did you set gains at all?

are all rcas plugged in?

have you gone through the headunit options and made sure there wasnt any weird options turned on/off

how much experience do you have installing such things?

 

[alpine7909]

the headunit is factory. what do you mean by set gains? the only gains i set where the gains on the amplifiers. is there any other way to gains like through the processor?

 

[The Camry]

Nope. Just on the amps. If your getting almost no sound even when its turned up. Sounds like your gains arent even turned up.

Start with that.

have installed such processor before? its a pretty complicated unit if you have no prior experience.

 

[alpine7909]

no i haven't actually

Yea, could be a myriad of things. Crossovers set totally wrong. Gains not up. Wired all wrong. i mean, no offense but you seem in over your head here.

Look for switches on the chassis of the headunit itself. The old Imprint required flipping small switches on the chassis of the head unit to divert the audio out to the external processor via the Ai-net cable rather than to the pre-amp output RCA plugs.

Remove the headunit and look for small switches on the top or bottom of the chassis and use a pic tool to select 'EXT'

Yes true, but if it was not on 'EXT', it would have no sound whatsoever. OP says he has sound up front but not in the back so I suspect something else is wrong.. Could be initially setup wrong with the rux.. I also suspect gains too low on front. OP are you sure you even have everything wired right?

Untrue. I have experienced it myself...a small bit of sound WILL come trough the RCAs (of the external processor) if the headunit is set to 'INT'.

Hey OP take a look at the chassis of your Alpine head unit.
