Was the sound level from these speakers still near stock? I know the stock speakers and amp were rated at a really low wattage (like 32) and am concerned about having very quiet speakers due to not having the amp to power them to full potential. I know very little about audio so apologies if my theory is totally off but just want something that'll work so I don't have to think about it.I recently installed a set of Harmony speakers in my 1993 VR4 with OEM head unit, all stock radio wiring, etc., and am happy with the results.
Door: Harmony HA-R65
Rear: Harmony HA-R69
Wiring adapters: HA-729301
A complete package with all speakers and wiring adapters is available on Amazon for $105.95 as of now. This is marketed as a OEM-compatible replacement for improved sound with OEM radio: Amazon.com: Compatible with Mitsubishi 3000GT 1991-1999 OEM Speaker Replacement Harmony R65 R69 Package: Car Electronics
The rear speakers are a direct fit replacement.
The door speakers require drilling 4 new holes in the stock plastic speaker mounting plate to line up with the mounting holes on new speakers.
The wiring adapters are a bit janky and don't fully clip/lock with the factory connector, but it plugs together and makes sufficient contact.
I can post some pictures later.
For the dashboard speakers, I've ordered brand new OEM speakers through my dealer because there is no direct fit aftermarket optional available, and I don't really want to deal with fabricating adapter plates and creating an obviously non-OEM look. They had to be ordered from Japan, so they are taking quite a while to arrive. Ninja Performance also stocks them: Mitsubishi OEM Dash Speaker MR207971 (MR207971) - Ninja Performance - Affordable Performance Auto
OEM part number for dashboard speakers is MR207971 or MB771611. I believe MR207971 is the newer part number (supercedes MB771611), but both are compatible.
DISCLAIMER: The info in this post is known to be relevant to 3000GTs with NON-Infinity sound systems! I know for sure that the OEM dashboard speakers I referenced do not work with OEM Infinity sound systems. I don't know if the Harmony speakers I reference are a good match for Infinity systems.
Not really. I would expect physical dimensions to be identical across all years of the 3000GT/Stealth. IIRC, there are differences in speaker impedance for some of the speakers in the Infinity systems vs non-Infinity systems. I'm curious to know why an installer said the Harmony HA-65 wouldn't work on the doors. Harmony claims it fits all years.Are you familiar with differences between '93 vs. '94 VR-4 speakers?
Everything went back together (both front and rear) without modification (except new mounting holes for fronts), and without any noticeable contact between the speakers and the interior panels or speaker covers.Do you have any issues with the new speakers causing the speaker panel to protrude?
They matched Ninja Performance's price for me (~$70 each). It was convenient because I was also ordering another part that I could only get through the dealer via special order (brand new power seat lumbar/bolster switch!).How much did the dealer charge for MR207971?
Are you using non-resistor plugs? That's usually the reason, or you have a wiring issue giving feedback.I wouldnt mind upgrading my speakers but the whirring noise drowns em out, how do you get rid of hearing the engine through the stereo? Makes me not want to even bother with speakers.
