Re: Door Speaker Upgrade
I put a pair of KRK 6" studio monitor speakers and 1" synthetic silk domed tweeter using their crossover (properly voiced for the pair) on both doors when my driver side woofer blew. These have glass aramid cones and the semi-shallow basket that work very well off-axis but I need to upgrade the factory amp to push these 4 ohms drivers a little more.
They can pump out decent lows down to 50-60hz but you really have to push the volume to get there.
To get more bass at lower volumes i hope to install a dedicated subwoofer amp and a pair of 8" Cerwin-Vega subs behind the seats - hopefully sometime this summer..
