Modify Home system amplifier unit to fit in car

[honeybakshi]

Hi,
I am just thinking to do an experiment. I have a AIWA 800W music system which i am not using. I am planning to buy a car amplifier for my car. I just thought that my AIWA system must be having some sort of aplification usnit installed inside to give 800W. So i just thought to do an experiment to take out the amplifier unit from AIWA, attach a DC power source to Run it and then use it in my car.
I believe it should work. Please suggest. Is it possible?
Also, I want to try use the speakers of the AIWA system in the car. but there is no information mentioned on the speakers. It seems its a 3" or 4" speaker. I dont know the exact size. I just thought of using them in the car front doors. I believe these are component speakers. Am i right? can they be used?
I want to do this experiment just for understading and not for money saving. May be i want to design my car system myself.

I'll make this simple.
It's not really 800 watts, that's a gross overrating to get you to buy the product.
The speakers in an Aiwa system are cheap and not made for any other use.
In other words, it's not worth it.
Do it right or not at all.
Aiwa isn't even a company anymore, and for good reason.

I think you need to understand a lot more about mobile and home audio before you proceed with this project. First your Aiwa 800w music system isn't 800w, marketing lies about power. Second, you probably can't just run the integrated amp off 12v DC power, most amplifiers used in home audio run somewhere between 24-36v power supplies to reach the specified output power, at 12v your output power would be significantly reduced if the amp works at all at that voltage. Third, integrated bookshelf systems are not really modular, you'll have a hard time gutting out just the amp section if you try to remove the CD player or tuner you'll probably make the amp stop working. If you want to DIY a mobile sound system you'd be a lot better off building your own amps rather than trying to re-purpose something that was never intended for a mobile audio environment, there are a lot of simple class D amp kits out there that will work for a mobile audio amp, junk yards, pawn shops, craigslist, etc. have cheap mobile audio speakers that will be easier to install in your vehicle than some odd ball size home audio drivers.

For a good sounding and clean looking installation it's best to use purpose built car audio gear.

Bad idea. Too much work for what it's worth. Also, home stereos usually output at 8 ohms or higher but most car speakers are 4 ohms. High end home receivers and amps can handle loads that low but cheapo units will go into protection or plain burn out when turned up.
