Kenwood KAC-6404

Kenwood KAC-6404: Great Value?

I purchased this product to use in my boat to push four 4" marine speakers. I have to say that I was somewhat disappointed after hearing the difference but without a subwoofer I probably can't blame it on this amp. I selected this unit based upon it's low price, size and low current draw. If I had to do it again, I might have gone with an amp that has the capability to add a sub unit. Overall, I'm ok with this product because it does allow me to get more volume without too much distortion but I was hoping for a more noticable improvement.

Good basic upgrade

Good amp for making the sound better for people IN your car. Not incredible amounts of power but it sounds good and gets the job done for just a basic upgrade. Got one stolen and I liked it enough to replace with same.

small amp big punch

This is a small amp so use it well if your gonna use it for front and back set up get 2 ohm speakers for the back this will get you more punch or I used it for my 4 front speakers which I also used 2 ohm speakers in my doors and 3.5 inch in the dash so it realy sounds great with the 7205 Kenwood in the back with the KAC 6993 PS speakers lots of power I also have hooked up the 9105 amp for my subs with are pushing 2 Pioneer dual coils 2 ohm subs in series and its the best system I have had all for under 1000 dollars

Subpar Amplifier

This is a very reasonably priced, albeit middle-of-the-road amp. I purchased it on the advice of C*****f****, but find that it does not do the job for my Polk speakers (I listen to '60's Stax, Exile-era Stones, '70's/'80's Punk). Very little kick, & does not allow for much adjustment (tweaking) of the sound. Overall, I am disappointed by this product, and wish I had spent a few more dollars for an amp w/more umph.

good amp,great price

I have this amp powering mb quart component set up . I only use 2 channels on this amp , and boy those speakers scream, this amp is a little big, but well worth it. It also has lots of features, letting you get optimal sound clarity out of everything you run off it. I would recommend this amp to anyone.

Great Amp

This amp is great, i recent pulled it out of my explorer because i sold it, and wanted to keep my sound equipment. This amp has a lot of good tuning features and is a great contributor to any sound system.
