Great progress so far brother The outside looks 1,000,000 times better too!

It depends on whether it's a remote gain or bast boost knob. If it's a bass boost then definitely forget it, but if it's a remote gain knob then it does have a very useful function. If it's a remote gain you'll want to turn it all the way up and then set the gain on the amp like 1two3 explained. Listen for clipping/distortion then back it off a hair. Then you can use the remote gain knob to turn the sub down to blend better with the rest of your speakers but when you want to bump hard or show off you can turn the bass knob up to get more output without having to worry as much about clipping the sub. Trust us, there's no need for any meters or scopes and DEFINITELY no use for a DD-1. Your ears are the best tuning tool. What kind of enclosure are you putting the sub in? If you're putting it in a ported enclosure I'll need to cover how to set the SSF (Sub-Sonic Filter) as well.

Yes cut the ends off and use the smaller holes.
