my 6x9 sucks

last night i spent about an hour trying to figure out what was wrong with my speaker. everytime there was any small amout of bass, it would sound like i cracked the cone or something. so i unplug it and looked for a way to take it off. i see the nuts, and go get different size wrenches to unscrew them, 1/4 inch 5/16 inch and 8mm all don't work. so i get that adjustable one (don't know the name). anyways im kinda tall, and the trunk was bitch to get into, and it was a bitch to take all the bolts out, i thought i was just gonna take the speaker out and buy a new set later, but right when i pull it down, theres a fuking penny in there! ! ! bitch ass little brother must've put change in there just to see if he could make me mad or something. well anyways it put everything back on, and my fore arms were shaking from exhaustion.

btw does anyone know what tool i need to use to get those bolts off next time? what is the thick wire the hold the speaker, and how do i get it off?
