I recomend Alpine SPR-57LS Type R series. 300w max peak 60wrms. speaker link
I have two sets of Alpine SPS-570A Type S. They were afordable replacements for my Pioneers. Cost about the same. Sound good off the amp, but had to wire aditional in-line tweeters on the front two because of the low pass filter on the amp I'm using. I'll upgrade to Type R later but I'm cool for now.
