![Question](https://www.clublexus.com/forums/images/icons/icon5.gif)
ok, this may also be a repeat but... ive done a lot of searching on the forum and i cant seem to find a diagram to explain exactly how you do this... from what i have read i have created a diagram of what i interpret to be the correct way to install an aftermarket sub+amp to a stock HU... Please correct me if i am wrong... i am also unsure about wires, hence i have not done this yet... i want to see how hard it was to do this before actually carrying out the steps...
Here is a pic...
Thanks - John

You're only connecting ONE sub, right? In that case, you're making it a bit tougher than it has to be.
The amp power/remote wires are correct. The signal just needs to be tapped near the subwoofer, then fed to the LLC, then to the amp. Output of the amp then goes to the sub. All you really need to do is to use one channel of the LLC.

Even easier...just tap off the wires going to your sub. Literally just disconnect the wires that are currently on your sub right now and then feed them to an LLC. From there on, outputs of the LLC go into the amp, then the outputs of the amp go to the sub. ![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
As for the sub size and installation, you'll have to ask one of the SC members. I have a 2nd gen GS.

the is300 sedan comes with 8 speakers. i don't think it has a factory sub.
my sportcross has 9 speakers. the 9th speaker is the sub.
you can tap off one of the rear speakers and use a line converter to connect to your amp.

The SportCross features the same in-dash, single-feed, six-disc CD auto-changer and 240 watts of maximum power as its IS counterparts, with one additional surprise: a woofer mounted in the rear cargo area, bringing the speaker count to nine.

The Scosche FAI-3A is for use with factory Premium Sound, JBL, Mach Audio, and Bose systems. Can also be used as a common ground adaptor or universal speaker-to-line level convertor, such as when adding a subwoofer to factory systems.
