Speaker Specifications

Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
Midrange (Midwoofer)
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Not Specified by Manufacturer
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Not Specified by Manufacturer
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
400 watts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20000 Hz
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Boss MC300 motorcycle speaker system

December 9, 2012

I mounted my system on an 850 cc utility quad ATV. It has been thrashed quite a bit over the last several months and the system is still working. I regularly pressure wash it, and mounted the amp inside the headlight pod, but the speakers get hosed alot and still work great. Low to medium quality sound but fairly loud. I use it for GPS voice nav and occasional music.

is thismp3compatable?
A shopper on Aug 7, 2014
Best Answer: Yes. The system has a built in amplifier that you power (preferably to a toggle or acc switch) the actual speakers connect to anything that has an aux jack. Phones mp3s ect.

Can you power these with 12v USB power adapter?
Popster on Feb 8, 2015
Best Answer: no unfortunatlly u can not, they r setup to get conected to your fusebox besides your motorcycle battery, im assuming u r purchasing this for your motorcycle but if u r getting them for a boat or atv it would be similar, but the usb adapter would still serve a good purpose because you could charge your mp3 player or cell phone etc, they sound great by the way, great sound for the price...
