Can You Use Subs On Computer?

[aquariuz6]

Hi guys,

I was just curious to how can you hook up subs onto a computer?

Is it possible? I imagine you would still need an amp, I wonder if you can use the one in the car?

The reason is I have old Fusion amp and 2 x 12" subs here lying around at the moment.

Just curious if its possible... or maybe atleast hook it up to dvd player or something.

Any ideas?

Cheers

If you check out Jaycar they used to have dedicated sub amps that would match up nicely, I think they still have them... I have one of thier 350wrms units powering my home sub, it breaks things

Thanks, you wouldn't happen to have a link to the amp at jaycar would you? Sorry don't really understand how these things work... thats why I got a professional to install mine in my car.

Can't I use the fusion amp?

Mind you I don't really want to burn or blow anything in the end.

Also I just want to avoid spending more money.

Just thought if it was possible to use them

Best to use a dedicated 240v home amplifier, here is a link.

Please be aware that that your subwoofer is 4ohm, so you could be generating quite a bit of heat from this amp (check that it's 4ohm stable).

If you wanted to use your fusion amplifier, then you'll need a 12volt convertor.

You're better off using a set of purpose built home computer speakers like Logitechs. I have a set of Yamaha 350wrms computer speakers, they cost around $300 at the time of purchase and they pump nearly as hard as my single 12 in the car at the moment.

If you can afford a decent powersupply, you can just use that to power your existing amp. 240v -> 12v

You would need a pretty substantial power supply (read - expensive) to power your fusion amp, your best bet if you want to use them with your puter' is buying one of the jaycar amps like Howie found and getting a 3.5 mm splitter and a 3.5 to rca lead - they can help you out with these at Jaycar (cant tell I used to work at Jaycar eh?)

a 40 amp power supply should do the trick and they are available from car audio distributors for anywhere between 450 and 2000 dollars.

One thing to think about to is the level the amp will see. Your computer from a set of rca style outputs will only have a weak signal output, probably less than 1 volt.

A car audio amp is designed to see between 2 and 8 volts generally.

so you will need to run a line driver, car eq etc to boost up the signal before it goes into the amp, otherwise no volume.

Or...

Go to Jaycar, buy the piece of crap amp, wire your 2 subs at 8 ohm so the amp does not shut down and you have bass.

This is the easist most cost effective way to do it.

if you are going to use it at home then buy a sub-amp for home (240V)

this will eliminate the 12-13.8VDC power supply.

only buy sub-amp as it would have a built in low pass filter.

do not buy a home theatre or a standard stereo amp as it will be a waste of time.

the line level coming from your PC will be in the form of 3.5mm stereo socket (earphone type) is perfectly fine at 1 Vp-p (standard). just buy a converter lead to go to 2 RCAs and you will be fine.
