Question, im looking to do a project soon, i had a thread on here before about putting some 18's in a trunk and alot of guys suggested me do a wall. I have never attempted such a huge feat and quite frankly, scared to! But, on the other hand i could actually do it. Can anyone point me in the right direction on what materials i would need? Some decent 18's (used or new) and how do i go by designing a wall? its a 2002 pontiac grand prix! and maybe 2-18 inch Fi's. I looked on these threads and boy, its a lot of work to wall some subs. Does anybody charge to design me a wall with a cut sheet? and how much. I never done anything like this and definately cant afford for someone to do it for me!! But, i want to give it a shot. Also does anybody else make 18's besides Fi and Sundown which they are reasonably priced?
