With today's smartphones hosting a wide variety of listening choices such as stored music, internet radio, podcasts, etc., it is no wonder that customers want to use this as their primary listening source. Bluetooth offers the easiest and most popular connection, KAC-M1824BT is not only your standalone Bluetooth gateway but if used with an in-dash receiver, it will double the power of a typical CD receiver with it's built-in 45Watts x 4 of amplification. A water resistant controller can be used to adjust volume and change tracks.


Many of today's powersports have very limited space to work in and tend to be a harsh environment for electronics because of the exposure to outdoor environments. KENWOOD's compact performance amplifiers are small in size so they fit even the most limited installation areas. The amplifiers also use a conformal coated main PCB (printed circuit boards) which offer extra layers of protection to help prevent moisture or damp air from damaging the product.


The KAC-M1824BT remote control is designed to be mounted in places that are exposed to the elements. To operate in these conditions the remote control has a IPX-5 certification. This water resistant certification is the grade at which a device continues to function when directly subjected to 12.5 L of water per minute from all directions using a 6.3 mm inside diameter nozzle at a distance of approximately 3m for at least 3 minutes. This level of water resistance makes it perfect for ATV, Motorcycles and boats.

Ease of Use:


  • Started out great
    Verified BuyerReviewed by CJNewbie - July 21, 2021

    I loved this amp when I first purchased it I liked the concept of an amp that could get it's signal from Bluetooth. It worked well. It was loud. There were some connectivity issues regarding the remote. It's like it had loose wiring and had to be a certain way to play properly. After I got it connected, everything was fine. I liked not having a head unit. Then, one day it just stopped working. No fuses blown or anything. It just stopped working. I'm going to check the manufacturers warranty and I'll update this if I can get the issue resolved. As of now, the amp is useless to me.

    Very easy to install. I have it on my Can-Am Spyder F3. Works excellent with the right amount of power. I have the Amp bridged using to speakers rated at 400 Max and 100 RMS.

    Ease of Use:

  • Beware of open box purchases
    Verified BuyerReviewed by Colanuttz - April 10, 2021

    This rating isn’t about the product but about open box items! You would think they would check customer returns instead of just listing as open box! What a waste of time!
