Sheena Posted December 3, 2011 Report Share Posted December 3, 2011 I just got my Skar Audio VVX 12"s about an hour ago and i was wondering if my box was too small? it sounds like its distorting at an estimated 5-700 watts (guessing, no proof) the amp is a brand new Hifonics Brutus 1200.1 and im probably getting about 13+ voltage on stock electrical. am i retarded and just need to let them break in? or rebuild time? box specs: Height: 15.5 Width: 37 Length: 18.5 Port: Height: 14 Width: 3 Length: 23 Displacement: .36 #of common walls: 3 3.78 NET 31.66 HZ tuning I possibly do have loading issues for one of the subs, about 20% of the sub has the port wall behind it (not right behind it, but at least 6+ inches behind it) if i missed anything just ask any ideas? 09 Civic EX KDC-X395 (2) SKAR Audio VVX-12 Skar Audio SK-1500.1 4 cu ft @32 (new box and more port soon) Firing Forward not sealed off Stock 80 Amp Alt Big 3 In 1/0 Knu 2 Runs To The Back 1 Pos 1 Neg In 1/0 Knu DD-1'd 13.8v drop Link to comment Share on other sites More sharing options...

poorfish88 Posted December 3, 2011 Report Share Posted December 3, 2011 Do you have your crossover set? A good starting point is around 80hz, that's all I can think of. Link to comment Share on other sites More sharing options...

Bmike Posted December 3, 2011 Report Share Posted December 3, 2011 your sub sonic should be a few hertz below tuning, 15 is way too low, try 27 , 28 ish , that alone will help 2007 trailblazer lthead unit- pioneer p4300dvd crescendo ft-1 supertweeters pioneer m650 pros audiocontrol 2xs crossover Rockford fosgate p200-2 highsrockford fosgate p400-2 mids1- fi btl 18amps- saz 3500battery- evermax in front, 2 9a31 dekas in rearwires all knuconceptz 1/0 and rcas Link to comment Share on other sites More sharing options...
Sheena Posted December 3, 2011 Author Report Share Posted December 3, 2011 Really? I heard subsonic isn't exactly right on and that it could rise 5+hz (I could be wrong) After this movie I'll go turn it to at least like 23 (or where I think 23 is) I listen to rap mostly so I want 25+hz open 09 Civic EX KDC-X395 (2) SKAR Audio VVX-12 Skar Audio SK-1500.1 4 cu ft @32 (new box and more port soon) Firing Forward not sealed off Stock 80 Amp Alt Big 3 In 1/0 Knu 2 Runs To The Back 1 Pos 1 Neg In 1/0 Knu DD-1'd 13.8v drop Link to comment Share on other sites More sharing options...
Decaf Posted December 3, 2011 Report Share Posted December 3, 2011 are you sure they are wired correctly? headunit settings? (volume used, eq, bass level, sub level, etc) wheres the gain actually at? Link to comment Share on other sites More sharing options...
Sheena Posted December 3, 2011 Author Report Share Posted December 3, 2011 1 ohm nominal (dual 4s) measured on the amp at 1.1 ohm with the amp off Head unit at -4 bass (goes to -6 and is set this way because it controlls the door speakers Volume (37/40) Gain at half on the amp, I really hope it's not clipping, I heard the amp does at least rated It is a stock head unit, but I did a direct swap with the subs in the same box. (went from .24 displacement @ 800 Wrms (2 subs) to .36 displacement @ 1200 Wrms (2 subs)) 2009 Honda civic ex, seats down, firing forward NOT sealed off for now. I know, face the box towards the rear until sealed off, but RATTLES. Louder than the music sometimes. Anything that I'm missing? 09 Civic EX KDC-X395 (2) SKAR Audio VVX-12 Skar Audio SK-1500.1 4 cu ft @32 (new box and more port soon) Firing Forward not sealed off Stock 80 Amp Alt Big 3 In 1/0 Knu 2 Runs To The Back 1 Pos 1 Neg In 1/0 Knu DD-1'd 13.8v drop Link to comment Share on other sites More sharing options...
