Amp setup?

Hey everyone!

I just bought a JBL BP1200.1 amp to go with my Polk/Momo MM2104 (for now) and had a question about wiring it up.

There are two RCA inputs, marked front and rear, on the amp even though it's a single channel amp.

Here's what it says in the manual:

The BP150.1, BP300.1, BP600.1 and
BP1200.1 are designed to provide con-stant
bass regardless of the position of
the source unit’s front-to-rear fader posi-tion.
Use of this feature requires that all
four inputs are connected to the source
unit as labeled on the amplifier (front,
rear, right and left). If your source unit
has only one pair of RCA-type output
connectors and a pair of speaker-level
outputs, you may connect the RCA out-puts
to a pair of amplifier input channels
(front or rear), and the speaker level out-puts
to the other pair of amplifier input
channels. If nonfading bass is not impor-tant
in your system, connect a pair of
inputs, either speaker-level or RCA-type,
to either the front or rear input connec-tors
on the amplifier.

I do fade the music a bit, usually to the front, so where should I hook up my RCAs? Should I hook them up the the "front" RCA position?

interesting...never heard of that
do you have a dedicated sub pre out on your radio?
most of the newer ones that are over $150-200ish will have 3x outputs
1 for the front
1 for the rear
1 for the subs
im not sure about this, but i would think if you connected your rca's to the sub pre out, it would not matter
but truthfully
calling JBL would be your best bet
im not sure if anyone on this forum has had experience with that before

Thanks for the honest answer. It's rare to get something like that now adays. I'll check my HU (Sony ~3-4yrs old) and then call JBL.

Thanks again.
