Okay, I'm thinking of building a sealed 300L sonotube with 2 AV-15's. I'm wondering about the best way to power this thing. I already have a 350w plate amp so I could buy one more and use 350w at 4ohms for each driver. Then I could take the sub out of the receiver and go into 1 plate amp and then hook the line out into the line in on the next plate amp. Or I could ome off my sub with a splitter and have one go to each plate amp. Which do you think would perform better. I could also buy a RMX1450 and run 450watt at 4 ohms in each driver. Or should I bridge the amp at 900 watts and into an 8 ohm load? What would you guys do?
