    That’s awesome. I bought a Rockville rock Crusher 10in subwoofer and the speaker and plate amplifier where so under par . I already replaced the speaker with a Rockford Fosgate prime and the sound quality is 500% better. Now I ordered the SPA250 to replace that cheap amp. I’m lucky that it will fit into this cabnet perfect. The ohms of the original speaker was 3.8 and Rockford Fosgate was 4 ohm . I can’t wait to hear what a difference the Dayton plate will make. Thanks for reading.

    I think what you did is awesome. I’m doing basically the same thing. I purchased a 10in Rockville Rock Crusher home sub. The sound quality out of the box was so bad. No low bass , bad distortion at any kind of volume. So first thing I did was buy a Rockford Fosgate Prime. That alone improved the sound quality 500%. Since the cheap speaker I removed was 3.8 ohm, the 4 ohm Rockford Fosgate was a good match. Now I’m ordering a SPA250. Can’t wait to hear the difference. Thanks for reading.
