If your headunit has multiple pre-outs (3 to be exact) and your amp has (2) sets of line-ins and (1) set of line-outs, do you need to have both sets of line-ins on your amp connected to your headunit via the pre-outs?

Is this necessary, or just overkill? I know the line-out on the amp will go to another amp, the question really is how many line-ins on your amp must be connected?

Thanks

IIRC the differnt preouts are for seperate amps/processors... so it would be over kill... the output on the amp is for "daisy chaining" amps and processors.

awesome, just what I thought. thanks a bunch

The different pre-outs on the radio are for more then one amp (like one amp for your fronts, one amp for your rears, and one for the sub).

Intercooled T · 03-27-2007, 11:29 AM

understood, but why would the amp have two sets of line-ins, if it already has another set of 'outs' for daisy-chaining?

I haven't seen an amp with 2 sets of RCA ins? Are they label with anything other than line in? What amp is it? The head unit should be 3 sets, I one is for Front, one for Rear, and then one is for Sub...I can't see any reason you'd need to run more than 1 set or RCA cables...

Ok, I think i see whats going on...use the Ch3 and CH4 RCA ins, looks like that set is setup for a sub where CH1 and CH2 would be used for like rear deck speakers...make sure you use the sub out on your head unit...

LiquidFire · 03-27-2007, 01:08 PM

its a 4 channel amp meaning that to use all 4 channels you would need 2 left and 2 right inputs, hence the 2 sets of rca in's
like loserkid said ch1/2 would be for speakers since the crossover is only highpass and ch 3/4 is for the sub since the crossover is only lowpass
just make sure that when you connect the sub you use the ch 3/4 speaker outputs
