Default 3 amps, 4 channels and 1 deck with 3 outputs.

I know this is a noob question but I need to know the answer...

Right now Ive got a 400.4 for my mids and highs with a set of components and a pair of coax running off of it, Ive also got my sub amp which is a T1500 wired paralell all hooked up to my deck with 3 sets of outputs which are all used and I need to add another amp for my rear fill which is a 200.2 with a pair of coax running off it.

Can anybody give me some info on the right way to install the new amp please?

switch the 2/4 switch to "2 channel"input mode and the T400.4 will use just the "front" RCAs to feed all four channels. [no, it's not a bridging switch]

then use the rear channels of your deck to feed the new amplifier for the rear speakers.

When switching the 2/4 to just 2, will I need to change any of the current wiring besides moving one set of the RCA's to the new amp?
And after moving the RCA's the amp will still get signal to all 4 channels?
Sorry, I feel like I should know more about this but unfortuneately i dont.

no other wiring needs changed.

just remove the rear RCAs and switch the switch.

then use the rear RCAs for the new amp

That's a lot of highs going on.

You won't need to change any settings or anything. I assume it's just grabbing signal from one set of inputs for the others in 2 channel mode. You just won't be able to fade the comps and coax. You'll only have L/R for both at the same time.

You will be able to fade out the rear coax though, which is good.

Does that 4 channel not have a set of pass through output RCAs? That would be easy.

So the 4 channel amp will now get front signal to all the mids? (2 tweets *passive, and 4 midbass)

I dont believe the T400.4 has pass through output, as in daisy chaining right?

you don't need an output because the switch take care of that.

Doing this, will it still allow you to use the crossovers on each channel still?
