Have just purchased an '06 LR3 from a friend and it allegedly needs a new amplifier. The PN on the original one is XQK500091, but upon searching for a new one, google turns up nearly nothing. Ebay boasts loads of 93's and 95's, but no 91's, in fact the only place I can find a 91 is on Roverland for almost $400. Looking to do a little better than that on price, so I'm hoping someone has some good news for me in terms of compatibility with some of the more common amps. This is for a non-14-speaker audio system.
