Calibra "Stealth" 4-channel 4x100W car audio power amplifier

Calibra "Stealth" series 4-channel 4x100W Tri-mode power amplifier

Main features and benefits
* Amplifier is fully imported, made in the USA - a great quality product
* 4 completely separate amplifier channels, in 2 groups of 2 channels each, both groups bridgeable
* Each channel can drive 2 separate speakers(L & R), or one speaker at double power (bridge mode), or 3 speakers (tri-mode)
* The combination means you can easily drive 2, 3, 4 or even 5 speaks - versatile!
* Integrated high-pass (>80Hz) and low-pass (<120Hz) filters on both groups - use with mid/tweeters, subs or full-range speakers
* Drives output impedances of 8 Ohms, 4 Ohms or 2 Ohms - gives versatility
* 2-Ohm stable - get maximum power out of low-impedance speakers with ease
* Low THD and high Signal-to-Noise ratio - great performance and high fidelity
* Can accept low-level inputs from your pre-amp, or high-level speaker signals
* Gold-plated RCA connectors for pre-amp inputs, Molex connectors for speaker inputs
* Remote power on/off terminal - switches the amp on and off together with your head unit
* Attractive, anodized, extruded aluminium case (purple)

My comments
* Amplifier is approx 5 years old, but is in the box and has never been used
* Supplied with speaker connectors, pre-insulated lugs (for power) and 2 spare fuses
* Complete with instruction manual and original packaging
* Reason for selling - I never got around to installing it!
