Amp turn on wire

What voltage is that sucker looking for? 12v? 5v? I have a sub box and amp that's been laying around for awhile and it's time to get them reinstalled. But I seem to remember it not working very well the last time I had it hooked up (different car- coming up on about 4 years ago now since it's been installed). Before I tear up the interior of my car to install it, I'd like to first know if it works.

It is 12v I just looked it up.

Sweet thanks. That's what I figured it would be but wanted to check before I put a 12v cable into something looking for only 5v.

It's also VERY important that the wire is at or above 12v. The turn on trigger in the amps can have major malfunctions when that voltage gets low. If you are turning on more than one amp you need to use a relay. I will post the wiring diagram if you need it.

Yeah, that would be great. Right now, it will only be one amp. But I might amp the front door speakers in the future.

you only need a relay if the input turn on signal is weak. I run two amps and have never had to relay boost the turn on. it all depends on the input that you are using. if it is from a aftermarket head that is of decent quality you will be find. your performance issue was most likely (and in most cases is either a Ground problem or power supplied from the vehicles elctrical system problem) Make sure you run the proper gauge wire for Power and Ground. and that your connection are solid. if a wire is too short do not butt connect or solder on more wire, Run a new length of wire to the amp. your ground should never be more than 18 inches long and the shorter the better. also add a seconary ground from your battery to the chassis in another location close to the battery but not in the same location as the factory one.

Try to keep your wires away from major harnesses or from passing to close to components like the fuse box or BCM
these generate noise problems. The old stories of running power and RCA's down oppisite sides of the vehicle are False but run them clean. Zip Ties are you friend. this should get you through most of the hard parts with little trouble.

If you need anymore help feel free to ask.

You'll have to forgive my being an old timer in autosound. Years ago, the only head unit of any major brand that had the capacity to turn on more than one amp without problems was Alpine. I'm sure most manufacturers have madt the remote turn on more durable than in the past. I was posting something that most people never consider.

Well, I wired it up on Friday. It works. But now I've discovered that the sub box is cracked. When the woofers hit, the box flexes and rattles and sounds like crap.
