I have (2)12" Alpine Type R Subwoofers and a JL audio 500/1 Mono Amplifier.The bass sounds alright but it overpowers my Bose component Speakers to a point where i can't even hear the lyrics nomore.So i need another JL audio amplifier that can power my Bose Speakers.do i need a 300/2,300/4,450/4,or a 500/5 amplifier?I am using a Factory Deck with a Kenwood Equalizer.
