Default I did but -

non-nav, symphonyII here:

It is a massaged signal. At higher levels the stock HU cuts the sub so it won't clip. At low levels you get WAY too much bass compensating for it.

I am still looking for a better way to do it. I don't want to invest the $300+ into a JL cleansweep (which may or may not work on *only* the sub) or the RF 3sixty (simmilar product)

If someone finds, or knows of, a better way I am interested too! I'd be ok with tapping to the rear signal going to the amp if it will give me an uncorrected signal for the sub - but I havn't read that it will, or tried it :/

How about a hi-lo converter behind the stock HU? That seems like the other option.

Default Is the signal still 'massaged' though / loss of rears?

... or can I put the high/low just before the amp and not run (long) RCAs


(lazy yes)

Default The way I did it in my GTI was with RCA's to a hi/lo behind the HU

But I don't have nav or premium sound.

Default That's exactly what I did.. One problem though..

Well, more or less. I cut the wire to the factory sub and used a butt connector to join it to a high-level to line-level converter and out to my amp and sub.

Sounds fantastic with the Bose stereo, the only thing that drives me crazy is that in my '06 w/ premium sound+technology the auto-sound level adjuster which uses a microphone to sense background noise as opposed to vehicle speed with svc always wants to limit my max bass when I hit around a "20" volume and crank it up when the main volume is low say below 10.

SVC could at least be disabled. This "feature" can't and even says so in the manual and it drives me nuts that I'm forced to have it on all the time. Lame lame lame.
