Re: amp heating up
Here is the link for the user manual for your amp if you need it;
a poor ground connection can lower the voltage available to the amplifier by essentially adding a resistor in series with the amp. low voltages can often cause overheating in electronic components, but not always and unusual in amplifiers.
The poor ground connection itself would get hot, even to the point of fire, and a certain amount of heat is conducted along the wire into the amp terminal, unlikely to be enough to make the amp run hot without you noticing smoldering cable insulation.
What exactly do you mean by "not in a good spot"? - a ground connection is only in a bad spot if it is likely to get damaged, or not making a good connection all the way to the battery. - please explain more.
A poor ground could lead to low voltage, which could lead to component damage, which could cause the components to run warmer than normal and is probably not reversible, but usually relatively easily repaired.
Page 2 of the manual describes the protection function, which should activate if your amp is getting too hot - if it hasnt activated then most likely the temperature you are experiencing is normal. The protection will also cut in if the ground is bad.
Hope this helps :)

are you saying the unit wont turn on? if it heats up your ground and power connections are fine as it is completing the circuit. I would deff make sure the ground is as good as can be (sanded off paint and touching raw metal) and if you are using a really small guage wire for your amp that can cause a problem as well. BUT if its not turning on make sure the blue remote wire is correctly connected to both the amp and the head unit.
Sounds like a shorted speaker wire. Try disconnecting speaker from amp and see if protection light goes out- if so replace bad speaker wire. Only other issue i can think of from your short description is that you might have a bad ground going to amp or the remote power wire is bad. try running a new ground wire to a clean metallic spot on you cars chassis close to where the amp is located. Good ground = good clean sound
It's doing that cause it's trying to protect its self. There is either something shorting out or blown inside or the power/ground/remote wires could be shorting out going to it. Make sure that the power/ground/remote wires aren't touching any metal and that there are no breaks in the insulation. If it's not that and you're getting 12v on the power and know you have a good ground something has probably gone bad on the board. This can be caused by a multitude of reasons from faulty components to heat to trying to push to much power out of it.
Make sure your remote wire is hooked up in the right spot, also check your rca plugs and consider replacing them, check all fuses to make sure their not blown, a loose or not good ground wire or power supply wire will also cause this problem. If a power wire has a cut in it, that will also cause fuses to blow, as well as with a ground wire cut, ur amp will not be properly grounded.
Your over heating check and see if you can put in cooler spot also make sure u are getting good voltage through wires use a volt meter on pos and neg connectors at amp while radio is down and then when it is 3/4 volume should not drop more than.75 if is then go with bigger wires also if that does not work and amp is hot to touch check on installing fans
well, an inadequate ground source (paint between the ring terminal and the ground metal) or just not a good place on the chasis that is grounded. Or you have the amp wired at a low ohm load. the lower ohm load that you have your amp wired at the hotter and more current it will draw from your vehicle. this basically means you may be overworking your amp... If it's improperly wired from the subs to the amp you will certainly fry your amp. Also another reason your amp can get hot is if the amp is underpowering your subs a lot... this also is incuded in overworking your amp... usually it will cause a lot of headlight dimming and that kind of stuff... Also if you have a lot of voltage drop in the vehicle like down in the 11 volt range when the subs hit it will cause your amplifier to heat up a lot...
THIS IS AN EASY FIX. DISCONNECT THE POWER WIRE FROM BATTERY. REMOVE THE GROUND WIRE FROM THE CARS BODY. SAND ALL THE PAINT AWAY FROM THAT AREA. WIPE IT CLEAN WITH A DRY CLOTH AND HOOK THE GROUND BACK UP. THEN RECONNECT THE POWER WIRE AND THAT SHOULD FIX IT. IF NOT THEN TURN DOWN UR GAIN CAUSE THE AMP IS OVER HEATING
what type of terminal is on the amp. screw or slip on type?
The plastic does not carry any type of ground. If your ground wire was melted, that means you have a 'hot' wire shorting across the ground somehow causing a short. This causes excessive heat like an 'arc' welder.
You might want to check your power wire to make sure its not making any contact to ground. Make sure any foreign debris is not causing a 'bridge' between the 2 posts.
If your terminals (or place where you hook up power and ground wires) are in good shape, re-wire and turn on the unit.
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.
