I don't know if those speakers are any good but once you see what's in there anything will be a 100 fold improvement!
For the same price, I got some Fli 13cm components from Vibe on Ebay and they are brilliant, coupled with an aftermarket headunit, IMHO. Some people will claim to only buy £100+ but the days of me spending £££'s on car audio are long gone! Plus you have a V6 sound system!
One thing to be aware of is that the original speaker covers might not sit flush as the new speakers are bigger and make sure you have some superglue to hold the tweeters in. Also, I wouldn't bother with the rears, just bias the sound to the front.
Hope this is of some use to you? Oh, here's a link to the speakers I bought: http://cgi.ebay.co.uk/FLI-COMP-5-13c...#ht_991wt_1139
The crossover with the Fli's is very small and easy to mount inside the doorcard aswell!
