Overview

Kicker's KS-Series pairs a 2.75 inch midrange and tweeter into one driver, built to drop into factory speaker locations used by GM, Chrysler, Subaru, Toyota and Jeep. Three included brackets aim to match the factory opening rather than requiring a new cutout.

Component speakers like this run as part of a two-way or three-way system rather than alone, since a 2.75 inch driver only covers the mid and upper range. The included brackets are the real selling point here: matching an OEM opening avoids cutting or fabricating a new mount. At 4 ohms and a 15 to 50 watt recommended range, it pairs best with modest factory or aftermarket power rather than a high output amp.

4 ohm impedance
15 to 50 watt recommended power range
Three included brackets for factory-location fitment

Who it's for

Suits owners upgrading factory speaker locations in GM, Chrysler, Subaru, Toyota or Jeep vehicles who want a direct fit midrange without cutting sheet metal. Not a standalone full range option, since it needs a woofer or full range speaker to cover bass.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

Three brackets cover several factory speaker openings
4 ohm impedance matches most factory wiring
Sized to slot into existing mounts without cutting

What to check first

Only covers mid and upper frequencies, needs a matching woofer
Recommended power tops out at 50 watts per channel
Bracket fit is vehicle specific, not universal

Performance notes

The three included brackets are designed to match GM, Chrysler, Subaru, Toyota and Jeep factory openings, so fit depends on which bracket suits the vehicle rather than on universal sizing. Power handling of 15 to 50 watts recommended keeps it in factory-amp or modest aftermarket territory; pushing it well beyond that risks distortion rather than added output.

Frequently asked

Questions about the Kicker component speakers

Common buyer questions answered straight from the product spec data - no fluff, no "it depends".

Will the Kicker 51KSC2704 fit my factory speaker location?

It ships with three bracket options built for GM, Chrysler, Subaru, Toyota and Jeep factory openings, so fit depends on which bracket matches your vehicle.

What amp power does the KS-Series 2.75 inch speaker need?

Kicker recommends 15 to 50 watts per channel, so check your head unit or amp output against that range before installing.

Can I use this as the only speaker in a door?

No, it is a midrange/tweeter unit meant to work alongside a woofer or full range speaker in a component setup, not as a standalone driver.
