Adding Subwoofers to a Titanium

The problem as I see it is that our Sony sub is not just a sub. It is also the DSP. There is no sub feed from the HU. Also our system chokes down output the higher you turn the volume to keep distortion from blowing the stock speakers.

To get the volume / bass you are seeking, you need to eliminate the Sony sub and replace it with a good DSP + amp + bigger sub(s).

I haven't found a viable solution at a price point I'm OK with yet, but I'm still looking.

Id be interested in knowing if anyone has taken the sony sub part, and is it possible to replace with another 8" sub inside the factory box?

I would think its possible. I replaced the factory 8" sub that came with the audiophile system in my truck, but the SQ stayed the same. You need to replace everything to make an improvement over the factory sony system.

so NO ONE has put after-market sub's in their 2012 Focus?

Yes, they are out there, but I don't think anyone has added subs to the Sony system.

Do a search and let us know what you decide.

Yes, I have added subs to my 2012 focus, however it is an SE and without the sony system. The sony system is going to cause you much more problems than the regular 4-6 speaker configuration because of the built in amp/sub. You could just splice in an LOC and run that to add additional subs to run aside the built in sub, however you will want to be careful how much strain you are putting onto the alternator after doing this.

This is why it is not really recommended to adding aftermarket subs to the sony system, or any system with amps/subs added in by stock. You have to fully know what you are doing and what to order not to cause problems with the stock configuration. The last thing you want to do is add subs to it not knowing what your doing and cause hundreds/thousands of dollars of damage to a no longer warrantied sound system.

I would definitely get a professional to install at this point, because it is becoming more difficult than I imagined. Or I might just forget about subs altogether. By the time I got a custom box to fit well in the trunk and a professional installation and what not, it would prbably costing more than it's worth.

Your best solution would be run the leads going to the sub into a LOC, then into another amp, then to a new sub or better sub in the factory box. At least that way you will have some real power going to the sub, instead of the crap sony amp they use now that is rated at 390 watts total for all 10 speakers, and that rating is more than likely peak power. The RMS is probably around 200, then divide that into 10 speakers and you get like 20 watts per channel.

It would ruin the warranty on focus's with the sony sound system option. i.e. all titaniums. They have factory amps in them.
