My experiment: Using car subs for my HT

So I had 2 10" car subs in a sealed carpeted box, a 2 channel car amp (~120w/ch) and car battery charger laying around. Since I don't have a RCA splitter at the moment I'm only using 1 channel on the amp since it's only a mono signal from the receiver. Both subs are connect to that one channel at a 2 ohm load giving about 160w total. I have it placed in the corner of the room and wow! I can feel every bass note through my seat.

I think it'll be even better once I get a splitter and bridge the 2 channels for a total of ~300w to one sub. My neighbors are going to hate me.

Can your receiver handle a 2 ohm load? If not be careful as you can damage the receiver/amp.

He's using a preout from his receiver to the car amp then to the sub. So there are no worries about the load.

What are you using to power a car amp inside?

EDIT: A charger is a horrible way to go! Very course DC (lots of AC ripple), no regulation and not enough power. 20A per 100W at 13.8V is what's needed. Clean power. I'm surprised you don't hear 80dB of hum. :laugh:

Plenty of power and safe. But your speakers may hate you! :p

It's been done a million times, and a million times it's a bad idea.
It will probably either kill your amp or your charger.
What brands of sub/amp are you using?

Rubycon - I used to have some smaller (of course) Samson amps, and they were really solid amps. That's quite a bit of power for $550, but I haven't bought any PA amps for a while.
