Let's Take a Walk Down the Kicker Car Audio/Stereo Isle.

Huge selection of kicker car audio/stereo car amplifiers, car subwoofers, and car speakers at OnlineCarStereo your car electronics super-store

Let's visit the Kicker isle in the warehouse at our car audio/stereo store.



Here you'll find a plethora of car stereo system amplifiers like the (08)ZX850.4 (08ZX8504) 4 channel car amplifier. This car system multi-channel amplifier deliversa whopping 215 watts x 4 at 2 Ohms and 175 watts x 4 at 4 Ohms. That’s truly alot of power; more than most car speakers can handle. Be sure to pair it with carspeakers like the 3-Way 6" x 9"  08KS6930 and alwaysremember to properly adjust your amplifier gain controls!  
If the 08ZX850.4 delivers more power than you need, take a look at Kicker's(08)ZX350.4 (08ZX3504) car amplifier. This compact amplifier delivers 90 wattsx 4 at 2 Ohms and 60 watts 4x 4 at 4 Ohms. This is more than enough power formost car audio coaxial and component speakers. Look for a set of car speakerslike Kicker's 07DS650 and the 08KS690; both of which feature RMSpower handling in right range for optimal performance. 

No car audio/stereo system is would be complete without bass and this is where Kicker really shines. For the true bass-head, Kicker's monstrous (08)ZX2500.1 (08ZX25001) pushes out so much power your subs won’t know what hit em! At a whopping 2500 watts x 1 @ 2 Ohms; this car amplifier gives out enough power to push three  12" (08S12L74/08S12L72) or two 15" (08S15L74/08S15L72) L7 Solo Baric car subwoofers.
Of course, mind bending bass isn't everyone's cup of tea. Some of us simply want enough bass to really accentuate our music and increase the over-all sound quality. Don't worry friends, Kicker hasn't forgotten you. A pair of CVT shallow subwoofers (07CVT102) will do the trick. These space-saving, low-profile car subwoofers will add a nice level of bass to your system without over-powering your mids and highs. Run these subwoofers with a (08)ZX300.1 (08ZX3001) 1-channel mono car amplifier, which also features a compact form factor, and you'll be in for some no-hassle, easy to install, musical bliss.

I have these in a ported box tuned to 38hz with an internal volume of 2.01 cubic feet. They’re mounted inward on top of the box so everyone can see the magnets, with the ports pointing towards the back. I built the box myself for my '00 Montero Sport, separate chambers with cross bracing and double sheet baffle of 3/4inch MDF. Right now I'm still breaking them in pushing only 120watts to each speaker. After break-in period of 50hrs, I will bridge my amps. Using Blaupunkt PCA2120 amps, 1 per sub, 300watts RMS w/350 max dynamic.

This is the 2009 version of the 3011's with improved cone designs. Thanks for free upgrade OCS... I'm not going to tell you these are the best subs in the world because they aren't, but I will tell you they are amazing for the price. They are very fast and pick up a good range. They hit very hard. When I first wired these baby's up I was very surprised. I am more than happy with them. These can blow away many sub-woofers that cost double the price. If you just want some good loud base for a cheap price this is the perfect sub for you. Also OCS's price was very good. At my local electronics store these subs retail for $140.00 plus tax.
