Hey guy's, I have a small two channel kenwood amplifier that I would like to use to power my 5" subwoofer. It's a kenwood kac 33 non bridgeable amp. My question is how can I bridge this amp and use it to power my subwoofer. I know you have to invert one of the channels but I don't know how this is done. If someone knows, can you please post instructions on how to do it and if needed, any parts required to make a non bridgeable amp bridgeable.

Thanks!

If you bridge a non bridgeable amp...won't you be presenting it with a ohm load that's lower than what it's capable of handling?
I'd say get a small mono block amp...or a small bridgeable amp.Either one will definitely last longer than an amp that is forced to do something it's not designed to do.

Call me crazy, but I'd hook it up using 1 of the chanels and see how it sounds. You don't need much power on the 5 inch sub. if the amp was not made to be bridged, I'd say they probably had a reason ....

You will need a rather complex circuit that, though I can design for you, will be overkill and probably cost an exorbitant amount of money for the cause. I say use one of the channels, or find a decent mono amp. A 5" sub will probably only handle about 50W RMS at most.

not gonna happen. in order for an amp to be bridgable, it has to be designed to share a common ground/negative whatever you wanna call it.
if the 2 channels are isolated from each other - trying to bridge is just gonna wreck the amp.

best you could do is run a dual voice coil sub and run each side to it...tim

FYI, i had a friend do this in high school and the amp lasted approx. a week-bad idea.

Either get a new dual voice coil subwoofer or get another 5" sub.
To make a circuit to bridge the amp will cost too much.
You could always sell it on Ebay and buy either a bridgable one or a mono amp.

Hooking up one channel is also a bad idea. First you would only get that channel's sound and second, If you left the other channel open, it could unbalance the amp and eventually kill it. (Depends on how the output is configured)

DO NOT ATTEMPT THIS

bridging a nonbridgable amp can cause a short. If your lucky you just ruin the amp if you have my kinda luck you fry some major parts of the sound system or even worse gets realy hot with fire potential.

You don't. That's why it's NON bridgeable...

Thanks for the input everybody. Looks like I need to get another amp...the search continues!
