BotoBoi808 Posted April 18, 2007 Report Share Posted April 18, 2007 I installed a D3 in my 07 Civic Si. I hooked up an aftermarket sub and amp to the HU. I used the Non-Fading output and the remote turn on. I also did the bypass. The bypass works fine, but for some reason there is minimal sound coming from my sub. When I undid the bypass (removed and placed the mute wire in it's original position and ungrounded mute wire) my sub worked just fine. Has anyone ran into this problem?

scrupul0us Posted April 18, 2007 Report Share Posted April 18, 2007 is the sub woofer output turned on on the deck? Menu -> AV Menu -> Sound -> Subwoofer is your sub amp turned up? Quote Link to post Share on other sites

I tried three different kinds of RCA's, all with the same result. Checked the grounds and they was all good. I played with with every sound mechanism on the HU with no positive results. When I put the mute wire back to the original spot though, everything was good. Quote Link to post Share on other sites
scrupul0us Posted April 18, 2007 Report Share Posted April 18, 2007 when you move the mute wire back (removing the bypass) are you hooking it up to anything? if so, what Quote Link to post Share on other sites
BotoBoi808 Posted April 18, 2007 Author Report Share Posted April 18, 2007 when you move the mute wire back (removing the bypass) are you hooking it up to anything? if so, what Nope. I just let it hang there like normal. Quote Link to post Share on other sites
scrupul0us Posted April 18, 2007 Report Share Posted April 18, 2007 well that makes no sense to me then... i mean i guess u could try amping up the level to the woofer on the woofer menu what amp are u using for your subs? Quote Link to post Share on other sites
BotoBoi808 Posted April 18, 2007 Author Report Share Posted April 18, 2007 I played with every sound setting on the HU, including the subwoofer and non fading level settings. My point is I have the D3 hooked up the way it's supposed to be hooked up and it works fine. When I do the bypass, none of the preout's work, well, they do, but there is very little sound coming from the sub. I have a RE Audio 12.1 Mono Class D for my RE Audio SE 12" Sub.

naplesbill Posted April 18, 2007 Report Share Posted April 18, 2007 I would try grounding the bypass to a seperate ground than the radio. It sounds like the additional ground is pulling away from the other grounds. Quote Link to post Share on other sites

naplesbill Posted April 18, 2007 Report Share Posted April 18, 2007 Yes, ground it to a metal point in the dash somewhere. It sounds like your grounding in insufficient when the bypass is included. This should provide the necessary grounding without taking away from anything else. Quote Link to post Share on other sites
