I was wondering is it possible to run 4 8ohm speakers in a Crown xls1000 power amp? if you ran each channel as bridge so the load would be 4ohms per side running total at 2 ohms. is this possible?

Crown XLS1000 and PA SYSTEM HELP!

Thats kinda what I though
Minimum Guaranteed Power per channel, both channels driven: 550W, Stereo, 2 Ohms (per ch.); 350W, Stereo, 4 Ohms (per ch.); 215W, Stereo, 8 Ohms (per ch.); 700W, Bridge-Mono, 8 Ohms;
1100W, Bridge-Mono, 4 Ohms;
Load Impedance: 2 to 8 Ohm per channel in Stereo; 4 to 8 Ohm in Bridge Mono
Would it be possible to run parallel?

The Deal is my band has book several open houses and a few outside gigs, and need to figure out a new PA system set up. we have a 12 channel unpowered mixer, 6 8ohm speakers. and soon 2 crown xls1000's. the idea was to have 4 mains and 2 monitors. and suggestions on how to set this up?
are all the speakers identical? IMO, the XLS1000 might be fine running 2 monitor speakers on a single mix (bridge mono at a 4 ohm load), but you are seriously underpowered out front with the XLS1000 powering 4 cabs at 8 ohms each (safely, 2 cabs per channel for a 4 ohm load on each side).
What model/make are the speakers? I'd go for a higher powered amp for the mains speakers. In fact, you might be better off with 2 better quality mains speakers (instead of 4 speakers) and a slightly higher power mains amp in bridge mono, if you can deal with your mains being in mono instead of stereo. With PA, you gets what you pays for, and it's rare that you have too much clean power for most any speaker system. Another option is to forget about passive cabs and discrete amps altogether and get 4 identical good quality powered (active) speaker systems. A lot less to fuss with. I'm guessing budget is an issue?

they are all in pairs. we have some off brand speakers that run at 300watt continuous, 2 sets behringer somethings both are different, one came with a PMP 2000 and the others one of the guys in the band had. We might be able to get our hands on JBL125s but that hasnt been confirmed yet.
Budget is an issue. This system only needs to get us through a few shows. After summer if we end up doing more DIY shows instead of venues we will be getting a better PA set up. We have a building that sits vacant that we are allowed to use for free to do our own shows.
As of right now we would just be using the system for Vocals, 2 singers and 1 screamer. our back line consists of a sansamp rib running it a crown xls1500 to a ampeg 810, a Valve King and 410 and a 6505+ into a 410, so there is stuff to compete with. We also do Acoustic shows so want a rig that can do that too.

You need to swap out the XLS1500 in the bass rig with one of the 1000's
Right that was an option I was looking at. but still the issue is how do I run this set up?
First off - you need a subwoofer(or two) in the future.
I would use one of the 1000's in your bass rig, run the 1500 in stereo (or parallel dual mono) with two of the best speakers on each side for mains (so 4 ohm load per side). I'd just run two monitors on one side of the other XLS1000 (so again a 4 ohm load), that should be plenty for vocals. Or if you really think you need it bridge it into the 4 ohm load as stated above.

That's exactly what I would do...best advice so far.
If you do get around to upgrading the whole system I would be inclined to keep the Crown amps you already have and replace the speakers. A good speaker setup gives you more bang per buck IMHO than simply spending money on bigger amps. Remember, you don't hear watts you hear sound pressure level (SPL) so a really efficient speaker will make the most of whatever amps you have. If you are moderately handy and can trust yourself to build a box, check out some of the Bill Fitzmaurice designs, they're horn loaded which gives them really high sensitivity.
