Cant get but one side to work

You have the ohm load at 1 your amp i

you blew the output Ic's (amps one or more ) you can fix this by replacing the output IC's

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?

OK ! FIRST THINGS FIRST. DID U TEST THE AMP FIST. BEFORE U STARTED INSTALLING RCA CABLES,AND REMOTE WIRES. LETS DO THAT FIRST.GRAB YOUR AMP.SET IT ON YOU WORK BENCH ,TABLE,OR CHAIR.THEN GET (2)PIEACES OF #10 OR #12 WIRE W/1 OF THE WIRES HAVING A 20AMP FUSEABLE LINK ON IT.NOW THE WIRE W/THE FUSEABLE LINK ON IT.CONN THE REMOTE(REM) AND THE 12v + ON THE AMP AND HOOK THEM BOTH TOGETHER ON 1 SIDE OF THAT FUSEABLE LINK WIRE. AND THE OTHER WIRE HOOK IT UP THE - GROUND SIDE OF THE AMP .NOW PICK UP YOUR AMP OPEN UP YOUR HOOD.MAKING SURE THAT NO WIRES OR THE AMP IS TOUCHING THE + 12V OF THE BATTERY. NOW CONN YOUR GROUND TO GROUND AND THE FUSEABLE LINK ON THE +12v SIDE OF THE BATTERY.NOW THE AMP SHOULD HAVE CAME ON. LOOK 4 A SOLID RED LIGHT OR ANY SIGNS OF A SOLID LIGHT THAT HAD CAME ON.

leave power connections hooked up disconnect rca and speaker wires if they still blow more than likely problem with amp

genrally kenwood amps are power hungry amps so after playing for a while if it doesnt get the amount of amperage to make it work it will shut down cus you car cant charge the battery long enough for the use of that amp so my idea is try a farad capacitor and see if that helps good luck .......tk

HI DUDE EVERY REMOTE WIRE THEY HAVE FUSE NEAR THE BACK OF PLAYER TRY TO CHANGE IT .... R...TRY UNPLUG UR AMP .. AND ..FIX IT BACK

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

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.

May i suggest removing the equilizer unless you can adjust the settings for each amp seperatly. The amps themselves will allow you to add bass boost and treble boost. I think the problem your having is trying to run to much bass through your system causing it to distort badly.
