So in the next month i will be starting a new box build. I am kind of good at this stuff but always look for others advice. So the new build will be for 2 Fi sp4 18" fully loaded subs. 1 Crescendo Audio bc5500d and 3 xs power xp3000 batts. Still have to find some one that makes an upgraded alt for my car(2004 Hyundai Elantra gt HB) that does not cost an arm and a leg. I will be removing the back seat building a large box and then walling around it the box size is going to be 48"w x 36"h x 30"d. Will be 1.5in thick with at 2.5in front plate. From what i came up with(been a while since i made a box) was a box that will have 15.98 cuft after porting. The port is 7in tall and 18.5in deep with a 7.5in drop should be tuned around 32hz give or take a little(if any one wants to double check fill free) Should be a fun build looking to see what other people think about it.

So i am starting a new build soon over my old Sundown audio sa8 v 1.75s (4 of them). So i am looking for some peoples input on my new system. The subs i am looking to change out for are 1. One Sundown audio z-4 18 $609.00 2. One SSA Zcon 18 $542.00 3. One SSA evil 18 $799.00 4. Four Sundown audio Sa-8's v.2 $740.00 5. Two Sundown audio X-15's $778.00 Just wondering what everyone thinks. Three of them are single 18's, so wondering if that is better then the 2 15's and the 4 8's. The car is a 2004 hyundai elantra gt HB ( my old build log) http://www.soundsolutionsaudio.com/forum/topic/52732-hyundai-elantra-hb/page-6?hl=holykaos Still have a few issues with the car, like trying to find a high output alt. Dc is the only one i have found and $700 is a little too much for me so i think i am going to remove my ac pump(Ac went out at the start of the summer) and make a bracket for a 300am alt. from mec-man and just have 2( the factory one for the car and a larger one for the batts). Not sure how to work the 2 Alts. like that but i can figure it out. Let me know what you guys think. Re: Added prices from ssa store.

So i have come down to getting 1. One Sundown audio z-4 18 $609.00 2. One SSA Zcon 18 $542.00 one of those going to remove the back seats build the box as port forward and sub up and seal all the way around it making the back seat area my batt rack and amp rack to keep the weight centered.

Would take some modding to add air ride to our cars but i have found a kit for them made for our car but its like 2500 bucks. Think i am going to swap out for some stronger truck springs and a better set of gas shocks. Just because the amount of weight i will be adding to the rear of the car.

How well did the back end of your car handle the weight of the sub/box/bat amps and what not. Thinking i might need to find some larger springs or swap some from another vehicle to make the rear hold the weight.

As for the car breaking it is the last thing i care about it has 170k miles on it and just gets driven to my work(replaced it with fr-s for daily) the rear end of my car has so much foam in it that it should help with the bulb breaking and like i said removing the back seat is no problem they never get used any ways. Oh and my rear windshield wiper is gone any ways friends broke it off being dumb. And the car kind of does need to be destroyed been threw a lot with that car bought it brand new off the lot and had so many problems with it that all i want to use it for now is an audio car but finding parts for it is kind of hard.

So i just started my build this weekend(tue-wed)for me. The build is simple, not to much to it. 2 Sundown Audio SA-8's Dual 4 ohm 1 hifonics brutus 1200.1 1 xs power d1200 batt. That's all the new stuff i am getting. I already have 1 d1200 under the hood and a 300amp custom built alt. This is going to go with my 2 sets of massive audio rk6 component's and my massive audio 4 channel with a pioneer touch screen dvd3100.

The system gets really low, I was surprised at how low it hits with no troubles at all. And if any one asks i have a reinforced windshield because of all the rocks on the roads around here so its about 1/4 to 1/2 in thicker and coated for impacts from anything that might chip it. (we put it to the test and a buddy threw a 5/8 in socket at it thank god it held up)

Crappy video with my phone( i hate the cam on it). Here's a little flex with about 800 watts way underpowered.

