Thread: Is it something wrong with that?

I would get a DC-DC power supply if I were you, I started out
with a DC-AC inverter and the sound quality sucked because of all the noise being created by the inverter, you could probably get rid of most of the noise if any if you ground everything properly but seeing that you have 3 separate amps for good clean sound I would invest in a good DC-DC PSU like a Keypower or an OPUS

get an OPUS, you WONT regret it And btw, your setup looks ok

I would not ground the fuse block, and I'd change the main fuse to a 4x20=80amp

Keypower or OPUS?
Are they 200W? (as my shuttle needs 200W)
Where can I get them? (a link please)

looks good to me except i would make sure your 3 ground blocks all connect to the same point on the vehicle.

Just because you have a 200w power supply doesn't mean you NEED 200w.

Add up your consumption by what each part needs, then figure out what size you NEED.

200W never hurts tho And really, AC/DC really isnt that bad if you properly ground everything. I just get a bit of buzzing when the computer is off (but then, its never off, or if it is, the stereo is on the radio). And the buzzing stems from the 1U PSU i have not liking the psuedo sine wave (stepwave) that my inverter generates.

Thx to all you guys. I always get a proff help here..
But it seems that my car is very spesial..
I don't have any buzzying or things like that even when my pc and inverter are not grounded...
But my alternator was a big problem with my LCD...
I could almost read the rpm form the engine on the LCD...
But It seams that I have fixed the problem... So I be back with some recomendation if this system works...

(I use a filter that some radio/tv service guy has ordered for me) it looks like this is very good..


A DC-DC PSU is my dream, but I must have 200W as I will put a sattelite tv, tv and radio, GPS and one Seagate 80GB HDD...
So I think that PC will use some power then...

BTW, AMD CPUs are not a low power CPU so they like power...
