Default I want a home theater made with car audio!

I'm really curious and interested in eventually building an entire home audio system using car audio stuff. I just really love the way car audio products look, to be honest. I love the way fancy electronics look, and I like to show them off (to myself at least, lol), right down to the wires and fuse blocks and everything. Has anyone come across a definitive resource for making a home audio setup from car audio? Thanks in advance,

Due to the power supply requirements for a high power system, this is generally impractical. Expect to spend ~$400 on power supplies if you want anything near 1000watts (seems like the minimum for car audio guys).

Unless you have a multimedia head unit or an amp (like the Autotek MM 5.1) that has the proper decoders for home theater/surround, add the cost of a decoder.

I don't need that much power. I only need about 350 watts RMS for the sub and another 150 watts/channel RMS for the speakers. Both 4 Ohms.

Just two front speakers, btw, not 5.1. Left, right, and sub.

Still just much easier (and potentially safer) to use 120VAC products instead of trying to adapt 12V for use in the home

What do you like about the car products? Maybe we can recommend home amplifiers that fit the bill

Oh hell, I will recommend two.

Onkyo TX-SR series HT Receivers starting with the 600's...Or, the Panasonic XR series HT Receivers, like with an older XR45 (I have two and they will never leave my possession). Both very good, and relatively inexpensive...

Can't go wrong with either...

Nah I want car audio stuff. The unique, personal aspect of it will be off the chart, plus I get to design and build everything myself, plus it's unique, plus it's relatively affordable. I just want to know how to do it right

Get a big SLA battery,and a beefy SMPS with a 13.8V output,add a stiffening cap if you feel like it,and you've got power covered.Do Not forget the fuses on every wire to/from the battery.

Lots of home speakers wired in parallel would like battery's low impedance . I'd love to have a dedicated amp armada to drive them !

Find a 12vdc 60amp switching power supply ( http://cgi.ebay.com/POWER-SUPPLY-AUD...3286.m20.l1116 ) and a decent sized agm battery ( http://cgi.ebay.com/KINETIK-HC1400-K...d=p3286.c0.m14 ) to smooth the voltage. That will be enough for the power you listed unless you continuously run it at maximum rms. You will need to turn off the switching power supply when not using the system... to conserve electricity. The battery will keep the memory up in your head unit.
Don't worry... you can always turn the gain down!
