Posted August 29, 200916 yr I tried to set the gains on some amps with a DMM and a test tone cd but I could not read the good values on the DMM. One of the Amps is an sax 1000 Sundown at 1 ohm : so I should read sqr(1000 x 1) = more than 30 volts. I don't remember the right number, but I had the good number when doing it. the maximum I read was 21.7 volts, withe knob to the max!What may be the problem? How can I do the good settings?The DMM is brand new, maybe it is a bad one. Hope not!So, I had to set it by ears. Help me, please!
August 29, 200916 yr 32v if going by that method.increase preout on your headunit if your stereo can do that.Dont leave gain at max if that's what you did.Keep head unit volume 75% of max volume it can go.Keep bass and all eq settings at 0.
August 29, 200916 yr Author I did not left the gain at max! No, no !Eq was flat, like all settings, volume at 3/4.How to increase pre outs on the Pioneer 88prs? It's'the european model of the 880 prs (the last and black model). Maybe the DMM is not good enough. Can it be that I don't have a good enough electrical system? I am on stock battery, stock alternator,...The maximum voltage I can read on my voltmeter is 13,8 with sound off!!!BTW I've just found a local dealer of Kinetic and XS batteries : which one to buy, I don't know. Maybe I will buy the little one made for Honda Civic. What do you think of all that?
