JUst got the 4 Polk db speakers installed, and a Sony head unit.
Whenever I turn up the volume too high though, it will (head unit / speaker) shut off and turn back on, completely cutting off.
I am probably going to get a sub to take some of the stress off the speaker, but would it be good to also get an amp for the speakers? Would a sub that's already powered be better than a Polk sub with an amp ? Will this even solve my problem at all ?
