Hi,

i was walking home when i found a 12" sub that worked for 15 bucks and couldnt pass it up but i was wondering if there was a way to pu my old stereo speakers and sub together for like a home theater system for computer/computer without having to spend $200 on an amp i considered using a/v cables into a RF switch box but with the amount of different splitters and reconnecters to get everything hooked up and have it work as one system would cost me like $40 and there isnt a 100% chance it would even work so i was hoping maybe i could get some help any suggestions would be helpful

Not enough info.

Does your "old home theatre system" have a discrete sub output from the amplifier, and if so what inpedance is is designed for (e.g. 8 ohms?)

What is the impedance of the 12" sub speaker you bought? (possibly 4 Ohms?). If so it could be injurious to your existing sub amp, assuming your system has one.

You lost me completely on using an RF switch box for AV (Audio) though, Radio Frequency and Audio Frequency are VERY different in levels of current.
