help installing Cadence acoustics 5 channel amp

[Cybrphantom]

so last night my new amp came in so i opened it up and began to replace the 2 channel i had bridged for my sub. i transferred over the power and ground cables then started to wire up everything to the sub. and speakers. i decided to run new 14ga wires from my amp to the speakers so i get everything wired up and only channels 1,4 and 5 work. i get nothing coming from channels 2 and 3. do you guys think this is an amp issue or wiring issue? Thanks

rca or amp issue try another set of rca's if same problem then its amp.

Do U have the input switched to 5 channel???

well the instructions that came with the amp said to put in on 4ch mode since my head unit only has 2 sets of rca outputs for the back and that the amps preamp circuitry would then mix the signal and i would have a contstant sub on. i know one set of rcas is good becuase thats wat i originally had running the 2 channel.

So your source unit only has one set of RCA outs or does it have front/back?

If it only has one set (one left and one right) then you need to switch the amp to 2ch input.

THE HEAdunit has two sets one for front and one for rear/sub

Then if you have front/rear you will use 4 channel mode. If the second set is only sub then you need to adjust that again as they sub channel will not be full range in most cases.

However, assuming you have a front/rear setup then you need to check your RCA's as that is the most typical issue.
