OK. Now that I've hit the PE sales fo ran amp, driver, and Precision Port, I have somequestions that I have not seen addressed here or anywhere else regarding subwoofer cnstruction. 1. Is it better to put the port in the back or in the front? Why? If it is in the back, how far from the wall does the back need to be? 2. I fitted the Precision Port without glue and can not get all the pieces apart to glue them. Will this be a problem? 3. What size drill bit should I use to drill the holes for the screws that came with the driver and amp? 4. I noticed that most pics and plans using MDF bracing have 4” holes drill in the braces. Is there some reason for that size of hole? Would different size holes in the bracing work as well? I was thinking of gettint the widest spade bit I could find and having at it. 5. Is there a way to hold the sides that are being glued together without clamps? (I don’t have any) 6. The wires coming from my amp are too short to reach the speaker if I put the amp in the back. The wires terminate in a flat female plug that is about a quarter inch wide. I have the PE 500 watt amp. The driver (Quatro 15 has terminals that would accept bare wire. What is the best way to get wires that are about 18” long with the corresponding male plug on one end and bare wire on the other. I have a crimping tool. These are all I can think of now. Thanks in advance for your insights.
