rockFord_Expedition Posted November 9, 2013 Report Share Posted November 9, 2013 You guys an proper box who says there's a proper box ? If there was why isn't everyone loud? Who else is doing 156 from cargo area besides Meade an myself? How does Berger get a 160 out if 4-18s in a forth in a civics backseat ? Proper box? I don't think so .. Op do what u want 4-18 s can an will work just saying The manufacturers say there is a proper range of airspace needed for OPTIMAL performance. Are you saying that none of these manufacturers know what they're talking about?

AA98hoe Posted November 9, 2013 Report Share Posted November 9, 2013 I'm saying there is no proven box design recommended means recommended dc 18 a recommend 6-8 cubes if I remember right an after long testing work best in 5 cubes an Miguel's on my power bigger would be just sloppy for me ....

Fuzzy336 Posted November 10, 2013 Author Report Share Posted November 10, 2013 98 I apprecieate the input don't get me wrong, but sense I'm only going to be running like 5.5kw I want to make sure I do have enough airspace, you know? I'm doing this build on minimum wage while still paying my bills so I only got one shot at this money wise My Youtube Channel Trying to guess the SPL of a system with out a meter is like trying to guess how much air pressure is in a compressor tank just by letting some of the air out. ...Seems like 90 psi...
