i have 3 alpine typre r 12s and i want to build a ported box and the shops are too expensive need some help i want to start it this weekend
Its almost my bed time, I'm really old. You know this box will need to be 40-inches wide in order to fit three woofers side by side, right? So we know that it has to be 40-inches wide and at least 14-inches tall. And somewhere around 18-inches deep. So if you plan on putting this in a Honda Accord, it won't fit. So are these measurements OK, if so I'll work on it tomorrow.
Your thinking is exactly right. The Alpine Speakers are designed to work well in most enclosures. So your specs would be GREAT
