robertdbardos Posted May 11, 2016 Report Posted May 11, 2016 I have this setup 2 SA-12's 4 ohm CT Sounds 1400.1 Currently on 4g wire I haven't had the $$ to upgrade yet. My box is vented nothing special Up until yesterday I was running an Alpine 600.1 and my system hit hard so I wanted to upgrade my amp found a CT Sounds I wired my SA's to 1 ohm and now it sounds like I'm using a sealed box in theory I doubled my power but I'm not feeling it. .. What gives? Quote
Ron36 Posted May 11, 2016 Report Posted May 11, 2016 (edited) Those subs can handle that amp all day has to be a box issue, what's your port specs , I bet since u opened up some power u are choking the subs. Box needs to be 3 to 4 cubes tuned to 35 hz.

robertdbardos Posted May 11, 2016 Author Report Posted May 11, 2016 Just a basic vented box for 2 12s im doing some research on boxes right now i believe that is the start of it Recommended Ported Box: 2.0ft^3 (Tune to 35Hz, yields F3 of 28Hz) What the hell does yields F3 of 28Hz mean. Quote
Ron36 Posted May 11, 2016 Report Posted May 11, 2016 (edited) Box is to small for starters, I would lean towards 4 cubes sundown love room .

robertdbardos Posted May 11, 2016 Author Report Posted May 11, 2016 I don't have much more room to play with lol Quote
Ron36 Posted May 11, 2016 Report Posted May 11, 2016 (edited) Im rockin 3 sa-10's in a sealed because of room issues sounds great but would rather do ported. Could think about sealed Edited May 11, 2016 by Ron36 Quote 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery
reedal Posted May 11, 2016 Report Posted May 11, 2016 He hasn't said what his box specs are and you're already saying they're too small? F3 is the point at which your enclosure is 3dB less than your tuning frequency. So with what you stated as being sundowns recommended enclosure specs, for a single SA-12, 2cubic feet net volume, port tuned to 35hz, you will be down 3dB at 28hz. Using what sundown recommends, you would build an enclosure that is 4 cubic feet net volume tuned to 35hz for your two SA-12's. Is your current enclosure a prefab that you bought online somewhere, or did you build it as per a design or what?

Ron36 Posted May 11, 2016 Report Posted May 11, 2016 (edited) His box is 2 cubes at least that's what I gathered Edited May 11, 2016 by Ron36 Quote 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery
robertdbardos Posted May 11, 2016 Author Report Posted May 11, 2016 It's a prefab box I just took a picture but can't figure out how to upload it... Quote
reedal Posted May 11, 2016 Report Posted May 11, 2016 His box is 2 cubes at least that's what I gathered No, those are the specs from sundown that he was quoting Quote SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32
