Subwoofer only hitting lows?

[I_Love_Bass 10+ year member]

I recently purchased a Cerwin Vega 122/124 Stroker 12" sub (older cooler looking model 1200 rms 2400 peak) from a friend of mine used for $200 and it came with a ported box built to spec. For now im running it on a Boss 2000 watt amplifier while i save for a new better one. It SLAMS so hard on the low bass hits on songs. (Grillz, muscle cars, break ya ankles, break em off etc.) but when it comes to higher bass notes (mercy etc.) the bass is like non exsistent. Why is that? I don't know the exact specs of the box but its pretty big looks like 2.0 cubic feet? Its a long box barley could fit in the opening of my 2008 Civic 4dr. It looks to me as a good quality box. Maybe its the amp settings? My input is all the way. (i know its bad, just wanted to see how it would sound) but i didnt mess with anything else. Oh the amp came with a bass knob too.

Oh man, where to start. First, turn your gain down before you blow your subs. What type of box do you have? Do you have a head unit where you can set subwoofer crossover or level? On your amp, what is your LPF set to?

I know i turned it down. And yes on the stock radio you can tune bass,treble,svc, etc. and i think the lpf is untouched so 0. Haven't checked

The low pass filter on your sub amp should be set probably to ~80hz.

You should probably check. May be where your problem lies.

LPF cant be "0". Normally its set at 125hz, 100hz, or 80hz. Whatever it is set at nothing above that frequency will be let through to the speaker.

Lurking. lol

The holidays get kinda crazy for me, hun. I missed ya, tho!!!

Before assuming he should set LPF at 80 lets find out the frequency range the driver supports first and go from there. Especially since he is complaining from top end output and you're telling him to cut it off with a filter...

Might be helpful if you could get some clear pictures of what the settings look like on your amp.

The "~" means approximately...

Sorry i'm new to this, well its not 0. I'll check in a few. Whatever the stock setting is on amps is what its on. So if it is indeed already set to 80hz, what else could be causing them to not hit higher notes?

How does the ~ make any difference? He is complaining of top end output being not enough and you're telling him to filter all top end out after 80hz.

LPF at 80 shouldn't be a problem with the song example he gave (Mercy).

Could be anything from the box to the rest of your settings. If it is set to 80hz, try turning it up slowly and see if you get any response.

Too early to argue with you.
