New Sound System (sum,amp,h-u,speakers) but Front Speakers not Working

[SCANDZ]

Hi Guys

Installed a New sound system yesterday. Used a mono block amp for the sub

[2LOUD2OLD]

have you checked that the speaker amp is turning on?
also check your fader isn't set to the rear

that's probably where i would start

check the amp is wired properly.

and you should not be running bass through stock speakers... high pass them at about 80-100hz.

could maybe loose connetions on either earth or at the battery
could have a short on the speaker wires, eaasiest is to test this with a multimeter
maybe check the RCA connections on the amp and at the headunit
