Hey everyone, you have a great forum here. I have alot of experience with the mechanics on my 1992 LS400 but very little audio/electrical! I would like your opinions on a system upgrade I want to do. I have reserched alot in this forum and I want to maintain my original Pioneer radio head unit and CD changer but I want to upgrde my speakers. Here is what I am planning:

200W mono sub amp fed by orig sub speaker leads through LLC, powering a MTX thunder 4000 8" Sub ( No enclosure planned)
250W 4-channel Amp fed by orig speaker leads through 4-channel LLC powering Boson Acoustic SX50 5.25 Components (65W RMS) in front and Boston Acoustic S55 5.25 two way's (35W RMS) on the rear.
I will modify the existing speaker enclosures with a dremel to take the 5.25 speakers. Does this system make any sense. Do I have the correct amp power? Should I not put a two-way speaker in the rear doors? I am not trying for the best sytem just an ujpgrade from the orignal system without losing my headunit and CD changer. Any comments would be greatly appreciated!

 

Anyone? I promise to ignore the wizard behind the curtains!

 

sounds good, is that sub a good free air though?

 

I think it is. I ahve attached a PDF of the tech specs on it. It was given to me new. It is an 8" sub. Just goes to show how much I know about audio!!! If it isn't a free air do I need to build an enclosure?
