Doesn't turn on

make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

do you have the rem (remote turn on) connected to the remote turn on lead from your head unit? what make and model is your head unit>?

Yor best bet is to wire each one positive to neg to get 8ohms then pos-pos and neg-neg to get 2.66 ohms. Otherwise series parallel. If you wire them all pos-pos and neg-neg you will be running .66ohms and will most certainly fry your amp or it will overheat and shut down all the time

either bad ohm load or over heat if the ohs on the speaker wires to the amp are lower than specified use in the manual it will act funny cause it is pusing harder than its meant to and if it gets too hot either bad location or bad amp you can try turning the gain down a little until the amp stays on constantly at high volume

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.

i had this same prob. & i run 2 amps as well, cameto find out i had a neg. & positive touching , so check all ur wiring for tht amp..

You will probably need to use a Line Output Converter (LOC). They're available at virtually any shop that sells car audio.

Many times, the outputs of the OEM amplifier will have significant DC voltage on them. This could damage the input circuits on the kenwood amplifier.

Let me know if you have any other questions.

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:


As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

how big the amp dont forget those thing take lots of juice you need a big wire front battery to amp when the engine running it should be 13.8 to 14.5 volt if anything less than that battery wont get the charge up and check for good ground cheers and dont forget to rate this p.s any other question about our charging system or anything else dont hesitate im ear
