Hello,
Just received my Alpine MRV F545 amp and had it installed, powering fronts highs and and a sub. I noticed that the amp doenst even have independent output gain, how am i soppose to tune this thing.
This thing doesnt even sound like a 125 rms amp,
Any suggestion on what went wrong
Also, it said to adjust input level to match head unit. How do i get the head unit voltage? I am using stock head unit with a high level converter.

thanks

 

Stock head unit for what car? Using a LOC? Measure it with a voltmeter. The amp has gain adjustments.

 

You have to remove the 2 little screws holding the silver V12 plate down. There's a tool a that comes with the amp to do so. Once you take that off all your digital controls are found there.

 

Thanks,
yea i took that cover off but it only have input gain not output gain. I thought that input gain refers to the voltage level off the RCA, and output gain refers to the actual volume of the amp?
can anyone clear this for me.
thanks, but the way, it for accord auro r, so close to TSX, and im using a converted with non adjustable gains.

thanks
