That wire should work fine unless you have a very expensive setup or have to run the wires very long distances.

You shouldn't need any tools but a wire stripper like this will make it go more quickly. This is just to shave the ends of the wires.

Sorry for the late response hah.

It looks like you'll need an amplifier, just run left and right speaker outputs on your amplifier into the left and right inputs in the sub, then hook the smaller speakers to the speaker outputs on the sub. [Here's a video on that:] (https://www.youtube.com/watch?v=3zFs8uSZsCc)

Your amplifier (or receiver as they're many times called.) won't be as crazy as the back of that guy's, but the speaker hookups will probably somewhat be the same. Unless you get one that has RCA style speaker connections. Those are found a lot in older receivers though. Everything is color coded.

As for wire that's not to difficult at all. [Here's what you're looking for] (http://www.amazon.com/Mediabridge-14AWG-Speaker-Wire-Feet/dp/B00I8V8YE2/ref=sr_1_14?ie=UTF8&qid=1452545344&sr=8-14&keywords=speaker+wire)

Any thing labeled speaker wire will probably do. Higher quality stuff is thicker, meaning more copper wire inside, and has better rubber insulation on it. Wire thickness is measured in "Gage" The lower the gage number the thicker the wire. So 2 Gage wire is thicker than 14 gage wire. I know it seems backwards haha.

The spool of wire I linked is about 50 feet long. You may not need that much, or maybe you'll need more. You'll want to plan where you'll put your speakers before you buy the wire to make sure that it's enough. You'll be surprised at how fast you go through it!

With that large spool you'll make multiple speaker wires at whatever length you need. A pair of wire clippers cuts through them pretty easy. You'll also want a pair of wire strippers to cut the insulation off of the end, but not the copper wires inside. Need wire strippers? How about a clipper for when you need to cut through the whole wire? [Here's a cheap pair that combines both.] (http://www.amazon.com/TEKTON-3775-Electricians-Combination-Tool/dp/B000NPUK2A/ref=sr_1_9?s=power-hand-tools&ie=UTF8&qid=1452546538&sr=1-9&keywords=wire+strippers)

You can probably fine speaker wire and strippers somewhere locally too if you don't want to wait for shipping. Hopefully those links will let you know what you need.

Those wire strippers I linked have holes in the middle with numbers next to them. If you buy 16 gauge wire, place the wire in the hole labeled 16AWG, if you buy 12 gage wire place it in the hole labeled 12 AWG clamp down, and pull. It'll strip the wire nice n clean. I used to use scissors before I had one. Strippers make things so much easier though. It's really hard to carve off the insulation with a pair of ruddy scissors.

It's a lot to figure out at first, but it'll be worth it! Having this knowledge is a good thing for the future too. Installation companies charge a lot where I live.

That would be a great place to start building a set from. I only suggest that you get some speaker stands for your new speakers to get them to the right height. Don't forget the optical cable to hook the TV into the AVR unless you plan on running the cable box into the AVR with an HDMI cable. Also if you don't have one a stripping/crimping tool can come in handy for hooking your stuff up.

Sadly I don't know the type of connector this is, but would be interested to for other projects I have. I'm in need of some small in-line connectors like this.

[edit1] If I'm not mistaken though, it look like some kind of MOLEX brand connector.

[edit2] You could also just splice the wire and add an in-line extension with something like this. You can get them at any hardware store. These are the cripless kind and are a bit more expensive. The others you can get for a few $ if you've got a crimper.

This is one i usually use or similar but different brand: http://www.amazon.com/TEKTON-3775-Electricians-Combination-Tool/dp/B000NPUK2A/ref=lp_553398_1_6?s=power-hand-tools&ie=UTF8&qid=1418488304&sr=1-6

If you want to go a little fancier :

the nice thing about the second one is it will be easier to work with for smaller wires. The first is more of a jack of all wire strippers.

US here. sorry i
f you cant get these in Denmark.

Diy lm317 power supply. these things aren't the best but it is a linear supply and for hobbies you won't need anything more sophisticated. It's dirt cheap, and you get to practice soldering. Imo, buy 2 so you can supply the negative voltages for the common op amp.

Soldering station I have fondness for this station as it was the one we had to buy for our program at school. I like it a lot because the iron stand, heating element, sponge holder, and a solder wire spool are all connected so you just need to haul around 1 object. Don't need to go digging for your iron stand or setting your spool of solder somewhere and forget it. Works well enough for your use and I believe there are tips out there.

Breadboard and wires this is mandatory. If there's anything on my list you choose to buy, you must buy this first. Breadboards are essential. If you can buy two of these.

63/37 solder you don't work for a company that is rohs compliant, don't burden yourself with leadless solder. Look for a us shipping of that if you don't want to wait.

Wire snips if you own side cutters you probably won't need these.

Wire strippers again you might not need these if you are patient and strip them with cutters. Also the breadboards above come with pre cut

Helping hands I do SMD rework professionally and I don't use hands because I'm an idiot. Don't be an idiot and learn from the get go using these.

If you can find any of these for cheaper than I found, go for it. Should be around 70 bucks. Good puck!
