Subwoofer is very quiet

Try disconnecting one of the coils and see what happens.

it might also be polarity/phase. I remember I had to wire my tweeters backwards to prevent bass to go through.

This is just a thought

I’ll try this when I get home. Do you think that if the sub isn’t fully mounted in yet and there’s a hole in my sub box because it’s not ready yet, that it messes up the sound of the sub?

I’ll check this

The speaker wires are correct on the sub itself but might be reversed in the inside sub terminal and outside the sub terminal to amp... Maybe

I did this once also, both rear speakers wired to my LOC but left side speaker wire to LOC was backwards and it cause my amplifier to cancel out 51-47 Hz. Drove me crazy for months, lol

 

[Emanuel Rodriguez]

The thing is I already tried reversing the polarities on both the subwoofer and the amp and it didn’t really change anything

What is the output level set at in your head unit for the sub channel. Range is -24 to +6.

I have it set to 0. I didn’t want to mess with it a lot

Might be some confusion, so your friends enclosure is self powered and 300 RMS ? Ported or Sealed ?

And your issue is that yours is not as loud ?

So output is your concern and not muffled?
Might need a different enclosure, it might be canceling out sound waves by poor design.

Can spare anymore room for a larger enclosure?

Might also need to break in the subwoofer.

Yes my bro the subwoofer is an active subwoofer that uses 300 rms and his sounds more cleaner and less drowned out. My neighbor helped me out and gave me some new rca cables which helped a little bit. I need to have my subwoofer output to +5 so that it will work. I can only really hear it when I have my stereo at almost full volume. When the volume is low I can’t hear it.

A hole in the sub box? Yeah that can cause problems.

That's fine. I just wanted to be sure it didn't accidentally get set far negative. You could bump it up to 6 though just to see if it makes any difference at all.

It was just a hole for me to screw in the terminals. After I changed the rca cables and I completely sealed the box it now sounds good.

Holes in subwoofer enclosures cause cancelation (unless it's a port). That was most likely the source of your grief.

You have the option to line the inside of the enclosure with pollyfill also. It will give you a little more sound on the low end.
