I'm using a pair of 8 ohm house speakers in a 2 channel configuration my car. I want to bridge my 4 channel amp to get more power. My concern is that in bridged mode the amp is "4 ohm stable". Will I fry the amp (or blow fuses) by driving 8 ohm speakers in this set-up? Also, the amp has a switch for 2 channel/4 channel that I have set to 2 channel. If I bridge the 4 channels to 2 channels, do I set the switch to 4 channel? Also, will I still have stereo sound or does bridging turn it into mono? Thanks in advance for any assistance.
you can't wire each 8ohm speaker into a 4ohm impedance... it can be done if the pair of 8 ohm speakers were wired together though to one channel...
Wiring Speakers If you are unsure about how to wire your speakers I would suggest looking up wiring diagrams online and doing your research on ohms law. If you bridge your speakers you should be fine because 2, 8ohm speakers wired together should drop to 4ohms. As for the Stereo or Mono question. If you bridge an amp you are basically telling the amp you have one channel for output and you will lose separation of the channels from left to right. If you are looking to just have full range you might just try wiring it up normally. It might sound ok at 8ohms. It will just be less resistance on the amp which will produce less power to the speakers. I would suggest checking the manual on your amp and see if it would be stable at 8ohms before doing anything tho. If you wanna get really advanced you can actually add resistance to the speakers and drop the ohm load by making a crossover for each of the speakers. But you will have to look that up on your own. It would definitely be like a little science project for ya unless you are experienced with wiring and if done incorrectly could be a potential fire hazard. lol Good luck.
