Yeah, me too, but I was just offing up a suggestion. -

BobbyG2 replied to Will Rouse's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
I was once considering doing something like this, and here's what I'd do: - Two separate amps, or a two/4channel. - Build two separate enclosures, or 1 enclosure with two totally separate (sealed from each other) chambers - One for the SA 12(s), with the recommended airspace, tuned to ~20 Hz - One for the SA 8(s), with the recommended airspace, tuned to ~40-50Hz - Make sure that the low pass on the Amp for the SA 12(s) are at or slightly below the tuning frequency for the SA 8 enclosure - Make sure the High pass (Or subsonic) on the amp for the SA 8(s) are at the same frequency it's at for the SA 12(s) low pass - Adjust the Low pass for the SA 8(s) to meet the High pass (or subsonic) for your Mids amp, and adjust them both higher/lower (but still matching) until you feel that it sound right with your components. You might have to make some adjustments to your gain to get the SA 8(s) and SA 12(s) to sound even, but you should have a relatively flat response from <20Hz to whatever you set the SA 8(s) low pass to. -

4 sa-8v.2

They don't need to be in separate chambers. Imo it's less complicated and saves airspace if you just do one chamber, and achieves the same thing if the airspace is the same. -

Yeah, for daily. Tlines essentially free air the sub so you want to stick below or at the highest the rms of the sub so you don't bottom it out. I would stick with a good amp with an rms of half the subs rms to be safe, but if you want to go higher take note of what volume it seems the sub is starting to stress and don't go above that volume or turn the gain down.

Good job man! This would be a great thread for people to follow to learn how to recone. I don't think that putting 1000 watts on it in a tline would be a good idea through

The new Sundown SAX 1500Dv.3 should fit the bill -
lattsa power
BobbyG2 replied to 81000D's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
I'll probably never considerably overpower a sub, even if I know it could take it. Unless maybe if I ever get the worlds highest power handling sub and there's no more options to get louder than to overpower them. Until then, I'll use a high quality amp with high quality subs with matching RMS ratings. -

Might be able to get away with two 250 amp alts but after vehicle draw, and the draw from the amps he's gonna need for his soundstage, two 300 amp alts should barely leave any headroom. Unless he wants a bigger battery bank, but then when he plays it all day his batteries will eventually drain. -

BobbyG2 replied to bneum's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
Damn, what an awesome first system lol 4cu.ft. sounds too small? You seen the magnets yet? Lol 12cu.ft. tuned to 35hz. for daily music With your gains set properly. You'll need a big battery bank (3 XS 3100's at least) and if you're planning a daily build two 300amp alts.
