[QUOTE="Loren Jones, post: 33376, member: 829"] Re: Sub Amp? 1 large amp or 2 smaller amps. Phil, I didn't build them yet. I was trying to get a realistic idea of amplification cost to pitch the idea to the pastors. I have used two of them in our service once and it seemed like they were getting fairly close to capacity that's why I was thinking 4 would be safer. Newbie volunteer operators like me are much less likely to hurt anything if it is designed with some extra capability / headroom. I think I'm gonna try them again this weekend. I will probably power each off a bridged MA2400 (which we already have 3 of on our current subs) and see how that is. Thanks for bringing some intimate knowledge and math reality to the table. If the pastors ended up buying off on it we could just pick up one more MA2400 and run one bridged into each sub. That would give us similar power to one box per side of a PL380 or one per a bridged RMX2450. That would save a ton on amp costs. We'll see if they will go for it. The question was partly theoretical just to see if there is a reason to prefer one large amp with two 8 ohm cabs per channel vs 2 slightly smaller amps with one cab per channel or even one bridged amp per cab. I guess there is no theoretical advantage for one over the other. 1 big amp is less weight and rack space if you are moving things, but the options with more than one amp give flexibility and redundancy at the cost of weight, space.
