Settings on My Amp?

[donovanl12]

Alright, so I tried setting up my amp settings, but I don't really know what they are, so it doesn't make much sense in my trying to set it up. The amp is a Sound Ordnance M-1350. It puts out 210 watts at 4 ohms and 350 watts at 2 ohms(i know, really low), and I have a single Sundown Audio 8 inch Dual 4 ohm sub. It's getting my sub really hot on the dustcap! Trust me, I wired it correctly, i'm just not good with setting up the amp I guess. I wired the dual 4's down to 2 ohms to my amp.

The settings on my amp are: Bass Boost: 0 db to 12 db. Subsonic Filter: 10 hz to 40hz. Low Pass: 40hz to 300 hz . Lastly, Input Level. 6V to 0.2 V

I understand the first one, pretty easy. I don't get the Subsonic Filter, Low Pass, but I kinda understand Input Level, it's amount of power coming from my battery, but why does it say 0.2 V? shouldn't it be 12 V?

What I'm trying to get at is, is it possible for someone to get me in the right direction to what i'm supposed to put these settings at? It's messing up my sub.

By the way, everything else is wired correctly, I had my dad check it out, and my dad has every certification on cars to Boeing airplanes, electrical, everything, lol.

So if someone could tell me the correct settings for the two settings, that'd be great, but I'd like it so my sub is putting out the most it can safely.

Thank you all so much for helping me get started, this is only my 1st system, I had a different sub, a Single 4 ohm JBL GTO 804, i upgraded to this.

Thanks again,

Don

Put the subsonic to 20hz and the low pass to 80hz

The subsonic filters out low signals that you can't ever hear. The lpf filters out higher notes.

If it's sealed set it down low, but if ported set it pretty close to your box tuning, I like to do it +/- 3. If it is set too low for a ported enclosure it could cause the sub to unload.

Set the subsonic filter to 5hz below your box's tuning if it's ported, set the low pass to 70-80hz, adjust Level with an oscope to make sure your getting clean power. Sounds like your clipping the sub.

That's what I'm worried about...I don't have an oscope. Is that the only way to see if it's clipping?

No, does your amp have a bass knob/ clipping light?

It has a bass knob with a power light, just stays lit. On the amp there is a power light and a protection light.

Have access to a digital multimeter? It can be done with one.
