Hi everyone im new to sub enclosure building, could people please help with advice and even plans if possible for a build. I have a DD715d2 off a t15001bd in a toyota corolla hatch. im looking to get as close to to 5cf as possible but looks like 4.7ish is all i can fit. My maximum dimensions are 985mm wide, 440mm deep and 400mm high. Im looking for a ported box that can put out the most boom.. Thankyou to anyone who can help. This is what i was thinking 4.73 in mm.pdf
