Is "diy" "do it yourself?" Anyway, speakers are generally wired in parallel.
Yes, DIY is Do It Yourself. Whether speakers can be wired in parallel depends on the speakers and the amp; see my response to lemonie below.
I am running off a stock ford premium amp. its better for me to series the back speakers to one sub. Mike http://www.ZoeZo.com
You need to provide more information: we don't know what you're trying to do. L
Best answer so far. Are you trying to figure out how to hook both a tweeter and a woofer to a single signal source? If so, you want a crossover. Or are you trying to figure out how to hook two similar speakers to a single signal source? If so, the answer depends on their impedence and what that amplifier is rated for. If you hook them in series, you'll get lower volume but won't harm the amplifier. (Impedences in series behave like resistances in series, R1+R2, so two 8-ohm speakers in series add to 16 ohms.) If you hook them in parallel, you may drop the impedence below what the amplifier can drive; you must check the numbers first. Impedences in parallel behave like resistances in parallel, (R1*R2)/(R1+R2), so two 8-ohm speakers in parallel yields a 4-ohm load. If impedance goes too low, the amplifier will distort at best, overheat and possibly damage itself at worst (unless it's short-circuit protected; in that case it may just go silent in self-defense.)
