Red Triangle light off?

My kenwood Kac-9105D 2 channel 1800watt amp was working fine the night befor. but i took my system out of my car to clean my car up real good and to put new back seats in. Well after i was done doing that. and hooked everything back up and turned my car on to make sure it worked. the red triangle light that is usually on. came on real quick then straight off leaving the blue line light under it on still. Would this be a wiring issue? i was told it was. but i couldnt find the problem. PLEASE HELP!

    @hoyzee1 I Checked the fuses on the amp. there fine. and to even make sure it wasnt the fuses. i replaced them with brand new ones (30s) i think it is my remote wire leading to my CD player. cause when i have it just hooked up to the remote conection in the amp, it does nothing. but i jumped it from the remote to power and the redlight comes on for about 3 seconds then as soon as the music starts playing it turns off leaving the blue line light on though. but now i unhooked it and redone the wiring on the amp. and the remote wire didnt work again so i jumped it. now the red light comes on real quick and goes back off again leaving the blue line light on.

    @Larry Tezekjian it cant be the subs cause i just bought the subwoofers.. ALSO the amp doesnt move arround non. i had it mounted to the box. i have also unplugged the subwoofers to see if anything changed. and it does the same thing. (AMP IS ABOUT A MONTH OLD)

I have the same amp in my car, If it is only a month old there is a internal problem with it, It should stay on when you used a jumper wire, I installed car audio for over 40 years before i retired, End was allso Am a certified electronic (Tech) PS,One thing it is not a 2 channel amp, people mistake it for a 2 channel amp because of the for speaker terminals on them, It is a mono (Bloc) Amp ,End where people go wrong on wireing them up is buy , Having each sub hooh up seperately to it, Instead of use just one of the negative end positive terminal on it , .I no the instruction for the wireing on it are confuseing, That can cause it to shot down. Allso if you have dual voice coil subs end there not wired up properly will cause it to shot down,

Circuit City ? I'll keep that opinion to myself.
If all is properly hooked up, Check the ground wire for the amp.
Give it a tug where it is connected to the car chassis, NOT the amp,
if it moves or comes loose thats easy to fix, scrape the paint off the grounding point use a high quality ring terminal and a oversize screw with a star locknut. Also check the wiring in the box.
Subs and boxes are quite heavy. And if it's banging around, I hope you have it in a trunk, they are very lethal projectiles in a hatchback should you have a accident.
My second thought is that you may have dislocated a component , solder joint, or cracked the PC board,
When in doubt see a installer. Good luck Sumthin

SOURCE: power amp wont power up

Check the fuses-should be a pair of 30 amps on the side. use a paper clip and jump power from the power+ to the remote+ and see if that lights it up-if it does than your remote lead isnt giving it juice-

SOURCE: Kenwood KAC-8401 light goes from blue to red when turned on

Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

A ground wire may have come loose or your subs may be blown.

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 from

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.

Any help?

First of all, how are your subs wired to the amp. Make sure your amp is not bridged or you'll fry it, it only has one channel. If that doesn't work you probably already fried your amp.

How to wire kenwood amp to kicker cvr 12"

How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.

A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.

Have fun
