hey guys i was wondering if i connect (4) 4ohms speakers on my amp wired in series will my sound Quality decrease or increase, will it be that loud? I want to power 2 speakers per channel for a 2 channel amplifier. Also how do i set the input gains for the soundstream Mpq-6O equalizer. thanks

4 speakers wired in series will yield a 16 ohm load. Your amp will probably not produce much power into that configuration. If your amp is capable of a 4 ohm mono load, (same as 2 ohm stereo) The following diagram will probably be your best bet. Option 2 (series/parallel) = 4 ohm load
Two pair of speakers, each pair wired in series, then wired in parallel
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono |

oh ok thank for the diagram. but what i wanted to do right is to connect 2 4ohm speakers in series to one channel of the amp will this reduce sound quality or increase sound qaulity will it make my system louder?

That would have the amp running into an 8 ohm stereo load. Which is the exact same thing as a 16 ohm mono load. It will produce only half of it's 4 ohm stereo rated power.

The higher impedance will cause the amp to run with a lower THD, and a higher damping factor, "improving" the sound. Will you hear the difference? Possibly, over running them in parallel.
I, myself, run as high an impedance as possible, (generally speaking) for these very reasons. Can I hear the difference? There are times, when, yes, I can hear the difference. Properly and well recorded female vocals are VERY susceptible to THD distortions, and being as one of my favorite overall demo tracks is a female vocal with exceptional recording techniques, it is definitely audible.
99.99+% of the time, it's not likely you or anybody else would notice, though.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
