Look under "Downloads" tab at bottom for owners manual info. In a nutshell...mic to mixer channel #1, mixer connected to power amplifier, amplifier connected to speakers. Start with zero volumes on all equipment, bring up amps 1st (1/2 volume) and then adjust mixer until sound is heard from the microphone.

Two things... Use BALANCED LINES, either XLR or TRS... AND power the mixer from the same receptacle or power conditioner as the speakers and the sub.

First of all confirm if the speaker impedance is not lower then the recommended Ohms at the back of the Mixer speaker socket.You can use an 8 Ohms speaker on a 4 Ohms amplifier but not vise versa .
Next see if the fan on the mixer works. If not the Amp is getting very hot and this will lead to unwanted distortion. You can confirm if its a heat related issue by playing the mixer at low volumes for more than an hour and see if it distorts.

You are NOT trying to drive speakers from the aux outputs are you? These are LINE outputs that should be using TRS balanced lines to either powered speakers or amplifiers. Often these are used for monitors. The monitoors MUST be powered versions or use external amplifier if the speakers are passive..

Generally speaking you should only send low frequencies to subs. The highs, while lower in power than the lows, will over time harm the voice coils. The ideal way to do this is to use an external crossover netween the main output and the amp input with the higher range going to a general set of speakers. Send the lows through the second channel of the amp and then to the subs.

In short, while not recommended, yes you can hook them up in parallel.

In case you don't have one, here is a link to the manual:http://www.peavey.com/assets/literature/manuals/80300573.pdf I don't know if you are using a separate crossover between the mixer and the amp but here is the simplest explanation.I just reread your question and I don't even know whether you have a Peavey amp. Run proper cables from the main output of your mixer to the main inputs of your power amp.They will be 1/4"shielded cables or Balanced XLR cables. Do not use unshielded speaker cables to hook the mixer and the amp together.Run speaker cables from the speaker outputs of the amp to the input jacks of your speakers.Make sure the impedance of your speaker cabinets equals or exceeds the impedance rating marked on your amp. Here is the link to the newer model PV2600 manual:http://www.sweetwater.com/store/media/pv2600_doc_manual.pdf Don't use Speakon cables unless your speaker cabinets are equipped with Speakon input jacks. Banana plugs aren't as solid a connection as the binding posts are.

use 1/4 inch speaker cables. hook one speaker up to "main 1 R" out and the other to "main 1 L" out. if you have additional main speakers, hook them up the the "main 2" outputs.

look for the "bridge amp mode" switch and move it to the "main L- main R" position.

You can add extra amps driving ADDITIONAL speakers... you CANNOT parallel amps driving the same speakers.

Drive these seperate amps from the MAINS OUT connnectors using TRS and balanced lines to those external amps.

Troubleshooting is always a "process of elimination." Have you tried hooking up your Peavey powered mixer to another set of speakers? How about connecting the speakers to another audio system? Your term "very little sound" could mean audio input problems, mixer/amp settings or failure and possibly speaker damage (internal passive crossovers). Please be more specific.

that depends on your speakers, not the mixer. the amp should be matched to the speakers, in watts and in ohmage. for example, 400 watt, 8 ohm speakers should get an amp that runs at 350-500 watts at 8 ohms.
