Hi Mr. B,<br> <br> I'm very big into the speaker DIY community. Go to my site www.jonbrinkerhoff.com and see some pictures of what I have done. The best prices will be from www.partsexpress.com . The absolute best in sound quality will come from a Morel; #297-012 if you do a search for it in the box at the top of the Parts express home page. With its high Qts, it is well suited for 'free air use' but it is 8 ohms, which would require you to add some separate amps. If yer' looking for a quick fix, just look for 4'ers under car audio. And if you would like to learn more, go to the Tech Talk board at the bottom of the main page. The people there are very knowledgeable and would love to help you. <br> <br> Jon-Michael <br>
