The MS1000 is a limited edition amplifier made up of two MS2250 amplifiers in a common heatsink. The heatsink is nickel plated and does not include a bottom cover.

MINIMUM SPEAKER LOAD IS 4 OHMS BRIDGED OR 2 OHM STEREO.

Here's how to bridge the amp - If you have two RCA inputs cables, use both input jacks and set the STR/BRDG switch to STR. The BRDG setting ignores the right input jack and allows you to use the left input only. Connect the speaker load using the left + and right - output jacks.

There's no need for a dedicated fuses for this amp. Each side of the MS1000 has two 60 amp AGU fuses inside to protect itself (120 amps total). However, for competition you may want one anyway to meet the "easy and quick access" judging rules. If the amp were mounted upside down under a quick opening Plexiglas panel or something, that would take care of it.

Never let the chassis of the car contact the amp's heatsink. The heatsink must be isolated from the car on an amp rack. Allowing contact would cause alternator whine since audio ground is common with the amp's heatsink.
