If you folks have any questions about the car please feel free to email us.
One question I did have - when you replaced the Alpine with the Kenwood head unit, did you also have to replace things like the satellite radio and/or GPS antenna? If so, how hard was that?

As for the subwoofer, the only way to really improve it is to do something like we did in the youtube video. If you guys have any tech questions concerning the audio system please let me know as we went through that complete car. [email protected]
Soundsfast,

I would appreciate some quick directions on disassembling the back seat to get at the sub. I am thinking of the JL XD400/4 amp and sealing the enclosure as you did without at first changing any drivers.

How about the stock desk drive the tweets only sans crossover, and the JL running the midbass drivers and sub?

To anyone doing this, don't forget the JL Audio Remote Level Control (HD-RLC) for the sub! A working sub needs a physical adjustment knob.

I really apologize for the late response to this post. Some of you have have contacted us directly with some of your questions. To the question about replacing the nav system, yes everything except for the reverse camera has to be replaced if you want to keep those features. The factory Sirius antenna and tuner can be used but you will have to change the interface that goes between the deck and the tuner. We also just had something pop up with the vehicle we did. The vehicle ended up having a very small amount of engine noise when we got done. After three days of trouble shooting we found that the factory installed antenna was not grounded properly so we installed an aftermarket amplified antenna and the noise went away. So keep this in mind if you decide to do any amplified audio upgrades. If you have any other questions please feel free to contact us at [email protected] or through our web site at More Than Just Music | Sounds Fast

Thanks for the research and effort.
On the one hand, it seems like the problem fix should certainly be a Lotus responsibility--on the other hand, I personally see little or no need to be able to play a video DVD so I would not pay to get it fixed.

I also have another problem with the sound system, though, in that there is no output from the rear speakers. Hopefully, this is just a missed connection that can be sorted at the first service.

As for sound quality, other than the rear speaker problem, I think the system sounds pretty good and is a nice complement to the generally quiet interior.
The dealer confirmed that there was a problem with my head unit and replaced it during the first week of August. Unfortunately, the replacement unit also has problems. The original unit has been sent back and I am currently waiting for answer on what to do next.

When I get an answer, I will post it here.

Just finished my upgrade...

Well, I copied some of what SoundsFast did:
  • JL Audio XD400/4
  • JL Audio W1 series 8" 4 ohm subwoofer
  • Sealed the sub box
  • Added Alpine IMPRINT processor

And the sound is incredible! If you did not order the IMPRINT option, you are really missing out. When I turn off the IMPRINT EQ curve, it goes right back to the cardboard, paste-eating sound it had from factory.

Dear Lotus: Make IMPRINT a standard part of the tech package...without it, where is the "tech"?

If you haven't heard, IMPRINT is a computer controlled and calibrated parametric equalizer with, I think, as many bands as it decides it needs...hard to tell from the spec sheet. It sets up just like your home theater, with a microphone and that THWIP! THWIP!! sound. When complete, it has a perfect, even time-adjusted, sound.

There are 3 choices for the EQ curve: REFERENCE (tried this, it is great), MID-BASS BOOST (crappy as all getout...skip this one), and LINEAR.
You can only try 2 curves at a time, so I will test LINEAR after I reassemble the rear seats, etc.

I can only guess that those satisfied with their stock system have the IMPRINT option, as it is night and day, well beyond what I could do with an EQ setup.

I ended up powering the fronts from the JL amp as well, per SF's advice.
I kept the same drivers, and they are now far from the milquetoast speakers they sounded like before. They rattle the doors, so I will next need to seek out some DYNAMAT and DYNASORBS to correct that condition.

Dismantling Evora's interior is an awfull experience! I plan to write up the specific steps for those that follow me. Let's just say I broke a few fasteners I had no idea would be there. (I think I found Evora's weight problem...each panel is attached with 10x as many fasteners as would be needed to secure it. :panic:) Many time I found myself saying: "Now this is the hardest thing you will ever have to do to get this car apart."

On the bright side, the seats come out easier than Elise/Exige, and re-installing them is a simple process of lining up the tracks with 4 giant washers at each end. No crazy "T-shaped thingies"...you know what I mean. With a fixed roof, you have to fold and rotate the seats backwards to get them out the doorframe.

The whole operation took about 2 weeks (it is 100 degrees down here every day...I can only last about one trim panel's worth each visit to the garage), and I just now backed out of the garage to test for alternator whine. There was none!

Let me give a quick road test review of backing out of/into the garage:
"This is such a great car...such a smooth running engine, transmission/clutch feel great. It literally blasted back into the garage, but had more than enough braking power to handle it. It is by far, the Best Lotus Ever!"
:shift:

PS: The Chinese-built Alpine "amp" that powered the old sub is hilarious. It does not even exist at the Alpine website, and it's punyness goes beyond the pale.

Added Alpine IMPRINT processor

Notorious L.R.G.,

How much $ is the Alpine IMPRINT processor installed? I think it was a $1400 option, I did not know you could add it after the radio is installed in the car at Lotus. I could see maybe considering it,if it is not crazy $.

The Alpine PXA H-100 IMPRINT processor is very inexpensive. The labor to install it will cost a lot more than the hardware itself unless, of course, you're capable of doing the work yourself.

