jbl power valve amps are additive lol
I have
a bp300.1
2 bp1200.1's
and when I receive the bp600.1 that will make #4
then I'll start looking for a bp80.4 and a bp80.2
Sh1t. I'm guessing you picked up that JBL 300.1 from 2NYCE. 
I have a little JBL PowerValve collection going too. 1 JBL 1200.1, 1 JBL 80.2, 1 JBL 80.4, 1 JBL 180.2.
I couldn't snatch that 300.1 from you, could I?
