What to look for:

Besides giving you tight tonal control over your music playback, the equalizers available from Crutchfield also offer you plenty of other useful features.

• Each of our EQs offers a front-to-rear fader for dual-amp balancing, even with a receiver that has only one pair of preamp outputs. The fader is also ideal for dialing in just the right amount of rear-fill.
• Some units have a "listening position" switch to let you adjust the stereo image from left to right to compensate for "side-biased" listening.
