Extended bag sound issue
for those of use that love our music, I need a little info here. I've installed 4 6x9's speakers in my bags. I have the Amps located in the bat wing of my SG. I've also change out the 5 1/4 to 6.5. I'm running all infinity kappas speaker which are loud and clear. My system has bass, mids, highs. I've add the same speakers to my buddies RK, but he has extended bags. There's no low bass only highs that will come through of the bags. Anyone with info on how to retrieve better sounds out of extended would be greatly appreciated.

They have to be wired positive to positive and negative to negative. If a speaker is wired backwards or a negative to a positive, you will lose your bass response.

yup, when an electrical wave goes to a speaker the speaker will move "out" and push a bunch of air the same shape as the electrical wave.
if you have 2 speakers side by side and they are not wired the same, one will push a bunch of air out...the other with "pull" a bunch of air back- at the exact same time and the same shape...so they cancel each other out.
most speakers are constructed so that a positive electrical pulse will cause them to go out, a few ( JBL) are wired the opposite. so if speakers from different manufacturers are wired into an array or system some thought has to be give to phase.
to check phase of a speaker, briefly touch the terminals of a 9 volt battery to the speaker terminals + to +.
speaker should move out and hold.
if it moves back, then it is "reverse polarity"
