Brent P's 2007 Saab 9-3 SportCombi Wagon

Improving the sound while keeping the factory stereo

Brent P's 2007 Saab 9-3 SportCombi wagon

Just because you can't replace the radio doesn't mean you can't improve your car's audio. Brent P, who works in Crutchfield's IT department, boosted his 2007 Saab 9-3 wagon's sound and functionality without installing a new receiver. Here's how he did it:

So you can't replace the receiver. Now what?

"When I worked in sales at Crutchfield, I would often get calls from customers who really wanted to upgrade their car's audio system, starting with the receiver. Then they'd tell me about their car and, well, sometimes I'd have to be the one to deliver some bad news. Unfortunately, on some cars, radio replacement just isn’t possible because there's no dash kit and/or wiring harness available. 

Needless to say, some of these folks were quite disappointed. Sometimes I'd have a chance to tell them about all the things that ARE possible with their cars, but sometimes, they'd just hang up in (totally understandable) frustration. Trust me, I feel their pain, but the radio is just one element of a good system. There are plenty of ways to improve your car's sound while keeping the factory radio in place.

Mercedes-Benz, Volvo, Acura, Jaguar, Porsche, and Lexus are just a few brands that make it really challenging to install an aftermarket receiver.  Saab is another one – and as the proud owner of a 2007 Saab 9-3 wagon, I know exactly how owners of those other brands must feel. When you enter your car info into our Vehicle Selector or talk to one of our experts and find that, radio-wise, there's nothing to be done, it IS frustrating. But there are other ways to get the sound you want in the car you love."

Infinity dash speakers saab

These 3-1/2" Infinity speakers fit right into corners of the Saab's dash.

New speakers make a big difference

"As an example, here’s what I did with my car. I can’t replace the factory radio because we carry neither a dash kit nor a wiring harness (See note below - Ed.) that works with it. Once I accepted the fact that the touchscreen nav receiver of my dreams was just that – a dream – I focused on improving the things that I could improve: the factory speakers.

I chose 2-ohm Infinity speakers because they worked best with the factory radio. The front doors got a set of 6-1/2” Infinity Reference coaxial speakers in the front doors, installed within 6.5” Boom Mat speaker baffles to quiet the door rattles.

I also installed a set of 300 Hz Bass Blockers to give the mids more 'room' and let the factory subwoofer handle the bass.I didn’t replace the factory 10” Pioneer subwoofer or the two factory amps this time around, because they're doing the job I need them to do for now. Maybe later, though.

I installed one set of 3-1/2” Infinity Reference coaxial speakers in the dash corners and another set in the rear hatch. I also replaced the factory center dash speaker with a 4" Sound Ordnance P40 speaker. Now that the weather's turned cold, I'll be installing baffles on these speakers, too. The rattles and vibrations tend to increase when the temperature drops."

Pro Fit bracket in a Saab 9-3 wagon

The Pro.Fit bracket keeps Brent's iPod accessible and secure.

Portable tech solutions help, too

"Okay, so that touchscreen receiver is never going to happen with this car. That's a bummer, but I'm still able to enjoy a lot of the same functionality.

I put a Pro.Fit bracket on the dash to hold my iPhone®, which plays through the factory radio with help from a Scosche auxilliary cable. As for navigation, I hook up a portable GPS for long trips out of town, and that works just fine.

My Saab doesn't sport the most elegant, high-tech dashboard in the company parking lot, but my music sounds terrific coming from the Infinity speakers, and that's the important part. I'm still looking at the same old factory receiver, but it's performing better than ever before."

Wondering what fits your car? To find out, visit Crutchfield's Outfit My Car page and enter your vehicle information.

Note: While there are kits and harnesses available elsewhere for this car, none of them retain the Saab's factory warning chimes. So while it's possible to swap in a new receiver, we don't recommend it because of the lack of chimes and the fact that the installer still has to run an accessory power wire to the fuse box. When in doubt, we always err on the side of safety.

    I have exact same factory setup and the other day my 10" sub just all of a sudden started putting out continuous bass even without music going. Just quite loud annoying bass. I unplugged that connector which stored the bass. I took out the entire enclosure, disassembled it and put a brand new Pioneer sub in it. I put it all back together and threw it back in the car. Same result. Does that mean the amp is fried? I would think that if an amp goes the bass would just go dead. Any help would be appreciated.

    Hi Brent (or anyone else with more knowledge on this than myself), I have the same car model and have not had a working subwoofer since owning the vehicle. I removed and tested sub and it works so the sub amplifier seems to be the problem. Is it possible to just simply replace this amp with an aftermarket one? I was told by a Saab mechanic that it must be the same factory amp and can't be from one previously installed in another Saab. I don't know much about this or the reasoning so any help would be great. I may replace head unit as well with double din kit if that changes anything. Thank you!

    Trevor, Not sure about the dealer's amp story, but we'll see what we can do to help. I've sent your question to our sales team, and they'll be contacting you via email soon. For immediate help, you can contact them via phone or chat.

    So just to follow up Jon Paulette. You dont lose any factory chimes. Those are all done through the Instrument cluster, since Saab relocated the SID inside of there. You can run accessory power to the lighter, directly below the headunit. I have probably installed about 20+ headunits in various 2007+ 9-3s. To reiterate, you lose no factory warning chimes.

    I also have a Saab 9-3 of 2007 and I have replaced the reciever with a Pioneer, everything is available and very important, all sounds work, those of the blinkers, error messages, belt warning.Pre 2007 models are really a complete intervention, but from 2007 it is just perfect to do.

    Hi Jon, Do you have any updates to the door and front dash corner speaker recommendations? Neither is still available form Crutchfield. Also to be clear, the doors are 2ohm and the dash corner speakers are 4 ohm? Thanks, Rob

    Anthony, Good points, all. While there are kits and harnesses available, none of them retain the Saab's factory warning chimes. So yes, it's possible to swap in a new receiver, but we don't recommend it because of the lack of chimes and the fact that the installer still has to run an accessory power wire to the fuse box. When in doubt, we always err on the side of safety.
    I've updated the article to clarify this point, so thanks for bringing it up!

    "Okay, so that touchscreen receiver is never going to happen with this car. That's a bummer, but I'm still able to enjoy a lot of the same functionality." WHAT?! UNTRUE im sure you know by now that , there are many wiring harnesses and dash kits for the 07+ saab 9-3 right? many many people have aftermarket double din touch screens in these with no issues and easy wiring ...
