I agree with the person who said that the ohmage is lower than the 4 ohm, but also check to see if your voltage drops lower than 10 volts it used to happen to mine and the fuse kept blowing

If it only does it when bridged, the ohm load may be too low.

Is it blowing the fuse on the amp or the one near the battery?

My kenwood KAC-7204--- the wiring is hooked up right, I just got a 2000 watt max sub 1000 watt rms, i was running the amp in bridge mode and it ran for 1 day than it turned off. I checked it and the fuse...


when i was running my sub off bridge mode this kept happening to me. I ended up just running two subs and for some reason the fuse stopped blowing. i think there is something wrong with these amps.

I a looking to qire two 10 inch kicker comps what is the best way to get sound out of this set up in a sealed box and kac 7252 amp 1000 watt


check the ohms on the subs if its single 2 ohm make sure you dont bridge it avoid 1 ohm unless the amp is class d duel 2s make 4 or 1 depending on if you series on paralel them duel 4s make 2 ohms or 8 you want to make a duel 4ohm 2ohm and put one on each chanel email me for better exp.

Just woundering if i could bridge one sub to front and one to rear the subs are kenwood w3514 dvc subs the amp is kenwood kac-x501f


Hello bigmac208,

Yes, that would be the best connection for both the subs and the amp.

I'd wire the sub voice coils in series since the amp will not be stable at 2 ohms when the channels are bridged. The power will be somewhere between 100-200 watts RMS to each sub. While it's not pavement pounding, it should provide pretty good bass, especially if you tweak the crossover and boost settings for best bass response.

Hope this helps.

Want to bridge my subs I have a kenwood kac-719


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 :)

Kenwood kac-7202 wirng 4 subs


look at the Z [impedance] specs for the amp. Look at the Z for the speakers. You may eventually have to wire them in a series-parallel config or risk blowing your output transistors.

Due to the utilization of so many drivers, your power demands are limited. The more drivers you utilize, the more volume loss. Bass response requires a lot of power (W) in which to drive.

Do not worry about paper or polyprop/carbonate structures... focus on your impedance issue or risk frying the output transistors in the long run [thermal runaway].

Bridging


What type of subs are they? Single or dual voice coils? 2 ohm or 4 ohm?

Power of amplifier


If the KAC-7252 is to be bridged, the operation mode switch on the top of the amp is set to mono. When switched to Mono, the signal from the left channel input only is used. Bridging creates 4 times as much power so the KAC-7252 delivers 170 Watts per channel so that 340 watts total so that value 340 is multiplied by 4 and that gives you 1360 watts of power. so it will drive them.

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.
