Hello have bought me a mazda 323 f ba and would like to build a proper system mainly for rock pure. some colleagues think that I should simply put a bass box in the suitcase room with a final stage and finish but others say prefer to clean 4 3 ways boxes, also brings neat bass and also sounded. what do you think about it? 4 3 ways boxes with 100 watts sinus bring as much bass as ne 300 watts sinus bass box ? MFG david
