Hello,
Hope everyone is well at those times
I’m stripping MCC404m from my car, I won’t be doing car audio anymore.
I thought of repurposing this amp as home amp.
1) Do you think it will be an upgrade over my current amp Adcom GFA-535?
On paper, MCC404 is more powerful 200w@8ohm bridged vs. 60w@8ohm.
But, MCC has lower S\N ratio 105db vs 110db.
MCC THD 0.007 bridged @ 4ohm. Any guess what it could be at 8ohm load? (Does it matter/audible in real life?)
Attached spec sheet for both amps. (MCC manual, Adcom from web)
2) I will need a power supply for MCC. From what I gathered I can use a PC PSU.
MCC is rated at 12v 70A (100W ??? This one I don’t understand - 12v*70A=840w...anyway, I believe I should get at least 1200w PSU - Corsair XH1200 or something along those lines).
Please correct me if I’m wrong, any input would be appreciated
3) my concerns:
- will PC PSU introduce noise into the system? In theory i can add a capacitor in the chain, the same one i used in a car.
- is PC PSU a safe option? Do they have build in protection? (Basically, will this setup be a hazard, even in case I’ll do everything else right - securely connected wires, insulated, all that)
4) other reasons not to do that?
I thought of doing it because I thought it might be an upgrade over Adcom,
MCC has some EQ capabilities which may come in handy (well, depends on how quality it is, EQ on my pre-amp that i used (also Adcom) definitely introduced some artifacts in higher frequencies, so idk),
Lastly, generally I think its just cool idea, and a fun project.
Thank you

Find the cheapest ATX PSU of about 500W and try how will perform the amplifier at low to medium power levels.
If you like the set-up, then find cheap 800W or more server PSU, which has only 12V output.
I was using 4 channel car amplifier at home for 2-3 years in bi-amp configuration with it's integrated filters and the result was OK. But both the amp and the PSU were cheap solutions...
You will not make difference in the different THD of both amplifiers, but they will sound different for shure - they are different topologies inside...
All PC and Server PSUs have built in all kind of protections.
DON'T CONNECT 1F OR MORE CAR AMP CAPACITOR!
The PC and Server PSUs will trigger their short circuit protections at start-up, because of big capacitors.

ICE amplifiers are designed for in car use and are generally of poor quality when compared to their in-house counterparts.
That is not to say that ICE amps are rubbish but they have to make a lot of compromises in terms of heat dissipation and power supply requirements.
By all means power one up with a suitable power supply.
You'll get better performance out of a similar in-house amplifier.

The MCC404 isn't an ICE amp. I doubt too many power supply compromises were made, it draws 70A at full power.
A pc power supply will fall short of what you will need for that amp
A pc power supply just can’t keep up with the amperage you would need to power the car amp. This is why pro and home amps are so heavy. They need a large power supply system.

Server power supplies or big linear power supplies are better for this sort of thing, PC power supplies tend not to like large transients and can shut down prematurely.
Car show people use large 13.8v smps, they are all over amazon and eBay.
