paulgroce Posted August 3, 2011 Report Share Posted August 3, 2011 Alright I have been looking into getting a car audio system for awhile and its come down to the point where I am just picking which subwoofer would be best for my setup. Vehicle: 2002 mercury mountaineer Alternator: 250 amp excessive amperage Big 3 upgrade Battery in the back: KHC2000 Max box dimensions: 44width x 23height x 23 depth Amplifier: Massive audio N4 Wires: all power and ground wires are 0 gauge Goals: Chest pounding bass when I want to impress and tight accurate sound quality when I want to really hear every beat. My original goal was to create a spl setup but now I realize imma want a lot of SQ also. Any experienced audiophiles out there that can share some experience with either subwoofer and help me choose the best setup? I have talked to Thilo from TC sounds and he says that 2 15" axis can be wired down to 1 ohm so thats not a worry. But I do want 2 of either one I am getting so if its dc then imma get 2 18" dc lvl 4's with some upgrades, and if I get the TC sounds then imma get 2 15" Axis. Anyone help me out?

-Hobby- Posted August 3, 2011 Report Share Posted August 3, 2011 (edited) If that size for your box is as big as you can go then I would stick with 15's whether from TC or DC. Personally I wouldn't make any upgrades to the DC level 4's either. They are awesome subs right out of the box. Ascendant Audio Havoc's would be a good choice as well. If you going for a better sounding daily setup keep you port area around 12sq in per net cube. And your box volume around 8 cubic feet net for a pair of 15's. That N4 would be the perfect amount of power for 2 Level 4's. Edited August 3, 2011 by -Hobby- Quote Link to comment Share on other sites More sharing options...

I don't know very much about voice coils and spiders and such but wouldnt it be good to upgrade those or atleast get direct leads? lol sorry that I dont know much about what I am talking about.

For what your doing and the amount of power your running a stock Level 4 would be just fine. They sound awesome without and changes. Direct leads is more of a personal preference. Not necessary at all. Quote Link to comment Share on other sites More sharing options...

I was thinking I could fit them cuz the cutout diameter for the subs was only like 16 inches. What should I tune the box to?

I wouldnt recommend going below 5 cubes net per 18" sub. I did a quick look at the size available you posted and your around 9 cubes net after port.and sub displacement. Thats single baffled box with a 36hz tune. If you want to tune lower your going to have even less space. You cant include the port area in the available space. The space you need is the net volume. The area you have left after accounting for the port displacement, sub displacement and and any displacements for bracing, 45's or extra baffles. You could tune anywhere around 34hz and have a pretty good daily box. Edited August 3, 2011 by -Hobby- Quote Link to comment Share on other sites More sharing options...

So if I got the 15's then i could optimize the box more and it would probly sound better since they have the amount of room they would need?

-Hobby- Posted August 3, 2011 Report Share Posted August 3, 2011 So if I got the 15's then i could optimize the box more and it would probly sound better since they have the amount of room they would need? Yep. Subs in the right size box will preform better than subs in a box thats to small or to big. 9 cubes net for 2 18's is to small. Quote Link to comment Share on other sites More sharing options...

I want to make sure I have everything perfect before I buy them lol sorry. Whats the difference between tuning higher and lower? I want something to pound me in the chest and then some.
