MTX has the hookup diagram here: http://www.mtx.com/caraudio/products/manualsQuickInstall/amps/RTP251D_InstallSheet.pdf If you have the original wiring harness, the ground wire is normally black. The amplifier case or chassis is ground connnected on amps I've seen as well.

How can u bypass the protect on a kicker 500.1 amp??


Theres not really a way to bypass that. You have wires touching that shouldn't be touching, bad ground (id take your ground and clean any paint or dirt around it or find totally diff ground), or connector somewhere. Fix that and you should be good to go.

I have a alpine mrp-m500 for about two years no problems at all. but one day it stops producing sound. i check all fuse on the whole system. is the a protect mode? and how do get it out of it?


If you have checked all the fuses.
Trace your ground wire that goes to the frame. It may be possible your ground is no longer grounded properly. You may just need to unhook the fuse from the battery, Unhook the ground wire from the chassis and restrip, put on a new connector, chisel off the paint around where the amp was grounded to and tighten it back down. Hook back up your fuse to the battery and check and see if it removes the protect light.
Also check to make sure your RCA cables aren't bad. If the RCA cables ground it'll put the amp into protect mode too. Basically just switch out the RCA cables for a good pair.
If the remote wire on the amp is touching the ground, it'll throw the protect light too. That's pretty much the extent, unless the amp has a short inside it.

Hope this helps!

I plug in rockwood detanator VII and it goes to protections mode


Generally if an amp goes straight into protection, the amp is not grounded well enough. Either you should find a new location to ground the amp to or unhook the power wire from the battery, remove the ground wire from the chassis of your vehicle. Strip the paint from the chassis, since it doesn't conduct electricity, and remove any corrosion or copper shielding from the ground connector. reground to a solid metal location Can be grounded to the brace behind the back seat or to the seat belt bolt for best results.
An amp draws a lot of power, there it needs to be grounded well.
Hook back up your power wire to the battery and see if your issue is resolved.

My kenwood amp wont turn on


What kind of "Clips" did you put on? They may be causing too much resistance and preventing the amp from getting the current it needs. Double-check with a voltmeter that you are getting at least 12 volts at the amp power connections and make sure your ground lead is as short as possible and connected to solid metal of the vehicle's chassis.

Mine is actually a q4000 4 channel amp


First of all, you MUST HOOK UP YOUR GROUND WIRE FIRST. You may have damaged it if you hooked your power and trigger wire first and then the ground wire. Unhook EVERYTHING except the hot wire, ground wire and trigger wire. If you still can't get the unit to come on then it is time for a trip to the repair shop. Good luck.
