Do you have a car amp laying around? Are your gaming experiences too.... quiet? Do you have crappy-ass Durabrand PC speakers that snap, crackle, AND pop? Do you get the itch to wake up your neighbors? If you answered yes to any 2 of these questions, this guide may be for you! Ok, enough of the cheesy advertising. I've had this one done for a while, so I can guarantee if you do it right (and every part works), that it should all be fine and dandy. Things you'll need: 1 x Car Amp 2 x Box Speakers 1 x Minijack-to-RCA cable Some x Various other wires and cables Various x Tools A x PC Knowledge You'll need: A 200 watt car amp DOES NOT pull 200 watts (that would mean my entire PC is running off 50 watts) - I'm not sure what it does pull though, so don't ask. A car battery gives 12 volts, so does your PSU. If your doing this with an independent PSU (AKA, not the one in your PC), you'll need to connect wires 15 & 16 (green and the black right next to it) to get your PSU to turn on. I'd also recommend getting one with a rocker switch in the back, so you don't have to rig one in between 15 & 16. If your amp uses more than around 500 watts you'll want to use multiple molex connectors, because a single 14-gauge wire might not be able to hold all the charge needed for the entire amp, causing it to heat up and possibly melt. There is a method to the madness; if you unplug all your drives and your video card, you should be able trace all the wires back to 2 or 3 bunches (unless you have a modular PSU, in which I'm not sure how this would work), you'll want to connect the amp to as many bunches as you can. This way you're effectively dividing the charge on each wire (and sometimes making it easier on your PSU), if it works correctly. If you do two (or more) connectors on a particular bunch, your not gaining much because the charge will still have to go through the single wires that come out of the PSU, which is what you're trying to avoid in the first place. Step 1: Prep your PC Turn down the volume on the taskbar, and I mean DOWN to like 2-10%. Remove your side panel (unless your using an independent PSU) Step 2: Wiring up The Amp Connect the red wire (Positive) to the orange wire (Remote). Make sure that there's just bare wire at the end of all of the wires coming from your amp. Grab a Molex connector, you want the male end. Cut the Yellow (+12v DC) and the Black (-12v DC) right next to it, you'll want them as long as you can get (you can also remove the red and black if you want, but when I did it the Yellow and Black got a little shaky/loose). Connect the Molex's Yellow to The Amp's Red & Orange, connect the Molex's Black to the Amp's Black. Twist, tie, tape. Step 3: Connecting the Amp and Speakers You want box speakers (the ones that just have the - and + wires hanging out the back), if you don't have any you could try Goodwill (you can usually get them for like $20 over there). Connect them to The Amp. I'm not sure whether the - on the speakers really needs to be connected to the - on The Amp, but do it just to be safe (my speakers just have 2 nondescript wires, and they work fine). You may need to make them longer too. Step 4: Connecting it to your PC Plug the male Molex into your PSU, grab the minijack-to-RCA and plug the minijack into your sound card with the RCA connected to The Amp. If you have an amp that has more than 2 channels, you may need to move the speakers and RCA cables around to get the right ones. Step 5: Fine tuning Make sure all the wires are insulated good. Check them again. The last thing you want is your house up in flames, so check them once more. If your using an independent PSU, make sure it's plugged in. Turn on your PC. Adjust volume as needed (I did this with a 200 watt amp, and mines at 4% volume). Step 6: Make sure it's all up to par Play a game, more specifically, a really power-hungry one *cough* Bioshock 2 *cough*. Make sure your PSU is fine and running good. Other remarks: You could also hook up a car radio to your PC if you'd like, but I haven't done it yet so I don't have a guide. If your case is a tank (really heavy-like) you could rig up The Amp to your right-side panel, but mine's a lightweight, so again, no guide. If your using an independant PSU, you might want to remove unnecessary wires. I cannot recommend this as your PSU could deep-fry your pasty-white nerdy ass any day of the week. PSU vs. You = Dead You (and possibly cops). I have done this though (rigging it up for a friend ), so I won't say it's impossible. YOU MAY NEED TO ADJUST YOUR BASE. It'll probably be overwhelming. Try adjusting the gain on The Amp first, then adjust the equalizer in your drivers/programs next. IF YOUR AMP NEEDS A CAPACITOR don't ask me, I don't know what to do with it or how to rig it or charge it or do anything with it. Mine doesn't need one, so no guide.
