The first thing you must do is to confirm that you have voltage at the amp. Just because the fuses look good, that doesn't mean you're getting power to the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

SOURCE: To bridge a Kenwood KAC-9102D

Hello laurogleal,

The Kenwood KAC-9102D is a mono amp. There is no bridging. Having two sets of terminals is just a more convenient way of connecting two subwoofers. The amp is stable down to 2 ohms impedance, so it is safe to run 2 4 ohm loads in parallel.

Hope this helps.

from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

this is a kenwood correct? this is a simple wiring all after market amps are the exact wiring there will be three posts one that probably says 12 volt, another that says either REM, or REMOTE, and another that says Ground
go and buy a amp wiring kit, it will have everything, the 12 volt post it attached to the positive of your battery post, the REM or Remote wire is attached to the blue wire with the white stripe on the back of your deck, NOTE! if you have a stock radio you need to get the wiring diagram for your wire harness if you need this let me know ill help you get it, and the ground goes within 6 inches away from the amp attached to bare metal on the body of your car. grind off the paint of possible, make it a good solid ground.
