Test fit my lil' subwoofer amplifier for my lil' bitty subwoofer.
It's an old Radio Shack 6.5 subwoofer with 4ohm dual voice coils and a staggering 20W per channel!!! The interesting thing is, for a ported tune of 33Hz, the box requires 1.67cu.ft.!!
I'm using one of the nicer Chinese TA2020 amplifiers, the Indeed. Looks nicer, anyway. We'll see how it goes. The HU I have has a dedicated low-pass sub out.
I'm going for low power/high efficiency. I just need a tad bit of low end for the really tinny sound of the stock NX speaker locations.
Here's the resulting sub box:
For the amp, I'm mounting it where the ashtray goes. I cut a section out of a thick clipboard, so it can slide in and out, but stays in firm with friction:
Going to have to test it out when the new HU comes in. It's a classic (to me) Kenwood EZ500 with big ass rotary knobs!
