[QUOTE="DarkFox, post: 3531441, member: 567531"] Hello, I have been having a problem with my new setup and here is what I have been able to come up with: Problem: Noise through mids and highs (wine) Attempted Fixes: New Ground for radio (Pioneer DEH-P780MP) Redo ground for amps new RCAs The Pioneer fix from the noise sticky Isolators Went to the car stereo store down the road and they say that the problem is with the RCA inputs on my amp. That the Pioneer radio does not mesh well with my Hifonics Titan Amp ([URL="http://www.sonicelectronix.com/item_6553_Hifonics+Titan+TXi+4406.html"]http://www.sonicelectronix.com/item_6553_Hifonics+Titan+TXi+4406.html[/URL]) and that a amp like a JL would fix it. Now I am not sure as to the difference in differential and non-differential inputs, however I noticed on the maxxsonics web page that the Brutus amp is advertised as having, "The ZXi differential inputs combat electrical noises right at front of the amp’s input RCA’s." while the Titan series says nothing about this, leading me to believe that maybe they do not have differential inputs and that upgrading to a Brutus may be a fix for me. All I know is that as it stands now, if I have just the fronts, or just the rears plugged in, I do not get noise, but when I plug them all in, I get noise. any help would be great. Thanks [/QUOTE]
