yar w12prs is a great SQ sub. nothing wrong with it. that is for my other car (corolla)...i dont like putting heavy LOUD sound systems in a new car...rattles the $hit out of them...hehe. so no can do!
this is going to go in my trusty old charade...that is like my little boom box (but dont worry, i wont put any silly woofer boxes on the rear seat - the install will still be pretty stealth 
...going to upgrade its alternator (a big project in itself - since its a diesel engine, crammed space...so a challenge to install a bigger alternator)...
