1980 Porsche 928

Use our shopping filters to find the right 2/3/4-channel amp to power upgraded speakers properly.

Amps for Adding Speakers for 1980 Porsche 928

Some vehicles require an amp bypass module, a line-output converter like the NVX XLCA2 or AudioControl LC2i, or a DSP to integrate with your factory radio and avoid bass roll-off. Bass roll-off occurs when a factory radio's crossover is designed only for the original equipment speakers, resulting in a not complete signal being sent to your new aftermarket amp.
