audio system idea

I was looking at my home stereo today, it has a sub 10'' in a box and it is connected to the front speakers, it says it needs 100W RMS continous which I'm sure is the same as in the car. So I was thinking would this work?

This is stock:

I would still have the front speakers and it would only be 1 sub.

Yes.

Most passive home audio subs have High Pass outputs for the other speakers. Meaning that there's a crossover inside the cabinet, and that your speakers that are connected to the sub will have the bass reduced from their signal. (To Protect them)

Edit: Let me clarify, only IF your sub has L & R inputs, and L & R outputs can you wire it up that way.

Home stuff is usually 8ohms. Car stuff usually 4 ohm. Headunits don't have enough power to power a subwoofer. Sorry, but crappy idea.

Go buy some real car audio even if its from Walmart its better than your home/car theater idea.

Ya I know its a bad idea but I just wanted to know for sure if that would be bad to do. I'm gonna spend the money and get a proper amp for the sub(s)

Also aside from the technical drawings a stock Delco deck isn't gonna put anywhere near 100wRMS. Maybe 20w RMS total power if that. Need amp for a sub or you're just gonna waste time and/or break stuff.

NOOOOOO

 

DO NOT DO THIS.

 

no head unit stock or aftermarket is designed to power a sub. a sub needs an external amp to power it.

 

you do have some options though.

 

many 2 channels amps can be run in 3way mode. provided the speakers and the sub are all 4 ohm each.

or a 4 channel amp use two of the channels to run the speakers and then bridge the other 2 to 4 ohm bridged and run the sub provided it is 4 ohm.

 

or use 2 seperate amps.

 

to get the signal for the amps you can either find an amp that will accept a high level input signal. like the signal that comes from speaker wires.

OR

buy some LOC's (line out convertors) these will convert the speaker level signal to a rca signal that most amps can handle.
