I have just finished 2 Kaiju’s which I am converting to monoblocks and I am ready to start my beepre2. In that I have a sub woofer I was waiting for the upgrades however they are not available yet. Question should I build the beepre and then add the upgrades once they are available or should I wait. I haven’t dealt with upgrades before and don’t want to have to do a major tear down once they are available. Also is there an estimated time when the upgrades will be available?
