That was also another thought but I didn't know what made the most sense. Due to the large volume of the truck, I thought adding another pair of amplified speakers would help in that department.
I have adjusted the frequency at this point to keep a lot of the "lows" from going the the components so they didn't have to work as hard and that I could squeeze a little more volume out. I am just missing out on the drum punches with this setup.
I think I have enough equipment and flexibility to make it happen but I just don't know the best solution. I know the 9887 is flexible in it's frequency but also complicated to understand as well. I'm no pro and start to get a little dizzy reading some of the more in-depth posts but I'm will to do what I can.
I did find another post where the amp was under the 2nd row seat but I don't want to suffocate it if the seats are lying flat. I'll take another look at the clearance.
