Horn Tweeter

can i connect 4 speakers to just two outputs on a powered mixer?

I have two 18" 1000 watt peak soundlab subs (8 ohm resistance), two 700watt peak soundlab speakers (each with 1x15" driver, 1xmid-horn, and 5xpiezo bullet tweeters, 8 ohm resistance) and I was wondering would i be able to connect all four speakers to the two outputs on a (2x600watt RMS at 4ohms per channel) soundlab powered mixer without breaking/blowing the amp? i thought i could do it by connecting 1 sub and one normal speaker together in series to one output and the other sub and speaker to the other output. would the speakers combine to 16ohms resistance and therfore be quieter? the amp is the soundlab MP12 1200w powered mixer. thanks
its actually for my band, we need a decent sound setup and I have the speakers and was looking at this powered mixer because it is reasonably priced. the only problem is that I have no experience in powered mixers or proper setups.

Try to establish all your power rating in RMS. PMPO is misleading.

Peak Music Power Output (PMPO) (also Peak momentary performance output) is a much more dubious measure, of interest more to advertising copy-writers than to consumers. The term PMPO has never been defined in any standard but it tends most often to be the peak power of every amplifier in a system added together. A 5 channel system using 10 watt amplifiers might be specified as '100 watts PMPO'. Sometimes, an extra factor is applied to get an even higher figure. The term PMPO is greatly despised by audio professionals; it is considered misleading and without purpose. Most systems cannot sustain their PMPO for more than a few seconds, loudspeakers being particularly vulnerable. The voice coil might burn out, or the speaker may actually catch on fire, from the voice coil becoming hot enough to ignite the speaker cone. In other situations, the crossover in the speaker cabinet may fail, including (but not limited to) burnt-out choke coils, exploded electrolytic capacitors, burnt-out resistors, or blown fuses.
