**READ THE LISTING!!!!** REPAIR SERVICE ONLY!!! YOU ARE NOT BUYING AN AMPLIFIER OR A SUBWOOFER!!! WE ARE OFFERING A REPAIR SERVICE ONLY!!! Do you have a Mackie SWA-1801 subwoofer that needs repair? Simply remove the amplifier assembly, box it and ship it to us for fast repair in 3 days or less! We replace all burned and shorted components with original parts, fully test it and ship it back to you for a flat rate of $219 plus $25 return freight. Your amp will be returned in a new heavy- duty box with new packing material. Your repair includes ALL PARTS AND LABOR, including ALL SIX FILTER CAPACITORS if needed! Other shops charge an extra $80 for this. We do it right- no extra charges! 90 day warranty on parts and labor! NOTE: You MUST check your woofer for a shorted voice coil! Often the woofer will fail and cause the amp to fail, or vice versa. The woofer has a 4 ohm voice coil which will measure no less than 3 ohms on a multimeter set to the lowest ohms scale. Please message us or call our customer service line for more info on how and where to send us your broken amp. Our number can be viewed in the "ask seller a question" link. Please note that this listing is for a flat rate repair service for your module. You are not purchasing a module- only the repair service.
