Haes amp with subwoofer?

Recommended Posts

I have bought a rear speaker subwoofer off Ebay. I didn't realise that the speakers were such a low impedance (found out on here after I'd measured it and thought it might be faulty!).


I plan to buy a Haes 6x40W amp (also off Ebay - plenty on there) but I can't find any spec's. Will this amplifier drive the low impedance directly? If it won't work then I'll add a series resistance (currently running both channels off my home hi-fi with a 6 ohm series resistance to make sure that I don't blow the amp).


I'm planning to get a couple of crossovers (if I can find some that work with 2 and 1 ohm speakers) to turn the speaker into a stereo speaker (at least for the tweeters) which is going to give me something like 1 ohm minimum impedance (based on the 1 ohm bass speaker).


Also, any idea if I can get a plug that will connect to the factory original four pin connector on the speaker? If not I'll replace the complete wiring.


Finally, what size pin inserts do I need for the connector that plugs into the amplifier?
