Hey guys, Im a first time subaru owner (07 sport wagon)... love it so far, only 650mi. My first of many questions is suspension related, so im not sure if this is the place to ask. I took my stereo system out of my jeep grand cherokee and wanted to put it in my wagon. It consistes of 2 JL audio W6 subs, and two JL 500/1 amps. Plus a four channel amp for my mids and power caps and a extra battery = (alot of weight). Question is how will that extra weight (app. 200+ lbs) effect handeling. I do plan on aftermarket suspension down the line... figured could get a stiffer spring rate or something. Also how much will it effect my performance?
