ok I have a pioneer avh p4200dvd hu, I usually set it by ear, this was my first time trying the dmm method, just curious to why its not recommended to use the bass boost, last time I had my amp gain set about halfway and about a quarter of bass boost and that worked out pretty well for me, I will check around for an oscope

my hu was set at 75%, and I had the subsonic at 15Hz just because that is its lowest setting, I changed it once I was done, and telling me the dmm ftl does not answer my question

Ok I have a Hifonics Bxi 2006D. I attempting to set the gains with a DMM. Well I will be running the amp at 1 ohm @ 2000w. So using that formula I got 44.72v so I used a 50Hz test tone from real of excursion, with my low bass set at around 75 or so and bass boost set at 0 and my subsonic set to 15HZ. Well if you look at my gain knob the far left is 9v and the far right is 0.2v. So Im assuming 0.2v is wide open. Well when I used my DMM to achieve the 44.72v my gain know is basically at 3 o'clock which is at about 75%. And my hu has 4v preouts. Just curious does this seem right.

sorry guys i just went out to double check and sure enough it was one

So you are saying that there is an acc wire, but there is no acc position to actually turn the key too, my switch has 3 positions, off, on, run most cars have 4 positions which are the same except with an acc position.

picture was very helpful thanks

my model Tahoe doesnt have an accessory position

thanks, but to make sure that I am following you, can you do like a quick sketch

so u have the switched power source hooked up normal, and then u run a constant hot to the same wire but just leave it off until needed??

For those with aftermarket hu and speakers that are not using any harnesses. I know the RAP powers things for like 10 mins but you lose that without the proper harnesses. So I was wondering how do you guys/gals play your a/v system with the key off since these trucks dont have an acc key position.

the area is on the smaller side but im sure it will be fine, well winisd says it should lol

so you all think this will give better results

it will be 4 subs total, two 12s per side, there are two center walls missing in that pic, but it will be two enclosures

Please explain to me why this will not sound good or how i can fix this if it is a problem trying to tune my box to 33-34Hz, its 3"h x 14"w x and 14"l thru the middle

thanks, that is exactly what I was asking, and my pic was just an example of how the port opening would looking from a frontal view
