I have a kicker zx750.1 hooked up to a comp vx 12. all wiring is per kicker recommendations. it will initially turn on fine and power the sub, but will randomly go into protection mode, sometimes coming back on after a minute or so, and sometimes not at all.was sent to kicker for inspection and they said there was no problem with it. i checked all wiring except for behind the deck. could it possibly be a bare wire touching metal somewhere in the dash?
If the amp is powering on the sub and playing and then turns in to protect mode it could be the amp is getting hot and its kicking into protect so you wont fry the amp
Check again the wires behind the deck , if still doing the same thing , then check how do you have the speakers connected , in SERIES or PARALLEL ???? HOW MANY SPEAKERS ARE CONNECTED ???? The thing is your amp could be detecting a low OHMS IMPENDANCE than required by manufacture, and its protecting your amp output chips , hope this helps

When an amplifier like the Kicker IQ 1000.5 goes into protect mode due to overvoltage, it is a safety feature to prevent damage to the amplifier or connected speakers. Here are some steps you can take to troubleshoot the issue:
Check the power source: Make sure the amplifier is getting the correct voltage from the power source. The Kicker IQ 1000.5 amplifier requires a 12-volt power supply with a recommended amperage of 80A.
Check the wiring: Check the wiring between the amplifier and the power source, as well as the wiring to the speakers. Make sure there are no loose connections or damaged wires.
Check the amplifier settings: Make sure the amplifier settings are correctly configured, including gain, crossover, and subsonic filter. Ensure that the amplifier is not being overdriven by the source unit.
Let the amplifier cool down: Turn off the amplifier and allow it to cool down if it has been running for an extended period.
If none of these steps resolve the issue, it is best to consult a professional installer or contact Kicker technical support for further assistance.
Power up the ampwith no speaker connected. If it goes into protect mode, the amp has been damaged.
If it is OK, check your user manual for wiring instructions, loading etc.
Do not allow the speaker wires to touch the car chassis/metalwork!
Sounds like your wiring is giving you the wrong impedance,Check crutch field advisors website for sub box construction and detailed wiring instructions.
That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.
Protection LED on, no output? Amplifi er is very hot = thermal protection is engaged. Test for proper
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow around
the amplifi er. Amplifi er shuts down only while vehicle is running = voltage protection circuitry is engaged.
Voltage to the amplifi er is not within the 10–16 volt operating range. Have the vehicle’s charging and electrical
system inspected. Amplifi er will only play at low volume levels = short circuit protection is engaged. Check
for speaker wires shorted to each other or to the vehicle chassis. Check for damaged speakers or speaker(s)
operating below the minimum recommended impedance.
No or low output? Check the balance control on source unit Check the RCA (or speaker input) and
speaker output connections.
It when into protection mode either because something shorted, or it was over loaded, or over heated.
Disconnect the power for 5 minutes then hook it back up.
If after doing this it still remains in protected mode, there could be a more serious problem.
If it comes out of protection, and it goes back to protected mode a lot, then you have you ohm load wired too low. The amplifier cannot handle that low of an ohm load.
rewire the subs-each sub you want in series=8 ohms per sub-then at the amp wire the two 8 ohm subs in parallel which brings the ohms back down to 4 ohms which is optimal for the amp and it shouldnt shut down on you any more-try that-good luck
It sounds like you may have the load impedance too low.
How many voice coils per woofer?
How many ohms is each coil?
If you have DVC woofers, are the coils for each woofer wired in series or parallel?
Are the speakers wired in series or parallel.
Let me know if you need me to clarify anything.
