OMG... I am so fed up with this project. Every time I talk to the guy at the audio store, he tells me that my ultimate goal has been becoming more impossible but it hasn't changed???

That's why I went to a shop, so that I wouldn't have to think, and learn so much about this project. It' really my goal to just enjoy my car, hear decent music quality, and stream BT from Pandora.

I found dual coil subs but they are 4 ohms.

I found a head unit, but im told the fader might not work with the stock amp because the stock head unit has no fader.

I found speakers (Infinity) that will replace the door speakers, but will they sound better?

Im ready to just buy a BT speaker and velcro it to the back wall of the xfire and call it a day. Just need to run power to it so it stays charged and I'll be done! I have a 25$ BT speaker from polaroid that sounds better then the xfire stock sound system!

SO if I could have 1 wish... I wish I knew which after market amp will power my new dual coil subs, the infinity speakers I may use to replace the door units, and support the new head unit and allow for fade and micro adjustments of the sound.

The guy at the sound place couldn't answer this question.
