Apologies on the delay. You probably already found your answers but install was easy, took less than 20 minutes and the price is listed on legmakers website, no discounts here.def looks cool....and if you get some sound out of it...probably worth it..may i ask what it cost ya..and how much was it to install..
I have something very similar I keep in the garage and toss in the car should we be making any long road trips.Regarding the flashlight:
I have had and currently have vehicles with a rechargeable flashlight, but now only use FENIX flashlights. The one I really like for my vehicles is the FENIX UC35 V2.0 RECHARGEABLE FLASHLIGHT. It is small and can be recharged in the vehicle using one of the USB ports. The beam range is incredible on this small flashlight.
The problem I have ran into in the past is that I forget to charge them so having one that auto recharges any time the car is running WITHOUT using up a USB or power socket and having wires in the way, is ideal. But probably a silly mod for most, never claimed I was sane.
