Amp tuning help

[Chief_BigCat]

I have a 2000 Chevy Impala

2 12 Memphis M3

Alpine MRX M100

Ported Box - 38hz 35in x 15.25in x 14.25in

I've tuned it many different ways and I am not really sure the best way of tuning it now with my ported box, I would love some help.

Looking for as loud as possible, kind of the reason why I am posting in the SPL.

Thanks for the help

What do you mean by tuning? Low Pass tuning? Gain Tuning? Please Elaborate

[Chief_BigCat]

Low Pass and Subsonic mostly, gain if you are feeling helpful, just an all around change, as of late I have been running heavy gain and light on the low and subsonic and no bass eq

[Avery Howell]

For gain you're gonna wanna get a SMD DD-1 or an O-Scope. Not quite sure on sub-sonic, and what is your box tuned to?

[Chief_BigCat]

38 hz

Oh it totally says that in your original post, whoops sorry. Usually its whatever sounds good to you, but a starting point would be around 80 for the LPF.

the gain isnt a volume knob. really should get that set right. look for the smd tool map on this forum. you should be able to find someone near you that has one.

dont use bass boost, lpf should be at around 60-80hz. ive read that the subsonic should be about 10hz lower then tuning freq of the box.
