I have 2 rockford P2 15" d on a TMA amplifier 500.1 in a 4.5 Cu. Ft. Box ported. I'm in the process to get 2 Bl 12" d2 and I need the know if the HIFONICS BRUTUS BXi2608D will be a good option (cheap one) in a 5.0Cu. Ft. This will go in the trunk of a Toyota Yaris 5 door. My budget is pretty tight, that the main reason why I decided the BXi2608D. Here are the pics of my trunk Visit My Website
