Setting a PAC ROEM-VET1
Ok so I did the usual HU upgrade while leaving the Bose system intact by using the PAC ROEM-VET1. After putting things back together and adjusting the EQ to try and get a decent sound I found there was nothing I could do to get the highs to come out. It sounded like crap!
So I searched the boards and found I'm not the only one. I saw explanations ranging from: it doesn't use the tweeters, it bypasses the DSP which adds highs to the sound, it works just fine, install new 3" speakers and it works, etc.
Today I pulled it all apart and started messing with the adjustments on the adapter. Here are my findings for those who walk this path in the future:
1. The rears are unaffected by the pots
2. Only the front sub woofers are adjusted by the front pots.
3. The tweeters are controlled by the HU
4. The initial pot setting has the subs CRANKED
Thus the reason the sound sucks is because say at volume 10 the subs are at 20 and the tweets at 2 (simplified, yes I know, but the point it there). So what I did is:
1. Adjust the fade all the way to the front.
2. Turn front pots all the way down (no signal to the subs).
3. Turn up the HU to hear the tweets.
4. Start turning up the pots to add bass.
5. Fade back to center.
FWIW I found 12 o'clock to work well with some EQ on the HU. I hope this helps people in the future!

Knowing what I know now I would have left my stock HU in.

Upgrading heads up
Hello!
I'm searching for some tips on installing this PAC ROEM-VET1 interface. This one is very valuable!
When I purchased, I was thinking it would be PNP... It hasn't been delivered yet, and I'm thinking about keeping the stock CD player...
