Garage Audio Recommendation

The TKO-8.1K is not an entry-level amplifier. To achieve its full potential, we recommend pairing it with a professionally designed electrical system including high-output alternators, upgraded batteries, heavy-duty cabling and a custom enclosure built specifically for your chosen subwoofers. When matched correctly, this amplifier is capable of delivering competition-level bass performance that few amplifiers in its class can match.

For customers chasing maximum output without compromise, the Zeroflex TKO-8.1K is one of the most powerful amplifiers available.
