OK to place amp on top of subwoofer?

just put a piece of foam under the amp and dont worry about it. i have done it several times. you will not hear any difference in sound and the foam will absorb any vibration. some of these people on here know just a little to much. enjoy

10-4 Sean. Good take Danner, and I agree if it has to be done, using a de-coupling approach would probably be best, ie the Vibrapods. There is a good reason Steve McCormack put 6 large Sorbothane-like feet on his 90 lb. DNA2 amp. Cheers, Craig

Although powered subs contain power amps those amps are only playing bass frequencies so vibration control is much less an issue regarding sound quality than in an amp playing full range. As to the issue of amps vibrating apart it may be an idicator that this is less likely.
