Why not just get the original? Last time I got them, I got a bunch and they were cheap.

Where did you get them.....there are obsolete.

Try "quest components" that's where I bought mine. They were not cheap but working on these amps a lot I figured I would buy a bunch, even though they rarely fail I am probably good.

I can send you one if you would like. PM with your address or you can give me your number.

thanks for the info. You don't have to send me one, i will save that lifeline for something in the future though. I looked that company up and will placing an order tomorrow. If you need to order RCA jacks for amps specifically the type with one set of inputs and one set for pass thru. I found them at MCM Electronics, i lucked out and was able to get them for around a $1.25 on sale. Its so much faster than removing the old one to repair the shield ground and they are identical to rockfords. Expect the white and red indicator are in the wrong place, which is an easy fix. Just cut the plastic tab on the back and slide the fronts off, switch the colors, and melt plastic tab on the back again. Just thought i would share, that way you don't have to get them from ebay.

Thanks for the info. I have 100's of sets for each style of Rockford amp. I bought them years ago and all the colors are in the right spot. I have the singles for the HD amps, the doubles both configurations and the triples.

Really, that is crazy!!! I bet you have a vast array of spare parts.

Ok so here are the readings for the 5110 IC's

U2000 U2010 speaker terminals = 79v
1= 0.646v 0.631v
2= 3.208v 0.413v
3= 0.024v 0.026v
4= 3.236v 0.411v
5= 4.97v 0.023v
6= 10.60v 10.66v
7= 4.98v 0.024v
8= 9.69v 9.66v
