    Sent you a PM, thought I would take a shot here too. Even trade for this?

    Cant trade for subs unless you have an audiomobile evo or new alpine type r shallow t line.

    I have a stealthbox and need a sub 10" that takes power and is less than 5.25" deep. My IDQ v2 10 cant keep up at high volume.

    Oh I forgot treo made amps. No thanks, I like the DLS amp more as far as a trade. I would trade for a nice and powerful 3/5 channel but dont need speakers.

    I do need a zapco dc ref 200.2

    General info :

    Size: 21"W x 3-5/16"H x 12"D

    Single-ended push/pull design for stability at 1 and 0.5 ohm

    Discrete differential inputs for reduced noise

    Dual power supplies

    The C and D channels can be set for Hi-Current or Hi-Voltage operation; the A and B channels are permanently set to Hi-Voltage operation (the A and B channels cannot be switched to Hi-Current operation).

    The Hi-Current and Hi-Voltage modes differ as follows:

    Hi-Current Mode allows you to connect a speaker or combination of speakers with an impedance as low as 0.5 ohm for a stereo load, or 1 ohm for a bridged load, to the C and D channels.

    Hi-Voltage Mode allows you to connect a speaker or combination of speakers with an impedance of 2 to 8 ohms (4 ohms bridged) and provides better sound quality; the Hi-Voltage mode can be used for all four channels.

    Pulse power supply regulates fluctuating voltage from a vehicle's battery while being light weight and highly efficient

    Direct switch allows for best possible sound

    Negative Feed Back circuit can be turned off for clearer sound

    Independent voltage amplifier power supply

    MOSFET Power Supply

    Protection circuits:

    Thermal protection
    DC current
    Speaker terminal short circuit

    Indicators on top of unit:

    Mode indicator: One of two LEDs illuminate to show if the amp is in High-Current or Hi-Voltage mode

    Power/Protection indicators:

    Over Current LED illuminates in green during normal operation, switches to amber during an over-current situation
    Offset LED illuminates in green during normal operation, switches to amber when voltage going out is too high
    Thermal LED illuminates in green during normal operation, switches to amber when the temperature rises to an unsafe level

    Best frequency response: 5Hz - 100 kHz (+0/-3dB)

    Inputs, Outputs, & Controls

    Inputs, Outputs and Controls (all located on front of unit under removal terminal cover):

    Gold plated stereo RCA inputs for front and rear channels.

    Ground and +12v inputs: Gold plated terminal strip, note that there are two of each of these.

    Remote input: Spring clip, accepts wire with AWG 22-16.

    Hi-Current/Hi-Voltage switch: Allows you to select operating mode for the C and D channels.

    Test Tone recessed button: When pressed puts out a test tone that indicates that the unit is operating properly.

    Speaker outputs: For A, B, C and D speakers, two gold plated terminal strips. Bridged mode uses the L+ and R- terminal outputs.

    Low Boost level knobs: Two knobs, one for the A/B channels, the other for the C/D channels. Allows you to boost bass by 0 to +10dB (centered at 40Hz).

    Level Controls: Two knobs, one for channels AB the other for channels CD. Used to set input level

    Direct Switches: Two switches, one for channels AB the other for channels CD. Can turn on or off. In the ON position the input signal does not go through the crossover or bass boost circuitry, which results in a cleaner signal for better sound quality.


    Frequency Adjustment controls: Two controls, one for channels AB the other for channels CD, can be varied from 50Hz to 400Hz.
    X10 Switches: Two switches, one for channels AB the other for channels CD, used to change crossover frequencies from 50-400Hz to 500Hz to 4kHz

    Filter switches: Two crossover switches. Allows you to select low pass, high pass or off for the front and rear channels.

    NFB switch: Negative Feed Back switch. Can select on and off, when on negative feed back is applied which reduces certain types of amplifier distortion but which some people claim muddies the sound. Note that usually all amplifiers except high end amplifiers use negative feed back. This switch effects A,B, C and D channels.

    I like the dual mono and always wanted to try the DLS A series so trade is pending with go go thrash.

    This is no longer available.
