Does anyone know of any good installers in the Peoria, IL area? I have 2 Crossfire 1000D's and 2 12W7's in the back of an F-250, but don't should as good/loud as they should. I called and spoke with crossfire's tech. department, but that wasn’t much help. Instead of going through the output of the master amp, they have me going through the invert jacks to connect the two amplifiers with a single RCA. I asked the guy why I couldn’t just go from output to the input of the slave amp, and he had no idea what the output was even for!?! Any help would be great!

You have to use the output from your master amp from your slave amp, they have the manuals on the site showing you how to strap those amps. With a litle over 1000 watts per amp you would almost be better running only one sub at 1.5 ohm on a strapped pair of amps vs both subs. Those subs need power to move.

That is what I currently have, with the first amp set as master, and the second set as slave. master amp pounds, slave does nothing. The slave will only work when going out through the invert RCA plug.
The recommended power for a 12W7 in the manual is 750W, so I assume they should hit really hard, epically in a pick-up cab.

going out the invert on the slave? you should not have to run any rca's out of the slave amp, and yes the rca will have to come from the master to the slave, they are already inverted by the amp that is master.
Go to crossfires website and read the manual.
What ohm load are you showing the amps? 3 ohm strapped?
