[QUOTE="pwatts, post: 1169369, member: 146"] I agree with Shonver, repairing an OEM plate amp is seldom economical and often just fail again later, these things are just built with too tight quality margins, not to mention often encased in all kinds of adhesive compounds to avoid parts rattling or shaking loose. For resurrecting a blown sub, it's usually the amp itself. In that case (if the quality of the remainder justifies it), I've replaced the amp with an electronically & mechanically compatible class-D module with an adapter aluminium plate to fit it to the original mounting holes and powered it from the OEM PSU and feed it from the OEM filters. Other times in a more fried case, replace the amp altogether with an integrated amp & PSU module from ICE or Hypex. Filters can be done by shoe-horning in a miniDSP. Depends really on the quality of the driver and visual aesthetic of the cabinet how far one wants to go. I have built upto 3kW RMS with a plate amp, it's possible with the right time and budget. Normally 2kW is where I'd draw the line though before physical constraints, cooling etc. just becomes too hard. [/QUOTE]
