one of my good friends has a couple of these, not close to my type R's lol but the have good sound quality not the biggest boom but you can hear him comming.
i got two of these with a ported box and boss 2000watt amp in my 2002 maxima. loud as hell! none of my friends will ride with me.
Man these damn things hit! I got two of these in a ProBox hooked up to a Kenwood 1800w amp and damn youll here me coming a good 7 or 8 blocks away. Ppl know its me before they even see me. No joke
i have one of these hooked up to a 500watt rms kenwood amp and these things hit hard you can feel it in your chest,it is the best quality speaker for its price that i ever owned,it also hits the high notes like no other
i bought 2 of these and have them runnin off a 1000wattn alpine amp and it outperforms my friends rockfords and my other friends power acoustik 12 prolly the best deal i've ever got A++
Great Sub, definite upgrade from previous, much cleaner tighter bass only complaint is, when an ohm meter is applied its actually more like a dual 8 ohm sub not a dual 4 ohm
