You only need one!
I put an MTX Pro 400x5 under the passenger seat. Very close fit but everything clears.....only had to take off the return spring for the passenger seat.
Amp is 4x125 watts at 2ohm per channel or 4x50 at 4 ohm.
Sub amp inside is 200x1 4ohm and 300x1 2ohm.
There are 3 fully adjustable electronic x overs built in (front,rear,and sub)
Very clean, high quality, and one simple install!!!!!!!
I will post my pictures of this tonight!
The current model is the 405 I think.

Blue Thunder PRO400X5 Amplifier
--------------------------------------------------------------------------------
You'll choose the five-channel amplifier when you want a killer audio system. And you just want one amplifier to do it all. Drive the front and rear speakers, along with a subwoofer (and you'll pick Blue Thunder when you want low noise, high reliability, and the look of a champion).
Dedicated Class D Subwoofer Channel
External Bass Control Port
Front Channels: 18 db/octave Butterworth defeatable and continuously variable crossover (40Hz - 175Hz). The front channel has a frequency multiplier so you can change the crossover frequency for different applications.
Fifth channel: Class D subwoofer channel, with an 18 dB/octave low-pass crossover (Butterworth, continuously variable, 40-175Hz). With a Class D channel you get a very efficient amplifier, meaning more of its power goes to driving your speakers.