I paid $150 for mine on Ebay. PXA-H100 & KTX-H100 are the part numbers for the module and the required tuning kit. Sold together for the best price...not sure why they are sold separately.

PXA-H100 adds 4 volt pre-outs, another bonus when amplifying.

I thought it was a $500 option, but not sure.

The hard part to the install, besides the trim panels from Hell, is that the Sirius module is installed somewhere up inside the dash. If you want to keep the Sirius (and I did not), you will have to get the dash apart better than I did to retain that functionality, as the IMPRINT must be at the end of the AI-BUS, after the Siruis module. I simply pulled the Sirius plug and plugged in the IMPRINT.

Thanks for the info, I will ask Galpin (my dealer) about a price. They do sound install work as well.

Size matters:

Here are some shots I took of the amps and subs before the install.
(I farmed out the sub rebuild...they did the sealing and dynamatting, and somehow redid the ABS plastic on the front to suit the JL.)

But they were too big to really do any good here. Useful later, but for now I needed something small and plastic with a 90 degree grip:
(So I cut up some DVD covers...the ones with the hole worked especially well.)

The order I was told was to pull the 2 left side clips first, then work over to the right and top clips. In the end I had to "cheat", and removed the drivers side knee bolster, which gave me direct finger access to the lower left clip. I essentially squeezed it from behind the dash as I pulled, and that finally got the first clip to let go.

I'd like to say the other clips get easier, but not so much. As an angle develops, you have to guard against cutting the leather. Probably best to put painters tape on before you start. (I did not, but as things got rough, I wish I had.)

At this point, it's just 4 obvious screws to remove the radio.
(No helpful photo required.)

Once loose, it needs to be pulled straight out. There is a plastic nub screwed into the back of the radio that fits into a slot in the dash. This may hang up a bit, but if you wiggle it, and pull straight, it will come out.

At that point, you are faced with a hundred connections on the back. A very busy radio. Refer to your PDF that came with the car (or look it up at Alpine.com
http://vault.alpine-usa.com/products/documents/OM_INA-W900_EN.pdf

Here is where I ditched the old subwoofer out cable, disconnected the Sirius, plugged in the IMPRINT to that same plug, and cut and spliced into the speaker wires. The original plan was to go into the kick panels, but the magic of Lotus interior assembly goes beyond my capability at that point.
I had removed lots of pieces, but it seems the entire glove box, everything below the "color band" must come out to get at those. No thanks!

Getting to the subwoofer...

First comes the passenger side sill cover. There is a king's ransom of Velcro fasteners under here, and 2 pull type fasteners, one at the rear, and one halfway down. The front of the sill cover has a metal guide slot that grabs the kick panel, but this let's go without a fight.

When I reinstalled, I removed the long Velcros, and omitted the pull fasteners, to make the next trip in easier.

Passenger seat removal

Four 6mm Hex/Allen head bolts secure the passenger seat rails at the four corners. Remove these without fear, fold the seat, rotate counterclockwise until the headrest can be angled out the door opening. The Evora seats are 2x-3x heavier than Elise, so be ready with some muscles.

Removing the seat gives easier access to the rear area and allows more creative running of cables underneath. Space is TIGHT in this car. The bottom of the seat brushes the carpet as you slide it up/back.

Rear bench removal.

OK, the bottom seat cushion is just Velcro'ed on, so peel up from the far side and remove. Easy.

The headrests must be pulled off next. They also love their job, and do not want to let go. A photo of the backside will give you an idea what you are fighting here. 4 clips attached to two horizontal rods in the seatback. Pull/push upward.
(Some will fall off as you remove and remain on the rods. Re-attaching them to the plastic is a bit of a pain as well.)

The bandage is due to an incident with an exacto knife while running the power wire. (I only got to photographing these pieces after the wiring was finished up.)

Once those are off, the rear cushion is not bad, two 7mm nuts on top (under the headrests) and two 8mm bolts down below.

Rear window trim...

Next up is the rear window trim. It is secured from behind with 4 clips, like those from the dash. Trick here is that the bottom of the panel is tucked under the rollbar, so it is more of a pull/rotate downward towards yourself.
Then, once free, lift clear of the rollbar.

Those trim removal tools would come in handy here. All I had at this point was the white one, so much swearing ensued. The blue ones would pop it off in a jiffy.

Now for the passenger side panel over the sub...

To get to the goodies, you now remove the four 4mm Hex head screws, 2 along the bottom edge, and 2 along the seatback edge. There are also 2 clips behind the panel, one mounted rear high up near the roofline and one just under the window. Pop those 2, and wiggle out from under the seatbelt anchor.

Removing the seatbelt is optional. I did not want to disturb the glued in cover on the floor of the car, so I left mine up, and just slid the panel over to the driver's side of the car for the duration. The seatbelt anchor is a T50 torx head.

The subwoofer comes out first, with four 8mm screws. It is worthy of note that the top 2 screws are longer than the bottom 2. (Unless I got it backwards. they seemed to go back in easier that way.)

You will find the amp and the reverse camera module behind the sub.

More 7mm nuts, two above the amp, two below, and a single 8mm nut at the bottom, under the camera module.

The camera module will be relocated under the seat panel. Clip a few zip ties to get things moving around.
