Welcome to DIYaudio.

You'll find many threads and projects on subwoofers and chip-amps like the LM3886. I'm going to move you to the subwoofer forum so you get some better exposure.

Enjoy!

What we need is to know the parameters of the speaker. At a minimum we need Vas, Qts, Fs, Xmax and power handling. Without these no one can help you.
