Adjusting amp input voltage from head unit

[Stoddamx]

Need clarification on adjusting my voltage for my subwoofer amp. Test tone of 40hz (same I use for setting gains with scope) dmm on rca inputs on amp.. Raise volume until I get the voltage I want.. I need to run around .2-.4v input on my amp.. (Big amp very low impedance)

Let me guess. Your protecting. And its a B2 audio amplifer?

If so, speak with B2 directly. They say something about needing a lower input. Which i dont really get or understand.

If im way off, all aplogies ....Good luck either way.

Yeah it's a B2 M1u. Exactly what you said . Now they are thinking it is loading issues with my subs. Wrong enclosure or something like that.

Lol he's had like 2 or more different threads in the past couple days w/ the same question but asked a little differently.

Ran to M1u's in a buddies build.

We where told something about the headunit voltage needing to be somewhere and somewhere.

We sold them before we ever really dug into it.
