What amplifier power does the Kicker CompR need?

It is rated at 800 W RMS and 1600 W peak. Match it with an amplifier that delivers close to its RMS rating at 2 ohms or 8 ohms, depending on how you wire the dual 4-ohm coils.

Can I wire the dual 4-ohm coils to 2 ohms?

Yes. Wiring the two 4-ohm coils in parallel gives a 2-ohm load; wiring them in series gives 8 ohms. Choose the wiring that matches your amplifier's stable impedance.

Does it work in a sealed box?

Yes, it is designed for sealed enclosures and also works in ported boxes. Sealed gives tighter, more accurate bass; ported gives more output but needs a larger box.

How much mounting depth does it need?

It needs about 7-15/16 inches of mounting depth, so check your enclosure and vehicle space before buying. It is not a shallow-mount sub.

Is the CompR a good upgrade over the Kicker Comp?

Yes, it handles more power and adds forced-air cooling for better reliability at high volume. It is a clear step up if your amplifier and box can support it.

The subwoofer comes with mounting hardware and terminal connections. An enclosure and amplifier are sold separately.

Our take on the Kicker CompR Subwoofer

The Kicker CompR is a car subwoofer built for high output on modest power. Its dual 4-ohm voice coils let you wire to 2 or 8 ohms, and forced-air cooling through the pole piece keeps the motor cooler under long, loud play. Reviewers rate it highly for bass output per dollar and durability, though it needs a proper sealed or ported box and real amplifier power to shine. It is a step up from entry-level Kicker Comp subs in power handling and cooling, but it is not a shallow-mount driver and demands mounting depth.

Pros

800 W RMS and 1600 W peak handling
Dual 4-ohm voice coils allow flexible wiring
Forced-air cooling improves reliability at high volume
Injection-molded polypropylene cone with Santoprene surround
Wide 25-500 Hz frequency response

Cons

Needs a large enclosure and about 8 inches of mounting depth
Not shallow-mount, so it will not fit tight spaces
Requires a capable amplifier to reach its potential
Sealed-box output is tighter but less loud than ported
