Help required for a Hi-Fi numpty please.

We have converted an old Steading(Barn) it's 10m x 3m and I've fitted into the ceiling 4 Visaton DL 18/2 T, 8 Ohm - 6.5" speakers.
The room only needs background music, and occasionally just a bit more oomph for the occasional party.
The music source will be an iPod, so I know I'll need a connector for that. Money is tight, £100 max. I'm not after super loudness or ultra high quality, and I've been looking at some some used Amps on eBbay. I want to power all 4 speakers simultaneously. I've seen plenty of Amps that have inputs for 2 sets of speakers, A + B, but my question is, do these all have the function of powering speakers A and B together, or is it just A or B?.

Any help and advice much appreciated

Just about any HiFi amp will work. Even if it just has one set of stereo speaker outs you will be able to wire a pair of speakers on each out, in parallel this will give you 4 ohms per side which is fine.

Have a look on Richer sounds at the Cambridge Audio stuff something like this will do

Or better still, employ a passive Hafler network. Any stereo amp will do.

Right then....

I now have an amplifier - An Accoustic Solutions SP103, 40+40W RMS @ 4 Ohms.
I have 4 X 8 Ohm Speakers, and want to fit 2 per channel.

Con someone just confirm that I need to wire them in Parallel NOT serial

Parallel - the best thing to do is simply run two sets of cables from each terminal on the back of the amplifier, unless it has dual speaker terminals.

Cheers Zod - I have pre-wired the speakers through the loft, so I have 8 wires coming out through a hole in the wall. So your saying just connect 2 wires to each speaker terminal? (2 to + 've and 2 to - 've} Hope so, that will save me climbing up into the loft again smile

Yes.
