I have an old P/A system from a cop car that I'd like to install. I know this is probably sounds silly lol but i want to mess with my friends and people with it. I'm not the best when it comes to putting new electronic devices like this into cars.

Anyone have any advice or step-by-step references? I was thinking maybe I can splice the power off the wire feeding my kenwood ddx419, and then run a fuse or something idk. I don't really feel like drilling any holes through the firewall to run wires.

 

firewall already has 2 holes
peek on the firewall under the dash
drivers side
big grommet with a 'tit' you cut to add a wire
you new yorkers
dont call me for bail $$

 

you can also run a "add a fuse" to the fusebox. i did this for my dimming mirror install

 

Not for the amount of current his 'cop' PA will require.
Those puppies are rated for 100Watts into one speaker (8 Ohm)
and for 200Watts when connected to two speakers (4 Ohm).
I would go directly to the battery and properly fuse the wire there.

Those pull TWENTY AMPS when in use. 70mA stand-by.
The manufacturer recommends straight to the battery for power.


Dimming mirrors generally only require 1 amp max if that...
