Mikey Bates Posted June 5, 2012 Report Share Posted June 5, 2012 Current Setup 1999 Jeep Grand Cherokee HU Kenwood KDC - 352U Concept HPN - 1500 Skar VVX 15 D4 Custom Box Tuned to ~32Hz Cadence 4 Gauge Power and Ground Wire Stock speakers, big 3 is NOT done Problem It seems that when i use the DD1 properly (To my knowledge) It hurts the SPL in my car. When i tune everything by ear, give or take, it seems to get louder. Plain and simple. HU settings for DD1 Bass - 0 Mid - 0 Treble - 0 Sub Volume - 0 (goes -15 to +15 so 0 is the middle) HPF 150hz, (only effects door speakers) LPF set to trough because i just use the one on my mono amp After trial and error, i turned my EQ to Bass -8 Mid - -8 Treble +1 By doing so, i turned my Sub volume up to +7 to make up for the loss in bass (still volume 35 undistorted) Steps i did for the DD1 Plugged RCAs into it from the HU (sub out) Played 40Hz at 0db provided by SMD online via Ipod USB, also did with the CD on same HU settings and with both, achieved full volume of 35 with no distortion. I Proceeded and did the amp as i'm supposed to (not listen it lol its strait from directions. I used track 5, the middle db of 3 and 7 No matter what i seem to do some songs still clip and my sub bottoms (i think thats the term i want) this is pro due to what the song was recorded at as i know its clean. . . So my problem is that after all this, if i go through and tune everything by ear, still used 35 and max volume, i seems to get it louder and not distort as much as when i use the DD1 i think i described everything well enough, sorry if i repeated or over did it but looking for any explanations, ideas, input. thanks guys Quote Link to comment Share on other sites More sharing options...
Torres Posted June 5, 2012 Report Share Posted June 5, 2012 second to last line...'it seems to get louder and not distort as much as when i use the DD1' yeah umm....how do you know this? if you don't use the DD1, then you don't know you're not distorting. if you use the DD1, you'll be set at the point right before clipping, given you're playing a properly recorded song. anything higher and it's distortion city Quote Link to comment Share on other sites More sharing options...

soundstream15 Posted June 5, 2012 Report Share Posted June 5, 2012 a soft clip is not gonna hurt your subs. you got to turn the sub level control up all the way or pretty damn close to get voltage out of the pre outs, so turn that up and set everything and you should notice a difference Quote Link to comment Share on other sites More sharing options...

Mikey Bates Posted June 5, 2012 Author Report Share Posted June 5, 2012 my sub. mids and highs sound shitty, but you can cleary hear the sub difference, and it loses loudness as well Quote Link to comment Share on other sites More sharing options...
CleanSierra Posted June 5, 2012 Report Share Posted June 5, 2012 Also.....bottoming out could be because of the box design(or lack thereof). What were your box specs again?
