If you hook up your speakers in parallel, as most people are want to do, then you will increase the load on your amp to the point that you may fry it. Almost all modern amplifiers recommend a 4-ohm load or lighter. Two 4 ohm speakers hooked up in parallel will appear to the amp as one 2-ohm speaker. This is a no-no. The very same speakers hooked up in series, however, will appear as an 8-ohm load and your amp will be very happy with this load. |

Trying to hook up your speakers without frying your amp.
You may have realized by now that there are various types of speaker output configurations used in the modern car stereo. How best to deal with your wiring in order to not fry your car stereo or amplifier can be confusing. Another area of confusion is the difference between a parallel and a series hookup. The figure below shows examples of these types of wiring. The common ground type uses the ground to return the speaker negative lead to the amp. The common hot configuration returns the speaker commons to the amplifier on a HOT wire, and you cannot ground this common return wire without damaging your stereo. The true four channel output has all the wires independent from each other and they are ALL hot.! Notice also that the fader control comes before the final output amplifier stage, unlike the other two styles. Take a look at the following drawings, and they should help you to identify the type of wiring hookup that your system has.
