SVB847 Posted August 14, 2012 Report Share Posted August 14, 2012 I was wondering if anyone would have input regarding something i noticed in my current setup. I am running the equipment in my signature all at the C-Pillar and am very happy w/ the sound and output, however i noticed that if you sit in the rear seats, there is minimal bass compared to the front two seats. It doesnt sound bad, but hardly any pressure versus sitting in the front seats. Is this common with C Pillar walls?.. Not sure if it is because you are not getting the sound of the waves off of the windshield or what.. does anyone have any input on why this may happen? Sorry if this is a dumb question, just something i was curious about. 2000 Chevy SuburbanPioneer AVHP8400BH8 - 18" Fi SP4 Subwoofers (fully loaded) B Pillar 4th Order (75 cubes)2 - Ampere Audio 8.0 TFE AmpsRF T6004 AmpRF T4002 Amp4 - Selenium 8W4P Mids8 - Selenium 6W4P Mids6 - Crescendo XST2 Supertweeters2 - Selenium ST200 SupertweetersDC Power 320 Alt & Js Ultimate 27011 - Group 31 BatsBuild Log:http://www.stevemead...01bdcp-updated/Team GG Link to comment Share on other sites More sharing options...

Guest Posted August 14, 2012 Report Share Posted August 14, 2012 i dont understand why this is either. i mean when i sat in the back seat of blakes suburban when he had the 4th order'd 12 15's, it was way more violent than sitting in the front.

SVB847 Posted August 14, 2012 Author Report Share Posted August 14, 2012 Like you said Kranny maybe because his was a 4th order?

aerickson Posted August 14, 2012 Report Share Posted August 14, 2012 Maybe the sound waves need to compress. And it can't do it that fast in the back seats. Link to comment Share on other sites More sharing options...
SVB847 Posted August 14, 2012 Author Report Share Posted August 14, 2012 Thats what i was thinking.. there is a TON of air movement back there but not the same bass you get up front.. 2000 Chevy SuburbanPioneer AVHP8400BH8 - 18" Fi SP4 Subwoofers (fully loaded) B Pillar 4th Order (75 cubes)2 - Ampere Audio 8.0 TFE AmpsRF T6004 AmpRF T4002 Amp4 - Selenium 8W4P Mids8 - Selenium 6W4P Mids6 - Crescendo XST2 Supertweeters2 - Selenium ST200 SupertweetersDC Power 320 Alt & Js Ultimate 27011 - Group 31 BatsBuild Log:http://www.stevemead...01bdcp-updated/Team GG Link to comment Share on other sites More sharing options...
IndianaBassHead Posted August 14, 2012 Report Share Posted August 14, 2012 I'm not sure either. John Hone's f-350 with a 4th order seems more violent in the back seat also.
