Our take on the Kenwood KGC-4042A

Kenwood

Add the compact Kenwood KGC-4042A 5-band equalizer to your car stereo and see the difference an EQ can make — noticeably improved sound for your entire system.

The KGC-4042A offers three sets of RCA preamp outputs. Two full range sets are controlled by a fader to provide dual-amp balancing, even with a head unit that has only one pair of pre-outs. The fader's also ideal for dialing in just the right amount of rear-fill.

The third set is a low-pass subwoofer output with level control. Whenever this sub output is in use, the EQ engages high-pass crossovers on the front and rear channels. That's like having a free electronic crossover packaged with your equalizer — a pretty sweet deal!

Important Note: This unit has no built-in amplifier — must be used in conjunction with one or more external amplifiers.

Details:
  • two sets of full-range outputs with high-pass filter that engages when subwoofer output is in use.
  • subwoofer output has adjustable level control (up to +10 dB).
  • adjustable subwoofer crossover range (30-150 Hz)
  • dual illumination.
  • signal-to-noise ratio 100 dB
  • THD 0.01%
  • 3-1/2"W x 1"H x 5-3/4"D
  • 1-year warranty

Kenwood KGC-4042A

Written By All2skitzd, Dallas Tx on Tuesday, March 15, 2011
 
I first installed this EQ because the amp I stuck in to replace one that had a
meltdown didnt have bass controls one it (old school kenwood). Now iv replaced
my whole system besides this EQ. Adds a 100Hz Crossover on your front and
back speakers when using the sub output. Had to cut the back out of the pocket on
my dashkit on my 2001 cavalier but the hight is perfect and it sets back some to
prevent accidental adjustments.

oldie but goodie

Written By Ray, VA Beach , VA on Wednesday, February 04, 2009
Crutchfield Customer Review (What's this?)
 
Well, i have to say this the the best EQ ever for me, i was shocked they still made this one, i needed a replacement after having my original for so long .over 10 years as best i can remember anyways, but it is perfect for great sound. just would recommend it to anyone who needs a good EQ. Kenwood has always been a favorite of mine since i was a teen, and it still is, Thanks im happy again./ (just for the record the old EQ didnt die. it got wet or it would still be jamming! so it lasts and lasts long as you shut your sun roof ! hehe)

Great Unit

Written By John, California on Saturday, January 31, 2009
Crutchfield Customer Review (What's this?)
 
This is a great little unit. Back in 1977 I had a 7 band equalizer from Alpine and the digital time delay. I sold both when I bought another new car. I had been looking for a long time for one and now I have it. It works perfectly and does more than I was expecting it to do.

Better than the KGC-9044

Written By Mr. Anderson, Los Angeles, CA. on Monday, September 22, 2008
 
This little thing sounds better than the Kenwood 9044...the larger EQ with
detachable face. I tried'em both and smaller was better. Bass hits harder,
highs sound crispier. It also takes up lesser space!

Small but big in output!

Written By 718-612-****, Philadelphia, PA on Sunday, July 15, 2007
 
Well I had one last year and I can say it's very good EQ to have you get all three outputs and for a passwive eq to be that small it's a monster as long as you have the proper amp to push it. I myself was very impressed about the sound quality one thing about EQ's they have to be graounded very well or you will have a ground noise and those dog gawn, noise ioslators take the ground noise out but they take alot of your sound quality so make sure you ground it good and who ever purchases this item well be a big Kenwood fan, I can say I have not been disappointed with anything I got from Kenwood.

Bang for the Buck

Written By Ron, Lorton, Virginia on Monday, August 08, 2005
 
easy to install (can litterally go anywhere) ads more adjustment capabillity than any head unit e.q. and the sub cut button is by itself worth having the unit for when you're pulling into a neighborhood or the mall and you don't want your subs thumpin. Great unit--can't beat it for the price (i've had three now-I get another one every time i do a new system. Hope this helps !!!

Great equalizer but very small

Written By Ken, SE Florida on Tuesday, June 07, 2005
Crutchfield Customer Review (What's this?)
 
This is an easy to install easy to use equalizer. I mounted it into the pocket under my head unit in my Mustang. It works perfectly. The only thing you must realize (And the only reason I gave it a 4 instead of a 5) is that this thing is SMALL. It is a little tough to get used to the short throw of the slide controls and they have to be "Nudged" rather than slid. This is also what makes it very versatile as you could mount it anywhere. In my opinion it was worth the trade off to still have some of my pocket left to hold small items rather then taking up the whole opening.
