Okay, I know I'm going to be slammed, but here I go anyway......

I soldered a $9 speaker level to line level converter to the Bose Head Units rear speaker outputs. I ran 2 RCA ended patch cables to a Rockford Fosgate P3001 mono amp that I located in the glove box.

I installed (2) 10" Sony subs in a sealed box and put it in the trunk facing the rear.

The end result sounds excellent to me.....all the way up to 31 (full volume. Metallica just could not sound better. It slams! And the Bose highs everywhere else are very clear.

Now the box is awkward to say the least. It was more of a test to see what it all would sound like. Although I couldn't expect it to sound any better, I am interested in having some usable trunk space, so I am building a box that will slide in under the Z bar. If it does not sound as good, I will not use it.

I can use the fader to adjust front to rear, but I have found that it is a perfect balance at "0".

Perhaps I'm not the audiophile that most of you are, but for less than $450, I think it turned out fine.

 

Nice. I'm thinking of keeping my BOSE system for couple more months, might do something like that too...thanx for the info...

 

Yea we did the same thing to a buddies lincoln ls. If you just want some more bass this is a good option as it costs alot less than gutting the entire system but like you said as far as audiophiles are concerned this setup is unacceptable the increased bass can easily overpower the whimpy bose componets ...for me the bose has got to go!!!!

 

Lets do a quick test. Did the original BOSE

A. Sound pretty good to you stock.

B. Sound kinka bad, or

C. Did it make you want to puke blood.

Just curious.

 

Truth be told....I was very disappointed with the Bose. I can't understand why Nissan would put such an awkward system in a car that is clearly designed to be easy to work on and easy to modify. For example: Speaker level outputs to amplifyers located all over the car??? and automatic volume compensation on the bass only ??

Yes, adding the amp and sub-box cleans up the low end problem, but leaves the mid's and high's exactly where they were - not exactly audiophile quality.

I do believe some folks would not mind and might prefer taking this approach. It keeps the stock Bose unit in the dash and provides an incremental increase in sound quality.

My experience with expensive audio upgrades is that they don't always help the resale value. I might decide to sell the car someday, so maintaining a factory look will always be a consideration.
