Im totally lost on what options i should choose when configuring a BTL. Im looking to get a 12". Its gonna be used as a daily speaker in a ported box. im confused about choosing the P chamfer and the cooling part, and the rest of the options lol. I already have an amp that gives 2700 watts RMS, so most likely ill be using this amp unless this isnt safe? please help me in deciding which options i should choose while keeping the things i stated before in mind. Thank you in advanced. please help my noob self as much as possible
