@@srtdoff01 I'm kind of in the same boat, old schooler now 43 wanting to do a little something in my reg cab silverado. I have had a few 150+ term lab daily drivers back in the day. I have an older reg cab I did a center console in and it's down pretty good so guess I'm going to have to go that route on this truck to. I'm kinda of hesitant on skar bc I did 2 sundown x 12s in a blow through for a friend and we tried a SK3500 for all of 2 mins then the protect came on and wouldn't go off. So he decided to run 2 t1500 bdcps and it's gets down. I see great reviews on them so maybe we just got that one bad one idk.

Yeah you’ll hit a limit on the stock sound processing (assuming you have same generation as my truck) so I may suggest going for a little .. less .. to start. Max the box air space out for whatever subs you choose and size amp appropriately. Downfiring could be cool I haven’t had any experience with that setup before but always wanted to try

No doubt that it’s under rated .. signal processor is sub-par tho and it really shows at certain frequencies

@@srtdoff01 not sure yet. I have very limited space underneath the back seat so I'm guessing a custom fiberglass box will hive me the maximum air space needed as for the amp its an mtx rated for 1000 watts. Hopefully its not too much but just enough.

MIKE GARCIA sounds good. Good luck with it! I went the same route but built them myself from MDF to get max airspace without lifting seats or intruding on rear passengers legroom.

@@los2hot499 i build boxes and only had 2 at the time but the sound i was going for didnt allow me to put more than 2 ported dont get me wrong I know you can put 4 8s in a ported box but why when you can get about the same sound with 2. You can put 4 if the box is sealed but i like ported boxes. Also I know the cubic ft is limited under a seat without doing risers you can get close to 2.6 cubic ft with speaker and port displacement.

@@los2hot499 yes they are better than the evl series but I would look into doing 4 of the new SVR subs they made those really affordable and they will surprise the hell out of you. Also running 4 zvxs requires alot or rms watts. Sorry for the long replies I know how it is searching for the best sound and it could get expensive if you have someone else doing it.

You referenced 4 SVR, I would go with 2 Zvx8s if this sound just as good or ma-8, evl's. Also would be getting another mmats 6150 so should be enough power for either configuration 1k watts to 1 sub or 1k for 2. Im not sure which model would match better with amps. Also which speaker ohm should I get for 2 subs or 4 subs dual 2ohm or 4 ohm? I think we get 2 cube ft in f-150, I can do seat lift thing not sure if that's a big deal.

Lol.......damm bro.

Chris Schroeder I had two at first in basically the same setup. It sounded great musically, but I needed more for rock style music. The 4 sub setup really punches you in the gut with clean kick drum hits.

@@srtdoff01 Oh sure I get that - more is never wrong lol but unfortunately I would struggle to get 4 in my XLT because of the power inverter underneath the passenger side of the rear bench seat. I could maybe squeeze 3 in but I'll probably be looking more toward doing dual 8" subs downfiring or I may try to pop in 2x 10" shallow mount subs around 500-600W RMS and that should do the trick too since the greater surface area helps bring the SPL up and gives you more of that "gut punch". Your system is a really cool setup though.

Chris Schroeder I hear ya. My limited has the power inverter under the passenger side also, but it’s set back far enough to where it doesn’t interfere with a full length box. 2x shallow mount 10’s will certainly get the job done! Let me know if you need help or have questions when you get going,.

