I was guessing at some how plugging it into a remote lead, or using the wires that go tow the heated rear windscreen since they have broke off the window but i still have a switch for it.

Ive just made a speaker box for my new sub, but the back looked really cool so i put clear sides on the box. I want to put lights in it as well but not exactly sure how. As in id rather not just buy battery ones and stick them in, but I dont know what sort of lights i would need or how I would wire them up.

if you use a couple of LED's then these can come off your 'remote' wire, because they take very little power. if you're using a single LED (typically Ultra-brite = 2.2v 20mA) then you'll just have to put a 470ohm resister inline (there is a formula for calculating the resistance...but it's early morning, brain don't work!) or a simpler method for a group of LED's is put 6 LED's in series, they don't have to be right next to each other, you could have 3 one side and 3 the other etc. (2.2v x 6 = 13.2v) just make sure the LED's are connected correctly, at the end of the day they're still Diodes and electric only passes through one way.
There are other lighting options, but for a long-life, efficient, cool ('c) & rubust method...LED's fit the bill.

My box is about 1.5 cubic feet, do you think leds will be bright enough to light it up.
also (idea from brother) is it possible to wire them into the speaker wires so they pulse with the music...

yes, theres a couple of videos on youtube showing it but basically you wire them into the amp, im not exactly sure how to do it, but i can see it drawing some power from the sub anyway. but it s deffinitly worth checking out, it looks awesome.
but i would put them on a switch because they might get annoying if there flashing away all the time

you can put them onto your speakers, (i haven't got the time to do a diagram, so i'll try and explain). what you want is a small bridge rectifier & a linear pot resistor (50K should be OK). you'll have to take a cable from the speaker into the rotary leg of the lin-pot, take a wire from one side of the lin-pot to the bridge-rectifier AC-in. take another wire from the other speaker tag and have this going into the other AC-in on the rectifier. you should now be left with a '+' & '-' on the rectifier, take these to the LED(s). fully turn the lin-pot to maximum resistance, turn the speakers to as loud as you would typically play, reduce the lin-pot very slowly until the LED(s) flash.
There are other items which can be added to the circuit to stop the LED's from blowing & adding small capacitors to smooth out the flashing. but that'll just add more confusion.
You can do away with the bridge rectifier and have 2 LED's soldered together in parallel but facing opposite ways (?) so when the speaker is positive is lights up 1 LED and negative phase lights the other LED.
sorry for any confusion
