2002 Suburban with Alpine Type R’s

Hey guys iam new around here and got some Questions....I have a 2002 suburban iam going with two wedge style boxes facing each other with  (2) 12" type-r's and need a little help. the box size is going to be 23x15x20 (WxHxL) which would give me 1.5 interior volume and a 2 inch vent about 3.5 inchs long tuned to 35hz...How does this sound? any ideas? and were would be the ideal spot to place the port?Suburban boy

ny my calcualtions that comes to about 3.11 cu ft internal. what are the total demensions on your port? 2x3.5xwhat? 3.5 inches is really really short, and may tune the box very high2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

hey, even when i did the box calculation here the box gave 1.5 and when i used the port lenght calculator it gave me about 3.5 inches long...can you tell me if iam doing somthing wrong with the calculations? And what would you recommend, Thanks Suburban boy

your box is 23x15x20 internal would be 21.5x13.5x18.5=5369.625 5369.625/1728=approx 3.11cu ft Are you going to use a round port or square vent? The Calc if you put in your external demensions and .75 for 3/4 MDF then it comes right to 3.1 2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR
