  1. So looking to do an upgraded ground from the alternator to the battery. Don’t really want to struggle to get to a bolt that’s holding the alternator would the location in the photo work?
  2. With the U10 what probably the smallest box size you would use them in. Recommended is 1 cube. Looking to over power them cleanly as well .
  3. So looking at box specs I plugged in to ultimate car audio app it shows my bandwidth from 24hz to 63hz. The app says set ssf to 24hz I have tuning of 32hz and says set lpf at 63hz. Well my smd cc1 Manual agrees with the ssf setting but says for a 10 inch sub with a 24db slope set the lpf at 125hz. So how many people have had luck with that not sure what to go by .
  4. Looks like the recommended tuning on sundowns website for the U series has changed from 32hz to 35hz picking up my new box tomorrow was designed for 32hz will I be ok with that vs 35hz that is recommended now?
  5. I am a iPhone user so really looking at Apple Music but not sure how it is. Tidal looks good as well the 9.99 plan between the two Anyone got any experience with them really just want the best sounds and ease of use.
  6. The Scion tC is a hatchback that’s why I was thinking sub/port up at the glass vs toward the rear of car but most people say will not sound as good idk.
  7. one other thing with that box it is subs and port on same side. the car is a hatch back scion TC would you fire back or fire up?
  8. Ok so we pulled the trigger did two U 10’s D4’s on a sae 3k in one of the D4S pro fab pre fab boxes ... box is said tuned to 32hz , ok that’s befor any said sub displacement is calculated. With the two U 10’s that’s 0.42 of displacement that’s moving the box tuning up to about 35.5hz ! I see sundown website says 32hz l is what’s recommended. Should we do poly fil in the box? If so how much to take away the displacement of the subs? Do not want to invert the subs at all.
  9. My slope is 24db . The subs are two sa10 rev 2 on a sundown saz 1200 set with the dd1 for -10db . The only way it sounds good to me and my Cousin that I’m tuning for is below 56hz. SSF set to 28hz .
  10. I am using a dd1 and cc1 and going by the manuals.
  11. So the question is with a box say tuned at 32hz is that bringing the over frequency range down to have top end lpf set at 50 to 60hz ? Box I have now has an sa10 right under 1.0 cubic foot tuned at 32 hz displacement probably has it about 34hz imo but when I set my lpf with my smd cc1 at 100hz to 125hz it sounds absolutely terrible. Once I try dropping down to 60 to 80 it gets a little better. Is this normal for 10’s ported?
  12. I have a box that has a single terminal it’s a down4sound pro pre fab I have two sundown U10’s in it on a sundown sae 3k subs all wired in Parallel to each other then to the single terminal using 10 ga knu wire. Is that terminal safe for the wattage? Looking at the smd terminal the hole needs to be a .75 larger and I have no way to make the hole larger so best option?
  13. With the sae 3k I’m torn right now between the sa 10 and the U10 . I know sundown subs are underrated but also the amps. I’m sort of leaning towards the new sa.v2 most people I see running the sfb 3k on a pair. Would I gain much going with the u10’s I see most doing 4K on a pair. I’m thinking I could run at half ohm but not sure how the sae line like half Ohm. I have no plans on a larger amp . Not sure what my best option is.
  14. So Two sundown sa 15’s in sealed box or two U10’s ported tuned to 32hz amp would be a sundown sae 3k . What would be over all louder? Don’t know anything much on the U’s never heard them in person. Can’t really fit two 12’s and give the much room to breath in proper box. So my picks is 15’s sealed in the hatch or two 10’s nice big ported box.
