Marshall DSL100 into 2x12 guitar and 2x15 bass?

Hi all, new to the forums, so thanks for humoring my noobness.

I have had a Marshall JCM2000 DSL100 from new for about 12 years. I'm currently getting it serviced as one of the valves blew but then im hoping it'll be back to fresh!

For the sound I'm after, I play a Fender Bass VI as a normal guitar - our band plays a mix of DFA1979, QOTSA and The Bronx style stuff - Listen to the band here THE MALES.

So speaking to a friend, he advised that I run the amp into my existing 1936 2x12 cab, replacing it's speakers with decent Celestion greenbacks and also out to a 2x15 bass cab. I basically want some serious hi gain crunch, and a decent low end too.

Can anyone advise me on a) which greenbacks i'd need to buy and how I'd wire them (series ? parrallel?) and b) what rating of Bass cab speaker I'd be looking for to match this.

as an optional C) does anyone recommend I try a different head? maybe a 5150 or a Blackstar 100w head?

Thanks for any advice, I'm pretty much new to this.

You may as well try the amp directly into a bass cab and see if you like it or use high wattage (100+watts rating each) speakers in the 1936. The high wattage guitar speakers ( Fane AXA Studio 12L, Electrovoice EVM12L etc) will also give you a tighter low end. Splitting the signal is alot of hassle and you may just prefer having one cab or another. Greenbacks are rated too low for a 100w marshall, don't bother unless you have four of them.

As far as the impedance and wiring goes, it all depends on the bass cab. Most 2x15 bass cabs will have two 8 ohm drivers, which could be wired in series to provide 16 ohms. Usually, for a bass cab, they would be wired parallel, making the cab 4 ohms, which would be problematic. If You got two 8 ohm drivers for the 1936 and wired them in series, You would have another 16 ohm cab. Both cabs running together would present 8 ohms to the head which should be fine.
