On my TSX, if I put the volume over 10 on the factory head unit, I get a terrible buzzing from my subs and the rest of my speakers. And to get rid of it, I have to both turn off the amp cut off and also the head unit, and I have to lower the volume below 10. I had a previous post about feedback that I have on my system, which PNA did a terrible job. I was just looking for a temporary fix to get rid of this loud humming coming from my system until I have time to take it to StreetEffectz or Movin On to take care of everything else and tweak it. The noise is unbearable and it sounds like it is going to blow my speakers.

 

What gear do you have? And how is it interfaced with the HU for signal and remote turn on?

 

I have the 6 speed manual, and the amps go directly to the head units original feed to the factory amp. Is that what you needed to know?

 

What Ken was asking was what BRAND of equipment to do you have and how is it connected to the factory headunit? Are you using LOC's or did the shop do the direct preamp connections without the use of the LOC?

 

Before I bought my new equipment, I had another system in which I used the preamp outputs. PNA took those outputs and connected LOC's to them, even though I just insisted to them to soder the connections that I previously had. So not only did they beat me for an extra $50 for them, they also did a horrible job.
