Sorry I don't have pics, but yes you need a wiring kit.. i wouldn't use the crap they sell in walmart though. best way to go is find a reputable person on ebay selling rockford amp kits or something similar(dont go with cheapo brands).

Then installation is fairly simple. Power wire runs from your battery + terminal to the + terminal on the amp. Ground is simple enough, just make sure you find a good place to ground it to (preferrably using an existing bolt so you dont drill anything by accident)
the remote turn on wire(usually blue) on the amp, goes to the accy wire in the car (off the top of my head i dont know the color of the wire)

then obviously +/- terminals from the amp go to the +/- of the subs.


the only trick is, with the factory radio, you will need a 'line-output convertor'. also found on ebay for a decent price(unless you have a good private shop nearby). that will connect to your +/- of the factory speaker in the rear of the car(easier to get to then taking off the door panels). then the RCA cables that come in the amp kit run from the line-out convertor to the amp.




i know it sounds like a lot but if you take your time with it, probably take around an hour or 2 to complete.
