Speaker question...anyone who knows this rules...

Alright, I want to know if I can do this. Can I have a car subwoofer, powered and enclosed, hooked up to like a home theater receiver? Only reason I ask is because I have a sub and amp from my car and I want to see if I could save like 400 bucks on a new subwoofer and use that one. Thanks to whoever knows if this can be done, people who know how to do it can get a cookie too.

Um, dont know much about stereos, but aren't car stereos 12V DC, and home systems are 110V AC? Hook it up and find out, I say!

(just have a bucket of water handy...) :cheesy:

Edit: unless you're in Europe, then you'd be 220V AC, of course.

I'd just hook the sub up to a car battery, that's not a problem. I just need to know how to run the connection from the sub to the receiver.

To begin, ignore the well meaning posts before mine.

Car subwoofers are normally "passive" meaning they don't have an internal amp. Thus, you have to have an amp to hook up to them. In other words, don't hook any dc voltage to them or you will either fry the power source, the voice coil in the speaker or both.

To answer your question:

I'm assuming that the sub you are refering to is passive (see above). If this is the case, you will either need an amplified sub output from your home receiver or you will need an external amp to power the woofer.

Again, whatever you do...don't hook any voltages directly to the speaker.

You will need a DC to AC convertor if you go 'directly' to the battery. Otherwise hook it up to the generator to get the AC. I would also bet that this is more than most people can do without some good amount of car/electrical knowledge.

I re-read your post and I see you say it's powered.

May I ask what brand/type of amp it uses? I repair audio equipment for a living and I've never seen an internally powered car subwoofer.

Anyway, you can buy DC power supplies that can handle most any current needs within reason. Of course, the more current you require, the more costly the supply will be. Or, if you were familiar with electronics, a regulated 12 volt dc power source would be a simple circuit to build.

There are acutally a number of powered car subwoofers, most of them Bazooka brand:

(I hope this link isn't against the rules.)

If it wasn't a powered subwoofer, couldn't you use a speaker-level input with a low-pass crossover? It wouldn't be ideal, but it might do.

Im using a Kenwood 800 watt amp 2 channel with my JL 12in W3V2. I talked to a kid on my floor on how to do this he said just use a battery with the proper wiring, which I have and know how to connect. I guess the main thing I was asking was if I could hook up the sub's wiring to the powered subwoofer jack on the receiver. I don't think it would be too hard, I just don't know how to do it.
