New here, not sure if this is in the correct place to post and sorry if it isn't.

Looking to run all my leftover car audio off a psu to use in my shed. Have head unit, amp, sub, speakers and a pc psu.

Ito be honest, don't have the knowledge or skillset to complete this so I'm really looking to see if I can find someone in Auckland to wire this up for me, for a fee of course.

Appreciate any help

Does the PSU have multiple 12v rails or one big one? They do not like the 12v rails being combined when I tried it with a split rail one. If its split then you will need to check how much current each of them can do and put one amplifier on each rail.

Also, at only 12v you will not get max power out of most audio gear, it can be significantly down on the nameplate rating that is usually done at 14.7 or so.

what size amp?

especially with subs, i would be inclined to use a car battery and connect a auto battery charger to it. thats because psu's don't like pulsing type draw that music demands.

It works fine, I have done this with a "150+150+300w" amp in my old jukebox shell I got a while back with a dual 12" car sub box sitting beside it. Only really used the car amp as it was what I had around and it had the crossover in it that I needed.

Graphics cards are a very pulsed draw type as well, and no problems at all.

The OPs PSU is a single rail so no problems at all with it overloading one rail while there is capacity on another, just need to make sure to take enough 12v and ground cables out to the amp so that none of them try to carry more than 10-15A each as that is where those crap molex plugs start to cook at.

power supply is a little marginal, just don't go cranking it.

the psu is 500w continuous, the subwoofer is 500w on its own.
