1118717 2010-07-26 01:14:00 what about the 200+ miles of cable back to the power station. Not much point ONLY upgrading the last .0001% of cable. ;)

I think you mean a dedicated line inside the house?? But again, its all connected to the same point at the fusebox. No gold plated $400 hifi fuses in the fusebox/meterbox either :thumbs:

I think supply source impedance for transient load peaks is what they are worrying about, but that is usually taken care of by the capacitors in the power supply. Accidentally drop a screwdriver across the mains connection, even at the amplifier end, and you'll soon find out that source impedance is no problem at all.

Re the din plugs, it is not really an up-there Hi Fi system with those for speaker connectors as the contact resistance would be quite high. Din plugs are not rated for high currents anyway. I'd be inclined to pull them out and replace with a couple of two-way connector strips. That will give a lower impedance connection without all the hassles of first trying to source them, then solder to a din plug. They are fiddly little sods and I dislike them intensely.

Jaycar sell them though, if you must.

1118718 2010-07-26 01:26:00 Ummm... don't know of any tutorials, but I'll try and describe here what to do

1) Get a cheap 10m extension cable from Bunnings or somewhere
2) Get some snips/pliers and cut the plugs off either end
3) From t he end of the cord, somehow make a cut (down the length of the cord) into the outside white insulating sheath, and then start pulling it off (you'll need to pull really hard, and the cut you made should continue to rip
4) You should now have 3x 10m wires, so have a think about how you're going to chop them up. If you're careful you can get 2x 7.5m speaker cables (3x10 = 30m total, 2 speakers = 15m per cable, 2 wires per cable = 2x 7.5m cables)
5) You'll now need to solder some wires together in the middle. Remove the plastic from the ends of the wires and solder them together (search Google for a simple soldering tutorial. You'll need a solder iron + solder.)
7) Wrap insulation tape around exposed solder joins
8) Figure out what connections you want on your cables. For example, if your speakers just use spring loaded clips, then you'll just need to remove some of the plastic at the end of the wires to expose the bare copper. If your amp has RCA outputs, then go to Jaycar or Dick Smith and get some RCA connecters.
9) Solder whatever connectors on that you need

Finished :)

Hope that helps a bit. It pays to have a bit of experience stripping wires/soldering, but anyone can do it really..

Geeze, what a painfully slow, wasteful and potentially expensive way to do it! :eek:

Buy some white or grey trurip (twin stranded cable) twice the length you need for one speaker lead.

Strip ends, solder to plug (or throw away the old plug and socket arrangement and use 2 x 2-way connector strips per my previous post) position speakers, connect other ends to amp, switch on, enjoy.

Trurip is polarised by either a trace silver wire in one conductor, or by a ridge moulded into the plastic sheath. Just make sure you wire both speakers the same or you'll get some funny phasing effects.

The amp end probably has screw terminals anyway.

some tend to use a finger for this :lol:

Are the connectors these ?? jaycar sells em, or used to.
