well I was thinking about using the 150w opus and adding a bunch of speakers, gps, mp3..etc I want to keep the head unit and add aditional speakers to the car and these things add up when it comes to wattage
well I want to hook up my car sound to the head unit so I guess im going to have to buy an amp to run that. I wonder how much power my head unit has because if it had enough power id hook the additional speakers to that, but I dont know if the extra connections would allow that. I know I need a PIE adapter then PIE to RCA then Y audio cable. No with that setup I couldnt hook speakers to my headunit, they need to make more inputs for the audio cables
I wanted to power additional speakers without the use of an amp because I dont want to spend money on an amp so I want to hook my car computer sound card to my headunit and additional speakers but thats not possible. I dont need additional speakers anyway I guess 6 standard speakers is enough. I want to power a lot on my carputer and I dont know if 150watts is enough especially since I dont know the wattage of VIA's (im sure they arent that much wattage) plus 4 usb devices, keyboard, mouse and much more.
Increasing your CarPCs Power Supply won't make any difference, this just powers the components within the CarPC itself, its the output power of the headunit which says whether it will power the speakers.
