So I have an extra, single 6x9 speaker. Recently picked up some great condition used JBL power series something something 6x8s and the seller had a single 6x9 he threw in since it had no match. Very nice speakers and the 6x8s sound very nice in my F150 but I hate to scrap a perfectly good speaker just because I don't have a pair to run. Is there any good way to run a 6x9 solo? Don't really need it but it would be nice to throw it in a speaker box and have a mono setup if I ever needed it... Everything I've read makes this sound like far more effort and cost than it would be worth, though.
