Yesterday (SA 4-9-05), I called my friend who works at the local Guitar Center. I told him I had $4,000.00 to spend on some small FOH gear. I didn't think he could do or that it would even be possible to get what I got for exactly $4,000.00. But he's our band's full time sound guy , so we get the same discount he gets or something like that...
Here's what I got :
two JBL MP415's (used , and in perfect condition) - $800.00

two JBL MP418's (one cost $625.00 , & one cost $566.04 - he had to do it that way to keep this all under $4,000.00 - $1,225.00

two QSC RMX 2450 amps -$1,050.00

DBX Driverack -$450.00

Behringer ECM8000 reference mic -$0.00

two 25' speakon to bananna cables -$0.00

two 50' speakon to speakon cables -$0.00

Road Ready 12 space rack -$175.00

Road Ready caster kit -$77.57

two On Stage sub shaft poles -$29.98
$3999.98
I would have much rather have went with Yorkville gear but money was a concern and I had to make my move before something in the house or something with the cars break down...
But see , I've always used powered speakers for everything I've ever doen. And matching amps to speakers isn't something I'm ever good with or understand. So my question is , did I buy the right QSC RMX amps? The M-PRO's are rated in peak watts and I don't that's the same as program - right?
If I messed up a bit with the amps I can take them back and switch them for something else. I appreciate (eye kant spel) any input...

The QSC 2450 amp will work just fine to drive the JBL MP415's, and the JBL 418 subs have their own amp built in.

It sounds like he got the unpowered 418's. The 2450's will be perfect for your setup. The 415's are rated at 350W@8ohms and the 418's are 600W@4ohms. You'll be add 500w and 750w respectively which is fine. The 418's use the same driver as the old SR series 18" sub and it was rated at 1200w. This JBL setup will take a lot more than what it's rated for. I am running WAY more power using almost the exact same setup as you except for a RMX1450 (900w) each for the 415's and a CE2000 (1950w) each for the 418's. I also have a DRPA and have the limiter set so that the system NEVER clips. Never had a problem. That is a perfect system to get you by until you start doing larger gigs and sounds great for the money. It's a little short as far as the subs go for larger gigs. I am looking into building a pair of Tuba 30's to use in place of the 418's for larger gigs. Good luck!
