you mean your bass boost? Leave that **** off.
Only use head unit pre-out voltage strength via subwoofer level and overall head unit volume. Do not touch setting such as loudness, bass boost or bass frequencies in the EQ section on the head unit and do not touch bass boost on the amp. Its very dangerous to do so.
Because:
A sine wave form is pure and has all the information(basslines) in the song thats recorded into it. What bass boost does is trying to add extra bass, generally a 45hz frequency that was not there in the song in the first place this results in major distortion in the sine wave.

I bet you have your head unit settings all wrong.
Tell me your head unit settings and use this format => Current setting / max it can go
So for EX. Head unit volume: 27(current)/62(max)
Head unit volume

How is your sub wired? Is it DVC by chance because if so, might be wired out of phase.

The sub is wired at 1 ohm. It's a sq hdc3 12. My volume goes to 40 but I can only go about 23 because of factory 6x9's. I have eq flat, bass boost off, loudness off, but my sub level is at zero because I thought that might hurt.

It's 2 ohm dvc

Okay there's your problem buddy. Volume needs to be much higher, around 32 or so. Sub level needs to be maxed out. A sub level is nothing like a bass boost, it determines how strong the pre-out signal going to your amp is. Thats how you actually get the proper pre-out voltage coming from your head unit. Also the reason why your gain is too damn high.
So max out sub level.
Fk the factory 6x9s (disconnect em or something and raise up that head unit volume. Then reset your gains again.

Do you have a pioneer head unit? If so, your bass level can go to +6. Set it to that and then set your gain. If you have an alpine unit, leave your bass level at 0.
Regardless of headunit, leave your amp bass boost off.

that would really depend on what alpine head unit. Some test clean up to +10 or +15 on the sub level. The amp gain settings on those setups are ridiculously low.

Yeah true, I was just giving from my experience. Pioneer units I always set the sub level to +6 and then set my gain or else I get "no bass" and the same symptoms that the op described.

I have a pioneer hu. I turned sub level to 6. I guess I need new 6.5's they don't like it

Should I turn down highs on eq so I can turn volume up higher?

yes use the EQ to turn down the mid to upper frequencies
How is turning up the sub level affecting the speakers?
Do you mean you turned up the volume? Notice any difference?

The volume messes w the 6.5's. I've has 6x9 hit harder than this system. So disappointed!
