What do I need for mid bass in my car audio system?

Question

I have a Pioneer DEH7800MP head unit running four pioneer premeir 6x8 door speakers. And power acoustik amp running 900 rms through two 12" audiobahn subs in vented boxes. I have really good highs and really good lows, but i am missing alot of mid bass from my music. What can I do to get some mid bass in my car. I have a spare 300watt(150rms) amp that I can use for either my door speaker, two of them at least since my amp is 50rmsx2 at 4ohms. Should i amp my door speakers to get my mid bass or should i invest in a mid bass driver. If i get a mid bass driver i have nop problem finding room for it, i just need to know if it would be a good decsion to get. What brands of mid bass drivers would you reccomend. Here are some i am considering, are they any good or are they worth it.... #1 http://www.sonicelectronix.com/item_3475_MA+Audio+MA65B.html

Answer 1

Install sound deadner on all your doors. It made a big difference for my mid bass. B- Quiet is really good for the price.

Answer 2

whats the rms of the 6x8's? you could upgrade the front to a 6.5 component set like the 1 i have here

run that off the spare amp until you can get a 4channel if you dont have the money to yet. i would upgrade the other 6x8's too if you have the money, pioneer speakers are ok but you can get much better. you can go with audiobahn 6x8's or get the same component set for the rear and then run a 100x4rms amp to it. it would be a lot louder than it is now since your radio is only pushing around 20-22watts rms
