If you can fit the wire in there then go for it. Make sure it is securely in there and dose not have any bare metal wire touching the amp. Also you might want to put a fuse some where on that line. If not you can either get a small distro block or go directly to the battery just be sure and fuse the cable.

Hey bberman. As far as putting a relay closer to the HU, why cant you tap from the factory 12V? Isnt the constant radio wire factory fused? Or is that not the issue?

Soon, I will have a few items in the dash which require remote turn-on in addition to the amps. Need to know. Thanks.

F4Pilot that constant to the relay is supplying what ever you connect to the relay with power. You wouldn’t want to add a load onto the wire supplying power to your head unit would you?

I'll say no, because thats the correct answer? adding fans to cool amp - Page 2 - Last Post -- posted image.

Are we talking E = I X R ? Which part of Ohm's Law is applicable and what does that translate to in a negative outcome? Burned out head unit?

Thanks much for taking the time.

Well then why don’t you get your power for your amps from the head units constant?

I’m not saying it wont work I’m suggestion the best way to do it is to run a separate line to the relay. Let’s say you have a 45 amp relay and you are running 40 amps off the relay do you want to end up pulling an additional 40 amps off that constant wire? Do you want to end up like this?
