I have not purchased a Rockford sub for quite some time and just bought 1 12" P2 and have also bought a Punch 300.1 amp.
In the past I have had a couple 10's and a couple 12's in a vehicle but I never ran enough power to them and the enclosures were big and the bass did not seem to have that "hit" when listening to rock/metal.
Can anyone tell me any dimensions for an enclosure for 1 P2 12" that will give it the hardest hitting bass for rock/metal?
One of my buddies says ported, the other said sealed, I am lost as what to do. |

| I forgot to mention this enclosure is going in the trunk of a 97 Honda Accord. |

| for that kind of music id suggest the sealed style box. it will hit cleaner and be more accurate than the ported box. theres a box advisor in the product listing under the subwoofer that can give you some approximate dimensions for the recommended box. it suggests 3/4"mdf rectangular box H= 14.125" W= 18.75" D= 10" box will be 1.07cu.ft. before woofer displacement. |

Thanks for the help whitling.
So would making the box a little smaller, or bigger effect anything. I only ask because I heard my first P1 a few days ago and it sounded really, really good for what it is, and the owner had 1 12" in a sealed box @ just under 1 cu.ft.
Would the sealed box still give me hard, deep responses? I mean if my girl wants to here some R&B, I would like it to sound good. |

| the box size definitely has an effect on the overall performance of the sub. smaller sealed boxes tend to be a little more boomy. for all around music though id still stick with the recommended size. the sealed box wont be as loud as a the ported box but overall i think sealed boxes are the way to go for daily listening. it should still hit pretty decent with that amp and if you end up looking for more like most of us end up doing. you can always add a second one and just wire the amp to 2 ohms. |

| most ported boxes do not allow the sub to respond quick enough to sound good with fast hitting rock songs or any thing like that. i use a ported box in everything but thats because almost all i listen to is heavy hitting rap. my 4 p2d212's hit harder on most any song than any car around the area im from. |

Thanks for all the help.
So if I have a sealed box and do listen to hip hop, it will not be good at all?
I mean I want to best all around box but I do listen to Rock and classic rock the most. |

sealed boxes sound good with most anything as long as its built right. classic wont sound good with a ported box lol. id stick with the sealed box if i were you. it wont sound bad with hip hop it just wont be quite as loud as a ported box.
No problem. anything i can do to help out a fellow bass head.. =) |

a ported box will be louder then a sealed box at some freq. the tuning freq determines the "peak" and depending on how its designed and such ~ twice as loud at that point. so if you mainly listened to hip hop ported tuned low makes sense its louder and for 95%+ of the music you wont notice the difference.
on classical and rock thou you will notice. it will be more sloppy and every peak has its valley so on those higher frequencies you ***might*** have less output then the sealed box.
so in your case its real simple. the only option is a small sealed box for the tight bass and a flatter response. the downside is its just a P2, they are great speakers and all but a single p2 in a small sealed box may or may not be loud enough for you. ya its going to be loud but its not going to rock the block, but again in your situation a small sealed box is the only "right" thing to do, and if its not loud enough be smart and buy another one and bigger amp vs blowing the sub |

Cool, again thanks guys, you have made a tremendous difference.
The reason I have only one now is I just want a decent sounding system, nothing super and I only had a little $ to spend. I mean the best system I have ever had was 2 12" Kicker Comps in 1996 with 1 Punch 75, yes just 1 and it sounded good to me, so I figure this new system will be decent for me.
Plus the price I paid for everything was amazing, I thought it was at least.
I already had a JVC head + 4 Kenwood KFC components so all I need was an amp for those, and then a sub or 2 plus a dedicated sub amp.
Punch P2 D412 - $98.99
Punch 300.1 - $97.00
Mb Quartz 200 W - $73.00
2 amp JB Link amp kits - $ 36.00
That is it, low price, decent sound....I hope.
I was thinking of another P2 and another Punch 300 since I got a great deal but that might be quite a bit for the trunk of my Honda.
So let me ask this. If I make a box this weekend at 1.07 cu. and lets say by accident make it like 1.06, or 1.08, will this make a huge difference? I am just worried about it and wonder if I should just buy a box for $50-$60. The reason I hate to is because I just like to do things on my own, makes it that much better when I am listening to tunes. |

| no it wont... i would try doing a slanted face or a slant on the back if you think you can pull it off. it wont make a tremendous difference so if you cant dont pull your hair out but it will help get rid of any standing waves |

Cool, thanks again.
I would like a box to fit right into that little "cubbie hole" in the trunk of the Accord, so I have the entire trunk space left. I think I have about 33 x 15 to work with and it really narrows a lot towards the top, so I might have my work cut out for me, considering I have never made an enclosure in my life.
So I guess my checklist is...
1. 3/4 MDF
2. Liquid nail
3. Screws
4. carpeting |

| sure looks like it should work. it has the slanted edge to help make the most of you trunk space. optimum space is 1.02 but recommended is between .7 and 1.8..after woofer displacement your still going to have .823cu.ft. of internal space for it which isnt to bad. |

| sure. to be honest a small squarish box with slanted edge facing the trunk would probably get louder then something crazy packed in the corner of the trunk facing the side |

I just found the box at another store and they told me the box specs, and here it is.
Top depth: 9.25"
Bottom depth: 12"
Width: 15.25"
Height: 13.5"
.9 cubic ft
So if I made my own box at around 1.07, there would hardly be a difference in that and buying the above? If that is the case, I might as well spend $30 or so and save time, and hassle for myself. |
