donberto Posted September 27, 2017 Report Share Posted September 27, 2017 So I am orderi2 Dc Audio level 2 12 s today, dual fours and 1.2k to run them. Local shop is doing box and install. My question is they are saying I should go sealed because they are in extended cab behind me and I will here vent/port noise. I have never ran a sealed box, don't really listen to tons of rap, mostly older rap and rock. Just don't want a custom box built and not like the way it sounds.

reedal Posted September 27, 2017 Report Share Posted September 27, 2017 You won’t have port noise if the enclosure is designed with the appropriate amount of port area to keep port velocity down. If you provide dimensions for the space you have for the enclosure, I’m sure one of the designers here can help you design the right enclosure to meet your needs SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted September 27, 2017 Report Share Posted September 27, 2017 Sounds like the vent/port noise is a cop out to not want to design/build a proper ported box since sealed is easy and hard to mess up. There are plenty of people who have done custom underseat boxes in those that are ported and worked great. Generally have aero ports vented on the side and the subs forward on the face at an angle from the seat to the floor.

donberto Posted September 28, 2017 Author Report Share Posted September 28, 2017 I worked in a stereo shop in the 90s, alot has changed, have done all my own builds till this point. 2 more local shops I am going to visit this week. I figured I'd ask sound difference as I have never had a sealed in a vehicle Link to comment Share on other sites More sharing options...
06RTCharger Posted September 28, 2017 Report Share Posted September 28, 2017 If u really like the sound of a good ported box, you will likely tell the difference with the sealed sound and possibly not be impressed. Whether you like the sealed sound better or not is all dependant on urself. I agree with the previous mention of the shop taking the easy route. Port noise is gonna come from a poorly designed box for ur specific equipment. Link to comment Share on other sites More sharing options...
YukonXL04 Posted September 28, 2017 Report Share Posted September 28, 2017 What truck is this going in? Taking out the back seat or putting under it? 2 12s properly ported is hard to do under a ext cab seat. Hard to get the airspace 18 Sierra 6.2 Z71 : 3 F8L's, DD M2a @.67, 1.95@33 05 TL build log SOLD 04 YukonXL : jvc kw-v51bt , RE 6.5c, 4 jbl gt5 12s, Memphis pr1000.1 5.5 cu.ft. sealed Link to comment Share on other sites More sharing options...

With those subs, he would only need about 2 cubes after displacements (which is on the small side) which will work with having a 1200w amp on them and probably a 4" pvc port per sub venting out each side.

donberto Posted September 28, 2017 Author Report Share Posted September 28, 2017 Ford f350 diesel, I am taking out the big bench seat that sits behind me, having box built look like the seat is still there, grey carpet or bed liner. Id one dc 12 in my od work truck, built vented enclosure myself and had no port noise. Like I said I am going today to visit 2 other shops, with the way the floor is shaped under the seat and me working I just don't have time to build this box, and I am integrating it into the stock deck for now, these new trucks with all the back up cameras and sync integrated into the huge decks are hard to deal with.
