JBL Premium Audio System uncovered

Is there a chance that someone will offere a pin for pin replacement for the JBL/Prius amplifier?

According to naterprius earlier in this thread, the Land Cruiser uses an analog amp that may be just that - it'd be nice to know for sure. Expensive new, but some LC's have surely been wrecked by now ...

And there is a chance that it may not generate the "beeps"!

 

Hi Danman, that is some good news!

I have seen the $200 ipod2car adaptor, but I think I'll be satisfied with just the audio input.
Hmm just thought of something else..: will this disable the bluetooth carkit phone audio?

 

Nope. Nav intercepts the driver door speaker from the amp, and powers the speaker itself.

 

Thanks DanMan32 ,
That's great. Seems like my worries are (almost) over. Just have to get my hands on a male-female set of the connector they are using. Any chance of this being a standard connector? Is it used in other applications as well?

 

Just started a JBL beep related thread at http://priuschat.com/forums/-vp77985.html#77985

It has a photo of the inside of the amp for those who are interested.

 

I have the JBL 9 speaker system and I was thinking about simply upgrading the tweeters in the front doors (any recommendations) and then adding a powered subwoofer into the compartment in the back.

Anyone tried something like this? Does anyone know where to hook the powered subwoofer? Should I get the output directly from the amplifier (under the seat) output? Would the sound get through the rear storage compartment OK?

I think that more efficient tweeters in front would help alot since the sound does get better at higher volumes.

Are the speakers that are in the Prius JBL system premium speakers? How much does it help to replace the main speakers in the front?

If I purchase replacement component speakers for the system, do I just forget about using the supplied crossover? I would think that the crossovers are designed for the tweeter and the woofer and by not using the crossover, it could cause worse sound.

my prius arrived last week, love it!
I am wondering how my JBL amp in- and outputs correspond to the schematics posted previously in this thread. Here is a picture of the amp connectors. It seems to me that the small black 2*4 connector is the audio from the head unit. Instead of black and white wires, I see one black/white striped wire. Does anyone know the purpose of all these different connectors? See picture attached
I see 5 (L to R): One blue connector (unused), one grey, one black, a small white one and a large white one. From the wire diameter of the large connector I assume this is the speaker output and power input.

 

Geronimo,
In the 2005 US model, the nav unit is made by Denso and sits underneath the drivers's seat. This photo shows the great similarity with yours: http://priuschat.com/forums/download.php?id=394 I was under the impression that Toyota only used Aisin Nav units in Japan. Is yours a Japan market car? The Aisin model supports the backup camera and auto-parking option offerred only in Japan. Here's the discussion which originally linked to the photo: http://priuschat.com/forums/-vp18127.html#18127.

The JBL amplifier/equalizer (for those who have it) is under the passenger seat in the 2005 US mode.

 

How about this idea?

Since I don't care too much about the sound in the back of the car...
Switch the outputs of the amplifier (rear outputs go to the front speakers and front outputs go to the rear speakers). Replace the front speaker with a component setup and passive crossover. The amplifier should put out plenty of power and the new speakers would make a huge difference in the front seat sound. The back speakers can take the worse sound. The the speakers from the front and put them in the back since they are supposedly higher quality. Maybe add a subwoofer if needed. With this method you don't have to replace the amplifier and you can get clean, unfiltered sound to the tweeters in front. The dsp internal to the amp would now drive the rear tweeters.

Any thoughts?

 

Phew! Good thing that I didn't start soldering right away! Thaks Synergyguy and Brosnan! The unit picture you point to is the same as far as I can tell. My unit has a different label (Toyota sticker) though. As I live in Europe, the car may be different from the US models. We have only two varieties of prius: a standard one and a Business edition with added nav, JBL 9 spkr, smart key and bluetooth.
Meanwhile I have located the amp below the passenger seat. It is somewhat harder to reach, this weekend I'll take it out to see the connections.

This Japanese video option seems interesting..would this be plug and play or serious hacking?

 

Why not start out with something very easy to do?
Install, or as I did, pay a pro to install a sub with amp.
Disconnect center speaker. (dash in JBL).
This is all I did and I am now very pleased with sound of cd's.

 

Has anyone heard yet of a manufactured Prius sub box other than the Bazooka. So far all I have been able to find is someone willing to build be a one off box for an excessive amount of money.

 

$150 is not excessive for a sub box that fits the Prius perfectly. I think it's well worth the money.

The average quote I am getting locally is closer to $500 to fabricate a fiberglas enclosure that will fit in the rear passanger side trunk recess (This is without speaker). This is my desired location.

I wish to use a JL speaker or equivilant in my update. While the Bazooka is a good product and produces low end, it is not the type of low end I want for this installation.

 

I had a custom box made out of MDF for $200, not including the speaker. Very good sound quality - better than my previous factory enclosures.
