What settings for my Alpine 4 channel and Alpine Mono?

[Hoyta 10+ year member]

Hello all!

I'm no sure of the complete specs on my amps, but one is a 75 x 4 alpine and a 300/1 alpine. I have MB quart reference components in the front, and MB quart reference coaxials in the rear(Old German ones). The sub is a shallow mount MB Quart 12" reference series (New Maxxsonics)

I have an older Kenwood head unit as well....

I'd like to know the best way to control the settings on these amps- The gain, the Bass EQ, and the LPass filter on the mono.

Hopefully these aren't foolish questions!

Thanks in advance for your help!

For the mono, set bass at default position. Set gain to preouts voltage. Considering its an older HU, im going to assume that its between 1 and 2 volt. Check to be sure, but if thats the case, then right about 2 oclock setting is fine. LP filter, id say around 80, but thats all about preference. People typically go anywhere from 60-100 on that
