hello, i am wondering if using a home stereo (sony mhc rg660 200w rms x2) would be ok to use as a sub amp to run a couple of 200w rms subs.




i would use the sub pre out from my av reciever and split into two rca's and plug into the input of my stereo.




any one see any issues with this?




i currently have a warfedale power cube 12 and just seems to be a bit lacking, was thinking of getting a couple of 8 inch subs into a box and run off stereo.




cheers for any help

I'm not an electrical engineer but my uneducated guess would be that it depends on the signal to noise ratio of both the input Jack of your stereo and its amp

And the amount of current needed to drive the sub vs how much current your amp produces.

I Once destroyed my dad's speakers by plugging my bass guitar into the input Jack of his hifi.

Yeah it would probably work, but I'm pretty sure you'll find the results even more lacking than the Warfedale.




The specs on that unit may say "200W RMS x 2" but the real power is probably more like 50W x 2, whereas the 150W quoted for the Warfedale is probably pretty close to the mark. What you're proposing can be done but you'll want something better than that 'all-in-one' home stereo to drive it. A friend of mine ran 2 x 10" subs in stereo in his system for a while and it worked OK, but then he used a 'seperates' stereo amp that was rated at something like 150W x 2 (and that was a real 150W!)
