So my second row speakers finally shredded, and I'm wanting to upgrade to the 6 1/2", 6 1/4"...whichever. I've read several older threads but most of the speakers are no longer available. I'm hoping to find a pair that will go in with no cutting and very minimal mod, and not looking to spend much. I don't mind if they flush mount. Suggestions for minimal or no mod 2nd row speakers that won't cost $$$? Cheers in advance.
