well, i finally got my box built and a set of RE8s in my hatchback.
i did a dual chamber box with .48 cuft for each chamber. pretty standard build using 1/2" MDF, screws and liquid nails. i have 150rms in stereo for each of the subs.
i am comparing this to my old setup, a single audiobahn aw100Q with 300rms mono in a sealed .75 cuft box.
the sound is much cleaner and tighter with the RE8s. i love to feel bass drum kicks in my back. i am VERY impressed with the clarity. with punk and other speed metal music, the subs stay clean and very accurate. with the same music the audiobahn turns into a muddle of crap and cannot move quickly enough to respond to the double time bass drum hits. with the RE8s each one is defined and solid. it's EXACTLY how i want my music to sound and i am VERY impressed with the sound for the price
RE8s get a 10 from me for being the best sounding setup i've owned. 4 of these mofos with 150rms would sound ****ing amazing!!!
