why not.. u can get a pioneer amp.. and matching pioneer 4 way speakers.. real clear and crisp.. technically.. u wouldnt NEED that amp.. u can go str8 from the radio to the speakers.. but it will sound much better.. with the radio.. u would only use about 1/5 of the potential on the speakers.. its on u.. do u like loud.. the pioneer 4ways or better also give a nice mid bass sound so it wouldnt ONLY be highs.. pioneer is relatively cheap compared to kicker and etc.. i would say go with pioneer amp and speakers.. then u would NEVER touch ur system again.. it would sound real nice.. ur look about about 300 maybe.. 100 on the amp.. and 100 for 2 speakers.. but u got 4.. so its about there.. i would do it..
