While you wont find them in many local stores, the good news is that theyre affordable. Most amplifiers have a setting called bridge mode or bridging (to increase the output power by combining more than one channel). Alternatively, I have become aware of wiring 8 speakers to 4 channels. You can also check the owners manual for more information on bridging capabilities. Fourth, ensure that the volume on the -4-Channel Amp is turned up. For example, I have owned many car amplifiers and normally used 4 or 5-channel amplifiers. How does an amp make more power when bridged? Example #1.

Be aware of the fact that if your amplifier is a stereo amplifier (amplifying both left and right), bridging it would cause it to become a mono amplifier (amplifying from one; either the left or right). The good thing is that all you really need to know is roughly what the resistance of a speaker is. Partly due to tradition in the electronics world and partly due to various other electrical reasons car stereos are commonly rated at 4 ohms and home stereo speakers around 8 ohms. Using these will allow you to keep the total speaker load (speaker Ohms the amp sees) to a safe level so the amp wont get damaged. Reply. In most cases, you only need 2 RCA Y adapter cables.
