The Kenwood DDX9907XR Head unit is connected by using the RCA back and front music Preouts to your JL music JD400/4 RCA Inputs CH. 1&2 and CH. 3&4 and Kicker 46CSS654 kept & best door speakers attached to the audio speaker Outputs(CH. 1&2) plus the Kicker 46CSC6934 remaining & appropriate rear platform speakers connected to the presenter Outputs(CH. 3&4).
Really don’t envision i will change the OEM top middle Speaker(Boston 2 Ohm middle) because of the Kicker 47KSC2704 4 Ohm middle and then leave they linked to the OEM Amp side speaker output since OEM are 2 Ohm productivity. Your point above, i do believe this is the reason it really is higher when it’s connected.
From further analysis( it appears to be like… solution 1… i will place a presenter L-Pad Attenuator about positive presenter cable amongst the OEM Amp and also the latest Kicker 47KSC2704 4 Ohm Mid and employ the attenuator to fit the volume with the door speakers Option 2… add an indication processor into the program, this looks best but Really don’t know just what more I need to see and how to catch everything upwards. Option 3… acquire an alternative Amp that supporting the 5 presenter create You will find. Really does one even exist considering that the top heart speaker are a mid assortment presenter. Solution 4… another thing.
Hey all Farrell
Concern… the other selection perform We have for connecting the Kicker 47KSC2704 4 Ohm Mid inside brand-new program without needing the OEM Amp?
I love to getting cautious with terminology as otherwise could write misunderstandings or promote a few ideas which are not very precise. In this instance visit their website, it is critical to remember that there isn’t any this type of thing as a a€?truea€? center presenter if you don’t’re making use of an indication processor or acoustics sounds media that provides an impartial center channel signal source.
The problem right here is the center audio speaker have even more amount and power to they than each presenter, indicating you’ll need to decrease a reasonable quantity of electricity across a resistor to get the amount down
For instance, in-car sound processors Dolby professional Logic II can imitate a real center station [deriving center from music, not simply L+R mono]) when a DTS or Dolby online indication just isn’t existing. That’s how I utilized a center station myself.
What you’re willing to carry out inside setup are make a a€?center filla€? or a€?pseudo-center/monoa€? mono speaker arrangement. The article your associated with didn’t quite describe they the way in which i might has expected, as they’re mostly worried about just how to hook it up. AudioControl used to have an excellent white paper discussing precisely why L+R is clearly detrimental to stereo imaging but i can not find it, sadly.
Anyway, to suit your build there is many happening. Very to get at the a€?meat and potatoesa€? from it all:
a€? you need to use a 4I© presenter utilizing the OEM 2I©. It’s going to operate okay, with 1/2 the efficacy of a 2I© presenter. a€? you happen to be using both RCA and speaker-level signals consequently the amount may possibly not be correctly proportional in some instances. It is best to need just one or or even the additional, maybe not both alert type. a€? The JL amp is actually bridgeable, and exactly what could be complete is utilize tri-mode whilst was previously known as in older times. That is simply wiring one audio speaker in bridged form while 2 stereo speakers are wired one per station as regular.
I find *at least* -15dB is a good start, therefore you’ll need a some electricity resistors of fairly huge energy rank. Perhaps not useful, and they’re going to have hot at high power production furthermore. (Based on the things I bring checking using my presenter L-pad calculator right here.)
