Adding dash speakers

I have already added a complete system except for the dash spkrs. I like my phone and Nav coming out of my dash spkrs . If I order dash speaker plug-nplay from JRT to get them to play do I just need to connect that last pair of wires to the amp.
Or what is exactly required to get power to them after new ones are in place. I already have
Maestro, DSR1 and amp.

 

What HU are you running?
Is your system JBL?

I found after installing my Kenwood HU, replacing door speakers with Focals, and adding an amp, the system sounds better with the dash speakers disconnected.
YMMV..

Did James make your sub box?
Is 500 watts RMS enough to run those 2 10" subs?

 

Oh yeah, the system totally rocks.

JRT says the same, that the systems sound better with the fronts disconnected.

I also see guys that love the front dash speaker swap. I run service calls with this truck so I have nav and hands free going alot and they all worked in harmony from factory which keeps me safe.
