker are 4 ohm speakers wired in series then you cant drive the bass your looking for. try using soundstream tarantula amp or new hifonics block mono class d amp with about 1000 watts rms. what kicker subs do you have? that will also make the difference in amp choice. im running tarantula on 4 polk momo 4 ohm 12's and has broke my back glass in my jeep twice one time was for a show. oh well let me know. happy boom boom. i'll be glad to help

SOURCE: subs dont work when base is up high

Sounds like the amps needing more current available to it-You should have 4 gauge power coming off the battery going into a distribution block from there a 4 gauge to a 1 farad capacitor off the block -4 gauge to the ground for the capacitor -and two + leads from the block to your amps-you would do well with 6 gauge there.- That is to ensure that you have plenty of power on tap when needed and not trying to draw it off your charging system on heavy current demands.Make sure that your grounds are well placed and solidly connected. As for putting 600+watts on a pair of 8z......i hope that they are the CVR or the L5 / L7 series to take that much power,I've seen it done and the ones i heard sounded badass(L7 series)-but that was at the stereo shop so they had they stuff on HITTN status up in there. If your running the "cvr" or the "comp" series you might be throwing too much power on them -might want to step up your subs to a set of 12s just to get more air moving in there- good luck

SOURCE: my amp goes into protection mode at high volume

Hi does the amp return to normal operation once the volume is lowered? If so it sounds like the amp is seeing too low an ohmage due to the way the subs are wired & they are drawing too much current so the protection circuit intervenes to prevent damage.The minimum ohmage this amp must be operated at is 2 ohms so if you are running at 1 ohm this will cause the problem you are experiencing.
Cheers, acbva.

Kicker dx 500.1 keeps ruining my subs


if your sub isnt blown, i'd follow your own idea and look for a bad wiring connections, also what kind of head unit do u have? check the settings on ur head unit to see if there is a seperate setting for your amp/subs if it does have one, make sure it is set properly

if it does not have a setting like above, check the rca cable from the radio to tthe amp, and make sure that the rca cable is plugged in to " input instead of the output

I just bought a cvr kicker 10' sub, hooked it up in my car replaceing a polk audio sub. The kicker keeps blowing my fuse. i have checked the wireing. i have an 800watt sony xplode amp. Please help


i am assuming that you bought this sub used? their could be a problem with your voice coil. the voice coil moves the cone of the speaker in and out. the problem with the voice coil is that it has become lose and is doping the impedance of the sub. A lose voice coil can be cause by over powering the sub. this problem is not fix able.

Hi, I currently have the following Kicker Amp's.\r...


it depends, sometimes if your speaker is wired, if you have two dual 2 ohm subs and wire them in series ( +to+ -to- ) then they will wire down to .5 ohms, in which your amp is not stable other possible problems may occur if you wire these amps together to power one or two subs

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.
