How does posting about an entirely different truck have any bearing on this question?My 2 cents is i would put power to them. My boss had a JL8W3 and a JL 300 X 4 amp installed in his dually. Channel 1 and 2 for the stock door speakers and 3 and 4 bridged for the sub. What a difference it made in the sound. Made the stock speakers sound like good speakers. If you got the money put new speakers in also.
x2 . . lol @ fridge magnets bigdog.The stock speakers are junk. Anyone that has ever removed one can attest to this. I have bigger refrigerator magnets then what is on these speakers. They are easy to replace and even an inexpensive set of aftermarket speakers will be worth it. Otherwise you are just going to make the bad sound louder.
my thoughts in red.I was considering an alpine and powerpack, but experts have told me that a 4 volt output kenwood coupled with a quality amp and quality speakers (amp matching the speakers' RMS as close as possible) will give the best possible sound without going overboard and spending a fortune.
thats true of matching any HU, amp, and speakers. i has nothing to do with the voltage.
An alpine HU, powerpack, and lower quality speakers (50ish RMS) will sound great, but getting a 4 volt kenwood HU, dedicated 60-100RMS amp (high quality wire), and mid grade 1-100RMS speakers (high quality wire) will sound many times better. i promise you that i could hook up an alpine system with there power pack and a kenwood system with a 45 or 50 w amp with the same speakers and you couldnt tell the difference.
In addition, if you're going to replace stock speakers, you really should replace stock wire, so you might as well get a dedicated amp.
not really. you can easily run 50w through the factory speaker wire. go higher than that and its time to run larger/better wire.
