What do you guys think ? I am thinking of replacing my 12" Infinity Kappa Perfect sub that sits in a sealed box in my trunk with an 8" Fosgate P28S4 Sub. I will probably make a sealed rectangular box and mount it where the original Bose sub was located so that it will directly feed into seating area. Do you think I will get pretty good bass? Just want something for lower end fill and give me more room in the trunk, the box for the 12 tends to get in the way at times.
