FeelDaBass Posted November 28, 2012 Report Share Posted November 28, 2012 I use RF's ported specs and it hits pretty decent. Sealed had more SQ though. But since my backseat doesn't fold down, I prefer the ported. Maybe tune a little lower.

Kade Posted November 28, 2012 Author Report Share Posted November 28, 2012 Should I follow RF recommended specs for a ported box? Or is there something better? I wouldn't, I did the sealed box design and it sounded great, but the ported design for my old Rockford P1 had awful port noise. I'm sure someone on here can help you out with a design though That'd be cool. My subs are in an overlarge box and it's just boomy; my subs work a lot. I turned it back a little and now I can barely hear them. I know it has something to do with how big the box is. I blew my P1 because I had it in a way oversized box, but it hammered. Start a thread in the subwoofer/boxes section, make sure to specify hoe many youre going to run, sub brand and model, sub size, power you're going to run, maximum dimensions and tuning frequency you want. I'd help you out but I don't know much about box designing. OH NO! I'd cry if my rig blew. I spent too much money for my budget when I put this all together. 2009 Dodge Caliber SXT (Silver) Deck: Pioneer X3600BHS Amps: RF P1000X5 Front: RF P16-S Rear: RF P1694 Subs: 1 RF P3D2-10 Cabling: Stinger 6 channel RCA, RF 4gauge kit, SkyHighCarAudio 16gauge speaker wire.

I made a MAJOR math error in my design and my box came out half a cube bigger than what I needed. I can't complain though, it got the job done and then some Link to comment Share on other sites More sharing options...
Sonic Posted November 28, 2012 Report Share Posted November 28, 2012 1.4 cubic ft net each, they sound good tuned to 36 Hz with reasonable output, If you are gonna tune higher then tune to 40 Hz, this is where you get maximum output but loose on the low end. I would recommend doing only two on that amp, the sound good with a clean 400 watts rms each. Link to comment Share on other sites More sharing options...

I would recommend doing only two on that amp, the sound good with a clean 400 watts rms each. They haven't sounded good since I installed them. Done everything I could to try to make them sound good. Just assuming it's the box. I have a question though. On my radio, I HAVE to chose between 50, 63, 80, 100, and 125hz for the sub amp to work at. Then I can chose how much to boost or decrease that frequency. If my amp is showing 35hz, my radio is at 50hz, but my box is tuned to 36hz-40hz...wtf? 2009 Dodge Caliber SXT (Silver) Deck: Pioneer X3600BHS Amps: RF P1000X5 Front: RF P16-S Rear: RF P1694 Subs: 1 RF P3D2-10 Cabling: Stinger 6 channel RCA, RF 4gauge kit, SkyHighCarAudio 16gauge speaker wire.

Sonic Posted November 28, 2012 Report Share Posted November 28, 2012 You need to understand how to get your settings right. On the amp you low pass at 80hz, Box tuned to either 36 or 40 Hz, subsonic set to (0.75) x (box tuning frequency). On the radio, set sub low pass to off or through, if it dosen give that option then set it to 80hz and then set the amp low pass a tad above 80hz.

For the time being, what would I set the subsonic for a sealed box? Also, would I but a highpass on my doorspeakers so they don't conflict with the subs? If so, would I use my radio or my amp? 2009 Dodge Caliber SXT (Silver) Deck: Pioneer X3600BHS Amps: RF P1000X5 Front: RF P16-S Rear: RF P1694 Subs: 1 RF P3D2-10 Cabling: Stinger 6 channel RCA, RF 4gauge kit, SkyHighCarAudio 16gauge speaker wire.

Sonic Posted November 28, 2012 Report Share Posted November 28, 2012 For a seal box just set it around 20Hz, I usually set it to Zero. High pass for front speakers about 100 or 120 hz. Link to comment Share on other sites More sharing options...
