IKnowImLost224 Posted February 27, 2012 Report Share Posted February 27, 2012 I recently switched from a pioneer DEH-4000UB to a pioneer MVH-p8200bt and ever since any set of subs I have had are not loud at all. Both H/U have 4v pre outs, and I tested it with the new MVH. I purchased new kicker RCAs (which were needed), a Sundown SAZ-2500D (old amp: power Acoustik BAMF 4000/1d), and a RE XXX 15" dual 2. The original setup I had with the old h/u was the BAMF and two alpine type x and it was much louder. Nothing has sounded good with this new h/u. I may switch back but I wanna know why this h/u is making my subs sound like poop Quote Link to comment Share on other sites More sharing options...
Decaf Posted February 27, 2012 Report Share Posted February 27, 2012 Ive owned the mvh... what are the settings/volume you are using Quote Link to comment Share on other sites More sharing options...
Skullz Posted February 27, 2012 Report Share Posted February 27, 2012 After looking on sonixelectronics that H/U is only 2v pre-out so that is where your losing volume at so you'll need to re-gain your amp for the lower voltage coming in.

IKnowImLost224 Posted February 27, 2012 Author Report Share Posted February 27, 2012 I set the volume at 35 with the dd-1. I tested the output voltage and it's 4v. Look on pioneers website Quote Link to comment Share on other sites More sharing options...
Decaf Posted February 27, 2012 Report Share Posted February 27, 2012 it IS a 4v headunit, thats not the issue. again, what are all your settings on the headunit Quote Link to comment Share on other sites More sharing options...
IKnowImLost224 Posted February 27, 2012 Author Report Share Posted February 27, 2012 Loudness: Mid (without it I get hardly any bass) Subwoofer 2: 125 hz (currently +6) I think those would be the only two that effect sub? Any other ones you can think of or need? Quote Link to comment Share on other sites More sharing options...
IKnowImLost224 Posted February 27, 2012 Author Report Share Posted February 27, 2012 Is there settings in the power off mode? I know if you turned the power off on the DEH there was more menus to change stuff Quote Link to comment Share on other sites More sharing options...
