Featured Tuning a salt 500.4

[sounds_explicit]

I am coming from a rockford 600.4 to this salt 500.4 . I'm trying to run for now, 4 prv mr500 neos future will be 8. But the rockford had just normal setting for hp/lp/full. And gain for each channels and a dial for each channel to tune the frequency. This salt 4 channel has all that plus a subsonic that is on the left of the amp and a low pass filter setting that is located on the right of the settings on the amp. I'm confused as to what I'd need to set for these 6.5s. All the extra settings have me a little confused and feeling like a noob. But this is first class d 4channel so if they all have these settings I'm new to all the extra. Any help. Thanks.

I guess what I'm asking is when I run 4 6.5 off this amp I obviously set it to hpf on the x over and then gain and hpf settings. But do i set or mess with the subsonic filter in between the gain and the hpf and the low pass filter that is located on the right? I would assume since I set it to hpf on the x over setting that the low pass filter on the right wouldn't be utilized then? If so.. what do I do with the subsonic lol? Like is that a setting that is utilized when you have the x over set to lpf? I'm trying to run 4 prv mr 500 neos atm. Will be going to 8 later but that what I'll be running off this amp for now. So im confused as to if I use the subsonic at all and low pass filter.

So going fully active, no eq or DSP, 3-way up front? 80-500 for the 6.5"a Just a guess?

Well the hu has a 13 band eq. But I set it flat. Not sure if I'd need a dsp since I have a kenwood with time alignment 13 band eq etc I can set each speaker freq preference but it's not perfect so maybe a dsp in the future would be better. Atm i have 2.75 mr in dash and doors have 4 mr 500 neos in them.

Okay, let's assume you are going what is pretty common. 80-500 in the door 6.5's. The crossovers can be manipulated for whatever you want down the road. Personally, If you can do all the x-overs prior to amplification, that is best. Not many HU's have that ability for a 3-way setup. If yours does, that is what Iwould do and run all channels on the amp full or bypass. If using the amps x-overs, and back to assuming that the HU is flat and full pass out to the amp and 80-500hz is the goal set the x-vers for all 4 channels accordingly:

Set the LP on x1 to 500 hz, and the HP x1 to 80 hz for all four. The subsonic filters all the way down to 10 as setting the HP filter to 80 hz negates the subsonic filter anyway, not a factor. If you move the LP frequency past 500 then you need to trigger that ability by moving the LP switch from X1 to X10 accordingly.

Think I understand a bit but these speakers i got need to he crossed at 220. So would I set my hp to 220 and my lp to 500?

Key to remember is that LP passes anything "lower than" the selected frequency and HP allows anything "higher than" to pass the selected frequency, What driver in your setup wants to be crossed at 220? A bandpass (what were attempting to do) allows for a specific frequency band to pass between the HP and LP frequencies selected.

Prv 6midrange500 neos . says rec crossover 220 so I have 4 of those atm. I also have 4 prv 6.5 mb forte series also 500 watts those say about 95 to be crossed over however I don't have the 4 mid bass forte speakers in yet
That's when I get pods.

Currently tuned to this. It sound OK. I have it set right at 40 volts on the gain It started to clip at 50 volts to I just backed it down a decent amount so I can try and set the crossovers. It's pretty loud. I don't really hear much of anything bad. Bad sounds clipping distortion. Just really loud and pretty clear. I don't have a way to tune the freq Soni kind of eyeballed it and lowered the power a bit. I have a dd1+ thinking about grabbing a cc1 to set the freq

So were talking about midrange speakers not midbass. how, what are you going to do for the 80- 220 frequency bands? Important sound there, virtually all of the midbass which neither of these drivers are really good for. To answer the other question, yes, chang the HP to 220 will cross them at 220. You are going to need to change to LP too. I assume you plan on running the these mids to around 4.5 to 5k? If so then change the LP multiplier from 1X to X10 an multiply the markers by ten (50 is 500, 500 is 5k, etc.) to set it accordingly.

I have 4 prv forte mid bass speakers waiting for pods.

The 3db down point on the Forte is around 180hz. It's still a midragne and not a midbass driver. Loud, just not low. And no higher than 24 db at 3k preferably 2.5k. It's 9db down at 90 hz, which is half as loud to the ear as it willbe at 200 hz.

And depending on the size of the pods, that could be even worse.

Well i may just say f it and grab 4 more mr500 neos then. I'm not looking for a lot of low end mid bass really just some thump that's gunna be obviously lower then the prv mr's . I currently have 3 x 15s dual .7 ohm on a salt 8. So the bass is so much that I know really adding a dedicated mid bass wouldn't really do to much whennibstart cranking on the knob. It will get drounded out pretty quick but for those times that I just cruise a bit with the bass down I can't really stand the sound of just the mid ranges. Currently I have then crossed at about 350 for the hp and about 11k for the lp. Would you think adding a mid bass would justify me spending any more in this? Even if it wasted hp crossed at 80 but let's say maybe 100 ?
