I have 4 15" kicker's in my car right now running off 2 hifonics 2006's. i am thinking about putting either 4 18's into a truck or 2 18's of the trunk of my car. i want to flex and have a lot of bass. i already sound loud i my car but i want more. do you think i am jumping out there to far with purchasing 4 fi btl 18's? and if so what sloutions do any of you have for me to get flex and more bass? I will probably using the same amps or buying the slightly higher rated brutus. Oh just fyi the car is a lincoln towncar
