The one thing that’s been haunting my wife and myself has been the music system. We just couldn’t come to terms with the stock system and wanted to get it changed asap. So in spite of the quiet period that we’re observing for the car, we decided that today was a good opportunity to visit Autoshop and get the surgery done since we’re going to be out for the next two weekends.
I had the following things already carried over from the Safari with me:
- Blaupunkt GTA475 4-channel amplifier
- JBL 3501 Mono Amp
- Infinity Kappa Components 62.7i (front doors)
- Infinity Kappa 2-way speakers 62.9i (rear doors)
As usual we started with the option of adding the amplifiers to the stock system to save on money. Now, the stock system was definitely not the best, but it did have all the basic things you need and we wanted to see if there’s any way amplifiers could make it sound better. A Scosche hi-lo converter could be added to the stock setup to and transfer speaker outputs to the 4-ch amplifier. While this was the cheapest option, we could possibly use only one 4-channel amp and not the mono amp. This would also mean bridging of two channels to feed the subwoofer and hence we’d also lose the independent controls for the front, rear and sub. I’ve used a bridged channel setup once before with a Pioneer HU which had built in pre-outs and was never really happy with it. The improvement in sound quality in the Safari with two separate amps was tremendous. There was no point in going back in time and learning the same lessons!
I had already done some homework on which system to install if needed. It had to be the 8590BT with all the latest features including AppRadio and three 4V pre-outs. The only cruel thing about this HU is the cost, at about 29k you couldn’t really say it was affordable. But then once the AppRadio features are enabled, I guess it will pay you back on savings for navigation modules etc. With that in mind, we decided to go with it and not really settle in for any other brand or model. Also, even though this one is a DVD touch screen, it did look like it was more focused on delivering high quality audio performance which is what I needed. Honestly, the DVD playback is rarely going to be used, unless we get some headrest monitors etc which isn’t happening anytime soon.

Anyways, coming back to the story.
- The 8590BT was chosen to replace the stock system.
- A steering interface was to be installed to revive the volume and track change controls on the steering wheel. We’d lose functionality on the call connect/disconnect buttons though. I wasn't going to do this initially but this was a demand by the missus and there was no override available
- There wasn’t enough place for a 12” sub enclosure once the last row seats were reclined for comfortable seating. So the decision was to install a 10” sealed box GroundZero subwoofer which came in highly recommended by Kumar from Autoshop.
- The compos were taken care of already and so were the two amplifiers
- Wiring was going to be GroundZero which looked pretty okay to me at least
- The 4 doors were going to get some serious damping
- The Pioneer HU had an input for rear camera but the stock camera had some other type of connection and needed another converter to work with the HU. So one more item got added to the list.
- The system needed to be fitted with an adapter to eliminate any panel gaps on the dash, this was nothing but a small plastic insert that fills the gap. Having it doesn't make the system look amazing, but it's absence would have made the install look a bit ugly for sure.
With all of this finalized, work began at about 12PM and it was estimated to go on till 6PM.
The door panels were stripped down…
Front seats were removed…
Dashboard panels were opened up …
Stock system was removed – second picture shows the rear connections whereas the first picture shows the model number information.
Steering control adapter was added…
The 100gm plastic speakers were taken out….
And yes, you read it right! The stock speakers are nothing but a joke. With an all plastic construction, they weigh not more than 100g each with a puny 20W rated output. Not sure what Toyota was thinking when they chose to install these in a 30L car.
While they were busy with the ICE installation, I also noticed the scooter horns provided as stock. Asked them to change them to Hella Red Grills which do duty on my Thar as well. I didn’t want the wind tone horns even though they sound really nice, reason being, they’re prone to water damage. I’ve already broken on set on the Thar and didn’t want to go that way ever.
End of the day, it was the moment of truth and the bill was enough to make us decide that today’s dinner will be a quiet family affair at home instead of the usual dinner options.
Quick Review:
- The 8590BT is loaded with features, some are functional and some cosmetic, but nothing is useless for sure
- The door damping has made a big effect on the lower frequency notes. The Infinity Kappas sound so much better even without the sub-woofer. This was never the case in the Safari where they served me for the past 3 years. In the Safari, the moment the subwoofer was turned off, a good part of the sound spectrum was noticeably lost whereas now it's much richer.
- The GroundZero subwoofer sounds quite good, it still has to be broken in but even now it’s quite powerful for the size.
- The sound stage is no longer front heavy – this was a common complaint with the Safari. I tested the sound in the middle row seat and it felt fairly balanced. The last row is definitely a big deprived because there are no speaker beyond the rear doors. The subwoofer is what fills the sound at the rearmost seat, not sure if there’s a way to put some more speakers at the back.
- Overall, my wife and I, both were happy with the output and concurred that this was definitely a “worth it” upgrade
- The green theme matches pretty neatly into the other green elements on the dash.
For now, the beast goes into slumber again until Saturday and we can get some of our favorite tracks compiled on an USB drive to listen through the 3000kms that it will cover in the next 10 days.
Unfortunately I forgot to click pictures of the finished setup, will have them up pretty soon.
