Product Details

Kicker C84 Comp Series 8" Subwoofer 4 Ohm

Kicker Comp™ Subwoofer Series delivers the best bass for the buck! Legendary Kicker bass and possibly the world’s greatest value for under $100. The Comp Series is the best balance between high value and high performance in Kicker’s lineup. All Comp Series subwoofers are versatile, performing in vented or sealed enclosures, and in free-air applications as well.

The C84 Comp Series 8", 4 ohm subwoofer is equipped with all of the proven Kicker construction that you find in elite Kicker woofers, including: the stiffest injection-molded cone with flex-killing 360° back bracing, coil cooling perimeter venting, high-temp voice coil wire, and Spiralead™ tinsel-lead technology for ultimate durability.

Easy-to-use nickel-plated push terminals, a resilient steel basket, and yellow double-stitched surround make Kicker's C84 subwoofer look as good as it sounds. If all of this isn't enough... the C84 leaves enough cash left over to throw down on a powerful Kicker amplifier to unlock optimum subwoofer performance.

Available in four different sizes (8", 10", 12" and 15"), three different impedances (2, 4, and 8 ohm), with dual voice coil variants also available in 12" and 15" sizes.

Kicker C84 Comp Series 8" Subwoofer 4 Ohm

Good afternoon, I'm purchasing an 8" woofer to be placed upside down in the trunk of my motorcycle. My question is do I need to add a spacer between the speaker & the trunk floor

The Technical Guide says the power handling is 55 watts for the ported boxes. Why is this different from the 100 watts in sealed boxes? Will this driver work well in a 1.2 ft^3 box with a 2 inch port and a 100 watt (RMS) amp?

Asked by: Codys456
The power ratings they provide are taking cone excursion into consideration. The ported boxes will reach excursion limits faster, hence the lower power recommendations. This driver will work fine in that volume with 100 watts, but you will need to keep an eye on the excursion and not overdrive the cone at higher levels.

in a sealed box aplication (boombox setup) will this subwoofer work properly on 68 watts? what type of alimentation i need to drive the amplifier (2x40w+1x68w ; lepai lp-168ha) on his max output? thanks

Asked by: inTime
Yes, 68 watts will provide a good amount of output for this driver. The power supply included with that amplifier is 5A which will be sufficient.

Could a 35 watt amp run this sub?

Trying to replace the sub in a Lexus es300, and the head unit only pushes 35 watts to the sub. Would this kicker sub fry the amp? Because I've heard of that happening if a sub with a RMS rating higher than that of the head unit is used.
Asked by: Nikolajczyk
35 watts will drive the sub just fine just not to any of its limits. I wouldn't worry about the amp but if you clip the signal (overdrive the amplifier) you can actually hurt the woofer. It's not uncommon to use a higher powered woofer in factory stereos like this simply because its impossible to fine a 35 watt 8" woofer these days.
