Okay, I'm looking into buying a head and cabinet. I'm a beginner and I don't have much experience with them. I've always used combos but I feel the need. To step up my game and equipment. At this time, I don't want a DI box. I want an amp and cabinet. These are the amps that I'm looking at currently. x Behringer Ultrabass BXL3000H Bass Amp Head. Behringer Ultrabass BX 4500H Bass Amp Head TC, Electronics BQ 500 TC Electronics BQ250 TC Electronics BH 250 Then I am going to get a 2x10 Most likely a, Behringer BA 2x10 500 watt And. Behringer Ultrabass BA 115 600-watt I'm also considering a 4x10 to combine with the 15. I don't know a lot about Class D amplifiers. Or even what that means. I want something that I'll have for a while and is going to last. The 2 Behringer's amps are used though I can get a 3000 new for 199. What are Ya'lls thoughts. I think the TC electronics are a pretty good idea. They also have an 800-watt model. Which is a little outside what I am budgeting. I've noticed on the back of some cabinets they have two 1/4-inch jacks. Some have a red on one and black ring on other. Is that a cross over. And if stacking them like the TC electronics only have 1 speaker output. So, do all cabinets have the ability to daisy-chain one too the next?
