is that 158.6 on the old school audiocontrol or on the sensor?

No chicken this is on the new 190 sesor.

if its the truck im thinking of he only gains 0.5dB on that sensor compared to the TL

Yes sir once again you are correct Peter. The vechicle did a 156.9 or a 157.9 on the 190 last year then had nothing but issues wich will all be solved very soon. The score is not to bad from only 2 AB 500.1s see what can happen when you have real batts that float over 11.6v and amps that actually work lol.

If Its The Truck Im Thinking About
He Did A 156.8 On The 190
But Floated Way Higher At 11.90 Volts
And The Amps Sucked Always Shutting Down
Atleast One Amp Every Burp
Hopefully For Him That Will A Go Away
Good Luck

what truck???

franks?
