Parallel wiring has the opposite effect of series wiring. Load impedance drops; therefore, the more speakers you wire in, the lower the impedance. Lower impedance raises acoustical output. Speaker output increases because the amplifier's power output rises as the load impedance decreases. Load impedance should be held to a minimum of 2 ohms.
You may be temped to use typical electrical wire instead of speaker wire to save money. The copper in electrical wire is of less quality than speaker wire, and will be prone to rust. Also, the insulation isn't of the same quality as speaker wire. These points are especially important when dealing with car audio. Still, it can be done.

The following paragraphs contain general information about how to bi-wire speakers. If you are in any doubt about how to bi-wire your speakers or about the suitability of your system for bi-wiring you should consult an audio specialist prior to changing your configuration.
Below are the available wiring diagrams for the speaker configuration you selected. The resulting impedance (ohm load) is considered the "Nominal Impedance" seen by the amplifier. Note: One or all of the wiring options shown in this application may not be compatible with your amplifier because of low impedance loads. Please check your amplifier
Wiring the Right Way: Creating the Perfect 5.1 and 7.1 Setup. Sure, it's great to throw down a bunch of cash for a nice complete home theater speaker system and the amp that makes it all work together, but this is only the beginning. Although many people take wiring for granted or consider it only as a necessary afterthought, the way people hook things up makes every difference in how their
