Hi There, Have you checked the 3 fuses that clip onto the main amp board? You can access them by undoing the two screws that are on the top and the bottom of the sub. They have flat large heads and you will need a hex key to unscrew them. If it is one of the fuses that has gone it will either be discoloured as in burnt or you will see the metal inside has split. Simply replace these with a new fuse and hey presto you should have eradicated the popping. If you need any parts for the sub or fuses then www.LondonSpeakerShop.com will be able to supply them (that is if you're in the UK). Hope this helps. Grant (from www.LondonSpeakerHire.com)

does your swa1501 get hot just being switched on ?
sounds like your output transistors breaking down or your dc to dc rectifier is shorting this would dumping high voltage to the speaker. I guess your speaker coil is burnt . check Q4,Q5,Q7,Q12.Q14,Q15,Q17 and Q18 these are all mosfet transistors that commonly break down..

Where to purchase a bracket


Unfortunately there are two standards for the pole diameters. Some of the smaller poles have caps to accomodate the larger brackets. First thing is to measure what you have for poles and the two sizes of mounting holes. Many of the mounting bosses are standard and available online here is an example:

Sub will not power.


I reckon there is a good chance you've got a dodgy mains transformer, or perhaps a blown internal fuse. Sounds very much like the problem is on the AC input board.
