I needed to know on if putting a stereo in a tl, its a 10 in sub w/ 2 amps and power core cap. My question is is this going to weigh the back of the car down on the springs very much, i really want to maintain the speed of the car but also have it sound good. the box and all should wiegh in at about 150 for all of it. What do you guys think and also, if you have any pics, please post em, i would be curious to see some. . .
