Hi christo.
My hubby tells me that if you install quality components up front there should always be an improvement, but even a decent head unit will struggle to get the best out of them.
A dedicated amplifier will push them harder and produce a better, fuller, sound - even at lower levels. Most people cap the cabin speakers at a set frequency so they don't have to deal with the low bass that they will struggle with. Somewhere between 80htz and 120htz usually.
Some people think its not worth amping the cabin speakers if they are going to be filtered and just throw a sub into the mix. But as well as a more powerfull sound, amplified components create a better clarity and stereo separation. This then works in tandem with the improved bass so the overall sound is better and not just a thumping bass line.
Don't worry about the thread-jack - if theres a question that needs answering then it needs an answer!
