Sic Posted June 2, 2014 Report Posted June 2, 2014 Looking for some advice on a sub to match my amp. Its a Rockford Fosgate 360a2 (http://www.crutchfield.com/S-yOZJ6PIXEye/p_575360A2/Rockford-Fosgate-Punch-360a2.html#details-tab) I am thinking of going with a Rockford Fosgate P2D2-12 http://www.rockfordfosgate.com/products/details/p2d2-12 Just wanted some input if this is a good choice to match the output of the amp? Second part is I would greatly appreciate a enclosure design. I have tried to download Torres box calculator but I had issues so I figured I ask instead. Amp = RF 360a2 Sub = 1x12" RF P2D2 Vehicle = Dodge magnum, for space I have 39" W, 15"H, W don't matter (back cargo area) I mainly listen to metal, sometimes old school hip-hop. Thinking tuned to somewhere between 32hz-34hz I'm just trying to upgrade and add some bass to my daily. Any advice would be great.
Sic Posted June 2, 2014 Author Report Posted June 2, 2014 Guess I should have added, I prefer ported over sealed
timc31610 Posted June 2, 2014 Report Posted June 2, 2014 You may want to get d4 coils instead of the d2 coils. With the d4 you could run the amp at 2 ohm bridged for 360+ watts. A 1.8 to 2 cf box with around 30" port area would sound nice.

timc31610 Posted June 2, 2014 Report Posted June 2, 2014 You are correct, I didn't read down far enough. Do you have a reliable way to set your gain?

timc31610 Posted June 3, 2014 Report Posted June 3, 2014 Then yeah, stick with the d4. My Build Log 94 Civic http://www.stevemeadedesigns.com/board/topic/188644-94-civic-4-door-build-loq-suggestions-wanted-will-be-super-slow-mo/ Faceebook reluctantly

Sic Posted June 23, 2014 Author Report Posted June 23, 2014 Im still trying to come up with a enclosure design for 1.79 cu.ft. tunes to 34Hz. Reading through some other post I may have found one that will work. Also reading about sub and port placement. Am I correct in thinking for my vehicle, its a station wagon, that for best output I should have the sub facing up and the port facing rear?
Joe X Posted June 23, 2014 Report Posted June 23, 2014 Here is a suggestion on the enclosure, power: to sub rated, amp subsonic filter to 28Hz, port clearance 2", figure is just an assembly guide:
