Okay, this poor young misguided kid needs some serious help. I went to your homepage and I have to stop you before you do really gay things with your car.
1. Do not put those subs!!! good subs cost more than $18!!! With that said you don't have to pay an arm and a leg either. Most of the people on this site will tell you h ow to do things the best possible way. They often forget that some of us are ballin on a budget. Buy car stereo stuff used if you can, preferably from someone local so you can see and hear the stuff in action. You can save a lot of money and get good equipment that way. Wheel covers are lame, search the classifieds for one of the following
Stock 15 inch late model rims like the ones with the 7 spokes. You will get better handling with the larger wheels too and so many people have put aftermarket rims on their car that you can get 15" stockers for very cheap. Probably with tires too.
Stock 16" late model SVT wheels. I bought a set of these with tires for 400 bucks
Stock Wheel covers- It doesn't matter what kind of wheel covers you put on, anytime people see aftermarket wheel covers, they think " that is gay"
