About the Speakers ↓

High volume sound with smooth silk dome tweeters. This speaker upgrade kit is perfect for anyone who has extremely high sound quality expectations but still wants to be able to play loud. 

Customized Just for Street Glides

All hardware you need for a full install and we even pre-wire it for you. We built this kit to be plug & play with '14 and up Harley Street Glides. The woofers drop right in, match up to the factory bolt holes. The silk dome tweeters come already mounted in stamped steel Street Glide specific speaker grills. The passive crossovers have been modified so that they are compact enough to fit on either side of the radio and we even put matching plugs on so that no wires need to be cut on your bike. 

The Woofer

The MPK woofers are some of our favorite 6.5 inch speakers to use in Street Glide fairings. Punchy bass and smooth/loud mids. They perform spectacularly well in the factory speaker pods. We recommend sealing the pods with one of our gasket kits that you can find here. This increases the bass punch and the power handling.  

The Tweeters

The silk dome tweeters are loud and bold but do not sound harsh like other loud tweeters do. The MPK tweeters are definitely our first choice for sound quality.

About the Amplifier ↓

The all new Micro8 line of amplifiers are essentially the same amplifier as the very popular Micro series amplifiers but with more power. The Micro84U is 275 Watts RMS per channel at 2 ohms instead of 150 watts like the Micro4v2. That's crazy power per channel, and it's all based on the proven Micro amplifier design. 

660 Watts RMS

• 90 W x 4 @ 4Ω
• 165 W x 4 @ 2Ω
• 275 W x 2 @ 4Ω Bridged
• S/N: ≤ 100 dBA / THD: .2%
• Remote Level Control Included

Fitment Notes: This amplifier is identical in size to the Micro4v2. This amplifier easily fits in the fairing of any Harley bagger '98 through '19. Our Bond-in amp racks for saddlebags work well with this amplifier

• Dimensions:
9 x 4 x 1.64 inches
230.5 x 103 x 41.8mm
