My old stolen CD players preouts where 2 volts each

now most high end receivers have voltages of 4 volt or more

how much of a difference to your amp and sub sound quality would a 4 volt output to a 2 volt be?

what about 5 or 6 volt?

my old cd player did not have sub out so

if I plug my mono amp into the sub out does that just allow sub control from the deck or does it help even more?

Higher preamp voltage is to reduce noise, but you generally don't get noise on the subwoofer channel.

Yeah, put the probes on the power wire and ground wire of the amplifier. Multimeter on DC. Do not put it on the wires that go to your speakers. M

It's still a very small company that is growing. And growing has its challenges. He is very active on Facebook and does plenty of real test...
