I built a fiberglass eclosure that is going in my Polaris RZR. It is going to house six 6.5"s and one 10" sub. Is there any way to run all six 6.5"s off one amp? maybe a 4 ch.?
Yep you can run 6 speakers of the 4 channel amp. You need to set up 4 speakers in parallel on 2 channels and use the other 2 channels for other 2 speakers - Remember OHMS law before setting up this type of set-up. Check the amplifier's rms rating/ohms before buying an amp. Compare the amp to the speakers you will beusing.
