Wanna upgrade my stock speakers on 2008 streetglide

150 it will fit no bigger MOPAR KENNY

You must use a special pump that you can get from the dealer. I think it's normal to run from 5 to 7 psi.

sounds like the security system.

Although I'm not that familiar with the StreetGlide, I think it's a variant of the Road King. If the oil tank is on the bottom of the transmission, there will be two drain plugs on the bottom of the transmission. One in the middle of the tranny and on towards the front left side. The one on the front left side is the oil drain. The one in the center is the transmission oil drain.

If in doubt, loosen the plug just enough to allow a few drops to seep out and look at what comes out. It should be dark colored and not smell like gear oil. Capacity is probably four quarts 20W50 petroleum based or synthetic oil. The bike came from the factory with H-D Syn3 oil in it.

These shocks have weaker gaskets in them, They do provide a rougher rider once worn in..
You can get,
FXDBI Street Bob shocks or
Fxdwgi Dyna Wide Glide shocks or
FABTECHS OR WILBERTS

I'm not sure of the system that comes stock in your wrangler but what I like to do is replace the stock speakers with infinity perfect speakers. You can find out on the internet exactly what sizes are stock then usually I just buy them off ebay. If you look them up there are a lot of brand new in box with free shipping. The infinity perfect speakers I think have the best overall sound for the price. If it still isn't loud enough for you get your self a little 200 watt amp and use an inline splice with the factory Rear speaker wires behind your head unit and for the inputs to the amp. Make sure and leave the stock wiring so if u want to sell the jeep but keep the speakers; all you have to do is unplug and go.
