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.

Reduce the amount of boost or, better yet, turn off the bass boost. With your installation, overemphasis on the bass is causing the rattles and distortion

Can a kenwood KAC-6104D amp power 2 subs? what subs would go well with this amp?


dependent upon the wattage of both the amp and speakers in same olm configuration. Too much amp is a good thing, too little is a bad thing as it will burn up your speakers and amp

The subs aren't pushing out bass.


Hello crobins2,

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

Hope this helps.

Probems with my kenwood 7020 amp


The ground nearest "batt" connection is your main ground. The other "GND" is for grounding shielded RCA cables.

If the amp is being used to run subs alone:
  • Set the Bass Boost to 0.
  • Set the LPF Frequency to about 80.
  • Set the Input Sensitivity to 5 (the minimum).
  • Set the Filter to LPF.
If things sound fine at these settings, one at a time, slowly bump the Bass Boost and the Input Sensitivity up, checking the sound quality as you go.

Set your HPF and LPF on the headunit to match the crossover on the kenwood amp.

I have the same amp, it's really not difficult to figure out. Try these settings, For the AMP: Bass Boost: 0 Crossover: 150 Level: 1

Now just go into the menu for your head unit and make sure you set the crossovers to 150 or whatever option you have, just make sure they match.

Simple.

May i suggest removing the equilizer unless you can adjust the settings for each amp seperatly. The amps themselves will allow you to add bass boost and treble boost. I think the problem your having is trying to run to much bass through your system causing it to distort badly.