@Paul Revere hey man .. I feel your pain. My first attempt was identical to yours; 2 of these 8” on an rp-1200.1 in a sealed box (one big chamber shared by both subs) .. literally the subs would go FULL excursion and there would be barely any bass .. was disappointed. Then, I cut a 3” hole in each side of the box (against each rear passenger door) and secured an 18” long PVC tube from Lowe’s as my port and BOOM it woke up soooo much. Hit pretty hard considering what the simple setup was, but the ports were noisy and I will say generally sub par acoustical feedback. Then, I routed the openings on the box with a nice large radius on each one (where I had cut the ports ) and then stuffed the box with polyfil and the system was totally transformed! So my advice is to either A) add some polyfil and make your own ports or B) add some polyfil and order a couple of these Precision Port 3 Inch Flared Port Tube Kit www.amazon.com/dp/B0002ZPR4W/ref=cm_sw_r_cp_api_glt_fabc_Q98NBF5HPE5QS59QQT30

Hell yeah you’ll love it

Hey man - took a little extra time tuning. I have to keep the bass setting on the radio at zero. Seems like the sensitivity of the stock EQ is less pronounced when it thinks there’s no bass to defend against.

Austin Bowling hey .. honestly the mid range is lacking a lot, but I feel the tweeters at least brought back some highs. I can listen on volume 26ish with the subs at 50% gain with no distortion and it sounds fine ... the bass slams but it’s just the midrange that needs work. I have all the pieces parts to finish the rest of the system now (zen a2b, focal components, mid amp, etc) just haven’t done it yet. I believe you’ll be happy for a while with the sub upgrade and maybe some tweeters.

Hey, do you have stock electrical, for your system ?

🙃

Hey Manuel! I think your calculations are pretty close. Preceding this video, I actually started with only 2 VD-8 subs in the same size box on the 1200.1 amp, but it felt like the subs were stretching past their comfort zone regarding physical displacement. It was a nice setup (for a week haha) but I wanted more. I also really liked the look of 4x 8” so decided to switch it up. Considering the two setups, I believe the 4x feel louder and are definitely punchier than the 2x setup. I won’t disagree that the 4x setup is probably choking a little … I did stuff this current setup with a fair amount of polyfil which although muffled the overall output, it also really cleaned the response of the speakers up. If I were to do a 2x setup, I wouldn’t use the VD-8s … they don’t feel rugged when actually given proper air volume compared to the construction of something like the EVL.

​@@srtdoff01 Thank you for getting back to me. I see what you're saying and I'm thinking of maybe doing a 2x EVL-8 D2 build. I've been playing around with several box/volume/port calculators and I'm thinking 2 of these would be a happy medium between available space and power. The EVL-8s will probably want more than 1.5 but I think it can work with the SKV2-2500 and some poly-fil. I want to maximize that space and not go crazy with lift kits or nothing like that and definitely NOT looking to bust my windshield. On a different note, I am also planning on replacing all of the speakers with some TX65's and TX65c's. Did you replace yours and what did you do about the little center speaker in the dash?

@@mriosf I think you’ll be very happy with that setup! If I did it again I would maximize 2x EVLs instead of 4x VDs. I only replaced the tweeters and also removed the center stage speaker.

@@srtdoff01 Hey my man, I think you mentioned in another comment that you did the big 3. How many feet of cable did you end up using? I am spec'ing put my setup to get all the 1/0 gauge ofc I need. On that note, how long was your run from the battery to the amps in the back?

never too much bass!

Juan Eguia Jr. Juan Eguia Jr. the box in this video was tuned to roughly 40hz. I am now running a new box tuned to 38hz with 4” ports and yes it gets down low. I will say that the SKAR RP amp line (2000w and lower) doesn’t support well below 38hz. Ive tried the RP-1200.1 and RP-2000.1 and while they beat hard above 40, they miss hard below 38. I’m now running an SKV2-1500.1 and it is a night and day difference compared to the RP’s. The SKV2 is much cleaner sound and pounds these cheap 8’s down towards 30hz no problem. Don’t expect 4th order 15’s type of lows, but they definitely do the trick for me.

From the factory sub wires. Just cut the harness and spliced in new leads.

Los2 hot hey man sorry for the late reply ... I am not sure about clearance for other subs. I basically mapped out the minimum dimensions required for the sub mounting, figured out the angle that the sub needed to sit at and then built around those dimensions to stay within the stock seat mounting configuration. It’s not rocket science, just needs some patience and a couple good tools my bro.

