you also forgot to mention that he would need to do this with a test cd of 60 hz.

Oscopes are the only tool for tuning a system man, otherwise it is like trying to use a screwdriver as a chisel. It will work but...................... The right tool for the job, do it right do it once.

What are the cross-over setting on the amp set at?

 

What do you mean exactly? Gain is @ .5V, LPF is at 100hz and Bass boost is at +6dB.

 

Have you tried turning the bass boost down a bit, then turning up the volume?

And ported box's require more airspace.

 

I was asking if you had the sub running only bass or on a LPF as you said,

What are the bass and loudness settings on the deck set at? Try retuning your amp, but set ALL the equalization to ZERO, adjust the gain and THEN you can play with the bass boost if you want to.

 

Turn the bass boost off completely ("0") and leave it there. Set the "bass" on your head unit to "0" and leave it there. Then set your gain so that the level of the sub blends with the level of your front speakers.

If your sub is bottoming out you will damage it. Turn it down.

 

I totally agree with everyone, turn the bass boost and gains all the way down and turn the volume up to what you can stand, then adjust the gain. Trimming down a box is not a problem, there is a range of airspace for the sub to be "optimal". Porting does require the box to have more air space.

Just turn the boost and gain down.

 

Scott, I have my bass boost maxed out and I'm wondering why my sub sounds like doo doo...


Fink,

If your speakers are powered properly by an amp that has a high pass filter, your fronts and rears should cross somewhere between 50-100 hz.

Bass boost is a distorition machine. Turn it off.

Gain on the amp is relative to the input signal strengh and the capability of the speaker. The only proper way to set it is with an oscope so you can make sure the amp isn't clipping. TTOCS's has told you the truth.

You can set the gain by ear but it is an aquired taste.

You are setting it backwards if you are setting it by ear.

Turn the gain to 0 on the amp and turn the HU to the loudest setting you plan on listening too. Slowly turn the amp gain up until you hear distortion or the sub is to loud for your front stage. Then turn it down a little and call it good. If you cannot hear distortion, you may blow a speaker in the process. Speakers don't like square wave signals...
