Our take on the Clarion SRK604

by Leigh Schoettinger

Clarion's SRK604 center channel speaker solves the problem of limited space, fitting conveniently into your car's single-DIN dash opening. The enclosure houses two midbass drivers, a dome tweeter, and a built-in amplifier to create a "front row" feel in the driver's seat.

A built-in amplifier gives the speakers plenty of juice to keep up with the rest of your multi-channel system. Dual dome midrange speakers deliver accurate reproduction of the all-important vocal range, while the tweeter brightens the mix with all the high-frequency details. You'll hear improved clarity and imaging from your DVDs and CDs.

Adjust the front panel level control to tune the speaker to your system. The speaker also features a subwoofer input and output so you can adjust your system's bass with the front panel subwoofer level control. The speaker mounts in your vehicle's single-DIN dash opening above or below your aftermarket stereo, or you can surface-mount it on your dashboard with the supplied mounting brackets.

Crutchfield Customer Review (What's this?)
I wanted to get a center channel so I could set up a 5.1 system in my car. I am currently running 4 seperates, with a kenwood powered sub. This speaker setup complimented my system perfectly, and the 1 din fit in my 2003 Honda Element worked perfectly. Small bit of trouble getting it in the dash kit, but beyond that, looks ok. Sound quality is excellent with the JVC AVX33 deck I have in car, and watching a movie in a car enviroment is awesome in 5.1. I would recommend it.
