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

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.

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.

hope this helps :P

need any info let me know!!

This is what im running at home..

Sub-- Boston Comp sub in custom made box with jaycar module amp running 350 rms.

Check above link!! :huh:

to ad a sub to a computer u can buy a sound card then buy a seround sound package ment for for a pc

then you could probley buy a sub from a hifi place or connect a sub up with a lil wire mod

:laugh:

hope that helped

    • Can't remember the last time I saw a good, healthy battery dropping into the 9s during cranking,  Too many variables to say anything about it with any certainty though.  A float voltage of 12-12.2 is tired AF and given how AGMs handle high C rate and DOD, will just die faster and faster with each cold start.   
    • I find most vehicles dip into the mid to high 9 volt range, even with a good battery. Hitting the low 9s, and especially hitting into the 8s is pretty indicative of a dieing battery. The other part to look at is the battery voltage after the battery has been fully charged. They should be sitting at 12.8V, as lead acids are dieing, they head down low and lower. Often getting as low as 12.0 - 12.2. You'll start seeing this when the engine is cranking over slowly. Interestingly, depending on the vehicle, when batteries get really bad, you can see some REALLY funky things going on. From very low voltages, to higher than 16V too. Something I totally didn't expect! This part of the super low and super high voltages I've been seeing on motorbikes, I need to do some further studies on cars. I suspect cars will act a little bit different though for a couple of reasons.
    • Thanks! Supercheap has a sale on this weekend so might be a good opportunity to get a new one. I do have a decent multimeter so I'll give it a try either way.   Hah, you got me! I do not. All I know is that the battery holds charge and sits at an okay level before I start the car. Doing the full charge and rejuvenation cycle on a trickle-charger seems to not really make a difference to the cold start behaviour. I'll try and measure it during cranking and see what it does. It's likely terrible; it certainly feels terrible.  I'll be happy if it is really just the battery and I don't have to dick around with the alternator or starter motor.
    • how do you know voltage is fine?  quick easy test is connect DMM up and put it on max/min mode, remove fuel pump fuse, crank car for 3-5s, go check min voltage You'd be surprised how many "healthy" batteries are showing under 10v during this test in cold weather. 
    • Not properly. You need to be able to dissipate 100 amps or so to doing it meaningfully. You can do it indirectly by watching to see how far the voltage falls during cranking. Unplug the coils or something else to prevent it from starting so you can get a good couple or three chugs. It also helps if you have the multimeter set up reading before you start, and that it has max/min functions. So you can catch the real minimum without having to watch the screen, which often doesn't update fast enough to show the real max/min in dynamic situations. Or use a digital oscilloscope, which can be obtained for <<$100 from Aliexpress (although I'd argue for paying up to ~$200 for a nicer one). A >4 yr old battery will very likely be well down the path to the knackery. Many only last 5-6 years these days. The cold weather lately will definitely make it worse.
