Pac LD-10 Line Driver Wiring

Why would you put red (positive) to blue (remote)? Red to red (switched power) and black to black (ground).

I use a PAC LD10, but my configuration is very unique because I use it to boost the signal from my phone directly into the amp. 

I wired the positive to a switch so I can turn it on and off, the same switch also controls the remote turn on lead to my amp.  

Never had any buzzing issues like you described. Maybe try grounding to the chassis instead of the radio harness. 

It is important to not wire the LOC power input directly to the head unit remote.  It says to use a relay to isolate the unit from the remote output because the remote output can only source a few milliamps.  Always a good idea to have the power for the LOC turn on/off with the head unit.  Add a relay as recommended.  That won't help the buzzing but it will prevent damage to the head unit.

Buzzing is usually a signal grounding issue.  As mentioned, a long ground wire is not recommended.  Ground at the amp chassis ground.   Ensure that's a proper ground connection (tight, bolted, bare metal, etc).

So it doesnt have constant power draw.

From manufacturer: Connect red wire to a 12V+ DC constant source, a switched ACC power, or 
 a relay switched by a remote Amplifier turn-on lead.

SWITCHED doesnt stay on all the time. Notice it says a RELAY when using the remote wire?

feel better?

So it's junk because it wasn't installed correctly? Makes total sense... :tomatofa:

I hooked it up the correct way the 2nd time lol. I do think its lacking sound quality for my taste

It just boosts the signal that is fed into it, if the input signal ***** to begin with then the output will **** too. 

I only play test tones through mine for strictly SPL purposes so I can't comment on its actual sound quality.

My hu only has 2v output. It's a cheap pioneer double din. The outputs sound great. I was just trying to boost the volts.  With the pac hooked up it sounds like its traveling down a long hallway (if that makes sense)  I may try and get the Dayton dsp

You might as well bypass the headunit and run your audio through bluetooth straight to the Dayton DSP. @Jeffdachef swears by this method. 

or just get a head unit with a higher pre-out voltage from the start
