Anonymous | well, i looked at audiocontrol crossovers but their kinda high...limited $ what would be a good crossover for what i need??? |

Anonymous | the are RCA's, but the guys at Discount Car Sterio in WA said that FMOD are a piece of crap! are they just stupid or is there some reason for them to say that??? will the 20hz high pass work for me if i tune to 34hz??? |
