Add up to four 8" full-range woofers to your Harley Bagger with the Aggressor Pro 880 kit. This kit makes mounting two 8" speakers in each saddlebag quick, easy, and clean. Precision machined entirely from high-density plastic with steel threaded mounting points, this kit adds the structural integrity needed to support 2 high-power speakers. Complete with powder-coated pressed steel grills and all stainless steel hardware, this kit guarantees a spectacular end result. 

Due to the exceptionally large amount of cone surface area, excursion, and efficiency that four 8" pro audio speakers have to offer, this kit delivers much more output than can be achieved with other speaker arrangements, such as two 6x9s alone. 

Exceptional Sound Quality 
Clear undistorted output. Made specifically for pro audio type speakers (not subwoofers). Because pro audio speakers are designed to play clearly at extreme volume levels for hours on end, pro audio speakers are much less stressed than a car audio-type speaker in this application. Car audio-type speakers do have their place but just can't compare in this kind of application. Drum strikes have a profound amount of force that you can feel just like live music. Much more dramatic than even very high-end home or car audio systems typically can deliver.  

Totally Stealth
This kit can be used with or without lid speakers. This kit is much louder than lid speakers alone. This means that you can build a system that is totally stealthy if you like. No visual queues that your bike even has a sound system, yet you have "melt your face off" loud sound.

What's Not Included

Several speakers are a direct bolt-on fit for these mounts. Here is a list of our favorite speakers to use with the Pro 880 kits.

  • Diamond Audio HXM8. These speakers are truly full-range, screaming loud, better bass than pro audio type speakers, best-sounding right out of the box without having to do a lot of adjustments.  
  • AP8. These speakers have a great bass response. They play deeper than pro audio type 8" woofers. They can be paired with horns for a full-range sound. Sold in pairs.
