First of all and obviously:
>A Speaker
>Some Cardboard
>Tape
>Craft Knife

Secondly:
>A small amplifier, i have a tiny amp (shown) which suprisingly is capable of supplying enough power for the Peerless 3.5" 60w woofer I used.
>Wire, any will do, I used standard black and red audio cable.
>Some decent tunes to knock through the finished speaker!

 funny little peerless but i would think it would be more for midrange than bass.
also id use thicker card and extend the port sideways so its and L instead of a l thats how a real L-port goes. next step is a 12" in a MDF box? your mum would love that! lol. nice little project for when your bored though. but you should try a 12" or atleast and 8" in a wood box next! once you go big, you never go back!

 woah! from a 3.5"? better than a 5.25? Damn it must be good.

cool i was going to get a 18" 1800watt car subwoofer. what one were you thinking of? id tune it to low 20s if you have space that way you will pick up the real low bass in movies and songs and whatever else you play on it. i for 18Hz tuning you need a 6-8 CUBIC FOOT box!!! 

you should do an instructable of both of them. we need some decent speaker 'ibles on here and im too lazy :-P!

they have 8" alpine subs? never new that. i thought they only had 10"+.
damn thats cheap for a 18"! how many watts and whats the xmax? 
the one im getting is 300NZD so about 3 times more than yours its a blaupunkt velocity car sub at less than 1/3rd the normal price :-). i'll have to wait a while though because im getting a PSP atm (not the stupid GO ones, a normal one)
awww poor peerless :-(. yeah gravity sucks sometimes.
