[QUOTE="Jcsaudio, post: 8631759, member: 673752"] The current JBL GTX 500 I have just got moved to my Sienna and it’s running the Alpine sub in that van, which sounds the same as it did with the Alpine MRP 450 (no surprise there). I had a JBL Club 5501 but the mosfets for the power supply fried while I was testing with a test tone, although that was my fault really. Pushed it too far I guess. In my amp guts video the GTX appeared to be better built than the Club 5501 and it did dyno higher by bigblank69. The Sundown SD3 is installed in a modified/braced sealed truck box with a net displacement of .5 cubes so I plane to give it up to the full 500 watts RMS it’s rated for by Sundown in that size box. It’s always good to have a little headroom though so anything rated higher is obviously better. The Alpine I’m reading about tends to dyno in the 530-545 watt rms range. The SoundQubed amp is a 1 ohm stable amp though that they claim is rated 900 watts rms at 1 ohm. If that’s true and it’s clean than that is incredible for that price. Tough choice here, Rockford has a solid following of very satisfied customers. [/QUOTE]
