Is it common for 4 channel AMPs to be passive when off, IE, switched off when running Stereo off of battery and can still hear Stereo just not amplified? I purchased a decent low end amp and have not hooked it up yet and was curious if this is the case or if I can wire it in such a way that it does function like this.

I realize I would have to put a physical switch on the remote wire but that is no big deal to me.


P.S. I looked over the cheesy manual and it doesn't specify that it is or is not. It is a Dual XPE4700 800 Watt 4-Channel Amplifier.

Any help is appreciated,
Respectfully,
Richard

The amp would have to be on for the sound to come out of the speakers. If your turn the amp off while the truck is running and the radio is on you will lose your sound.

That's what I was afraid of, is there anyway to wire it for both cases? Has anyone done this? The only way I can think of to do this is to wire it to a switched distribution block and then just switch it over but I wonder if any company makes one for this purpose, hmm.

NO. and why would you want to?

So I dont suck my battery dry fast when I have the engine off and listening to the radio, E.g. at the beach or the rental cabin but outside on vaca.

I can do it via a switched terminal but just didnt know if the amps today are passive like that nor if there is a switch like that on the market already.

It takes a while to kill the battery with the radio. In my old ranger I had two amps (4 chan and a mono for the sub) and I would leave it on for hours with no problem starting later. Have a good battey helps too.

I have a single amp powering twin 15" in my 67 impala.

I got a battery that was 100 CCC more than needed and a 1 farat cap.

While the car took a second to power the system, when i went somewhere i was fine with it.

My car would last cranked all the way up for 7 hours while SHUT OFF. i tested it all out in a pallet party. Rap or rock... It lasts.

I had my sub amp wired with the 12v ignition switch so that the amp would only turn on when the truck was running. It would not turn on when in accessory (turn the key to first position). I would be able to get sound out of the radio thru the factory speaker locations but the subs would not be on. Might be something you might want to look at. I tapped in under the steering column. Don't remember the color of the wire.

Thanks, I'll look at that option.
