Changed to line level and I lose my volume control. I don’t get the volume indicator. No sound out of the center speaker and no chimes. No voltage on the speaker lead as well. Current 727-01-01 : 18A2 1808 xxx Tried 18A1 1808 xxx 18A2 1808 xxx ---

You need to tell the APIM that you don’t have an OEM DSP any more. 7D0-01-01. ---

Current APIM 7D0-01-01: 2A2A 0006 xxx still get no signal with Front & Rear set to LL in the ACM. Set Front/Rear to variable run a frequency through my phone via bluetooth audio and scoped it. Volume is around 25. Sorry I didn’t have my thumb drive to capture a picture. I just snapped it with my phone. ![](https://i.imgur.com/JgOf9A2.jpg?1) ---

I think I messed up and told you to set it to line level, I wasn’t thinking variable line level. Sorry. Good signal! ---

No worries. Having issue getting sound through the DSP, going to the AMP works great. Through the DSP I get no sound. Not sure if its a short behind the steering wheel 🙂 or if the unit itself. ---

I should be able to still run the RCA to the DSP if I go back to default? If I pull out the RCA slightly so the shield isn’t touching I get sound through. ---

You mean the new DSP… > [@JetFixxxer](#): > > If I pull out the RCA slightly so the shield isn’t touching I get sound through. You have a wiring error where the DSP is shorting the balanced audio to ground. You need to wire as unbalanced or use a bal to unbal transformer or line converter. (Here we are back to that.) I thought the Dayton DSP was balanced audio input? ---

Never had an old DSP I don’t have a non-Sony and B&O, but yes the new DSP. ---

I thought so as well, but out of the 3 channels only 1 is working without having to pull it out a little. So I was thinking just go back to default settings in FORScan. I might just get the line converter… was worth a shot. 🙂 ---

Use the line converter with the line level you have now will be much cleaner. Or… Wire the RCA’s as unbalanced: Use the positive channel output (+) to the RCA center pin. Use the Shield or Ground to the ring. Discard the channel negative wire (-). ---

I want the cleaner option. I will get a line converter. Any suggestions on which one? ---

I would just get a passive converter, no power needed. Much cleaner and easier. Kind of like this… but not speaker level. [Scosche LOC80 2-channel line output converter at Crutchfield](https://www.crutchfield.com/p_142LOC80/Scosche-LOC80.html?tp=2001) ---

Not sure if this matters, but at the beginning of this I did change the ACM EQ settings to 00 (Flat). If I want to disable the center speaker. I will need to set AUX2 = Not Used and 9=CC Do Not Check for Open, AAM Not Present, non-Convertible, Chimes Enabled ---

i use the PAC SNI-35 on a sub feed from the Sony DSP/Amp. I would like line level but I wasn’t going nuts on that, just added more amplifier to drive the replacement speaker. No issues. The others will work also. ---

Don’t see the not to check for the Front or Rear speakers for the 2018 and up ACM. I went with the PAC SNI-35. ---
