Purchased car in December 2010. The factory BOSE system licks monkey *****. Really muddy midbass, no clear highs and muffled midrange. Unfortunately I have the Navigation package, so I'm stuck using the factory source unit.

The goal was to have a really good sounding system that can get loud with minimal custom work.

Head Unit: Factory DVD/CD player with Bluetooth, Bluetooth Audio, USB, IPOD, Aux In

OEM Integration Piece: Audio Control LC2i (tapped the signal using the front inputs - before the bose amp)

Front Tweeter and Mid Amp: Rockford Fosgate T4004

Sub Amp: Rockford Fosgate T5002

Subs: 2 x 12" Kaption Audio SPL 1200

Enclosure: 2 cubic feet sealed

Mids: Hybrid Audio L6

Tweeters: DLS UR1

Crossovers for Mids and Tweets: Hertz Mille MLCX2 (bi-wiring for mids and tweets)

Power Wire: Stinger 2 gauge

Sound Deadening: Dynamat Extreme (trunk and trunk lid) - will do rear deck and doors later

Power wire and fuse holder:



Door off and Cascade Engineering Deflex Pad Mounted and Stinger 16 gauge wire for mid:



Factory 6 x 9:



Modified factory spacer:



Hybrid Audio L6 mounted:



Factory Bose Tweeter:



DLS UR1 Tweeter with plate:



Factory Tweeter Cover:



Audio Control LC2i Bass Controller:



Factory Nav/DVD Player:



Amplifiers mounted on a 1" mdf board. Barely fit with only about 1" to spare. This was taken before wires were cleaned up:



Will have to redo the subwoofer trim covers later:



After hours of tuning I'm finally happy with the sound. The mids get very loud, with very good clean midbass/midrange. The tweeters sound amazing in the factory location. I still have the factory center speaker installed and it really helps with the imaging. I have a really wide, high, centered sound stage. I hope you enjoyed the pics.

 

Clean install. Do you hear any rattle from the rear deck or trunk?

 

x2. I have rattle from the rear deck area that's getting annoying even after dynamat on the trunk lid and bottom rear deck. Wondering if anyone knows what areas to focus on?

 

I do have rattling in the rear deck. I haven't dynamatted that area yet, but will soon when I feel like it. I know most of the rattling is coming from the rear sun shade and the rear deck plastic panel.

 

I think I might have to remove the sun shade since dynamat doesn't seem to do any good

 

can you explain how you got the tweeter cover off. and dod you run new wires up there i was looking at it the other day and it looks really hard to work in the small space to get the wires up there

 

and how big is the hole for the top. 3inch?

 

I actually removed the rear speakers on the deck and dynomatted it because they weren't being used anyways. Even with the sun shade up or down, it got rid of the rattles.

 

To remove the tweeter cover, I used a right angle pick carefully and removed the black circle thingy (red arrow pointed to it). I then put my finger in the small hole and the tweeter cover came out easily.



The factory tweeter is 3.5", but it can easily fit a 4" with small modification with a dremel tool. I did run new wires for the tweeter. I used a 3 foot long wire tire and fished the wire down the hole. You can get those long wire ties from most hardware stores.

 

cool thanks. and your not changing the rear speakers on the back door?

 

Nice! Keep us updated

 

I'm keeping my speakers on the back door because I see no point in changing them since I have the fader turned mostly to the front.

 

That's how the sound should be. From in front of you. In my last car all I had was a set of 6.5" components and it sounded better than the Bose with 9 speakers.

 

Hey New here does anyone kno if 2 15" Kicker L7s would fit with these enclosure measurements...

 

whats gonna happen to the people in the back seat all theu gonna feel is the bass from the seat. im just saying i never heard a system with only the front has speakers

 

My box is 30" wide and 13.5" tall and there's only a few inches on either side to spare. Might be better off using a sealed box then the subs will only need 1.5 cubes each.
As long as it sounds good from the driver's seat I don't care I rarely drive with passengers anyway.

 

Your box with the dimensions of Height: 16-1/4" / Length: 38-1/4" / Depth: 16-3/4" is not going to fit.

 

shoot whats the biggest size box that would fit in the maxi?

 

your tape measure will have an answer

 

Sorry platinum300 not an official Maxima owner just yet...

 

max width is about 32" and a height of around 15"

 

Was the Audio Control LC2i unit easy to install? The reviews on it are great.

 

The Audio Control LC2i is super easy to install. It accepts a pair of speaker level inputs (left and right), tap into the front input (before the bose amp). The LC2i has a subwoofer preout and a full range preout. I highly recommend getting this piece if you have the Navigation Package.

 

Tapping into the front input before the amp is the best signal? I hear too many ways to get the proper signal for after market amps.i also hear you should grab it after the amp and dont use a Loc? They said to use rca ends on the output of the bose amp,which is using high level input that is going into the amps low level input.lastly,other say to use the rear output of amp to a loc to rca input on new amp.which is best for connecting to a aftermarket amp on the max with bose/nav?

 

What you want is to tap into a clean signal (full range signal), meaning a signal that hasn't been eq'd or x-over. That was the reason I tapped into the front input channels (before the bose amp).

If you were to grab it after the amp, then it wouldn't be a clean signal (full range). It maybe ok doing that way if you were only adding a subwoofer amp (tapping into the rear Bose subwoofers after the amp).

If you were to add amplifiers to power your mids, tweets, and subs, then definately tap into the front inputs (before the amp). I highly recommend you get the Audio Control LC2i for various reasons: easy to install, it's an active line output convertor, the preouts gives you a maximum of 9volts, it has Accubass. Accubass is a feature on the LC2i which compensates for lost bass at higher volumes. What happens with most factory amplified systems like Bose, Infinity, etc. is when you crank up the volume, the factory amplifier reduces the bass going to your speakers to protect them. This is very true with the Maxima's Bose system. MTX RE-Q is another LOC that has the same bass compensation technology, but it's a lot harder to install.

 

So which exact pairs of wires did you tap into for the signal?

 

I tapped into the front input wires (before the amp). I can't remember the wire colors. I'll take a peek later and let you know.

 

any suggestions on an aftermarket radio i could install on my sport package....i dont got the navi setup so it shouldnt be too difficult...let me kno

 

I recommend a double din unit from Alpine or Pioneer

 

Here are the front input wires as promised:

LF+: white/red
LF-: black/red

RF+: white/blue
RF-: gray/purple

 

Awesome setup!! I have an Altima and I'm gonna use your setup as a model for mine!!

 

do you know how to take the bose radio out?

 

Here's a Youtube that shows you how to remove the radio.

Where did you get the tweeter plates from? I miss the Highs with the Bose tweeter.

 

I made the tweeter plates. Very easy to make. Just use the factory tweeter as a template.

 

Where is the factory Bose subwoofers in this thing? Is it on the rear deck or on the doors? Are they all powered by that Bose amp or is it just the so called subs?

 

the "subwoofers" are just 2 6x9s in the rear deck.

 

Thank you for the reply. I was wondering if it would be a good idea to swap out all the speakers(Front door & rear door) with alpine type R. Would the stock amp have enough power to drive them all?? Or should I go with type S ones??

 

i think i read somewhere the stock speakers are 1 ohm. so replacing 1ohm speakers with 4 ohm speakers will leave the 4 ohm speakers with only 1/4th the power of the stocks.

 

So are they 1ohm speakers??I thought that they were 2ohm ones. I was thinking of getting infinitys coz there are some decent 2ohm ones that they make or the kenwood excelons.
