I've have a few other Server PSU and plan to setup a system in my garage with the spare car audio that I have left over.

my high school setup.

Hey are those pioneer 10's in the top center? Those are what Im currently running, have the model number for them?

I don't have the model number. I do remember that they are the free-air models. I still have 6 of them. I would have to uninstall them to see the model number. They could be TS-W253C .

maybe thats why mine sound like crap in my ported box...

I have an old gm-x962 pioineer amp that works great!
Drivers apparently need replacing

I used those speakers in isobaric, aperiodic, sealed and bandbass boxes. Never had issues with them. I even use to DJ with them.

I have a family now, so my sound system is way smaller...

Maybe not then.. Found out my box is a Bandpass enclosure... if that means anything..

Sounds good in my 01' Kia sportage...

naah, it could be your amp. These woofers need some power to sound good. I would stick some pillow stuffing in your box. It could be that your box is leaking air if the woofers are in their own chambers. I also use to add dynamat inside the box itself.

Here's a link of the box that holds 4 of those woofers. http://www.cardomain.com/ride/426334/2

Cleaned up my wiring, put an anderson 50amp connector on it(same one I use in my car) for quick changes

Looking good BB.

I remember having a box like yours in my room. I had it setup in a corner with the ports firing up. Chicks like sitting on the plexiglass while the music booms.

I use to run a bunch of caps with a cheapo car battery charger. Worked out great.

Thanks for this thread Snellemin. I got hold of one of these HP PSU's for $50 AUS off Ebay and it was local pickup. Works well and is a lot smaller than I thought it would be. Heaps better than the multiple 100's I would have had to spend to get the same current from a commercial PSU. Mine gets 12.48v no load.

I was in the same boat man. I was seeking a simple high quality 40+A 12V power supply without breaking the bank. I also didn't want to spend too much time hacking a regular computer power supply. Nice thing is, that I work at HP and have access to the Server group and PSU group. I got to open a few PSU's up and asked the designers and engineers what the limitations where and what not. I went on Ebay and started inputting different HP part numbers and found the older stuff to be dirt cheap and easy to mod. Easy as in, not having to open up the Power Supply at all. I also found that some people on rcgroups have used the same power supply I have listed. I figured that 47A PSU is more than enough for the majority of the people and $20 dollars is more than affordable for nearly anybody in this hobby.
