No power to amp

I have professional installed power. Ground wire is perfect, power wire perfect, and the remote wire also sufficent. But the amp light is blank, no red for protection or green for good either. I have a fan placed on top of the amp to keep from overheating. It worked good for 3 days and now i cant get it to work. The day it shutdown I could smell electricity from the amp area. The fan works good and my speakers are brand new. Whats wrong with my amp?

Do you have an inline fuse on the live wire?

Is there also a fuse that you can get to on the amplifier?

Try changing the fuse's to see if thats the problem,

How to hook up the wiring on the crunch 520.5 need to know the gage for power

Hello,

I would go with some good 8 gauge. More than that for this amp would be overkill and a waste. Many people thing thicker wire is better but that is not the case. To thick of wire to the power feed can draw to much power and send the amp into protect mode. Also to thick of wire with an insufficient amount of power can actual hamper the amps true abilities.
Use stranded copper wire not solid copper wire for the best results of conductivity.
Make sure to run a 50 amp fuse inline with the power wire right off the battery. Amps surge and it is far easier to replace a $1 fuse than components inside your amp.
Your ground is best served running to a bolt in the floorboard. Using the same size, style and quality as your power wire is recommended.
Your remote wire will connect to the remote wire running from the back of your deck. The remote wire enables your amp to shut off when your deck is shut off. A simple 16 gauge stranded copper wire will suffice for the remote wire.
I recommend hooking the speakers up using one speaker per channel. I don't bridge amps really. If you want more power then buy a bigger amp.
The AV cords will go from your deck to your amp right to right and left to left.
That's the way to wire your amp.

Regards, Tony

Kenwood eXcelon radio problem I have 2 subs in my civic that work perfectly fine but i recently tried to add another amp to run my front door speakers seperately. I spliced the remote wire between the two...

Cut the remote wire from the radio.
install a relay in line
the relay will have 4 or 5 terminals
connect terminal 87 to battery power and fuse it at 3amps
connect terminal 86 to the remote output from the head unit
connect terminal 85 to ground
connect terminal 30 to your amp turn on wires
this allows the turn on load to run thru the relay and not directly off the radio remote output

Kenwood KAC-729S keeps blowing fuses. Checked all cables, re-ran power, remote, and ground. All good, still blows them at power-up.

Hello opey_69a,

Here are the troubleshooting steps for fuses blowing.
1) Remove all wiring except ground, power and remote and see if the amp powers up without blowing the fuses. If it does, the problem is in the input cables or speaker wiring.
2) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current - check.
3) A shorted or grounded RCA cable may cause the fuses to blow - check.
4) If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier is probably defective, most likely shorted output MOSFET's. In this case the amp needs professional repair or replacement.

Hope this helps.

Amp flashes red light only, no other power seems to work on amp

Hello markrich78,

First determine if it is the amp or the wiring that is causing the problem.

Disconnect all wiring except ground, power and remote turn-on and see if the amp powers up properly. If it doesn't, the amp itself is defective and needs professional repair or replacement. If the amp powers up OK with just ground, power and remote turn-on connected, check all of your other wiring for shorts and grounds, or reconnect them one at a time.

Hope this helps.

Sony amp has no power

There should be 3 wires running to the amp. +12v, ground and remote. ensure the remote is connect to the remote of the player or preamp. if the remote aint connected there will be no power on the amp.. if yor radio or player dont have a remote wire, connect the remote wire directly to the battery +12 to test it. If it powers on, then you can run the wire to a spst switch somewhere in the car and from the switch to the amp.

Check the fuese on the amp..
