Hi all.
Although I dislike the stock HU, I don't want to swap it out quite yet. Thus, I've tapped the rear soundbar speaker wires with a line level inverter, but the sound is kinda crap.

I'm curious if I can tap the sub wires to the inverter instead as that won't have the low frequecies caped out of it... or so I assume...

I can't find however what's + or - or Left and right for that matter. No wire diagram I've seen has these wires.

The wires plugging into the factory sub are:
Grey/Brown
Grey/White
Green/Brown
Green/White

Would anyone know if this is possible?
And if so, what are the above wires channels and charges?

Thanks for the assistance. This site is great.
Kevin.

 

You tapped the soundbar speakers, and found that the head unit has a high pass filter, blocking some amount of the bass. Result... sounds not too good, lol... Meh... it ticked me off too.

And I suppose you are now considering the sub wires because... they are easy to access?

An idea.......... If you can't figure out the wiring for the sub, you should be able to use the wires from the front speakers; the frequencies aren't filtered in the front (except that high frequencies are sent to the tweeters; but that shouldn't be an issue; but I haven't had the time to test it on the front yet to see the results).

 

Ya, I wasted alot of time soldering wires to the soundbar, only to realize that the low freq is cut from it... jeez.
The "premium" system is crap.
I messed around with it last night and removing the 8" factory sub and taping it's wires proved to be much better.

PLEASE MAKE NOTE OF MY ERROR:
DO NOT TAP THE SOUNDBAR SPEAKERS FOR YOUR SUB/AMP IF YOU ALREADY HAVE THE FACTORY INFINITY SUB. Tap the sub wires or front wires mentioned in this post for your inverter.

Since the sub lines already have the high freq's removed, and are being boosted by the factory amp, it actually sounds not half bad... but it's still bad. Not nearly as clean as an aftermarket HU setup.

I live in a rough area and I always have my doors off so I'd rather not change the stock HU.

Thanks all!

 

Are the left/right signal leads from the headunit to the premium amp level-attenuated? in other words, are they dynamic with the volume knob position or are they constant signal level with volume being controlled at the amp via the digital connectivity? When I checked these it seemed that they were always full signal when on and off when the headunit was set at "0" volume.
