Thomas Cawley Posted February 15, 2013 Report Share Posted February 15, 2013 Hey guy's, I am new to the forums and to Sundown Audio. I have just received 3 SA8 V2's that I will be running @ 1.3 Ohms powered by a RF T1500-1BDCP (hopefully enough power). My dilemma is I drive a 93 Chevy Silverado Single cab so my options for an enclosure are limited. It will be an angled box with the subs firing down (braced 3" off the ground) and the port facing the passenger side wall. My question is..... Do the numbers below add up? I am getting conflicting calculations from different programs i.e. different cubic feet sizes, port sizes etc..etc.. So if anyone can confirm the below numbers your help is greatly appreciated.

Thomas Cawley Posted February 17, 2013 Author Report Share Posted February 17, 2013 would this do? http://www.flickr.com/photos/93321064@N08/8484156010/in/photostream Quote Link to comment Share on other sites More sharing options...
Pro7 Posted February 18, 2013 Report Share Posted February 18, 2013 Nooo, he meant you want 12" of port per ft^3 Right now you have 4... And honestly 12 is a bit low, those sa8s will probably want 14-16 with how much excursion they have Quote I've gotten a blowjob and picked up my iphone behind her back to see what email notification I got from smd before Link to comment Share on other sites More sharing options...
Thomas Cawley Posted February 19, 2013 Author Report Share Posted February 19, 2013 Sorry for the back and forth, but how about this? And does the airspace size after speaker and port displacement look right? http://www.flickr.com/photos/93321064@N08/8488765082/in/photostream/lightbox/ And this is what I'm basically trying to build for 3 of them. (not my photo but if it's yours and you would like me to remove please let me know) http://www.flickr.com/photos/93321064@N08/8487672463/in/photostream/lightbox/ Quote Link to comment Share on other sites More sharing options...
Thomas Cawley Posted February 21, 2013 Author Report Share Posted February 21, 2013 thanks for the help guys, should have this box built and tested in the next few days. Quote Link to comment Share on other sites More sharing options...
Thomas Cawley Posted March 19, 2013 Author Report Share Posted March 19, 2013 Box is built, sounds great for 3 x 8's lol. So my next quest will be the big 3 upgrade. (Power/Ground/Alternator upgrade) like I stated earlier I am running a RF Power T1500, should I turn the infrasonic filter on and at what frequency and gain should I run the amp at? Thanks for the help. Quote Link to comment Share on other sites More sharing options...
