I got that info straight from your technicians mouth. Yes it will work but as he stated very clearly the less high range signal input the less restoration that takes place. If you fade off the high input reduces the level of restoration, I spent a great deal of time with the technician discussing this very thing.

If your technicians are not giving out the correct info maybe you could correct them? Anyway I don't care cause my RE-Q works great, and I don't have to pull the Bose amp apart again when I add more to the system. Your in the harness anyway just solder in the extra 4 wires and call it good.

With adding just a sub in this case, the sub is already eq'd so the frequancies needed are already there. If you were doing a sub add on to a stock 4 or 6 speaker set up then yes for sure hook up everything.
The way a ReQ works is it fixes the bass roll off that some OEM HU have, by sensing voltage differences and correcting them to bring the output back up, But because this is a system with a sub already there wont be any roll off on that channel. So if you are hooking up to that channel the only thing that needs to be "fixed" is the signal level.

So long story short the tech is right, if you have a non sub channel car, but with having a sub channel it's not needed, in this case.
And yes if you are adding to the system, as you are, hook up everything. But the OP just wants better bass.

Where could I get a custom enclosure? And the MTX Re-Q converts the speaker level signal back to line I take it? But re-eqalizes it to have more bass?

Ok that makes sense, why wouldn't you connect the full range input for a customer. Would seem to be lazy not too, only takes a few minutes and gives more output options to the customer. How about the smart engage will that work properly without the fullrange input?

If someone installed a RE-Q for me and I had to go back and get them to hook it all up that would make me very unhappy.

Basically yes. some OEM HU will eq out bass at higher volumes to protect the stock speakers, the ReQ fixes that so when you keep the stock HU you can still get a full signal to the amp. however on cars that have mids tweets, subs, ect if you are adding just a sub then you can get away with just useing the sub channe; as it hasn't been eq'd to take out bass.

Thats why the sales guy should find out the whole plan of said customer, other wise yeah it make for a pissed customer.

smart engauge will still work.

As for the enclosure you will have to get one built for it.

Does the re-Q convert speaker level to line level? Thats the part I need. Also ANyone know subwoofers that will fit in the existing spot on my roadster? I prefer to not have to build an enclosure.

Yes basically put the req is a converter, but it also EQ's.

I would not mind a road trip to or from where you are for a custom box install.

Can someone explain to me how to set the presets for the fm stations.

i'm lost:ughdance:

You need a Pro for that.:tiphat:
