some one give me a little feed back! ive always thought it was best to give each sub its own chamber then slot port in the middle? lately ive seen alot of boxes where the speakers are pretty much sharing one chamber and L-ported towards the drivers side firing back, is this more effiecient sounding? or is this done so the box can fit better? i have a 2002 accord and i want this setup to be good DAILY. dnt care so much for SQ but more so SPL. meaning SPL to the ear ill doubt i ever see a meter. THANKS FOR ANYTHING GUYS
