Speakers were a night and day difference. Once you take the stock speakers out, you'll wonder how they even made sound as poorly as they are made. The magnets on them were so small. Swapping the rear door speakers may not even need a sub for some, but mine was just sitting there so I threw it in. The dash speaker is a 2 1/2 inch-ish speaker so mine sounds more like a mid-range with the bass removed, which I like...I've had some tweeters the are just too much high freq you can hear coming from that area. I'm not really brand specific for loyalty, but the Kenwood speakers were designed for this type of application and they do sound good. 2 1/2 tweeter and 6x9 mid.
The rear door speakers allegedly roll off base when turned up, which I believe to be true as the LC2i has a certain point that the bass comes back in as you turn it up.
The Kenwood speakers were $200 at a local stereo shop, much cheaper than Crutchfield, and Amazon is not an authorized reseller so I went local with them.
