I just got a stereo system installed in my M998 with a console, rear speakers, sub and amp. When I went to pick it up the shop told me that the converter that I supplied wasn't working because it was adjustable and the amp required a constant 12v converter. I have the Orion 2412-70a. Does anyone have any knowledge as far as what the correct converter would be? Any help you can give would be appreciated.

Wrong 24v to 12v Converter?

I do have the same and yes, it is adjustable. But when it is adjusted, it does not fluctuate voltage. I set up mine to like 12.8VDC or so. I can not speak about music equipmwnt but know many people with the same and no issues.

Adjustable just means you can set the voltage output you want, not that the output is going to adjust itself.
Sounds like you need to find people with a better understanding of electronics to do the work

guess they didn't have a volt meter?
Perhaps I am just a simpleton, but if we have two 12V batteries in series to make a 24V system - instead of using a converter, why not tap off the first battery's system ground and 12V, install a circuit breaker, or bus fuse, then a fuse box for the individual 12V circuits?
What do I know? This is what I did. No need for any converters.
I do have a 200 amp with the lead that charges the 12V battery. But I ran this configuration before I converted to the 200 AMP.

What's the amperage of your stereo system?
If the total amps are more than 70 nothing will work. More amps in a converter are better, your equipment will draw what it needs.

If you do not have a dual voltage alt. then if you draw off of the rear battery you will unbalance the charging system and the batteries will not last nearly as long as one will be under charged and one will be over charged, the larger the 12V load the faster the batteries die.
With the dual voltage system I would not pull more than 15A or so despite what claims the manufacture makes, those regulators are very expensive compared to an inverter and was designed to compensate for the transmission TCM which only pulls a few amps.

If that amp was designed to go in a vehicle then it should be good to around 15V, in modern automotive alternators it is common to see 14.2 -14.5V so them saying it requires a constant 12V is also wrong.

If more than 70 amps is required, the Victron Orion converter can be run in parallel up to 5 units, for 350 total amps 12V

That's called an "evil tap" and it destroys batteries for the reasons Mogman explained.
I tapped off the first battery in the series. I have 200 amp. It works fine.

Never tap the front battery…the rear battery is the correct battery to pull 12v from.

this topic just gets beat into submission it seems weekly….
the hmmwv like all modern tactical vehicles use both 12 and 24 component’s , pulling 12v to feed those components is how they were designed,
work, the 14v tap coming off the regulator was specifically designed to prevent An imbalance of the battery feeding 12v component, there is nothing evil about it and I’ve done it for over 30yrs with absolutely no issues On hundreds of trucks that have come through the shop.

Dual voltage alternators.
And as you said, it was specifically designed to prevent an imbalance.
Without a dual voltage alternator specifically designed to avoid it, it's an "evil tap."
As I understood it, the original reference was without a dual voltage alternator and the protection provided.

long before dual voltage, I ran off rear battery,like anything electrical, you have to engineer the load, so a cigarette lighter adapter, USB charger, backup cam…none of these items draw enough amps to create issues, the key is, don’t have constant power draws, you need either the ability to turn off all items when sitting or install a relay to switch the 12v on to the devices, i personally now install a relay to switch the 12v on, just like the TCM off of 290C/291C.
