I'd like to run this amp on my bench with a set of 8 ohm speaks, though those specs are not listed:
http://ampguts.realmofexcursion.com/Rockford_Fosgate_Punch_75HD/
I do have a deep cell battery, but its probably pretty run down. I've read about setting this up with a car charger. Do I just hookup the car charger to the battery then jump from there to the power connections on the unit?
Any thoughts on how good this may sound for a home audio setup?

This is what I've been working on for the last couple of years.
Fully active system all 4Ohm speakers
Speakers:
tweters from MTX Black Gold series
mids from Lanzar DC Series and MTX Black Gold
subs from Monocar Raptor series.
Amps:
Lanzar Optidrive 4150
Autotek 300XI
Crossfire VR2000D
Head unit:
Rockford RFX 8140
Processors from Lanzar:
G2M
E30
X3
at the moment the box is a prototype but the sound is still amazing.
The power supply weighs in at 70 pounds and can put out a constant 240 Amps of current.

It is not ever a good idea to run a Lead/acid battery indoors. If you have an old computer laying around you can take the power supply out of it and use it. Using 8 ohm speakers are the wisest choice unless you are wanting to spend big money on a power supply.
If you do go the computer power supply route, let us know and we can let you know what you have to do to get it connected. We will need to know if it is an AT or an ATX supply.

Firstly computer power supplies are not regulated so they won't actually provide any real current and maintain 12 volts.
Secondly why would you bother, you firstly need to bring mains voltage down to 12 then step it back up again just to drive the speakers which seems totally pointless and wasteful when a home amp will do the same job with far less waste and less heat.
Thirdly I know that I wouldn't want a car battery in the house with all the associated fumes and ongoing costs.
SLA's are sealed,and won't vent gasses into the house (under normal conditions)
I rewound an old Microwave Oven Transformer (MOT) to use as a 12V supply.

I should update the page someday,but I'm lazy.

SLA's are even more expensive just to do the job of a home amp....
i have a couple of old school non HD versions of the punch 75
these specific amps wont run off of some battery chargers, chargers cant provide the current fast enough for these amps,
you'll have to get a dry cell battery or something....maybe a UPS will work , those have 12 volt batts inside.
all you really need to run that amp is a 12vdc 18ah battery, around $30... and hook it up to the charger.
on the battery alone youll get about 30 minutes full volume playing full range on a 15" speaker...or... just turn on the charger when your playing.
cut out the sub bass and the battery will last longer, that way you wont have to turn on the charger and have the ripple come through the speakers.

It will sound nice if the speakers are really sensitive, and you won't need a large power supply (MAYBE 10 or so amps constant capable to be safe) to produce the 50 or 60 watts the amp will be making. You definately won't need a battery, but a small cap, .5F or so will keep the dc smooth. The punch amps don't like AC ripple, like someone else said.
The good thing is the damping will be nice and the frequency response will be good if the speakers are decent.

Nice looking setup! How do the subs sound in your towers? I bet you can dim the lights in your living room if you turn it up loud enough, eh??
The whole set up sounds great. But I do have to rebuild the boxes with the correct air volume for the Raptor Subs. I had a pair of Phonocar midbasses previousely in there so the volume was correct.
At the moment I have no Sub attached to the VR2000D. 6 Months ago I had 4 10" MTX Black Gold running on the VR2000D and I could shake the lights in the basement, I live on the 3rd floor!!!
The problem I am having on the Sub issue is that I need something that is magnetically sealed so the magnets will not effect the TV picture!! This is turning into a problem. I could not even have the box with the MTX Subs on the same side of the room without turning the TV screen purple!
