The amp will reset every time it's turned off. The red light flashing, instead of staying constant is a warning that one of the protection circuits are activated. If the amp is bridged wrong, it can do this. If the load impedance is too low, it can also do this... don't trust the speaker, it it says 4-ohm, it may actually be 3.8-ohm, which could cause a problem if two speakers are wired in parallel. If it's not getting enough power, it will turn off briefly, but will turn back on after a second. A capacitor is not necessary with this, just use 4 gauge cable and have a good battery... make sure the ground is good, that one is commonly ignored.

SOURCE: Kenwood Audio Amp KA-5040R - remains in standby

Hi, Lost sole, i HOPE YOU FIND IT

Minwhile, when it works to know if you have a cold solder joint, hit the unit on the top or buttom to see if it stop working, mostlikly it will,
To fix this you must unplug the unit open the bottom cover, and solder joint that look broken off, moslity on the output stage or power supply.
What I think happening is when the unit heat's up the joint expand and doesn't do contact no more.

Another problem that this may be is a bad power supply, cap's, this can be check by freezing them to see if the unit starts again.

This is little trick of the trade, I hope this help

On the top of the amplifier are 4 controls. The first one is labeled as "input sensitivity". That is the adjustment you need to make. It would need to be set at around mid way between minimum and maximum.

One way for you to set it perfectly for your speaker would be to have it set first at about 1/4th of maximum, and then with the volume of the head unit turned all the way up with some heavy bass playing start to turn the input sensitivity up very slowly until you hear a small amount of distortion or rattling from the sub woofer. At that point you would back it down just a touch until there is no distortion or rattling from the speaker. This would have your amplifier set at a point where it is not pushing the speaker too hard but you would be getting the most from it.

Remember that any time you hear distortion, you are either pushing the speaker too hard or the amp too hard. The distortion is caused by clipping, which is not a good thing. If there is no clipping from the amp, and no abnormal sound from the speaker, you have it set properly to get the most from both the amp and the speaker and you are then minimizing the chance of damaging either the amp or the speaker.

Very wise decision on your part to want to use your equipment properly and not expect more than it is actually capable of. Many people just push their equipment to the max and then complain about how it broke down on them. If you follow my instructions you should be able to keep your sub woofer and amplifier in good working condition for as long as possible. It is no guarantee that it will never break down on you, but you will at least give it it's best chance for longevity.

SOURCE: how to hook up kenwood kac-7204 1000watt amp

I found the manual & have pasted the url here for you. some things to keep in mind. according to the instruction manual this unit is rated @ 500W, not 1000W. Also to maximize the output you should use 2ohm speakers for stereo applications. Also make sure if you need to extend the power wire, use 10 gauge copper & make sure it's connected to the car battery thru a 60 amp fuse. Also make sure the ground is attached to a clean metal frame or body part by using a bolt & nut not merely a screw. Good luck. If you need additional assistance let me know.

Ihave a keenwood kac 7252 amp that is running two mtx thunder 4500 12`s but amp fuse keeps blowing at higher volume why?


1.-check proper heat sink, or dissipation.
2.- check speaker impedance. Must match between amp and speakers.
3.-low power line on the house may cause low efficience work on the amp, overheat, and finally fuse protection.
4.- finally, check speaker wires. Thin cable overheat amp too.

How to bridge a kenwood kac-9105d


Are you referring to something like this, using two different amps? It is a mono amp, meaning there's one amp in the box.
"KAC-9105D also has a Dual Mono Drive connection that allows you to strap two KAC-9105D amps together to power a single subwoofer."Quoted fromhttp://www.kenwoodusa.com/Car_Entertainment/Amplifiers/KAC-9105D

Here's a link to a page out of the Yamaha Sound Reinforcement book. the top shows a stereo amp (1 box, two different amps inside) hooked up to drive two different speakers, which is known as 'stereo' mode.It then shows the two amps hooked to the opposite sides of the same speaker, which is known as 'bridge' mode.http://books57.net/ampOuts.gif

Any help?

I have a kenwood kac-9152d running a 10 inch rockford fosgate power t1 and the amp keeps going into protect but i have a smaller kenwood kac-8102d running on another t1 and i have no issues with it why...


either the wiring your running is short circuting,or the amp is shot, or the subwoofer is shot, try hooking the same speaker up to the other amp. along with the other speaker to the other amp, see if the same thing happens.

Red Light


that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad

Cant get but one side to work


This amp (kenwood  819)  was designed for use with a sub-woofer, hence the single chanel. It will however power up 4 speakers in mono, and if they are capable of handling the amps.while robbing you of the benefits of stereo as well as left, right and fade control.Good luck...
If you still want it connected. You should purchase an amp installation kit, and review the topics and videos at this web site. www.installdr.com

Good luck...

Amp Turns on... then off


unplug all speakers and see if it still into protect .If unit powers up normally without speakers , then hook up a temporary speaker directly to speaker out to see if you have output.If it works .Then check speaker cables and speakers for shorts.Also make sure you have good ground and main power and standy are present.

Amp won't turn on don't know if amp is fried


Very possible that you have a blown power supply in the amp. If you are running a mono amp then there is a very good chance that you have loaded your amp with too low of a speaker impedence and fried the power supply and maybe the output section of the audio area. Hope this helps.
