DSR1

Missed that. They must not have setup the gains right like you said.

I don't know how the OP did the integration. I used a DSR1 set to 4V input with the weblink desktop from Maestro.
Then in the Mosconi Pico 8/10 that i now use i set the input to -2dB when running the headunit at 30. No clipping of the signal there and after tuning the speakers and outputs i have plenty of volume. 15 is plenty loud and my SPL meter said it's around 90dB. Can i trust the SPL-meter? I don't know, but i also do not care. It's loud enough that i will probably never exceed 15 on the volume anyway. So if the OP says 23 is not loud enough he either has some severe hearing conditions or the gain structure simply sucks and he leaves a lot of volume on the table.

How did the shop interface your aftermarket amps with the factory head unit? Did they use a harness? Did they tie in before the factory amp (low-level) or after (high-level)?

I have low-level signals feeding my DSP and 5 channel amp. I have my gains set properly to use the entire range on the volume knob. I can turn the volume all the way to max before clipping starts.

Sound to me like the shop tied into the high-level signals which are going to be noisier and start to clip right around 23 on the dial.

The road noise is likely drowning out the music. These cars have a lot of road noise. Sitting still I comfortably listen at 10 but rolling down the street I will need to turn it up higher a few ticks on the dial. Nature of the beast.

They got the signal directly from the stock amp is what I was told. Also, did you disable factory EQ with forscan?

No need for ForScan if using the DSR1 for integration.

This tells me you are not using a DSR1. You didn't mention one in your first post.

Did the installer grab the low-level signals before the amp or did they tap into the speaker outputs of the amp?

If they tapped into the speaker outputs, that explains why your system sounds bad.

agree. It is being altered twice. The dsr1 is suppose to bypass.

Do you have a link for the dsr1 and anything else I'd need?

Shouldn't my Alpine DSP already be doing what the DSR1 is supposed to do? Considering it's also a DSP.

Not the integration. That’s the Maestro part of the DSR1. I have a Mosconi Pico 8/10 for DSP, but still use the DSR1 for integration.

Thanks for the help!

Sorry, got one more forscan question. People seem to be saying if you change 727-01-01 to xx5A you will get clean output with no clipping. But on that line there is no option to write.

I have to correct me.
With the Mosconi PICO 8/10 DSP amplifier i can measure the electrical inputs to the DSP.
With volume level 3 there is an 8dB bump in the bass compared to Volume level 30, which is measuring flat.
This is with "00" at the appropriate ForScan Code for the ACM.
So it looks like that you cannot get rid of the bass boost, except if someone else has found out how to disable the bass boost.

I participated in that thread in 2018 already.
