hi anyone heard a 407 with the factory jbl sub?
is it worth getting s/h or too tame?
would it be better doing a diy.....

Pretty sure the standard HU (from the few I've seen), won't take an external phono connector amp. I think the JBL one has a different connector.
So that would be pretty much your only option for the sub.
If you change the HU you are potentially in a whole new world of pain. Unless there is one that integrates into the car and provides the same level of access to the settings/options.
Although I am mental, and could be totally wrong.

YEP 407 stock HU wont work with subs etc you only have 2 real options remove HU and replace with aftermarket one but you will loose a lot of the ability to change settings etc or option 2 buy another 407 with the JBL system already fitted. I think it in the Coupes and X lines :D

or use an amp that can use high level input and run off the rear speaker feed...
still keeping the functionality of the rear ,it just provides the signal..
then the amp has an adjustable filter to feed power to the sub direct,
i just really wanted to know how effective it is,as an easy fit solution
anyone?

Isn't the standard HU about 10/15w a channel
I tried some upgraded VIBE speakers in my blue one, they sounded shit, I'm not kidding. The stock ones were a lot better in comparison.
Will that affect sound quality?

were you careful to make sure when you wired them up that the polarity was correct to ensure they were in phase with the rest...

Yep, I tried them both ways round. Then I took them back to Halfords. I only discovered why after I opened the packaging and read the installation instructions, The minimum input was 30w.
Besides, to be fair, the stock ones aren't that bad. I might try and get hold of the JBL amp and sub for my new one. There was quite a few on Ebay last time I checked.

yes thats where i saw one and thought it might be an idea to keep the boot clear,
but suspect like most stock stuff pretty lame and no woof..lol
but like you say, the fitted system's not a bad compromise..
not to say it can't be improved of course with a good selection of high end bits n pieces

The sub/amp unit is like this

It sits in the side panel in the boot.
Actually quite a nice solution as you lose no boot space, and don't have stuff sloshing about the place.

have you actually heard one though? in a standard install..or are the ya waste of cash?
I've heard one in a friends car, it sounded alright. Given he's 40+ (the crusty git) though it wasn't at ear splitting volume.
For me it would be ok. I do wonder how easy it would be to stick a better subwoofer in it. If not a larger one, maybe one with a better frequency response.
