CJ18 Posted November 9, 2012 Report Share Posted November 9, 2012 HI all! Sorry for bad English I want to buy two DC 15XL m2. But only if the box spec are OK. Car - sedan audi a6 c5 (1998). Amp AQ 3500d.1 at 0.5 ohm daily. (or 0.7?))) Box like this fit to my car. Box spec are 3"~ to the each sub. Port = 80sq.in tuning about 36 hz. And when i fold the seat I want to make an additional port, which will add another 20 centimeters? and tuning will be 31-32hz What do you think about it? I would prefer this design for a pair of 15s with 6.1net and 83in2 of port Quote Link to comment Share on other sites More sharing options...
