Im going to be doing pretty much the same install you did. Was wondering about your speakers setup. If im correct you arent using the HU anywehre. When hooking up amp, to sound card, did you have to rewire any speakers or anything?

Do you have the monsoon system?

You can PM me now.

I started my system out like this. It's perfectly fine, and you get what is effectively a ground loop isolator for free (between the heads of the tape and the player).

Thanks, is sound quality effected?Hissing?Static? also what should be be the ratio of volume of the pc to the head unit? is there some way to calculate that, since I think it might be dependent on watts.

I have a problem with the sound in my carPC. I have an Alpine 7894RB and I bought and adapter for connect "AUX IN", next I bought a jack 3,5 - 2 RCA conector. The physical connects are OK.

The problem is:

When I'm listening music in my car by FM or CD source that's ok, but when I select de AUX-IN source I only can hear the music, video .... by one side of the car.

The balance control in CarPC it's Ok, in the Alpine the same.

Could you help me ??

Thanks a lot

Rubén

roller, make sure that the 3.5 jack is all the way in. I've experienced same symptom as yours and turned out that it's not all the way in. Also, sometime the outer jacket of the connector kinda in the way which hinders the jack to go in all the way.

how would you set it up to have the soundcard play the speakers off your head unit, and the soundcard go to your amp and sub

You use a multiple channel sound card.

ok heres what i want to do, i want to hook up the center/subwoofer from the sound card to the amp to sub

and i want to hook the soundcard up to the headunit as well so the headunit is hooked up to the speakrs, but in the diagram above it shows one Y adapter going to the head unit, which port is the adapter plugged into???

the adapter going to the SUB would go in the "CENTER" port on the sound card probably?

but where would the adapter going to the headunit go to, which port??? cause there is front and rear? you would hook up both right but how? thanks

You don't have to. I would suggest not to since your headunit input is only stereo. I think you should use the front channels for the headunit. Use the rear channel output for the subwoofer. The amplifer for the subwoofer will most likey (or should) have a low-pass filter crossover and can accecpt stereo input. There are other solutions but this would work just as well in your situation.

i just forgot im not even using my headunit, im using my carputer for music, so can i use the front channels on the sound card and hook that up to the front speakers, and the rear channel to the back speakers, and the center to the amp to sub?

Yes. Although you can't go straight from sound card to speakers. You need something like a amp inbetween to drive the speakers. You probably know this from the images. Just thought I'd make it clear for others who may not.

Just exactly how bad is a FM Modulator?

My head Unit (JVC KD-G405) doesn't have any inputs

I have the choice of hooking my PC up to the head unit with a modulator or buying an amp and making some kinda switch system to switch between the two (head unit and pc) to play through the amp. Currently the head unit is hooked up directly to my speakers as the power is good enough for me.
I don't want to lose CD quality sound.
What is the best bet?

I had modified my FM modulator in order to get "descent" audio - otherwise it looks like you are listening to Montreal radio while being in Ottawa 100 miles away.... and even with the homebrewed extended antenna, the sound get quircky sometimes - it depends of the other available radio stations. You might have to change your "station" from time to time.
All in all, it rarely gives a CD quality audio, there is almost always some parasite. But maybe its my cheap ratshack modulator...?

What did you do to make yours better Marsupial?

What sort of Wattage should the 4 chanel amp be? dont want it super loud, i also have a 1200W amp to power a sub but is only 1 or 2 chanel.
