I need some questions answered about installing subs. I'm not very knowledgable with this subject so it would be wonderful if you guys could help me out. I want to install 2 12" kicker subs in my prius, with a legacy amp. I would like to know if I would be able to fit the 12"s (with a box as well) in the back, without the seats laying down. I also want a professional to do this, so I understand there might be a large amount of cash involved. Would I have to get a new dash to install everything or can the wires be run through the dash and everything be A okay?
