my polks are in stock locations, and my solo is built in. my amps are located just behind the top with a home made amp rack with pass threw ports to move the sound into the car (like the "X" isnt loud enough to get there, lol )with two 3" fans blowing in them at all times. oh, and the amp for the polks is under the back pass seat(cut out the bottom of the seat and framed it back in , looks 100% stock till you lift seat) thats why i got the square sub, it fits nice in back without taking space away from top of the trunk. its a nice flush fit with the top of the well. any round speaker that hits that hard and that size would call for more air space.
oh, and i still do lose sound when the top goes down, lol
