Infiniti J30 1993 Audio system

[adebuss]

The audio system on my infiniti J30 is working, But the display Screen doesn't work ; so you can't see the radio station or CD tracts that is playing on the system. What is the cause of this problem and how can I correct it. If I need to remove the audio system to fix it, What is the fastest way to remove it.

Look at http://www.carstereohelp.com for help in removal, and the FSM.

Never heard of a Clarion display failing, but I am sure it happens.

These Nissan/Bose head units are pretty easy to take apart. Once you have the head unit out and the metal panels removed, I believe there's a wire connector that plugs into the LCD. Maybe it just needs reseating.

Otherwise, it makes more sense to dump the entire system and start from scratch with aftermarket components.

Sigh!!!!

The correct response to your problem is that this is a common problem on J30s. The HU's often go out, sometimes the displays go out, sometimes the CD player stops working... I have personally discussed this with the owner of carstereohelp.com. The early Nissan/clarion In-Dash CD players werent very good. The best course of action, if the rest of your system is good, is to get another bose head unit from a Nissan/Infiniti and the harness adapter. Im running a CD player from a 99 G20 in my Q45 nad it works great... Maxima, pathfinder, etc head units will all work, if they are after 1996 they will need an adapter (which costs like $10 from Joe)

ANy of the square double DIN HU will fit. I would personally get a later one because they are more reliable.

You -could- spend $50-$100 on another OEM head unit, or spend $120 on an aftermarket stereo and gain two auxilary inputs, a more detailed equalizer, and the option to attach an iPod or numerous other devices with head unit controls.

Unless you're just into the stock look.

Anytime a Bose system fails, its an opportunity to move up to something decent.

UNfortunately, its going to cost more than that to properly hook up an aftermarket HU to the bose.

$120 for a new decent HU and 4 decent speakers? For a decent HU you'll be looking at 50-60, and then you have to install new speakers..

If the amps and speakers work fine, I would probably keep the bose. The 90-93 Q45 bose sucks, but from what I hear (no pun intended) the J30 bose is pretty good, same with the 94-96 Q Bose.

Getting a new HU for $75 solves the problem and you can do it really easily (an hour to install).. If you're happy with the sound quality of the bose I see no reason to spend money on a new HU and new speakers. For me why Im not going to change the bose unless it goes out...

An aftermarket will connect directly to the Bose amps (I've done it without any issues in my brother's G20). There are no issues with equalization, compatibility, or anything else. In fact, there's a dramatic improvement in audio quality right off the bat.

The Alpine system installed in my Q used the Bose amps for about a year until the amps started squealing. The last owner then decided to pay for a complete rewire.

Once the amps die, you can begin replacing speakers. You do NOT have to install new amps, run new wires, or buy new speakers right off the bat, but you should anyway since you'll be doing it once the remaining Bose bits go south.

$120 buys you a LOT of head unit now. The installation process requires a $10 wiring harness adapter, normal for any aftermarket stereo installation and available at any Wal-Mart, a $2 pack of wire connectors from Radio Shack, and 15-20 minutes of your time to connect the aftermarket harness to the vehicle-specific adapter. Diagrams are included and wires are all color coded so you can't screw up.

You can also pay a local shop $20-$30 to do the wiring if you provide the harness adapter, leaving you with the simple task of plugging the radio in and putting the dash together.

Here's my Crutchfield review:http://www.crutchfield.com/S-J...0#Tab

Its a matter of spending $50-$70 for the same old crap or $120 for something new. No rewiring, no crossovers, no new amps, no shenanigans, just a simple choice.

Oh yeah, I left out $10-$20 for a storage pocket to fill the new gap in the double-din slot, unless of course you buy a double-din head unit.

[elwesso]

From my experience, it depends on the HU how well it will hook up to the bose. I got a double DIN JVC unit and the volume was quiet. However, the sound quality wasnt bad at all, however if I wanted the volume to be decent I need to install line drivers in series. not a HUGE deal.

Still, it is a simple choice, but installing an aftermarket HU is definitely harder than R/R a factory HU.

I really am having a hard time justifying putting an aftermarket HU if your going to keep the bose. You might as well just get a bose HU, plug it in and be done with it. If your going to put in an aftermarket HU you might as well put in 4 new speakers and be done with it...

Its not a question of if, but rather when the Bose amps will fail and not if, but when the crummy paper cones will break. At least with an aftermarket head unit early on, you'll be one step ahead with a lot more features.

In the instances I've connected aftermarket decks to Bose-amplified speakers, I've tried Dual, Pioneer, Kenwood, and Alpine with fantastic results. I always pass on JVC car audio (at least their entry level stuff under $150) for build quality, exterior design, and user interface reasons. Arguably, Namsung/Dual has questionable build quality too, but the audio output is reasonably clean and powerful.

Right now, my brother's 95 G20 is using Pioneer 4x6 in the front, Sony Xplod 6x9 in the rear, Bose amps, and a $350 Alpine CD/MP3 head unit. With or without the amps, the sound quality is outstanding, but obviously its louder with the Bose amp connected. As lose as the Bose amp continues to work, they'll help in taking a little load off the head unit.

Nice thing on the G20 (and Y33 Qs) is that the factory amp is one single easy to replace unit under the rear deck instead of four separate ones mounted on the back of each speaker, making a removal of the Bose system a less urgent matter.

Ok so have you actually installed aftermarket (2 or 4 ohm?) speakers to the bose amps? I have considered doing this but just havent done it yet... if you're saying you had good results by putting an aftermarket speaker with OEM bose amps I may try that... I may use some new 6x9s in the rear.

I think were discussing 2 different things... some sort of miscommunication???

Just typical aftermarket 4-ohm speakers connected to Bose amps.
