Hey guys


I managed to pick up a Rockford Fosgate EPX2 a while ago from someone on these forums. The original purchase was due to the fact my Soundstream amps dont have in built crossover functions (a Rubicon Picasso, Rubicon 5.2) As yet I have not found the time to install the EPX and I am unsure how much benefit it could provide. In my current setup the crossovers functions for the subs run through my Alpine HU (9815) and the speakers use the passive units supplied.

My main questions are -


1. Whats the main benefits of external processors as many of the top Sq cars seem to be running them.

2. Anyones opinions/thoughts would be appreciated.



Thanks

Heya,

The obvious advantages of using the external processor is that you will be able to run active. IE, you will be able to choose your x-over points for your mids and tweeters, and not be forced to use the preset values in your passives.
Another advantage is that, assuming your mids only have one input (they are NOT bi-ampable, meaning each speaker is run off a separate channel from your amp) is that you are able to use TA much more effectively. Running active and on seperate channels is the way to go, so you can change gain and TA on each speaker independent of the others.
You are also able to choose different x-over slopes for your speakers with an external DSP, which again gives you more tunability and flexibility.

There are other advantages, but these are the main ones I can think about atm.
