New Speakers Note 1: If you're going to keep the low-powered factory head unit, a sensitivity of 92dB or higher will give you best results.   Note 2: Though I installed Infinity 652i's with no problem, a few people have been unable to get the front-door grilles to reseat properly due to the tweeter height. You might want to consider Infinity components in the front doors or using Polks instead. Rating the Results   1 Not Bad For Factory: this is what you get stock. A little bass thump & tweeter sparkle but mostly muddy middle.   2 Pretty Damn Decent: Upgrading the four door speakers and the tweeters gets you here - better mid-to-high, more clarity.   3 Kick Ass: Would take a lot more than just speakers...   Dimensions of the Infinity Reference 652i speakers as indicated on the box. Infinity and factory speaker. Mounting depth is almost identical. Tweeter and rubber surround add about 3/8" to height of Infinity. Speakers with Crutchfield. adapters attached. (Adapter ends had to be crimped to get secure fit on speaker terminals.) This metal ring is part of the Infinity install kit. It allows you to use the existing holes, but adds too much height and prevents front grilles from re-seating so I removed it and mounted the speakers directly to the door. Front speaker mounted (without Infinity metal ring). Speakers with less mounting height (such as component mids) would probably work fine with the ring. Rear speaker connected to factory wiring with Crutchfield adapter. The rear speakers would also work fine with Infinity's metal ring since the enclosures have a lot more surface mount room. Rear speaker installed.     close window close window
