BX63. Finally

[58crewchief]

So I've been running the B380 for the last year or so with a JBL 6290. Fine amp and works well for powering two subs due to the dual mono option switch which takes the single summed mono output from the BX and splits it to two signals for each channel internally without the need to use a lame y-cord but the fan noise of the 6290 is getting a little old. I wouldn't mind a bit more power either...I'm looking at going with either two Crown PS400's bridged for each sub or maybe two JBL 6260's depending on what I can find. The Crown's give me more power but honestly the 300 watts from the 6290 is probably a bit underrated. That looks like it will put me back into a y-cord. It is possible to use both the standard and inverted low freq output on the BX to run each sub and amp with the y-cord? Will it sound stupid?

Nothing wrong with the y cable/splitter. Technically, you could probably do this but you'd have to reverse the speaker wiring connection on 1 of the channels so both subs are operating the same way. You'd have to determine whether normal or inverted is the proper connection with 1 sub, then reverse the other to match the operation of the first. Easier to use a splitter or y cable on the crossover output. I use something like this: https://www.crutchfield.com/S-31sMns...iABEgLHXvD_BwE

I'm personally not a huge fan of bridging amplifiers as it tends to add noise, but I appreciate the need for more power.

I'm late to this party by several years, but I recommend Crown K1's or K2's. I had access to two K1's, so that's what I'm running. I am bridging them, which results in 1000 watts or so. I've only seen clip lights on them once, and that was me in the early process of tuning my BX63A to get the relation between it and my mains right. The K series do not use fans and allow a person to daisy chain amplifiers like your JBL amp, but I'm using a Y-splitter.There's another recent thread here, I think covering JBL M2's or the like. A member recommended a relatively affordable stereo Crown amp for bass duties. I forget which model it was, but it boasted something like 1000 watts per channel. Trouble is, it has a fan. Although I think it is off at low levels, so by the time it kicks on, you shouldn't hear it.
