After days of narrowing down options I finally decided on an Audioque AQ120.4 imported from the great city of OKC.
The AQ120.4 is the most versatile amplifier in our lineup. With its feature rich design you're able to power a complete system, including the mid/highs and the sub off one amp. It features a high power 4 channel class A/B output section that delivers superb sound quality and ample power to drive multiple arrays of speakers. The 120.4 features variable high and low pass filters that can also be used in a band pass configuration. The 120.4 also has variable bass boost, remote gain control w/ clipping indicator, and RCA pass through jacks to optimize the amplifier for multiple types of installs.
DESIGN FEATURES
Stable down to 2ohm Stereo or 4ohm Mono
Stereo Audio Outputs for Daisy Chaining multiple amplifiers
Four way protection circuits: Speaker shorts, DC offset, High/Low voltage, Thermal protection
Double sided boards with high current MOSFET switching devices
24db/oct slope crossovers, Fully adjustable High Pass, Low Pass Filter and Band Pass Filters
Includes Remote Gain Knob (for use in BP/LP mode on channels 3/4)
Specifications
Model AQ120.4
Dimensions 15.75" x 9"
