My Kenwood 800watt amplifier

Hi, I have a Kenwood 800watt Amplifier....The problem is whenever it isn't bridged, it works fine...When I bridge the amp to get a louder bass and more watts to my subs, the amp will work okay for a couple of minutes, then kick off...it will remain off for anywhere between 5 seconds and a couple of minutes then it will turn back on...The fan is working properly on it and is always running...But the amp does get hot when it's bridged..Does anyone know the problem here or a possible solution?? is there a protectional fuse or something built into the amp???

Sounds like you have overloaded your amp. When you bridge you MUST make sure that you still have the proper speaker load. One 4 ohm speaker on one channel is fine, but when you bridge that same 4 ohm speaker, it gives you a 2 ohm load on each of the two channels that are now bridged. If you made the mistake of wiring two 4 ohm speakers in parallel (plus to plus and minus to minus) then when you bridge you will be driving a one ohm load on each channel. This is very close to a dead short. Stop using your amp at once until you get your speaker load correct. This will damage your amp and it will cause you to have to go to a repair shop to fix it. DO NOT RUN YOUR AMP ANYMORE UNTIL YOU FIX THIS. Good luck.

I have an alpine mrv-f307 4/3/2 channel. I have it hooked up to 2 12in Kenwood subs. Right now standard 2 channel each sub having their own. I heard doing a series hook up and bridging the subs to the amp ...

Bridging an amplifier refers to combining the power of two channels to run one speaker at higher power. If it is wired correctly, your amplifier is running with 4 channels bridged into 2 speakers now.

I need an appropriate speaker for my kenwood amplifier kac-5202

This amp is stable down to 4 ohms bridged at 120 Watts or 2 ohms stereo at 60 Watts X 2. If you are going with the bridged mono hookup just make sure the impedance of your subwoofer is no less than 4 ohms. A good rule of thumb is to be at least double of what your amps rated output power is. So if your amp can put out 120 Watts into 4 ohms then get at least a 240 watt subwoofer.

Do not exceed the rated load for your amp, you will damage it. Here is the datasheet for your amplifier

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.

Subwoofers

This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.

Is it not bridgable

This amp isn't bridgeable. It's a mono amp (only one channel). You need two independent channels to bridge. Some mono amps are bridgeable if you have two identical amps but I don't think Kenwood recommends that with this amp.

Wiring my subs to my alpine mrv-1000

did you read your instruction manual. does it says "it could be bridged to other amp"?. you can't make a bridge to amplifier that is not bridgeable. bridging an amp is a way which it is made through transistor type ampilfier by bridging more transistor inside and more voltage is required for bridging.
I don't know if we could do to an IC type amplifier. ask an experts about bridging IC types how to bridge maybe they know how.
and if you had an successful bridging, you may have a problem through your speakers, they may hit hard but you will experience some errors through your speakers and easy to worn.

Amp Problems

You are probably presenting too low an impedance load to the amplifier. In bridged mode the amp must be connected to a minimum 4-ohm load. If your subwoofer is a dual voice coil type with 4-ohm voice coils, you cannot wire the voice coils in parallel and connect it to the bridged amplifier. If you have a sub with dual 2-ohm voice coils, you can wire the voice coils in series and connect it to the amplifier in bridged mode. To connect voice coils in series: Connect a wire from the negative terminal of one coil to the positive terminal on the other coil. Connect the unused positive and negative terminals to the amplifier's output.
