Speaker wiring question


Hi,
I have a pair of outdoor speakers for my deck that sound OK, but they probably only go down to 80 or 100hz. I would like to try to supplement the low end with a single bass driver from an old speaker as a makeshift sub wannabe. I have connected it with speaker wire from the B speaker outs (an old Yamaha receiver) left channel, and though not perfect, it does improve the bass output. My question is, can I connect it with both left and right speaker wires akin to using a Y connecter for a real sub, or am I likely to be sorry I tried? I am assuming that it will not affect the A pair of speakers. Thanks.

Don't do it! A "Y" connection will short the two amplifiers outputs together. While preamps are unbothered by this which is a way to get a mono signal (they are short proof) power amps are likely to burn out.
Not sure what connections you are talking about?
Eldartford,
Thanks for the caution. I'll settle for the way I have it.

A true subwoofer for your application will have a dual voice coil (right and left). Go to partsexpress.com or mcmelectronics.com and buy one for $10 and you will do much better.
The other option is to get a simple sub crossover which will filter the bass out of the 2 mains and send it to a single subwoofer. I've got an extra crossover if you want one? It will run you $10.
I'm out of $10 options...
