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?

Re: goes into protection mode for no reason
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

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.
check the fuse on the power wire (+) not the ground wire .. i had a kicker 1500.1 on 2 l7 15\'s and when the bass would hit hard the fuse would vibrate and cause the amp to go into safe mode.. after re wireing the whole truck i then found out it was the 150amp fuse holder
try hooking up only the power ground and remote see what happens if protection light is on then u have a problem with amp if it goes off then hook up rca if still off then hook up speaker wire if it turns on then u have a prob with speakers
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.
usualy means there is a problem with the speakers, they may be wired wrong, short in the wires or the voice coil in the speakers themselves. best way to trouble shoot is to power the amp with no speakers hooked to it, if it only goes ito protect with the speakers hooked to it, the the problem is with the speakers, not the amp.
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.
