This is my understanding and I maybe wrong, please correct me if I'm wrong! Now, bass amps are usually 250 watts, 500 watts, ect., but power amps, usually used to power PA systems for live sound are 1000 watts, 6000 watts and better. Since we bass players need a lot of power to be heard, and felt, we tend to go to power amps for more head room and sheer power! I'm I right s far? This is a power amp, right? 1600W/ch @ 2 ohms, 1200W/ch @ 4 ohms, 650W/ch @ 8 ohms, 3200W bridged mono @ 4 ohms, 2400W bridged mono @ 8 ohms. <----I have no idea what this means but that's this power amp's stats. But as a bass player, I can't just hook my bass into this and some speakers (I'm not sure why, somebody help me on this). I need a pre amp because the power amp and pre amp are not in the same package like regular bass amps, right? So now I have to get this.... This is some sort of pre amp! The only thing I can find are microphone pre amps, I'm not sure if you can use mic preamps for instruments but I believe a pre amp and power amp is needed. Now remember, I'm just trying to put this all together folks so I can understand this thing here! And to protect and house my amp and pre amp, I need to put it in a case similar to this! I hope I'm not looking like a complete idiot here! So for the most part, did I nail this thing here? Oh, one last thing: Now as far as speakers go, do I use regular PA speakers or regular bass cabs?
