SoundAlert 100W Emergency Police Siren Kit [118-124dB Slim Speaker] [2 x 16A Switch Control] [Hands-Free Air Horn] [PTT Mic] [Radio Rebroadcast] Warning PA System for Emergency Vehicle Trucks Cars

The unit itself is easy to wire- takes about 30-45 minutes as long as youre able to located a grommet in your firewall. Two things I dislike about this unit- 1) Too quiet. I mounted this in front of the bumper and I can still barely hear it at max volume on highways or when Im moving. 2) The two wires that go speaker itself .. could be a tad bit longer. I noticed that I barely had enough wire when I went to mount the speaker on the front passenger side grille.

Only had and used this unit for about a month - - very satisfied - - loud / clear / easy to install (did not hook up to vehicle horn button) so only Power lead - ground and 2 speaker leads - - - mounted behind grill - - - - -

Extremely easy to install and mount. Very! Very LOUD!!!! Great deal.

I have had this for years and I have had to replace the speaker 3 times. Its not reliable and they will not help either.

It is very loud and easy to install.

This is very heavy duty, well made, and eardrum popping loud

Its fun to mess around with and the max volume is really loud, youll love it. Ive had it for about two months and havent ran into any issues yet.

Definitely will turn heads. If you arent careful this thing will have you in handcuffs in no time.

Worth the money

With the instructions inside the box products everything is easier
