conley916 Posted February 15, 2018 Report Share Posted February 15, 2018 My buddy sold me his Sundown 1500.1 and I was looking at two SKAR SDR-12s or two Sundown SA 12s for my 2015 Dodge Challenger. I guess I would just like to know the differences between subs besides SKAR being significantly cheaper. Thank you. 2015 Dodge Challenger Scat Pack audio coming soon Link to comment Share on other sites More sharing options...

alex912005 Posted February 15, 2018 Report Share Posted February 15, 2018 They look kind of the same on paper, both have 2.5 inch coils but the Sundowns have more xmax so should be able to get louder in theory. But versus threads are not allowed here because they generally turn into a shit show. My Build Log Link to comment Share on other sites More sharing options...
anr102990 Posted February 15, 2018 Report Share Posted February 15, 2018 Not supposed to discuss “VS” threads, but the SDR series is new and I haven’t yet to know anyone who has them or have even seen them installed yet. Between the two I’d go with SA series. I personally have one skar DDX 12 at one ohm on an rp 1500 in stock electrical and it honestly moves quite a bit of air In my supercrew f150. Either way , build or have an enclosure built for it that’s right for your application. But anyways I believe the sundown sa series is pretty close in comparison to the DDX I have so I believe you would be satisfied. Good luck Link to comment Share on other sites More sharing options...
WalledSonic Posted February 15, 2018 Report Share Posted February 15, 2018 One is a Chinese built sub built by a budget company and another is a Chinese built sub built by a quality company that wanted to introduce a budget line of subs. Either way, @PaCiFiKbAllA and @anr102990 nailed the responses. These subs are basically the same, just put one in a proper volume with a proper port and you wont know the difference.

WalledSonic Posted February 15, 2018 Report Share Posted February 15, 2018 Since rent-a-modding is also against the rules, I add value where I can without trying to play mod or support versus conversations. Mods dont really moderate the forum very much these days, so its easier just to add value or avoid a shit thread altogether.

ckeeler11 Posted February 15, 2018 Report Share Posted February 15, 2018 Sundown has a good reputation and builds solid products. Skar has a history of not being very customer friendly, and doing some shady things. Link to comment Share on other sites More sharing options...
