Thanks for the tip Bill. Never heard them called water pump pliers before though, always called them channel locks, not even my dad called them that and he was a mechanic in the navy during Vietnam and then for the post office.
Anyways, more progress. Got panel ten and the braces left to put together. Cabinet should be assembled by Saturday. Will still need to make the stand, going to have this down firing, partly because that's what I prefer and partly because if I have the horn mouth up I know at some point my cat will end up stuck in the horn and I wouldn't want that to happen.
Still gotta figure out how I'm gonna break in the driver, only way I have to send the tone to the driver is to disconnect a speaker(yea I gotta get more speaker wire), use the wire to connect to the sub amp, unplug my current sub to use that rca cable, headphone out on my phone into auxiliary input on my receiver. And since my phone updated, it cuts the volume if you leave it on max for an hour or so warning you about hearing loss.

And the only way to get the ten volts is to have the volume higher than it will run without a warning popping up. I ran into because a podcast I listen to regularly with headphones is often low on the record level and I have to turn it up to hear it at a normal level. As a sidenote, not sure exactly how accurate it is but the most I can get is about 90 db on my headphones plugged into my phone according to my Radioshack DB meter.
