When i swapped my 05s out the whole seat comes out then i think i had to modify the bracket to make them work... And honestly i didnt notice a huge difference in sound... Now in my 97 the speakers need swapped because they suck.... But if i would buy another 05 i would prolly leave the stock system how it was.... I got more bass from the stocks then what i put in but it worked well when i put a sub in
