ZDudas Posted February 26, 2013 Report Share Posted February 26, 2013 (edited) Ok I bought 2 Sundown SD-2 12's for my 95 Regular Cab Dodge Ram 1500. I did separate prefab boxes (one behind each seat) and I'm not pleased. I am planning on building some boxes built to Sundown specs 1.0 Cubic Feet per sub. If I build a box closer to Sundowns specs will it be much better than what I have them in now---prefab. I think it is like .65 cu feet right now, for each sub. I got 550 watts RMS running to each of them right now. 1100 watts RMS total Edited February 26, 2013 by ZDudas Quote Link to comment Share on other sites More sharing options...
Krakin Posted February 26, 2013 Report Share Posted February 26, 2013 A custom box is almost always going to sound better then prefab.

Afficionado Posted February 26, 2013 Report Share Posted February 26, 2013 you can't really expect much sound out of a 0.65 cu ft prefab box..

dfoland93 Posted February 26, 2013 Report Share Posted February 26, 2013 If you make a custom box to specs from the company then it will be your best option Quote The spot with least resistance LOL. I would ground to a rubber dildo if it had less resistance than a run of 4/0 wiring. how many poeple work there 3 or 4 lol At crescendo HQ? probably 2-3 At the sweatshop in china? 30,000 children No Engine Link to comment Share on other sites More sharing options...
Krakin Posted February 26, 2013 Report Share Posted February 26, 2013 Make sure when you make your box(s), presuming that you make sealed boxes, 1.1 cubic feet total to make up for the driver displacement. Or 2.2 cubic feet if you put both in the same box.

ZDudas Posted February 26, 2013 Author Report Share Posted February 26, 2013 I'm doing 2 separate boxes. One behind each seat. The way I got the design right now the new boxes will have 1.06 cu ft each. Width-21 inches Depth-8 inches Height-15 I checked on Rockford Fosgate box wizard and it said that those dimensions will give me 1.06 cu ft. Will that be good enough, or do I need to try and make it a little bit bigger. Building out of 5/8 mdf. Building boxes Friday night. Quote Link to comment Share on other sites More sharing options...
ZDudas Posted February 26, 2013 Author Report Share Posted February 26, 2013 Ill just go up an inch on the height and it will give me 1.14 cubic feet according to the Rockford Box Wizard. Width - 21 inches Height - 16 inches Depth - 8 inches Quote Link to comment Share on other sites More sharing options...
Krakin Posted February 26, 2013 Report Share Posted February 26, 2013 You should be fine with those dimensions. Having a single cab myself I know how hard it is to make boxes bigger to fit back in that small of a space.

ZDudas Posted February 26, 2013 Author Report Share Posted February 26, 2013 you can't really expect much sound out of a 0.65 cu ft prefab box.. Didn't even subtract woofer displacement. Probably sitting on 0.50 cu feet. Quote Link to comment Share on other sites More sharing options...
Krakin Posted February 26, 2013 Report Share Posted February 26, 2013 (edited) If you make your own box you'll get a much better overall sound. Get those SD-2 12's and put them in there on a good amp and you'll be more then satisfied with the results. Even if you don't get a new amp you'll notice a huge difference in the quality of the bass your getting. But if you do get one make sure you do some research on the electrical stuff you need to do to stay safe. There are plenty of thread on hear to help you out, and if you ever get lost or need some clarification don't hesitate to ask for help. The people hear will always try to help you and get everything done right.
