Educating myself with sound system setups has certainly been a bigger challenge then I thought. With that said, someone please tell me if my setup is good or bad.

18" speaker subs. Fane speakers rated at 250 watts@8ohms.
(1) sub per side.

On top of the subs I have Peavey SP-1's. 15" speaker and a decent size radial horn. I believe rated at 150 watts@8ohms.
(1) Sp-1 per side.

I'm using (2) DOD SR835 crossover's in 3-way mono mode.
(1) crossover per side for stereo tri amp configuration.

From my FOH board (Behringer MX3282A) left/right out to DOD dual 31 band EQ. Out of EQ to snake send 100' to the crossovers on stage and then to amps.

I have set the Low/Frequency knob on channel 1 to 150Hz cause I don't really know what Freq the Fanes should have.

Channel 2 on the X-over is set at 600Hz as this is what I see marked on the back of the SP-1's.

I run a line out of the X-over low to one side of a Peavey CS-800 rated at 240 watts@8 Ohms

1 line out of X-over mid to another Peavey CS-800 for low/mid input on the SP-1.

And 1 line out of X-over to a QSC RMX850 rated @ 200 watts@ 8 Ohms to the Hi input of the SP-1.

I do the same for the other side.

Now this seems to work and sound good but, I tend to see the amp for the subs light up red often when I'm pumping bass and kick drum.

Should I just bridge all the amps and have a supply much larger then the demand? Is that safer, smarter or as risky?

I also use some old compressors with inserts and an Alesis Microverb for reverb/delay..... but that has nothing to do with my main power and speaker setup.

I don't really know much about testing speakers for frequency, or wattage.... I'm really a guitarist turned sound dude. Better pay and I don't have to learn junk songs.... but thats another issue.

I appreciate any thoughts on the matter. I know that the speakers and CS-800's are relics but, is all I have for now until the money adds up and I buy better stuff. The Behringer was a great idea I thought for the price....
