very low RCA voltage

[warr40 10+ year member]

Hi, im having a problem with my RCA's

My front and rear are reading only .2 volts AC at 1khz test tone

And my sub pre-out is only reading .6 volts AC at 60hz test tone

The deck is a Alpine DVA-9861

My old system 2 12" kickers with a vibe amp and a sundown 100.2 pushing cdt comps worked fine

But now this HU seems like it wont even push my two new nine.2's

that sucks maybe the rcas are fuked

did u turn up the volume.....

Are you testing this with the volume turned all the way up? Because most HUs don't produce full voltage until volume is maxed....And are you testing DC or AC voltage? and try this...Unplug the rcas from the amp and test from there touching the neg probe to the outside of the RCA and the pos probe to the "probe" of the rca cable.

EDIT: Missed the AC voltage part... lol

Should tell you something^^^ But if it is still reading low 1.5-2volts then get a line driver that will solve any RCA voltage prob you will ever have...

well now im not getting anything at the back of the deck at full volume

fcuk

Explain how you are testing the voltage..

 

[warr40 10+ year member]

dmm with posite probe on the inner part of the RCA with the neg probe on the outer edge testing AC voltage

COuld this be a ground problem?

this died quickly

Did you have a track playing this time? I would suggest plugging one of the rcas in so you have some sound so you know for sure something is coming through. Then if you measure and still get almost nothing... you KNOW your measurements are not right.

i took a reading with both rca out and put the dmm right up to the RCA jacks on the HU

and took a reading from the ends of the RCAs with them plugged in

I know on my Alpine 7995 you don't get any voltage unless you have your sub level turned up, it's not a boost.

 

[PIITB Wut Wut 10+ year member]

yep... kenwood is same way... sub level works more as a limiter

make sure it's 0dB with volume near max

 

[warr40 10+ year member]

yeap its a 0db and i have my sub level all the way up n volume all the way up

are my RCA's shot?
