if you are keeping the stock speakers, it wouldn't help really. It might clean up the sound a bit but the speakers are still 25 watts (the woofers). I saw the alpine power pack a while ago but its more geared towards someone who has an alpine HU and wants a little bit more power than the HU can put out. I dont feel its too applicable here.
You could keep the current stock HU and buy an outboard amp and new speakers, that would make a marker improvement provided your buy some decent equipment. You dont have to spend too much either if you play your cards right. If you know how to install equipment that will save you money too. When it comes to audio (home or car), garbage in garbage out.