123joker187 - hey bud. 1 ohm straight up works an amp and especially when played for long duration. I am running the 2000.1D @ 1 ohm now and after a few minutes with it cranked (behind the seats so no airflow) it gets crazy hot ... and that's with a sufficient alternator and all 0 gauge wire. An interesting thing to consider is the amount of power lost due to heat at 1 ohm vs the usable power at 2 ohm. You should try at 2 ohm for extended period of time and see what the difference in heat is. I feel that it makes more sense to "grow" your system (use larger amp but run at 2 ohm or 4 ohm) compared to trying to crank the shit out of a smaller amp. Just my 2 cents. I tuned my LC2i based off guidance from this video ... kzfaq.info/get/bejne/bqxkiNhq0b3Hdok.html ... I suggest to watch the whole video. Its very informative and provides a couple tuning options based on your specific setup.

Ruben Castillo hey man ... wired to 1 ohm at the amp. Scroll down to where it says “step 2” and look at “wiring option #1” www.instructables.com/id/How-to-get-the-most-BOOM-from-your-subwoofer-and-A/

srtdoff01 Thankyou for the response! I’m currently running a kicker 800.1 and my old kicker sub was 2 ohm..this is a small upgrade..mainly excited for the box. I’ve been impressed with skar products so figured I would try one of their amps..good day..👍🏼✌🏼

Billy Patterson Cool! Good luck with it and have fun!

srtdoff01 heck yes! I will and I’ll upload a video or two of it..subscribe to see..👍🏼

Brandon C I was worried about overpowering them. They are getting 300rms each now and are rated at 400rms. I tried looking around to see if anyone was pushing more than RMS to these subs and couldn’t find anything.

You are correct. For some reason I thought they were the 900rms ones. (Zvx) got the subs mixed up. Skar makes great products for their price pointe

Brandon C all good! I bet your setup is way loud. Haha as soon as you posted about the EVL I went and got the specs from SKAR and drew up a new box in SolidWorks to see if they’d fit without raising my seat. They will! 😬

i noticed you said you had 4 of the EVL 8in subs. Im looking at getting the same ones but wasn't sure which amp to get. What ohm's are you running your subs at? I was looking into purchasing the RP-3500.1 amp

It’s less than 1.0 per side (box is divided in two with two subs per side) I know it’s too small technically but I don’t really care 😂. When I do another build I’m going to do 2x 8’s but competition grade and give them more breathing room.

@@srtdoff01 Awesome...i did 4 SVR 8" and each sub gets .61 which is a bit to small....you cant really tell until you get the volume up pretty high then you can hear the box choking slightly. Much better option is to use 3 of them at .71 per sub tuned to 36 hz....this box is tuned to 36 hertz as well and really sounds very good. My truck is a 2015 GNC Sierra 1500 crew cab and the biggest i can get with a 2-1/2 seat lift is 2.92 cubes gross.....i actually prefer 6.5 subs in a truck they sound great. For reference im using a 1500 watt amp by audio control.

Most likely need a Line Out Converter (depending on what your factory trim level of your truck is and depending on if your stereo is OEM or aftermarket)

@@srtdoff01 forgot to mention the LC2i I’ve got. And the factory 8” in the platinum

Higher impedance filters out unnecessary noise better, which is almost completely unnecessary on sub bass as our ears aren't all that sensitive to those frequencies to begin with. It is far easier to create more power at lower impedance, therefore you often see larger amps stable to 1ohms. There really is no intrinsic "better" impedance. If the source is clean, and no over-level clipping is introduced by driving the gain too high, all a lower impedance means is more power. Typically, with your mids/highs, people stay above 2ohms and preferably above 4ohms. Music is dynamic, and you often only see the wired impedance on a certain frequency. As you move above and below that frequency impedance will rise due to many factors and you can see upwards of 100ohms of resistance.

Uh yeah @wickedwitt04 nailed it
