How much audio quality is there at 40hz?
It won't blow up will it?

Probably won't blow up. The DC300A was spec'ed for 2 ohms. May not sound great.
Your neighbors called. They like your music.
So, wired everything up through the crossover, man what a bunch of wires and knobs... the preamp amp and crossover have no manual, so I am flying blind. The only way I can figure out how to wire it all up, I am sending the full signal through the tape loop on the preamp, to the EQ so that sound is what I want through the Altecs, then sending that to the crossover and to the three amps and to the Alpine subs, 418-8H II, 808-8As and Piezoes. I think that to send flat to the subs, and EQ'ed to the Altecs will require two EQ's. Any advise? At 1000hz, the Altecs have never sounded better. Too bad I have to jump up every other second to tweak this stuff, I guess I don't have to get onto the wife's treadmill anytime soon.
PS; after opening up the second Altec speaker, I found a tag that says that the compression drivers are actually 808-8A(802-8D) drivers that have newer Pascalite diaphragms.
Playing a little Weather Report, Return to Forever, Yes, Styx, and even Michael Jackson for the Wifey, and I love it. Can't wait to get a full 300 wpc to the subs.

Google for the other gear. You may find downloadable manuals for them.

Thanks for the links Mah. No Soundcraftsmen manuals, but the Crown was informative. I found out I can mono bridge it with a couple of internal jumper wires and a resistor or capacitor (can't remember, but won't try it nor running it at 2 ohms).
For fun I spent about 5 hours and went through every crown amp on Ebay and looked up each in the crown obsolete section webpage. It was interesting, but I can't make heads nor tails from it or figure out which would be a worthwhile amp to seek out. I also notice that there appears to be no rhyme or reason for the names, lettering, or numbering of their amps. Looking at the prices everyone wants for used-up gear, and having never bid on anything on ebay before, I think that the Parts Express Crown XLS 1500 that was on sale in December for $350 sounds like the best bet for a sub amp.

Yamaha make good PA amplifiers. I use a Yamaha XP1000 for the 416Bs and a Nad C-326BEE for the 802s.
