I installed a Sherwood 105w/ch. reciever on a zoned audio condo. There are 4 pairs of speakers and 2 dual tweeter speakers installed. all speakers are proficients. the outdoor dual tweeter speaker has super low volume and if you turn it up all the way it will trip the protection on the amp. All volume controls (russound altx) have the jumpers set correctly. WTF, what gives? Thanks. CDC
