Alright, so after going thru hell and back finally wiring my car together I have my system in there. Panasonic 8100 deck, Stock Pioneer speakers all around, 2 12" Pioneer Premier W3004SPL Subwoofers (1000rms), and a Hifonics 1606d Amplifier for the subwoofers. After putting it all in and getting her going the car sounds great. It has much better sound quality than I expected, but the one thing missing is the massive SPL bass. I had this same system in my brother's cutlass and it was MUCH louder. I believe with the way lexus's trunks are setup it is harder to get noise into the cabin. What have you guys done to allow more bass to travel into the cabin?

Should I fire my subs towards the seat?
Maybe some kind of new box to fire into the car? Let's hear it.
Cheaper the better!

Edit: Car is 1993 ES300

 

Remove the sound deadening stuff that seperates the trunk from the car's cabin.

And did I read that you're using a big amp and big subs and using the stock speakers powered off the head unit?

 

The stock speakers are 4ohm pioneers. Off my head unit, they sound great. As I said, Im out for SPL, not SQ. I removed the plastic piece and metal cross behind my backseat. What other sound deadening do I remove?
