Amp protection problem

I think I've done every thing, I've change the wiring from 8ga to 4ga, I put a cap on the line to stablize the power supply but the amp will still shut down after a while. I'm running one mtx 7500 12" at 4ohms the recommend power is 400 watts, with this amp I'm pushing 500 watts to it would that cause a short in the speaker? the amp is not that warm when it goes into protection.

I run one sub on my Kenwood Amp also. It does over heat also. My conclusion is that we are both trying to push that one sub too hard and the amp is having to work really hard to make that sub do what we are asking. Also, not having enough power or a good ground will cause it to over heat. I am going to go with the voice coils are heating up though.

I have a 300 Watt dual amplifier connected to one 12" kicker dvc sub at 2 ohms. Every time the volume is turned up the protect light turns on. I had 2 of these kickers wired to a Rockford amp a week...

Then you have found your problem. It's internal on the amp. Protection circuitry issue. Have it Benched at a shop with the same impedance you are running it at. If it benches ok, check your ground, it should be no longer than 18" and go directly to the floor frame, not a seat bolt. You should also be running at least
4ga power as well. Hope this helps.

I am purchasing a kicker solo x 12inch and installing it into a crown vic. can i hook it up like a regular sub power from batt to cap and amp or do i need to have an extra power source like another battery...

4Ga wire should be plenty for your application.
If you're concerned - run (2) lengths of 4Ga - its cheaper than 0.
A battery only extends the playing time of your system with the vehicle off.
Your car runs off alternator power - and it is recommended you upgrade the alternator to a High capacity one to properly supply voltage to your amplifier.
A capacitor is a cheap bandaid that will prolong the life of your stock alternator - but eventually - the alternator will die from the lage demands placed on it.
Put the battery and cap money toward a High Output alternator.

I dont Know what guage of wires to use with my Amp

8ga will be fine with the amp listed, but if you plan on upgrading in the future, then go ahead, and buy the bigger wire. 4ga +. See at the time of purchase there is only about $20 difference between 8ga, and 4ga kits, but if you go with the smaller wire for now, and then upgrade later on, you end up paying double for yopur wire, and double for your install (if you arent doing it yourself).

WHY DOES MY AMP CONTINUE TO BLOW ITS FUSE ..I HAVE A 4GA AMP KIT ON IT ......IS THAT TO BIG ..I DONT EVEN HAVE ANY SUBS HOOKED TO IT ..VISONIK V107SX

go with an 8GA wire and see what that does for you because the battery is sending power to an amp but the amp cannot transfer all of that power anywhere without speakers being ran to it if you think 8GA is to small then try running a fuse in with your 4GA

Replaced the fan on my HA 3500 bass amp, but it does not want to spin. Need to know where to check for voltage (for the fan) to see if there is another issue. Amp plays great, except for heating up after a short time (due to no fan).
