  1. From my experience, they can get loud, but aren't the nicest on the meter. I had my 15" XL on a little over 2k and managed a 145.0 even at 36Hz. That took A LOT of work to get to that number. lol. But to the ear, it was always pretty loud on anything I put in there. Probably because the car peaks around 43Hz and 43Hz is a good "loud note" in a lot of songs. lol

  2. Friday.... Friday... 18... 19... 20. It's April. Haha yeah, with those prices, as long as you wait until you are in good shape to maneuver power tools, you can have yourself one damn cheap box. (In terms of cost. lol) Take pictures. Pictures are always nice.

  3. yea ive talked to u about that 15 remember :P im planning on running --> http://www.sonicelec...te-R750-1D.html

    this is going in my alero.

    Oh yeah man I remember. Duh. lol

    The Fosgate Prime Digital amps are actually pretty good. I put one of those very same amplifiers in the other day in a 2011 Silverado and it actually tested 964rms on it's birthsheet. Yeah with that amplifier, i'd aim closer to 2.5-2.75 honestly for the P3. At 3.0 i'd be worried about losing cone control on lower notes.

  4. I still think 3.0ft^3 is a tad on the big side if you plan to send it much more than it's rated 600wrms. But tuning and port area looks good. Looks as if you took everything else into consideration as well as far as displacement.

    If you want to keep height and width, you'd have to shrink depth in order to drop net volume. That would change your port measurements up too. So it'd basically be plug and play until you got the tuning and port area measurements back to the same ballpark.

  5. Damn you. lol

    And when I said to slim the width, I meant to slim to port width to drop the port area number down.

    And 3.5ft^3 is just a generically thrown around number. A lot of drivers may fit into that category, but not all of them. My 15" DC Audio XL wanted 3.0ft^3, but I was also running 2.5k to it. When I sold it to buy another identical sub down the road, I had 500wrms to work with, so it like 4ft^3 for the time being. DC recommends 3.5ft^3 I believe. It is typically application variant.

    The P3 though is made from smaller and lighter soft parts than those of your typical brands you see being thrown around on here. We sell Rockford Fosgate at our shop so i've been able to play around with them a bit. I'd honestly aim for around 2.5ft^3 as long as you only planned to run rms power to it. What amplifier are you planning to run in your application?

    And nice car, I used to own an Alero back in the day. lol

    Ignore the wing... lol

  6. The generic number used is anywhere between 12-16in^2 per ft^3 for a slot port. With too much port area you will have somewhat of a "peaky" response and your power handling will drop since you would have a much greater risk of unloading issues where your driver will bottom out at frequencies lower than tuning a lot more easily. For the Fosgate P3 series i'd probably aim for around 14in^2.

  7. The common port walls box refers to the top, bottom, left, and right sides of the port, therefore it should be three...

    When you type in port length, that is the length following the center of the port back, and then into the box since it will be in an "L" shape. Physical port length is the physical length of the wood used to create your desired length.

    Corrected. :ninja:

  8. just a question..... y do you NEED a cheap flip out. you know the cheap ones will break in like 3 months right

    To clarify, not looking for knock off brand garbage. Just an older head unit from a reputable brand for around 150-200.

    For instance I used to have an old avh5700dvd I picked up for 200 and absolutely loved it.

    Nice link bro. lol Strange Music FTW.

    And OP, your best bet for a flip-out of reasonable quality for that price would be your local Craigslist honestly. Wherever you got that flip-out for $200.00 was a steal if it was in good condition.

  9. Ninja's while typing slow. I vote 10"s or a 12" in a 4th order and run the vent into the armrest location. Or possibly a ported box, but still with the port through the armrest. People have been lucky with high sound pressure with zero spoiler issues, other have cracked plastic spoilers doing high 130's and low 140's. It really depends on resonance and the integrity of your vehicle.
