home setup for car audio stuff

[limitkid7]

this is an easy question..

what are the products i would need to be able to have a setup at my house?

of course i'm talkin about hu/amp/speakers/sub, but what kind of stuff do i need to make that work, such as like where does ground wire go to, etc...
kind of like how they have setups in stores, what are the materials that that are needed & where to purchase?

if you have the know-how to build a big *** power supply or you have 130bux to buy a big *** power supply then all you gotta do it build it, or buy it, and wire ground to ground, and pos to pos
the biggest power supply i saw in a catalog was only able to put out 40amps, which is only capable of puting out 480 watts total in a setup. but the avg HU only uses like <15 amps or something, so you could prolly order a smaller 15-20amp power supply from radio shcak unless you wanna hookup a big *** sub amp- in that case, you gotta build a hige one, and thats actually purdy expensive too.
hope i helped
