Stereo Speaker Amplifier Repair - NSX, 1991-05

Check out our blog post explaining the issue, here.

A common problem with older NSXes is the stereo amplifiers failing. Typical symptoms include no audio from the speakers, popping, or squealing. We replace the defective circuitry with new upgraded components and test and verify each function on a test bench that replicates the factory stereo system.

We offer the repair via:

• customer supplied amplifier: send us your amplifier (or amplifiers) as shown in the photo. We will inspect, repair, test, and return your unit back within about 2-3 weeks of receipt. 

Special note:

• In some cases, the stereo amplifier may be severely damaged beyond repair. In this case, We will let you know. If a core is available in house, we may offer to sell the unit to you. Check out our blog post explaining the issue.
• Each unit is tested completely before shipping using a test bench ensuring that the stereo amplifier is working properly after repair. Please note that similar symptoms can also occur from other parts in the vehicle failing, including the stereo head unit.
• Other companies use non-NSX stereo amplifiers. Inspect your amplifiers to see if they have NSX part numbers.  The NSX part numbers are 2205/2305/2405 for the door amp, and 2206/2306/2406 on the subwoofer amp.  This can be found printed in the white square on the board itself.
