Pc ---> Amp

**SuperMatty** · 08-07-2002, 04:45 PM

I've simply run out of dash real estate now that I'm going to be putting my 10.4" into it instead of on top of it, and I am considering getting rid of my head unit. I noticed in the past posts many complained that when running the PC audio directly into the amplifier, 'it sucks to use winamp for volume." Why is this? I figured on using that for my EQ.

Additionally, I know that all of my speaker wires currently plug into my head unit in my dash, so if I add a 4 channel amp to do this, would it not be more appropriate to place the 4 channel amp in the dash area somewhere so I don't need to rerun all of my speaker wires to the trunk?

Lastly, is it common for multi-channel amps to come with 3 or 4 inputs that can be run simultaneously? I planned on wiring the front speaker outs from my audigy into the front speakers in my car and the same deal for the rear speaker out and rear speakers. I also planned on incorporating some voice-feedback stuff in my car using an ISD1000A sound record/playback chip and would like to have another input to my amp reserved for that.

If not you can always use the linein on your computer. I plan on using the cd linein since I'm using digital read for the cdrom

good luck mounting an amp behind your dash, its usually not possible and if you do you have heat issues. mount the amp under a front seat if you really want it close to the dash, but, running wires isnt all that hard.

also, amps can handle multiple inputs, but will likely need to get some piggy back cables.

I have two amps.

One is a 4 channel, and has 4 mono inputs, one for each channel. If I had surround sound, I would run the fronts and the backs seperately. I only have stereo sound, though, so I split the signal for the two rights and two lefts.

I also have a two channel amp for the subs, which runs off of the same stereo signal.

I use winamp for volume control, no problems.

Wasn't it a pain running your speaker wires though? Like I know in my car, my speaker wires are bundled together with like 13258395732 other wires running down the sides of my car.

the trick is to run new speaker wires from the amp to as far as you can go then splice into the existing wire. (easiest is to splice into new wiring harness behind your headunit)

Sound Quality people probably would want to run new wire all the way to their speakers.

But I think most would say that 16 guage or what ever the automakers use is good enough.

Your best option is probably to ignore the speaker cables that are already in your car, and run a second set from the amp directly to the speakers.

Matty, someone a while back suggested using an MVC made by Audio Control, it is essentially a "master volume control" .. basically its a knob that controls the over volume of your setup, so you can run everything into that and then just control the volume via winamp and/or the MVC. Thats what I plan on doing. Its got digital inputs as well.

Good luck.

You gotta link to that MVC thingy?

I'd be interested in a master volume control as well, is it something like this? http://www.pac-audio.com/products/lc.htm

will these things work?

Also, I've heard some discussion about the voltage of the speaker out jack from the computer not being the proper voltage for most amp inputs. Does anyone know any more about this?
