I'm adding two my factory system with a new 4 channel amp to drive a set of 6.5" component speakers (Alpine type R) in the doors and a set of 6x9 coaxials (Alpine Type R) in the rear deck.
The signal I grab off the factory amp is already rolled off at points I know and to get a full range of sound I have to sum them. On the overlap point I'm sure I will need to use an equalizer to straighten out the hz range on the signal before it goes to the new amp.
Here's my setup - I need a recommendation on an equalizer that will allow me to tune this "summed' signal:
I took two signals off of the factory amp and run them through an Audiocontrol LC08 Line Output Controler and will need to eq that signal before it goes to my 4 channel amp which drives the door and rear deck speakers. The signals I am summing look like this: Front door signal. 0 - 100hz rolling off at about 120 Rear deck signal: rolls on starting at 100hz and from 120hz it's fully established and goes to 25k So.. when I sum the two I get 0 - 25k but that area between 100 and 120 is going to be a bit messy so I figure I need to use an equalizer on it. Any ideas on which pre-amp equalizer to use? Thanks.
