Summary: Man..this sub's hit hard in a custom ported box that I made...2-12's!! and with the Prime R500X1D giving them 500 watts rms @ 2 ohm load (250 rms for each sub) hit hard more than I spected and my wife never like music loud but.
Summary: Love this speaker. My only complaint is that the clearance between the speaker cover and the speaker itself is tight. I worry that the speaker will rub up against the cover and produce a hole. Other than that, no complaints. Sounds amazing!!
Summary: The sound is freaking loud for only spending $160 simply because they are efficient enough and big enough in the box I chose Has a nice grille available that goes between speakers and outer grille to protect speaker even though i don't need cause the box is sealed for front of speakers
Pros: Perfect value for such loud sound, clear bass in this band pass box or whatever it's called
Cons: I'm not really going to consider this a negative, but the trim rings are a tight fit at 13in diameter, fits great in the box tight for anyone who needs to know
Summary: purchased 2 12's for $100 each. I have them in a bassworx ported box with a alpine m500 amplifier wired @ 2 ohms (roughly around 250 watts per subwoofer). i wasnt expecting a whole lot from these since they're only stage 1's. but after testing it in my car, they pound pretty hard for what they are.
Excerpt: Mein heutiger Bericht handelt von der Rockford Fosgate P1 S 412 Box, die sich mein Vater vor einigen Monaten für seinen Mercedes E 320 CDI gegönnt hat, da er einfach der Meinung war, wenn er schon öfters mit dem Auto unterwegs ist, dann soll da auch ein gescheiter Bass herauskommen.
