You need to now the RMS for a true capacity of your speakers and your amp.

I would say you are OK, with a margin, but if you turn the amp to max and blow the speakers, please dont call me.

Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...

If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.

If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....

Contact the Sunfire tech folks . They've responded quickly for me.
Probably not in the power amp. It's whatever youre plugging the MIC into.

It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system.
If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering.
you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.

as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.

Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it!
Hope this puts you on the right track
Happy Hunting!

What brand is this?

After connecting one, turn on the other. Then while both are powered on? Press and hold the button on both earbuds until they connect to one another.

There are two types of sub. The first is the powered type. This has a socket that connects via a cable to your amp socket - marked sub out. Some amps have the abillty to switch this socket on or off and comtrol the output. The sub itself is mains powered.
The other sub is none powered. This requires the speaker cables to be connected to it, the bass being extracted from them, before passing the signal on to the speakers
