What's in the car


Special Thanks to Jeremy and Paul for the helping hand in getting everything designed, installed and tuned!

What's not in the car

  • I removed the Pioneer Premier AVIC F90-BT Navigation head-unit--I was never a fan of this unit. I'll probably install it into my wife's Toyota Solara so that it doesn't goto waste.

Where we're going, we won't need headunits.

The idea is to replace the entire stereo and navigation system in my 2006 Saturn Ion Redline with the Motorola Xoom Tablet, a few amplifiers, new separates and sub woofer.

What I have on hand:


What I need:

  • Possibly new separates
  • Some sort of Mount
  • A clever idea and method to mount the Xoom into the dash without blocking controls and vents. Oh yes, and not look like an idiot with a computer in the car that's blocking half of the windshield. The tablet should be removable as well.

I ordered the RAM-HOL-TAB6U chassis and RAM-B-138U mounting arm from ram-mount.com.

I decided to go with a 12" Polk Momo in a sealed box. My TypeR and TypeX woofers took way too much space, and the wife insisted on keeping the spare tire :P. The sub is connect via spades so that it's easily removable, if needed.

The 12" Polk sounds amazingly powerful and clean.

I've got the system pretty well tuned. The primary input is connected to the Belkin Bluetooth stereo receiver, the FOUR.1 has an AUX button which its input is connected to a mini-jack cord that I've stuffed under a passenger console panel, for now. I'm planning on moving this to a female surface mount mini-jack for cleaner and easier access. The A2DP BT audio receiver sounds amazing with my Xoom tablet and Droid X phone. Also, the 5v phone charger adapter provides a super clean source of power for the Belkin BT receiver with absolutely zero engine noise.

I canceled my order for the Ram mounting chassis and arm and decided to build something myself for a few reasons. The Ram chassis is spring-loaded which didn't provide for a seamless way to remove/reinsert the tablet, it also didn't provide any means of connectivity. Instead, I purchased the Standard Dock and modified my existing metra dash kit. The dock gives me power and audio. Another plus is when the dock receives power, it turns the tablet screen on--pretty cool.

So far so good. The dock is rock solid during my test drives--no bouncing or shaking whatsoever, and the screen lights up with I turn the key on. The primary input to the AudioControl FOUR.1 is the hardwired line-out from the dock. The AUX input to the FOUR.1 is the Belkin Bluetooth A2DP receiver.

The only cost in getting the Xoom into the car was the price of the dock ($28.99).

So far, I haven't seen a need to add additional support. The tablet lays nicely against the dash face--I may however add more support for piece of mind.

We picked up a 1.8cuft sealed 15" pre-fab enclosure from a local stereo shop for a good price.

Special thanks to Paul for his hard work modeling the enclosure, radiator and driver combinations.

Massive amounts of excursion. This combination far surpassed our expectations.

  • Enclosure tuning frequency is 27Hz
  • F3 is 23Hz
  • Net internal volume 1.6cuft
  • 390grams "mms" of mass on the passive radiator


The video merely demonstrates excursion and the movement of the passive radiator--no justice in sound quality. This thing sounds amazing!

I wasn't happy with the Kicker KX600.1. The amp wouldn't make any power without the "bass boost" knob turned up. After setting the gain with the oscilloscope, the amp put a total of 532 measured RMS watts to my subwoofer. Not bad, but not enough.

You can't see it, but this is an awesome app. It generates tones from 20Hz-20kHz. The GUI hasn't been optimized for tablets :/

The idea of the new system

Rev 2

The RCA level knob will probably end up being a voltage divider to attenuate source 3.

The TC VMP passive radiator at 390 grams and the RE sEX10D4 is an amazing combination and sounds great--but I think I'm after something louder. Paul is using the Fi Car Audio Q series 15" and handles an amazing amount of power with ease, I may go with the 12" version. The 12" models well in BB6 with a nice hump around 45Hz, which I think I want. I'm also considering the RE sEX12D4 or the sXX12D4. The RE subs model much flatter and lower, so we still need to run through a few different models in different enclosures. The enclosure I'm running now was a POC, I believe we'll build something custom that spans the back seats and is hidden with a beauty board.


Also, after upgrading the sub amp (KX600.1 to T1500-1bdcp), I've measured 985RMS watts going to the sEX10D4. The RE sub handles the power like a champ without any problems.
