User questions & answers

Question:	I dont care about the sounds i just need a bigger pa for my cb. Will this work with my cb
Answer:	Yes, your aux cord and your cell phone will produce music that can be heard down the block.
Question:	So, i just want a pa system for my car, do i need amything else besides what comes in this kit? how is the quality of the pa itself
Answer:	speak close to the mic, speak very close and you will be heard.
Question:	Is their any sort of wire extensions I can buy?? What type of wire does it use
Answer:	You can hook up 2 different speakers with no problems. A 100 watt, 2 - 100 watts or 1 - 200 watt the unit does not care. There are 2 speaker wires and a ground. it does not care if you use the ground from the unit or you ground the speakers to the frame. If you happen to get one of the units that only has 1 speaker wires it is easy to just split the power wire into 2 wires with just a crimp with one wire in and 2 out. do note that you will only get the same sound out of both speakers you can not put 1 sound on one and a different one on the other. It is really simple to figure out since the wires are clearly marked which is which. PLEASE so note that if you are using one of their speakers that are specifically made to this unit that the wires off the speakers proper are different colors than the control head (????) off the speaker proper it is white is power and black is ground
Question:	Can you use this as a p/a speaker on a cb
Answer:	I could be wrong, but I believe it’s a remote power wire
