How exactly do you do it? I know you have to rewire the cables or something but I cannot find any exact info/directions on the process.

In nearly all cases, it depends solely on the imdependace of your subs, # of subs, and if they are single or dual voice coil.
EX. IF you have one sub, and it is dual 4 ohm, you would run it parallel (++, - - ) that would produce 2 ohms, then just hook your + and - into your amp, and it will be @ 2 ohms

 

the info 94lsboost gave you is correct but i thought i'd just help out and add that there is a sub wiring tutorial at jl's website. you can reach it at http://jlaudio.com/tutorials/wiring/index.html. there are even some nice pics.

 

No wonder it wasn't making any damn sense to me, I thought you could use it for normal speakers, didn't know it was just for subs.

 

well You can use any amp on "normal" speakers. You can even wire them in parallel or series to achieve a different imdependace. However if you run regular speakers @ 2 ohms, some cant handle it (heat up), and even if they do, they usually don't sound that great. They can be ran on a larger amp @ 8 ohms to reduce the power output tho, safely I might add.

 

Yeah that's what I was unsure about. On my amp it says it can run 2ohms @ 100 watts X 4 channels. Which would work perfectly with my rears and my new fronts, but when I actually looked at the specs on my speakers all of them are reccommend at 4 ohms. I was just wondering cause at 4 ohms my amp only puts out 75 watts X 4 channels, so I just wanted to get a little more juice out of the thing without buying a new amp.

I don't know if you are speaking about the amp or the speaker heating up - yes the amplifier will typically make more heat at 2 ohm then it will at 4 ohm but I doubt anyone could hear a degredation in sound based on the impedance you run the amplifier at. The increase in power will clearly off-set any small increase in distortion. Take a look at the impedance curve of any of your speakers and you will see that speakers are rated at a nominal impedance, and the impedance of the driver is constantly changing depending on frequency.

My mids and midbasses are 2 ohm drivers and they sound great!

That is sweet, I have a friend doing it (old school fosgate amps) on JL mids/tweets, and after playing for a while, if you have the windows up in his truck, you can smell the mids start to heat up. They also lose SQ as they go. I have saw this a few times, however I also know of people who run them @ 2 ohms effectively. I suppose it all depends on your speakers, amp, setup....etc, as with anything else.
