I say buy one.
I got mine mounted on the front "rack" it took snugging the included ties several times after the initial install to get it truly secure, but it was worth it.
a true 450 wat sterio, just need an imput such as an mp3 player or you can sync it to your phone via Bluetooth.
can hear it well even at 45-50 mph.
note it will not fit on your front rack unless the rabbit ears have been removed.
I didn't use the included cig lighter socket. I got a bar clamp 12 volt cigarette lighter socket/duel 5 volt usb charger with an on/off switch. it just hooks to the battery. just make sure to turn off the switch when you are not riding, or I often play it with the scoot hooked to the battery tender without issues.
if you really wanted to you could wire the socket so it only comes on with the key, but as long as you get the 12v adapter with the switch its not needed and I like not needing the key to turn on the jams
