I recently purchased a new Mazda 3s. The stock stereo isn't bad, but I miss my bass. I have never been much of a fan of using high pass to hook up my amp's. Does anyone know if there is a dash kit for an aftermarket stereo? Also, if anyone is looking for springs or performance parts that you can't find elsewhere, there is a store in Portland, OR that deals strictly in mazda. Here is thier web address: www.corksport.com. If they don't have what you are looking for, there is a good chance they are in the procces of fabricating it. I would be very appreciative for any help in reguards to the dash kit. Thank you.
