Product Description

Ok, so it's only a 200 watt amplifier, but the Kicker Key 200-4 Smart Amplifier packs a ton of features into a small package. Sure, it's a 4 channel amplifier that puts out 50 watts at 4 Ω to all 4 channels but it's also a computerized equalizer and crossover. After the amp has been hooked up to your speakers, you can download the Kicker Test Tones, plug in the microphone, press the selector button, play the tones and let the amplifier self adjust to not only make your sound system louder, but clearer. Even more so than most other amplifiers that produce twice as much power! The internal equalizer self adjusts the crossovers, the 40 band equalizer and time aligns the speaker signals to the position of the microphone so that the sound from all 4 speakers reaches your ears at the appropriate time. Other advanced features such as Auto Compression, limit the input and light up when audio clipping is detected letting you know something is too loud, and a Bi-Amp mode powers tweeters and woofers without a passive crossover allowing only the sounds that each speaker can reproduce through. The 7 3/8 x 2 3/4 x 1 11/16" amplifier features FIT2™ (Fail Safe Integration Technology) which allows it to be used in most any car on the road.

VW Key Amplifier Installation

Our Expert's Take:

We had the choice of any of Kicker's amplifiers to install in our 1971 Super Beetle build, and we installed this amplifier along with a Key 500.1 amp under the rear seat and don't regret it one bit. The compact amp can be mounted close to the battery, out of the way, out of sight, and out of mind. After we tuned the amplifier using the Kicker Test Tones and the included microphone, the amp was fully tuned and the stereo system sounds phenomenal!

Our shipping policy is as follows:
We ONLY ship within the United States and its territories.

Orders over $100 will receive free shipping within the continental United States. Freight on under $100 will be $9.95. Large packages ship FedEx. Smaller packages ship US Priority Mail. Delivery time averages 1-5 business days after it ships.

Most orders to Hawaii, Alaska, APO/FPO, Puerto Rico and other US territories are shipped by the US Postal Service. The shipping costs for these orders are billed at the time of shipping.

For expedited shipping, you must call us. All express orders are personally handled by the representative you speak with in order to streamline the process. Please do not request express shipping via email. Emails are reviewed in the order they are received which could possibly delay your shipping.

Shipping on any returns is the customer's responsibility. If your order qualified for free shipping and a returned item reduces your order below the $100, you will be charged the according shipping cost for the order.


90 Day Return Policy

You can return most unused, never installed, like-new items for 90 days from the date of receipt. Items must be in like-new condition. The following items are final sale:
  • Special order items
  • Special order upholstery
  • Electrical items
  • Installed carburetors
Like-new Condition: JBugs may refuse a return when the returned item is not in like-new condition. These situations will lead to refused returns:
  • Installed items
  • Items missing parts or the original packaging material
  • Items damaged in return shipping due to improper packaging
  • Carburetors that smell like fuel
  • Damage due to customer negligence
  • Items with scour marks that show installation or attempted installation from nuts, bolts, screw-driver’s, washers, etc.

Returns must be sent in a proper shipping box.
With the exception of parts that are shipped to you in the original manufacturer packaging (example - TMI door panels, floor pans, complete front beams, etc), please be sure to return the parts with an external box or protective packaging around the parts you are returning. Most manufacturer packaging boxes are not rated for shipping and can become damaged or destroyed as they are too thin to withstand forces applied during the shipping process. Failure to do so will result in a higher restocking/reboxing fee or outright refusal of the return if the part cannot be restocked in the same condition it arrived at you.
