      i have a 500w logitech sub and a technics amp, – some vital cables, i got a power cable from the back of my ps2 but i need a cable to go from the controle center on the sub witch looks like an avg on a compter to phono on the amp, i went to maplin and they didnt have a cabe. my friend said i should take the back off the sub and bodge a cable, pepole have alsotold me these things can blow up. is this recomendable?

        if the sub has a power cable going into it then does it not have a built in amp?

            You want to go from your amp (which has your ipod/computer etc connected to it + L and R speakers) into the sub to give your hifi extra bass? You’d need to go from the “pre out” sockets on the amp (assuming it has them) to whatever input the sub has.

            What’s the model number of the sub?

            Btw if it’s a sub from a set of computer speakers then it’s not 500W RMS – this is the kind of rating you’d expect of a PA speaker (there are various ways for manufacturers to fiddle the numbers to make their products seem louder/more powerful on paper, it’s pretty common in computer and car audio). 20W RMS would be a more sensible rating for a computer sub.

                  Although it might say 500W on the spec, it’s a common marketing ploy used by manufacturers to quote the peak power, as opposed to the more useful (and lower) RMS rating (and there are a few other fiddles they can do to further boost this number). Tbf it looks like a pretty big computer sub and I’m sure it’s plenty loud enough, but it wouldn’t compete with a 500W RMS into 4 ohms active PA speaker like this one (500W-ish anyway, I used two of these to do a small open-air stage at a festival and it was loud enough).
