What is the rms outpur of my kenwood KAC 848 amp

Try and match the rms output of the amp to the speaker , if the amp puts out 150 watts RMS make sure your speaker is at least 150 watts RMS.

The KAC-624 is a 40 watt x2 @ 4 ohm RMS amp. 55 watt x2 @ 2ohm. 110 watt x 1 Bridged I assume at 4 ohm. Manual does not specify. It can run 2 ohm in stereo mode but is unclear on mono impedance requirement. It can run 4 ohm mono at 110 watt but at 2 ohm?

is the amp 2 ohm stable? does the amp have enough watts to support the rms of the sub

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.

bigger the better my friend. Look at your Peak RMS output, and how long of wire you need. Then you could make the judgment call on how thick or what gauge you need. (2 involved factors power + distance). id say 10 gauge and you would be fine.

There is an Internal Fuse on Most of these Models that will blow from time to time. You might also check the Ground Connection. A loose Ground can cause the Same Problem. Please Rate My Response! Thanks!

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

Are you sure you have the speakers wired to present a safe load to the amp?

You have blown outputs , faulty channels. What kind of amp do u have and what were u running to it? Most likely a bad amp, u might need a new one.
