first off i fell in love with pioneer sub woofers back in 2008. I started with a 12" w307d4. It pounded. Then i had two 12" w308d4 they pounded. Now i hav the two 12" w309d4. Man the pound i have them hooked up to a hfi hifonics 1000D amp wired down to one ohm. I can be heard frm a block away, when i pull in gas stations i shake their store. i would reconmend getin a 3/4 mdf box though for better sound, up to a month ago i had a 1/2 mdf box and it sounded great for a while but after a few months i noticed my screws was half way out my 1/2 box from bangin so hard. So now i hav a 3/4 mdf box and its even louder. Would reconmend this sub for every one you cant go wrong. Wnd dont do like i did by buyin a crappy box buy a good sub box for these awsume subs. you wont be disapointed.

I got this sub hooked up to a phantom series ph1500.1 amp wired at 2 ohm and its great. It really surprised me with the lows it can hit. It has no problem vibing on the high bass notes like a 10" but when it drops down on a low it's crazy how well it produces the bass. My friend owns one of these and he has it way underpowered but has a full pioneer system and it still sounds soooo good. Highly recommend this sub. I know a lot of people are hesitant of pioneer but trust me they have definitely stepped their game up recently.
