What are the benefits in doing an IB setup? The cons? I'm wanting to do something completely different with this car, than I have normally. I was thinking either an IB setup on the rear deck with 8's, or a nice t-line with a single or dual 8's. I have no clue what to do when it comes to either, but I'm fairly sure I could do the IB setup with some guidance, but the T-Line would have to be built by someone on here, most likely.