Fyi my AC is already out in my car, it died last summer and cost way to much to have fixed i can live with out ac i work out side all day long any ways. As to your question about the car Notorious that is up top and the 4 Sundown 8s would be swapping to the newer v2's they are a little better then the 4 v1's i have. I will choose my amp when i pick my sub set up and space is large enough that i can fit 1 18 in a large ported box or any of the other set ups. I have 4 8's in a 6 cube box now plus i can remove the back seats if need be. Nadcicle the largest alt. for our car was the 90 amp that my car has now so keeping that for the factory systems and adding a sec one just sounds like fun to tell you the truth. Oh forgot to add in the system i am aiming for is to break what ever i can in my car so i want it to get low.

My 8s doing a little work on a hifonics brz 1200.1 at 2 ohms

At last the other 2 subs are here and in, i will add pics when i take some and a vid. Had to rewire them because my cars electric system could not handle the .5 ohm load(yet). So all 4 are sitting at 2ohm for now.

Well the box is now all together and waiting for my subs. I missed the fedex guy today by like 20 mins to sign for my other 2 subs.

Been a little bit since i put an update up. I ordered my other 2 subs and they should be here today fedex says around 12ish. Once they get here all i have to do is cut out the sub holes, attach the bottom of the box, finish my little bit of bracing left and do all the wires to the box.

And a few more little things. Stripped my old system out. All the trim panels and all so now its just kind of hanging around until i drop the new system in. Got board and textured the ports just because i could.

Few updates really fast. Ports are now in and not going any where. This is what 2 of the 4 look like on top.

Lol no mold for the expanding foam but after 12 cans of big gap filler my hatch and all the open areas in the back of my car no longer make any noise.

Small update. Been working on a few things at once first the new box is starting to come together. I laid it out put the top and all sides on. Going to cut the holes for my 2 ports and the 4 subs some time today. how i made the ports. Any one take a guess what that is and where it went.

Ya its sketch up. Works really well takes some time to get used too but after you get the hang of it, its not too hard. Any ways i did a little bit more finished the Fat mat on the floors not much to see there and ran some up the pillars. Re-ran my Rca's and my remote turn on down the center of the car. Also found something i forgot i had in my car the pioneer I-pod control thing for the dvd 3100. So i pulled it out and freed up a little space in my dash. The run of rca's 2 pairs. Behind the scene look. The pioneer unit. And all the front trim is back in just have to put my seat's back in up front. I am leaving the rear seats out until my new box is built and in.

Been looking for some people in az but i live along ways away from most of the people i have seen on here. And all the shows and stuff take place near phoenix about 4 hours from me.

It does not seem like the old fat mat every one was talking about, there's no smell it sticks really well and rolled out very easy. Its also some heavy stuff out of the 4 rolls i have(each roll is 50sft) they weigh in around 25 pounds each.

Stuck down really good i was having issues pulling it back up to move it around a little when it was just laying on the floor. But we will see how it holds up.

So here's a new update on this system i have changed my mind a few times and went back and forth on what i wanted to do. So i am now doing 4 sa8 dual 4's in a new box i have been working on. There will be some plexi and a few other little things i plan on doing to it. As for an amp i believe i am going with the hifonics colossus. Going to wire each pair to 1 ohm and run them off both channels. On another note i spent the weekend doing a few things to the car. That's my 2 year old helping me roll out the fat mat. Next step will be picking up some truck bed liner and doing the out side of my roof and putting some cld tiles on the inside of it.

Ok so like always i can't make up my mind. I wanted the 4 in a row Top mounted box with the front facing center square port. But the box size would not look right with a small port. So in good old fashion i changed my mind and made a new build. Just looking for a little input on the box and if my math is right. The box is 22"deep 40"wide 19"high Its all 3/4 mdf (besides the cross in-between the subs that's 1/2 and acting as bracing) The port is 5"wide and 17.5"high and should be around 61.25" long if i did that right. Here's the box and what it should look like. This is a bottom view so you can see the sub cut-outs and such. This is what i used to tune and all that good stuff.

So made a design for 4 Sundown audio sa-8 Dual4. I need to figure out the port tuning for the box. Here's a work up of it i made. Its all 3/4 mdf with a double top plate to flush mount the subs. Box size is 39w 12d 16h(16 3/4 with top plate) The port size i was thinking was 6h 8w 7 1/4d
