V70: Stereo/SatNav/Phone - Aftermarket stereo problem

D5786 · Feb 8th, 2018, 01:43

Evening everyone

I've just replaced my accent HU-850 with something more contemporary. But, after fitting everything back together it only turns out the rear audio signal is sending a low frequency sound. Is there anyway to restore the original sound wave? Also, When i turn the stereo off my front speakers make a unusual sound from the front speaker. Once i lock the car or take the face off; the sound briefly stops and resumes. It's absolutely annoying when I'm parked up having to put up with the horrible hissing sound!

STEREO : Sony MEX-N4000BT

DOLBY PATCH TO RCA WITH TWO RCA FOR MY SPEAKERS.

I'LL DEEPLY APPRECIATE IT FOR ANYONE ABLE TO SHED SOME LIGHT!

You've posted in the 2007 onwards section rather than https://www.volvoforums.org.uk/forumdisplay.php?f=19

Some kind moderator may move it for you

If you've had the HU850, what have done about the amp under the seat? RCA connectors are line-level outputs so I wouldn't have expected those to drive speakers unless you're feeding into the original amp. Have you got more details about how you've connected it all up?

I know on my 2003 v70 I just bought the dedicated wire harness and all worked well. Only downfall was I lost the ability to change the sound settings that were on the Volvo radio eg 3 way channel sound, Dolby. All the speakers were just on. Didn't experience any hissing though. If you have any good car stereo places near by maybe worth calling in for advice.
