I already have a 1-channel amp hooked up to my two subs. But I was wondering if it was worth it to hook up my 4-channel amp to my 2 door and 2 rear speakers.
YUP...it will sound alot better.
louder and u can control the adjustments on the amp to get the best sound from your 4 speakers.....that is if their not stock...u didnt say if they were stock speakers or not
