240z Sound System Upgrade

Post by Mark


When I originally purchase my Datsun 240z, it had an old cassette player and just two crappy speakers in the rear, one of which didn’t work. I was happy with the cassette player since I still had some tapes but because one of the speakers wasn’t working, I went and bought a pair of cheap ones. A week or two after that my cassette player stop working, and I think the speakers I got had something to do with that. I tried finding another cassette player on eBay but either they weren’t old enough (to match the car’s era) or they were just ridiculously overpriced. So I decided to just do a complete overhaul of the sound system since I was spending so much time driving the car anyway.

I had two objectives, the first was that whatever I decided to do, it shouldn’t mess with the look of the car. The second objective was that I didn’t want to spend an exuberant amount since I already did that with my FJ. So I limited my budget but still tried to get a decent sound. So after a bit of research I went with the following:

Pioneer MVHX560BT Digital Media Receiver KD30
240z Front Speaker Panels (the 240z only had speakers in rear) KD28
Rockford P1650 6.5-Inch 2-Way Full Range Speaker KD16
Rockford Fosgate Punch P152 5-Inch Full Range Coaxial Speakers KD17
Alpine KTP-445U 4-channel Power Pack Amplifier KD35
Kenwood KSC-SW11 Compact Powered Enclosed Subwoofer KD42


The Pioneer head unit was perfect since it wasn’t very expensive, had bluetooth and was around half the size of regular units which meant I could hide it in my glove box. That way I could keep the old cassette player visible keeping with the car’s era, but behind the scenes I would have a much newer system running the show. Now when I turn the car on, the head unit automatically connects to my phone via bluetooth and I then can control the music and volume all from my phone without ever needing to open my glove box.


For the speakers I went with Rockford Fosgate because they were affordable and had gotten a lot of praise, plus there was a bit of nostalgia involved since I installed Rockford Fosgate components in my car back in university. For the amp I went with the Alpine model because it was small enough to hide under and behind the dashboard while still being powerful enough to run the speakers. Finally I got a tiny Kenwood subwoofer that fit perfectly behind the passenger seat and away from sight.


The result? The music sounds so much better now obviously but the interior still looks the same so you can’t really tell there is a powerful sound system in the car. I didn’t install the stuff myself, instead I went to my favorite car audio guys Zaharat Al Naseem. It took maybe an hour for the whole install and they did a great job of hiding all the wiring.


For those of you interested I’m starting a build page for my 240z where I will document everything I’ve done and will be doing to it. You can access that [Here]. Also again for those interested, I have a build page for my FJ, its around 4 pages long and I’ve been updating it since 2010, you can find that [Here]

    Speaking of interiors, do all the gauges work? and did you convert the bulbs to LEDs? They would look really good at night.

    Hey Mark, don’t know if you know this but you could get a membership at the Kuwait Car Museum and get some free services done to your car. You should pass by whenever you’re free. Let me know if you plan on going anytime soon.
