TDA7492 bass boost

I got myself this little amplifier to power these pair of speakers. Everything works fine and the audio quality and loudness is perty decent, but the bass is verry low. Is there a way to improve/amplify the bass of the pre amplified audio signal (because i am going to use the bluetooth function of the board) ?
 
Have you checked that both speakers are in phase? If they are out of phase they will produce little bass.

If they are in phase and you still have little bass you can try an equalizer on your phone (If that is what u use as source).

Also, those speakers need an enclosure. Without an enclosure there will be little bass...
 
You can tear up the receiver from the amplifier and put a tone circuit between it (can be complicated) or you can use a boost or equalizer on the device you are using to play the music with. There are tons of EQ apps etc. but I really doubt that's the problem.

What kind of enclosure do you have? How big?
 
I have uploadet some pictures of the enclosure to imgur. I think the problem wasnt the amplifier, the problem was the poor quality of my mp3's. I have also cranked up the gain switch from 21.6db to 31.1 db and lowerd the volume on my phone. Now i got a pretty decent bass and can go even louder. The enclosure isnt finished yet, i need to drill a hole for the switch and rearange the cables a bit.

Thanks for your help.
 
That explains a lot. Another issue is, it's a mobile box, outside you'll lose a lot of bass because there's no room gain. To get a better midrange, you should probably use acoustical foam on the walls of the enclosure.
