i see no reason it would be sending bass to the tweeters...there are cross overs and the system sounds perfect...there is nothing that shows any sign its damaging anything...and you know what if it blows them up so be it....i will take the 10x better sound with the slim chance i need to put better speakers in...this system was PATHETIC before ive had 20 dollar bluetooth speakers that could produce better audio.....this makes this much more like a system that comes in a high end suv. Again i hear no sign of audio degradation or damageWhy would you expect to hear "bass" from the tweeters? The tweeters will not audibly reproduce bass frequencies. The bass power however could be still delivered to the tweeter speaker coil - this is the danger. If the tweeters are rated at the same power as the 6 inch drivers then no issue but tweeters are generally not rated like this - they will have a lower power dissipation rating (as the ear is more sensitive to higher tones and thus a high power rating is not required). A simple series capacitor will isolate the bass frequencies from the tweeter. If this can be done without removing door liners then very nice - I will be checking the wiring for the most accessible location to add said capacitors. What size capacitor to add - well the tweeter impedance will be required and the desired cutoff frequency. Any one have an idea what impedance the tweeters are? 2/4/6/8 ohm?
