How much are these guys going to run for? $$$

Thank you for response. I tryed that box sealed at 1.8cf but im not sure if because i have subs facing towards the front in a crewcab silverado. Maybe i needed to build a box with single cambers or i missed something. I was not able to get good bass. My other box is a 2.4 cf after port it came down to 2.0 so im short on space (forgot to calculate space for port) is sounding good. Subs sound like 10s or 12s and even hit lower tones better then most subs i owned. So im really happy with them. Im buildingy 3rd box right now at 2.9 cf after port it will be 2.4cf with proper area port and it should bang great. I am very happy with sundown and i was not upset at all. Im sorry if i sounded upset. It just that i wish the .28 cf would of worked iny truck as it says on website. I had 6 of them with a 2500 and no luck. I am not a great box builder and i wish there were more guildlines for the subs. For example .28 cf not so impact , .75cf sealed optimal or 1.25cf max bass for sealed box. Some instructions that come with subs like jl or kick have all that info on websites and not on forums. So all the info u need is in the box. For my 6 subs i did not get a instruction manual. Maybe for experienced senior installers its not needed but For general public we really need more guildlines. Thank you for response And Keep uo great work ! Sundown Audio for life

I made another box.. At 1.8cuft for 6 of these and been messing with freq and subsonic filter and it sound really bad. Like subs are choking. No low frequencies or no impact bass. Just distortion. Im really getting tired. I never had subs that where so box dependent. Im not sure why sundown lists them as .28cuft if they dont perform at that. Im other forums i seen people using sealed box with 1cuft or .75 cuft each. I guess im going to try again with a port box. No luck with sealed. When you tired the system sealed did you lower the infrasonic filter, or play with the high and low pass? I haven't modeled the e8, but I have to believe they will work well in half the recommended volume. It would come down to what you want out of them, what you like sound-wise. I was under the assumption that you had used the available space with the 2.4 c.f. enclosure, is this not the case? If you can maintain the 2.4c.f. a 3" x 8" x 17" port will give you ~36 hertz tuning. If you shrink to 2.1 c.f. , the same port will tune to ~39 hertz. Let us know how it works out.

Here is the video of the box and set up. Elecrical is terrible. I never had an amp like the 2500 that sucks up all my power.

Here is the video of the subs. They sounding loud. Im at 2.1cuft @ 39 hz. I need to re make box and adjust for port so im at 2.4 cuft again. Thanks http://www.youtube.com/watch?v=OKiS1z1LxM8&feature=youtube_gdata_player

I made the port 3x8x17. I think im still short on size for 4 e8 8's put it sounds way better. It plays most songs very well. This shows me that my calculations was very off. So i will start making new box tomorrow 2.4cf and add the extra space needed for port displacement. Thanks for all your help guys!!!

Thanks for all your help! I tryed to seal box and it sound bad. I guess 2.4 cf for 4 e8s is too much. I just never had some subs that gave me so much trouble. I will try to make a square port 8x3x17 tune higher at 38hz see if that makes a difference. But im going to only have about 2.1 cf ( subs need .6cf) I played with setting when box was sealed and still no strong bass. If this port dont work im going to have to make another box and add extra space for port. Has anybody had any luck with different setting? Or u have to only use .6 for these e8 v2?

no, i been using http://www.mobileinformationlabs.com/HowTo-1Woofer-Box-CAL%20Port%20lenth%201.htm

Thanks for input. My box is a single chanber. So can i just add more ports? Or what is the recoomended? Currently is round 4 and 14 long. What round port can i add to tune the box properly. Thanks guys im really goint. To fix it today! A 6" port should do it for four of them. You may also want to raise tuning to 35 or so... in-vehicle tuned to 30 is often too low after loading on the vehicle. I go to a online port calculator and type my box size 2.5 cf and enter the 6 in round port and its giving me =for that 6 inch the lenght will be 21.53. does that sound about right? tune at 35hz. I ran into trouble, the box hight is 6 inches. SO i cant use round port. I firgure that out after going to store and purchasing. So the space I have to play with is 4 inches wide and 10 inches long. can I make a square port? how long do I have to make it? to tune to 36hz

I have a wedge side box. It goes under the back seat of silverado crew cab 2010. Can i make a port for a wedge box?

Im currently only using 4 of the e8's with that 2.4 ported box. Not all 6 of the subs

That was the measurment i got from a online calculator. Where can i determine what size port lenght for those aero ports? Where can i buy them? I only have round pvc in my town. Can i use 2 6" pvc ports? Do i put them in same side since they in a single chamber box? Or 1 on each side ?
