Ease of Use
I have gone through 3 Alpine Type R's using the PDX1.600, after my warranty ran out on the Type R's. I saw that this was 1/2 off I had to order it because the price break was more than then actual sub itself, and have a set of Boston computer speakers that have never let me down! After receving the subwoofer I was a little sceptical because it looked pretty shallow, and the magnet was smaller then that of an Alpine Type E. After messing with the Gain on my amp I didn't even have to break it in cranked the gain to full and it RAILS in a sealed .95 box!!! I have to say its not quite as deep as a Type R (much bigger magnet and four times the price with warranty) but for a cheep sub it has really thrown me off! I probably will stick with the Boston brand from now on. Sweet sub, no regrets.
Pros: Takes all of the clean 681w my PDX can push through it.
Cons: Blew a fuse (fuses being the coolest idea ever) and had to unscrew it from the box to replace, kind of a pain, but WAY better then toasting the sub. Replaced with 5 AMP (instead of 4 AMP) and good to go all day!
