Re: Factory Frequency Response

The centre channel is always dominant unfortunately, especially with music which is mostly mono. Try a few different tunes to compare, and avoid the radio, satellite and any low bitrate rips you might have acquired online. Bust out a bought CD or some well encoded digital files.

I recall turning off "surround" directs a bit more to to the left / right... or at least messes with the sound less so it doesn't sound like the centre channel is doing all the work up front. Also check you have the fader to at least the centre, or preferably biased towards the front.

I don't love the system, but tolerate it when faded almost all the way forward, mid and treble at centre, bass somewhere between - 3 and +1, surround off.

Give it a try and let us know.

Cheers,
Steve

Re: Factory Frequency Response

Greetings,

On fixed system such as here with the factory premium system, the center channel is going to be the dominant one in the L/C/R (left, center, right channels) as member BARBOOTS indicated. Follow his advise on testings procedures. Mostly likely even the dealers's service tech's will not diagnose this correctly.

Most of the surround sound system both aftermarket and oem do not allow you to adjust the center channel as compared to some of the better home theater surround sound processors. The aftermarket JBL MS-8 can even give you a dominant center channel until is calibrated correctly. The Alpine aftermarket DSP PXA-H800 allows flexibility to adjust the center channel mix. Also the Arc Audio P8 DSP in the advance mode allows you to set a mix percentage for the L/C/R.

Sorry to say, their is no solution or work around unless you go the aftermarket route. For example; The cheap way out for this in the aftermarket world would be going with JL Audio 600/6 and feeding the L/C/R high level factory amp outputs directly into the amp's low level inputs via an RCA conversion cable (approx. $100.00 for 5 cables) and using the amps gain controls to offset the center.

As many of us have said here in the forum, correcting the factory surround sound system is not cheap. If you going to do it, prepare spend money.

Best for now.

Arrow Re: Factory Frequency Response

Trying to plan out a modest system in my 2012 & this bit of info eludes me on the forums...

To your knowledge,experience does the factory 506w system have time delay built into both the rear doors & the rear D-pillar 2" speakers? And if so, is that delay the same or different?
I'm trying to determine if I can sum those 2 sets together from the factory amp (using an AudioControl LOC) & still avoid major cancellations or do I need to spend the money & keep them on 4 separate amp channels just to keep the rear-fill sounding clean. My rear door speakers, whether I use coaxes or components (w/ the tweets going into the rear pillars), will definitely be on a multi-channel JL amp runining 50-75 watts per channel.

Thanks for your advice!
