Box Design Suggestion
This is for my extended cab Sonoma, not the Impala. Have a pair of Fosgate Punch P2 8s, built the box to RF specs, .65cuft ported with 2" x 8.8" port,sounds ok but think it could be better. Oh, driving the with a Punch 500.1tb @ 1ohm. Seen some boxes built to Sundown SA8 specs and are said to be hitting very hard.
