I've always used purpose built bass amps. Now I'm pretty sure I'll be moving to a preamp/power amp setup. I've been talking to people and getting conflicting info. I'm pretty sure I'm going with the Ampeg SVP Pro preamp/QSC PLX combination. I'm pretty sure I'll be running a Golliath III (2/10 already have) and a Son of Bertha (1/15 or BagEnd S15BD). Let's say both cabs are 8 ohms. Originally I thought the QSC 1602 PLX which puts 350W into each of the cabs would be plenty. Some feel I need to upgrade to the 2402. Anyway, I've also been told by some to bridge the amp. Now if I do that I basically have one big amp and one bigger speaker. Correct? I loose the ability to adjust the level of the 2/10 box and the 1/15 box independently. Correct? I'm not going to add a crossover and the Ampeg pre doesn't have one built it. What is the best way to run such a setup? Thoughts? Thanks.
