hatrix Posted August 25, 2010 Report Share Posted August 25, 2010 So in my car i currently have the following: Fi SSD 18" w/ 9cuft box @ 32hz Old 380w soundstream amp powering it (temporarily) Alpine SPR-13S components Hifonics HFi100.2 for the alpines Pioneer DEH-2100IB I have a set of 8 gauge wire running to the soundstream amp as its only 15 amps. The Hifonics has 4 gauge wire. I recently got the hifonics for my front stage. Before i installed it there was no buzzing in my speakers. Once i installed it I had a buzzing problem. So, ok, ground issue. I redid all my grounds. Grounds coming off battery: First ground: Second ground: First amps ground: Second amps ground & head unit ground (no metal behind head unit to ground to): Didn't fix the buzzing problem. So I rerouted my RCAs which were on the same side as the power wiring, thinking that must be the problem. Still didn't fix it. I was told about the pico fuse problem with Pioneer decks, so i went about soldering the board today, put it back in and still had buzzing. I'm not sure what else to do besides buy a ground loop isolator, but I heard those can degrade sound quality, or half the volume etc. I really want to fix the problem without using one, but I'm lost on this. Anyone have any idea how I can fix this ? Quote Fi SSD 18/ 9cuft @ 32hz Link to comment Share on other sites More sharing options...
MeanGreen03 Posted August 25, 2010 Report Share Posted August 25, 2010 I'm in the same boat as you too except I have alternator whine. Very frustrating needless to say! Quote Link to comment Share on other sites More sharing options...

Boon Posted August 30, 2010 Report Share Posted August 30, 2010 I'm just gonna put it out there that those aren't what I would call good grounds. But the source of your issue, I'm 99% sure, if your Pioneer deck. You've probably blown the fusible link on the RCA circuit, if it has one, or the stupid 'resettable thermal link' they use in the new ones has popped and not reset. Like most of them.

hatrix Posted September 6, 2010 Author Report Share Posted September 6, 2010 The grounds couldn't have been that bad, because i put ring terminals on and bolted all of them. There is still buzzing. And i already soldered my pico fuse on my pioneer, which did absolutely nothing. Quote Fi SSD 18/ 9cuft @ 32hz Link to comment Share on other sites More sharing options...
deeje Posted September 7, 2010 Report Share Posted September 7, 2010 They all looked pinched underneath a piece of metal to me and with self tappers.
