Our take on the Kenwood KGC-4042A

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.

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.
