You can by a replacement plate amp at partsexpress. It will work, but it probably won't be a drop in replacement. Take measurements. Otherwise contact the manufacturer for options.
What is the best way to replace a blown sub amp?
Well, a little emergency at my Bakery/Cafe. A huge power surge took out a prep table, beverage cooler, my main oven, ten or so fluorescent ballasts, the phone system, cash register, exhaust fan...and my Creek 5330! Also it blasted two subwoofer amps. One of them is a cheapo one in the production area...not too worried about it. The other, in the main dining area is a nice Acoustic Energy Aelite Sub. Paired with Aelite 2's, an NAD 355 amp, Musical Fidelity V-DAC, and Apple MacBook running Pure Music and lossless files, the customers are usually treated to great music, even at a fairly low level. The speaker seems fine. Do I buy one of those plate-amps from parts express? Do I get another amp and crossover? Thanks....Oran...your Village Baker...(www.villagebaker.us)
