I wanna add 2 sas bazookas to my 91 LS400 and a amp also, im still running my stock head unit ( im using my daughters cd player to play my cd's shhhhhhhhhh...) is it hard to hook up? do I have to run new power wires?

 

yes you have to run new power wires and the process really isnt that hard.. look for my thread "installing a sub in Sc400" should be on the second or third page. It is based on an Sc4 but the process is really close to what it wold be in an LS
