Need help tweaking my tri-amp setup with DCX2496

[Mike82]

I recently bought a DCX2496 unit to tri amp and use a active x-over. All I can say is wow what a difference. These are my specs:

Amps
Parasound HCA-855A 5 channel
Crown CDi 1000 2 channel

Pre Amp
Sunfire Theater Grand 2

X-Over
DCX2496

These are a few things I am not sure how to acheive.

1. Being I need 6 channels for my right and lefts I need to use 1 from the crown which has 500watt at 4 Ohm compared to 125watt at 4 Ohm. How do I know I am feeding equal power.

2. Also I have a 3.5 way setup (The Mini Statments) I didnt feel like spending 8 channels on my right and lefts alone so I put the bottom two 8Ohm 7in drivers in series which makes them 4 ohm load. My tweeter is 7 Ohm and my mid is 8 Ohm and they are all different SPL. Now how do I balance all this as far as knowing how much power to give each driver. Or is all this just done by ear or is there a device that can acheive this?

You tweeter is best on a passive circuit with the midrange as it takes very little power to driver.

Outside of that your top and bottom crossover should be around 350 hz which is nearly equal in power needs on both sides.

Then your subwoofer can be adjusted separately.

I'd set all my gains to about 1/2 and then configure the dcx eq. It will take care of the little differences pretty well and can even shelf filter if necessary.

I am actually swapping out the midrange for a SEAS Prestige MCA12RC it can handle more power and get louder than the Tang Band. After going from passive to active the main thing I noticed was the music sounds alot more live and snappier. I could put the tweeter on a passive but I have more than enough channels for them to use I just bought a Adcom GFA-7605 with 5 more channels. Could not pass it up got it for 150 dollars its a 700 dollar amp new. I guess the main thing I was wondering is would I use a SPL meter to help syc everthing. I already know my crosses just want to know how to dial everything in.
