[QUOTE="528hz, post: 8039328, member: 581076"] Alright guys this is killing me...first tiime I've ever had an issue with a voltage drop after everything proper is installed. Now to start off, I'm not going to name the company, because I don't want this thread going the wrong direction. The problem may in fact be my error... This may be a lengthy post, but I'll try to hit the high points... I'm running an RF 2500bdcp for my sub, an RF 600.4 for my highs.
