hooking up stereo in a house?

[sciguy007]

im not sure how my friend is planning on doing this. he wants to take his box and amp and hook it up to his stereo in his room? is this possible? how does it get powered?

He'll need to get himself a 12VDC power supply to run the stuff. Radio Shack has 'em pretty cheap.

I hooked up one of my Sony subs to our receiver in the hosue yesterday to see if it works (since I made a box for it) and I just ran the speaker wire to one of the speaker inputs and it worked. Hit pretty nice for being hooked up to a receiver, but it can go alot louder.

Just make sure that is crossed over so nothing over like 100mhz's go through and ruin the speaker with highs. I belive you can but an inline crossover, or your amp has one built in you will be set.

well i guess to be more specific, his amp has a lo pass crossover, and he is going to use the preout on his receiver to go to the amp, and he only needs to worry about giving it power...so i guess 12v power supply is all he needs?

Depending on how much power the amp requires, that 12V power supply might not be that cheap. The cost of a high-current power supply able to drive a car amp requiring 20A (or more) might cost as much (or more!!) than a powered home system subwoofer. I have a Yamaha sub (dual 8" subs with a intregrated 150W amp) for my home system that I paid $200 for two years ago.

be careful when you do that, because a home system runs with 8 ohm speakers. those sony's are 4 ohms each. if you hooked them up in series to create an 8 ohm load, then you would be fine running them off the home amp (as long as you have a crossover and enough power to drive two subs).

Er, hope you're being sarcastic, otherwise I suggest you start paying more attention in physics class!

hmmm i always thought that 22Khz was the highest an human could hear, i'm just wondering who or what could hear 100mhz....??

100mhz is like

100.000.000 herts
the human ear goes from uhm...20 to 22.000 hertz something like that if i remeber correctly...

anything above 300 hertz can potentially damage your speaker...
