greetings, 
a friend has given me two of these at a great price, and i plan on using them to drive the sub cabinets im building. planning on 4x 18ps100 drivers (700w rms) in b&c sub18 cabinets, and the amps are rated at 1600w @ 4ohm bridged. 
this is my first build, so i have zero experience but i've been doing as much research as i can. is it reasonable to think that i can run 2 drivers in parallel per amp in bridge mode?
i know ideally i'd want more headroom, but i'm trying to work with what i've got. 

cheers

What you are proposing is fine. Bear in mind, you will need two separate 20-A Circuits in order to operate those amplifiers properly, under the given configuration.

right on good to know. the majority of use is going to be using a 6000w generator, which should be capable of producing 40-50amps according to google. 
that'd suffice, no?

7001s like all the old Pro series are great quality, but they are really old now. Those could be pushing 30 years! I would get them tested and serviced as required by a decent engineer before pushing them really hard for sub use.

Yes - the 7001 is a lovely amp, but a packed chassis. At the very least you need to pop out the modules & give them a good cleaning. Dust tends to accumulate around the corners by the fans, which can lead to problems.

according to my buddy they were serviced ~5years ago, and i've popped them open and everything looks great. getting them tested is a great idea, will definitely be doing that before i put any load on them.
