    SOUNDS AWESOME, COMPACT& HEAVY DUTY!
  

*by S***H on Reviewed in the United States on January 14, 2013*

I got this PA speaker for my 01 Yukon Denali. with the provided mounting bracket, I was able to mount it behind the grill(i like things looking as clean and stock as possible) and it was a perfect fit.  I also painted it black so it can't really be seen but can definitely be heard!!!  I have it hooked up to my cobra 29 lx cb radio that has a PA speaker outlet.  You do need a mono plug to connect the speaker wires to so it will be accepted by the cb radio output.  It is definitely loud and clear.  Instead of having to buy noise makers, just download an app on your phone and play it through the mic. Great speaker at a great price...well worth it.  It is also very heavy duty an can see it work great on commercial/fleet vehicles.

    it is a good deal. I drive a diesel truck so for ...
  

*by M***. on Reviewed in the United States on March 7, 2015*

Just installed this is my vehicle for my CB radio. It seems much louder than my previous PA horn, but not as loud as I was expecting. Beware, it is very large. It took me a long time to find a feasible location for the installation. I would say for the  money, if you want a little additional sound, it is a good deal. I drive a diesel truck so for me I need the little extra. If you don't need that additional sound, go for a cheaper PA horn it will work just fine and will be easier to install in the engine compartment.

    So far, so good.  Very happy with this speaker
  

*by L***O on Reviewed in the United States on August 25, 2014*

I have this speaker installed in my truck as the speaker for a Whelen Air Horn/Siren unit.  It's mounted semi behind my license plate up front so while somewhat protected it is still exposed to the elements.  So far, so good.  It is EXTREMELY loud, weighs a ton and seems to be built very well.  Conveniently enough, water does not collect in it as I thought it would, and even after several heavy rainstorms and driving through a very real hurricane it works perfectly and does not seem muffled at all.  As I said, so far, so good.
