I'm trying to determine whether I need to install bass blockers or not. I'm installing alpine 170 a & 460a. I have a powered sub. There is no other amplification other than the sub. I'm hoping for good overall sound. Nothing mind numbing. Thanks...
bass blockers are ALWAYS a good idea... they allow you to not only stop distortion from crappy signal sent from the head unit, but if you ever do add an amp on the highs you play the highs alot louder without blowing them if there is no bass being sent to them
