Chop: Might be a dumb question but are the Infinity's replacing your 4 main stock one's in your VX??
I getting ready to upgrade my Pioneer head unit and the China(ebay) motorized monitor for an all-in-one Pioneer model AVH-P4900DVD touch screen also a Pioneer CD-IB100II iPod ADAPTER and a so-so Kenwood powered sub and I still have the stock speakers and will need to upgrade...I'm not after a crazy loud system just a nice comfy sound..
Yes, these are direct replacements. A bit of fitting is required for the rear, but not much really. No plastic will be cut. They will handle much more power than stock, but they require little power to operate well. Pretty efficient.
