Relays & Capacitors, Using a relays to switch on power caps Options

[danny_t82]

I am contemplating another rebuild for my sub box and amps etc. as I now no longer need a cd changer as I have a mp3 player

One of the features I want to build in is a relay so that the capacitors are only activated when the stereo is on. Currently the LED displays are on constantly (when connected) which I can't imagine is great for the battery. An engineer said he could install a large relay to that the power caps are only on when triggered by the remote cable from the head unit. Has anyone done this or can anyone recommend what type of relay I should use as I would sooner fit it myself than pay through the tooth for what sounds like a simple job!!?

Also, because I want to go for a single unit approach (to retain some trunk space - see my pics!), I want to be able to remove the whole thing without disconnecting every single wire. Does anyone know where I could get some kind of connector that will allow for multiple cables to be connected/disconnected simultaneously (not including the phono cables obviously)?



Any help would be much appreciated!!

The displays have a very low current draw. I bet the circuit for the display probably has a feature that will turn the display off if the voltage is below a certain point. Also, good luck finding a 60+amp relay that can be triggered by the relatively low voltage of the remote signal. You may end up with a relay triggering a relay. In my opinion I wouldn't bother. Less connections are better when you're talking about high current power cables.

My personal opinion is ditch the caps and buy a deep cycle battery(yellow top Optima) and a High current alternator (check the group buy). You'll be much happier in the long run.
