I have a set of Dove grey (can be painted any color) custom kick panels that will hold up to a 6.5" speaker and tweeter..
these are made by a company called Q-Logic
I paid $350.00 about 2 years ago but they are now selling brand new now for $200.00 US + shipping
They are made of same plastic as original kick panels (these replace ur existing kick panels)
pics to come
i am asking $95.00 for both sides
