I found that site on the internet also. More confusing than helpful unfortunately. Thanks all the same.

Also, what are you wanting to achieve?

What are your listening preferences? genre?

How much power?

How much available space?

Thanks for that tutorial, that was easy. Now, how do I build a 4 liter box with a 10 foot long, 4" square vent? The box is supposed to be 11" x 7.5" x 5". LOL!

BCAE1.com .....that has everything you need to know anything you want about car audio. Perry Babin (spelling?) is an amazing individual imo for making that site and I highly suggest you check out the box building section.

Thank you all so much for sticking with me and my ineptness. I can make the box bigger. Would like to keep it as small as possible though. Please share what you can. I will be away this weekend so there is time before I begin. Thanks again!

Power should be 150W @ 4ohms bridged.
Subsonic filter - my amp does have low and high pass adjustments as well as gain, bass and treble for the sub channel.
