Would you like it salted or unsalted? lol It's so cold even the car washes are closed!

No heated car washes in your area? There's one not too far from me, have to see if it's still open.

We really need someone to a scope or rta on the stock amp and see when the roll offs start happening. Just before is probably where line levels should be set and considered the max volume of the system.

The MS8 sorta does this, kinda. During calibration checks, with a white noise sample disc track playing, it measures THD/clipping points. The 2010 Sony setup clipped early, right about 2/3rds in. The 2013 Non-Sony played to 100% without tripping the MS8 up at all. I still backed it down to 90% before doing calibration though.

So the signal clips at 2/3 of the volume setting on the OEM head unit?
So should I set max system volume at 1/2 to get the cleanest signal with a little extra headroom.

I think Lanson told us clipping on the ms8 did not occur in his 2013... he just backed off 10% on the master volume to leave headroom.

I have the Sony system.

Well then 2/3 should be the starting max but if the sound is shaped before that it still shouldn't be turn up past flat response.

One of the processors measures the response just before clipping and you leave the volume there. Then you have to use a separate volume control.

This may have been answered already, and I apologize if it was. Which speakers did you tap into for your subwoofer signal, and where in the car did you make that connection?

Torsen · October 07, 2014, 11:03:03 PM

I think I figured it out. The middle plug on the amp has all the positive and negative wires that connect to the speakers. I should just connect my Audiocontrol LC2i to the front door woofer outputs, as these are the most full spectrum speakers in the car.
