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.

Idea quest is an A** hole.
PMPO stands for peak music power output and is 4 x RMS.
So if something says it is 100 Watts PMPO then it is actually 25 Watts RMS.
A lot of manufacturers who are at the cheaper end of the market use PMPO as a marketing ploy. It is because there amps/speakers have a low power rating and they are just trying to make their product sound better.
Anyway your question.........
I would recommend a channel splitter which would let you connect all four speakers safely to the amp. If you try and connect the two subs to say the left channel and the two speakers to the right channel not only do you run the risk of blowing one or both channels on your amp but your two speakers on the right channel will be mono.
You may want to consider buying a splitter that enables you to run one sub ( since they are mono anyway not a problem )and both speakers. It connects to the back of your amp and your sub and speakers run off of the crossover/splitter. Kenwood used to do one but you would have to look to see if it is still in production
Or like the other guy said buy a two way splitter and connect the two speakers to front left/right and the two subs to rear left/right. Sure it will be quieter but hey it is cheaper than replacing a blown amp.

This wont work. The reistance will drop to 4ohm if you connect both speakers (its like useing two 8cm water pipes instead of one pipe so you get half the resistance. You could damage your amp as it will get very hot.
try looking at a cross over unit that will split the low and high frequency sounds you can then drive your subs seperately from another amp.

car or home?
Dont mix the sub and the speakers together cus that will sound ****!
run the speakers with a splitting block from one channel and hammer the subs off the other.
yes this will reduce the output but its either that or you pay for a new mixer or maybe i saw a kinda speaker control box which would split channel neatly a few years ago
