Default Car Audio At Home

How do I connect car audio equipment for use at home? Car audio dealers demonstrate head units, amps, etc. in their stores so there must be a way to use car audio equipment with a 110 Volt wall outlet. Thanks for any info.

yep, sure thing... transformer able to deliver 100amps... weighing in at 50Kgs... bridge rectifier suitable for 100+ amps, and the heatinsk + fridge to go with it... and a few hundred farads of capacitors... ok.. maybe I went a LITTLE to far in the end...

I still use and test car audio equipment with 2 marine Gel cell deep cycle batteries (Interstate 800 cca) and I have a charger (40 amp) to turn on and off at a predetermined voltage (12.2 on and 14.4 off)....there are 2 1 farad capacitors connected on the output....basically an automotive setup

I powered my spare in-dash cd player with a computer PSU (power supply unit). It output 12VDC@4.2A.
But I ran the in-dash to my reciever; this way the in-dash ONLY drains about .52A.
Caution!! The AC line (from the PSU) may causes EMI humms.
I tried the PSU approach and got mixed results on humming. I am thinking about using a 12VDC@.8A wall adaptor or use a snap-on ferrite core to correct the problem.

I plan to run an old school Rockford Fosgate Power 650 Mosfet bridged (2 channels) on two subs and an old school Rockford Fosgate Power 300 Mosfet 4 channels on two sets of separates.

Just before xmas my dealer sold his Rockford display to some lucky kid with rich parents for his bedroom. I asked the same question as how to power all those watts and amps at home. His answer was to use a couple of car batteries and a reqular battery charger.

Regulated 12V DC power supplies can be had at any output rating you need.

For 10 amperes or less (head unit, no external amp) you can use the 12V section of an old PC power supply. Beyond that, Radio Shack sells one that does 25 amps (I think) and Pyramid makes them up to 40 amps :
