Why does the Kenwood KAC-M1824BT i have reject my phone when pairing. do i have to do a factory reset since it is a used unit

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.

hi rob there is no way u can pair ur keenwood to your phone. your still going to need a microphone so that your callers can hear you. i installed the same unit in my durango a year ago and had the same problem. the only thing to do is keep using the earpiece.

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 :)

from your sub connect one short piece of cable from + on one side to - on the other side using the same diameter cable as you are running to the sub from amp . this will leave you with + and - on opposite sides of speaker these will then run to the amp +to+ and - to- on the mono side of connetor which is one left + and one - right and the amp switched to bridged
