Well have you ever checked ebay for your audio needs? you can find some really good sets for little or nothing. i can guarentee that you will find top notch for under your $89 limit :P
look up... CarAudioShoppe....they are the people that just sold me my 600.1 kicker amp for $250(brand new sealed box), at the local stereo shop here they are asking $499 for the same exact amp!
Kicker 6x9'* for $60 too! just look man, you can get some cheap stuff, brand new too.
That is, unless you wanted to just buy somthing now instead of waiting a week....
Here, i just found these. check em out, $68!
