Has anyone added a sound processor to their amped infinity speakers? I've heard that the front speakers don't get full sound. I was thinking about replacing my speakers but I want good sound from them not just partial.

 

what kind of processing are you wanting? xover, equalization, stageing, timing,etc?

 

Yes, I have done exactly that.

I'm running the factory head unit (to look discrete to thieves, as well as retain cassette, am/fm, 6-cd, wma, mp3, sirrius sattelite, and steering wheel controls). I bypassed the OEM amp, and sent the audio signal from the head unit into a JL Audio Cleansweep unit. This unit does away with factory equalization, and gives a full-band, clean baseline signal to work with.

The output of this runs into a kenwood digital signal processor, to adjust equalization (10 or 14 band?), staging, sound fields, balance, reflection, reverb, etc.

Out of the equalizer into a 4 channel infinity amp, and a mono Rockford Fosgate.

The 4 channel goes into 4 seprate infinity crossovers, and then to Infinity Perfect component systems.

The Rockford pushes a JL Audio W6 in a hotbox enclosure.

All in all, it sounds pretty good...as good as any system I've heard that uses a factory head unit, and even better that a lot of systems that use aftermarket!

In addition, the JL audio cleansweep offers an additional set of RCA inputs, that you can use for about anything...cell phone system, laptop, dvd player, practicing your electric violin, etc.

That's what I was looking to do. Is to do away with the factory equalization and get a clean, full band signal. Would the JL Audio cleansweep still work the same if I don't bypass the factory amp? I don't want to have to put in an aftermarket amp. It doesn't have to be super loud. I just want very good sound quality.

 

I don't know for sure, but the factory amp does some funny stuff to the signals. If you've ever looked at a schematic of wires in and out of the OEM amp, it's clear that it's being used for more than just amplification of the signal coming in.

I know that there are crossovers of some type built into the factory amp. In the 7 speaker infinity system, the dash tweeters get the highs, the front door speakers get lows/mids, and the rear door speakers get mids/some highs.

I suppose you could somehow sum these signals together and then feed into the JL Cleansweep, but I chose to take the signal right out of the head unit in order to get a full-spectrum signal.

There is also some funny equalization done too, and I think it's internal of the amp, and not the factory head unit (because the bass, treble, etc on the factory head unit now has no effect on the music signal).
