I have a 2001 Jeep and i really want a sub. I dont want two 10's and a giant box as i go skiing a lot and i need the trunk space so i was thinking of getting a powered sub and putting it under my rear seat. Has anyone done this? Know which ones fit and work best? I already have a replaced head unit but stock speakers its a lot cheaper at this stage to just do the powered sub. Thanks guys! :listenmus
