It almost cost me my entire elec system.Thank God for hind site and I put a 10 amp fuse instead of the 30 amp "just in case" whew! Anyways I found 2 site that are very infomative .they are as follows.....https://www.bcac1.com and https://www.electronixwarehouse.com/education/main.htm .So I managed to hook up my deck,6xs audio controler,10 cd stacker,3 alpine amps,2 tweeters,2 mids,2woofers,2 subs,capacitor,extra batt,biult the box,for grand total of 4500 ass kick'n watts ,4" drop is next,then a divource!!

Well that was interesting, Dan.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I think he was having a conversation with himself, Dan, is there a guy on your shoulder talking to you? What he was talking about is simultaneous stereo / mono operation or 3way operation. Many 2 channel amplifiers are capable of running like this. It is most common to use a sub and a pair of speakers in this configuration. The sub goes to the bridged channels and the speakers to the stereo channels. A built in active crossover in the head unit or the amplifier cannot be used. Instead, you would use a 200-400 uf cap on the main speakers + leads and a 6mh coil on the subs + lead. A note here is that you cannot go below 4 ohms impedence on the sub unless the amp is capable of running to 1 ohm stereo, thus also would then be capable of 2 ohm mono. ------------- Top Secret, I can tell you but then my wife will kill me.
