8-Channel Amplifier and Speaker Bundle

This bundle pairs an Alpine PXE-C80-88 OPTIM8 8-channel digital sound processor amplifier with two R2-S65 6.5-inch coaxial speakers. It is built for car-audio enthusiasts who want high-resolution playback and integrated amplification in a single package. The system targets drivers seeking detailed sound tuning without assembling separate components.

Automatic Tuning and High-Resolution Playback

The amplifier includes automatic sound tuning via a PC or iPhone app for precise measurements, plus a 31-band EQ for manual adjustments. Hi-Res audio playback and wide bandwidth support extend the frequency range for clearer reproduction. The bundled speakers add glass-fibre reinforced cones and integrated tweeters to handle the processor's output with reduced distortion.

Power Distribution and Frequency Limits

The internal amplifier delivers 50 watts across six channels at four ohms plus 15 watts for the remaining two channels, which restricts total system headroom for larger installations. Speaker frequency response reaches 40kHz, but the amplifier's processing bandwidth and power reserves set the practical ceiling for dynamic range. Buyers needing more output channels or higher per-channel wattage will find this platform limiting.

Questions about this item

Will the 31-band EQ need recalibration after the break-in period?

The 31-band EQ stores its profile in the processor; recalibration is only needed if speaker placement or listening preferences change.

At what output level does the 50W x 6 amplifier section reach its thermal limit?

The built-in 8-channel amplifier is rated for continuous 50W x 6 at 4 ohms; sustained peaks above this level trigger protection.

How much heat does the 15W subwoofer channel add during all-day playback?

The 15W channel runs cooler than the main six channels; total chassis temperature stays within spec for extended use.
