The reason you may have lost bass is either because the freq's of the new speakers, are too high (EXAMPLE 60hz-30000hz) Where, as a good all rounder with just enough bass, would normally go as low as 25-30000hz. The stock speakers have a greater freq band than your new ones. BTW! Just a side note: I disliked the stock speakers, so I went with some cheap DUB269 Audiobahn, & I must say, they carry more bass than the stock, still not enough, but you can really notice the difference, it kinda makes the audio feel way more whole :) Thanks for your help. Just another question is it better to get aftermarket speakers that have a lower power rating than one with a high power rating? Since i won't be powering the speakers of the amp i was thinking speakers with less power would run better through the headunit.
