View Full Version : bass blocker question

07-22-2010, 10:04 PM
i just installed PAC BB-4 bass blockers to my front speakers.
Frequencies Blocked at 4 Ohms: 0 - 1.2 kHz
Frequencies Blocked at 8 Ohms: 0 - 600 Hz
they work really good but when i try and go past the vol. that i could befor the spaekers cut out. is it beacause i need a pair for the rears or something else.
it told me to install them close to speakers but i put them in back of the HU. didnt have enough time to take door pannels off.
