You need more battery. Your alt has been working at 100% none stop

This may be a build log so no sense making multible threads. I am itching to do something different and go bigger. For those that dont know, I currently have a 15in Q on a SAZ1500v.2 in a box I designed and built that is a rear center console in my truck. It hammers the lows and the output is simply amazing for only one 15 here is my truck Here is the current full list Power and wiring Big 3 done and all 1/0 KNU OFC 2 Optima Red tops, gonna add a 3rd *Monster Cable... Slim battery terminals Stock alt (for now if it holds voltage up) *Tsunami main fuse holder up front and distribution fuse box for back. *Kicker ground block *KNU 10 gauge speaker wire for sub, 16 gauge for speakers RF rca's, etc Head Unit Alpine IVA-W200 NVE-N872A KCA-100BT Sub, box and amp *one 15in FI Q, cooling option and extra spider *3.65cu ported console box tuned to 29hz *Sundown SAZ 1500D v.2 Speakers and amp Rockford T-2652s Components up front Alpine Type R 5x7 rears Alpine PDX 4.150 (love this amp) Here is the current box 3.65 tuned at 29hz. Here is my current amp setup install and space to work with (maybe) Now here is what I am thinking so chime in with your suggestions as nothing is set in stone yet. Switching out the Q and buying a FI SP4 15 to go in my current box and either add another 1500v.2 or just buy a 3000d or something similar. I am not sure how much of an increase in output I will gain but the SP4 looks like it would work great with my current box and tuning. OR go big with alot of cone area. I have sorta been itching to take both rear seats out and doing two 18in SSD's in about 16 cu ft tuned to maybe 32 and running those both off of the 1500v.2. If down the road I want more output than that (I cant imagine so) I could just get a larger amp. I am not totally against other subs but I have been very impressed with my current FI so I dont hink I could go wrong there. Maybe some ICON 18's? If I do 18's I will add a second set of Components up front. Goals are low, loud, clear. Music is Rap and Rock

Port on pass side facing up right now. I will be aiming for the same type response on the next build with 3 of them just more of it. . The new build looks like would have 270in port tuned at 31. But until then I am very happy the way she is

Well got to do alittle more testing today. It has a flat response which I love! Today the truck did 149.7 at 35hz but did 149.4 at 30hz. I think if I had burped it at 30hz last weekend when it did a 150.4 I would have done a 150 at 30hz. This is all Meca style meter at the headrest. After hearing several vehicles over the last two weeks that meter higher than me just confirms that to the ear and the meter mean two different things. These Sp4's are just what I expected and sound amazing.

Looks good, the lows are where it's at. I noticed your numbers went from 151@31 to 154@50 at one point. I would much rather have the first set of numbers than even care what one does at 50hz but that's me. Great job. You and your buddy in the pics are both loud as piss

M5 would be my first choice for helping the OP. He doesnt need much info either and can hook this guy up with a hella hard hitting system. great advice!

Will sound so much better lowering the low pass to 80. I think at 100 that notes come through that shouldn't. Grab a good mid bass and you will have a much better overall sound. Good video

Welcome and good luck

Xmax is 33 on these 29 on Q's. I don't want a real narrow band. I have never used a modeling program, wouldn't know where to begin honestly.

Well, actually it ended up at 247.5 in of port. Being tuned low I think this would work well..... If I made the port 45 x 6 across top that would be 270in of port and would bring the tune up to 31....... Either way would work well probably.

Even if I did it now and ran the 5500 at .67 ohms until I could add another 5500 I think it would still be loud as hell. Well, my wife may shoot me if I bought another 5500 right now too. Lol The box could even be built outside the truck and put in when complete. All I would have to do is add a beauty panel when done. This would keep my same false floor, amp location and really not change much other than not being able to look out back window. The back doors and back window are taken a complete beating right now and the wall may actually help that?

Indiana Damn Senchez, could you be any more vague? I will google when and where exactly it is I guess. LOL On another note for fun I did some measurements and quick design and have the perfect space for 3 18's walled off. It would be 19 cubes tuned at 30 after all displacement with 228in of port. 3 subs across bottom port across top. May place my order soon.........

That's absurd!! Lol

Thanks guys!!! I may try to make the drive, where is it?

No subs, so I run em low I'm going to cross them at 100-150hz when I have subs The doors look amazing BTW

Very good and low!

Build looks good, as others said I would change your Lugs and get some cheap wire hammer crimpers and a sledge hammer, even if you had to shed alittle wire to get them in it will not have any current affect at all. Works like a champ. Also be careful on having the mids crossed so low. They even say from 80hz+ on the specs. A good loud sub 60 note may just smoke one. I have mine crossed at 80 but thats just me Great build and look forward to seeing your progress.

bhahahahaha SURE, its the someone else was using my account spill. ROFL

Awesome scores man! You should be very happy with a street box and only one 15. The 12's shocked me too. Very loud

Thank you, I am no different than anyone else really. In my head I think "what if" probably too much. And I really do like this enclosure, I have many many hours in it and if I did change it would be a curiosity thing mainly. Here is a final video showing my setup to complete this build log.

Thanks alot!!! I'm not sure if I want to spend the coin or not. If I do it may be a winter build, lol

This page has pics of my 2/0 and flexibilty for reference

I should have had you check out my 2/0 Coleman Royal last night. It's more flexible than my 1/0 Knu Kolossus and has a thicker jacket to boot. I can get 4/0 for 4.80 per foot. It is stage cable made for concerts and very very nice.

Where are you at in Georgia?

Yeah, got the Mechman 370amp adjustable alt in and its a beast. Voltage is not a issue any more, I could use more battery bank for demoing for long periods but..... Overall had a good time at that meet. My setup is not a SPL metering style setup as I never built it with a number in mind. Although I was very happy that it did a 150.4 at the headrest. Anytime you go to one of those things it makes you want to change shit up. But after talking to many people last night and getting feedback from my setup I think I will just enjoy it awhile. It was nice to meet Shizzon and also meeting Senchez's family. I will post up pics of my new alt and maybe through a new video out. Its alittle louder and when voltage is stable at 14.5 LOL
