Metered the demo car 😬

[djdilliodon!]

I don’t think most want to go through 11 pages on the original thread so I’ll do a new thread for this. Little refresh, taramps smart 5k, 3.75 cubic feet each 15” tuned to 31-32 hz. Subs at rest sit at 2 ohm so I know I ain’t seeing fully power. Car is at idle so voltage drops to 13.3 volts. Box was built outside the car and put in the back seat area, bolted down, and a top trim plate added to make it like a wall. Sides do have gaps about 4” wide so it’s not totally sealed off from the trunk. Subs and amp I was playing for over 2 hours before metering so things are running a bit hot (will meter again when everything is nice and cool). The result? 150.6 on the glass @ 40 hz. Did get a 150.7 letting everything sit for 20 min and doing it again but didn’t take a pic. Now I’m getting curious to see actual power the subs are seeing! I should of did the coils in D1 but ran out at the time as I was impatient . Wish I also made the box to 4.25 cubes per sub but would of required building the box inside the car and my old azz ain’t doing that . I’ll get a truck next when this beater is toast!

I'm no meter guy but I think that's impressive. Especially firing from the truck. Will this be at slamfest?

not competing with this one, I use this car purely to give people demos locally before building them subs. If I’m gonna compete I’m doing a truck and that’s next

That's all I'm going for. To give and receive demos

is it in Florida? I’d love to go but won’t have the time right now . By the way this number is with everything closed (windows, doors, and sunroof). I already know with stuff open it will be louder and if measured in the kick. I’m only interested in the glass measurements tho. I know I could squeeze more if I do a rebuild and lose a layer on the spider and use dual 1 ohm coils. The other option is use the bigger motors I have with Dual 1 ohm coils and some other tricks but I don’t wanna get crazy. I kept this build as cheap as possible so when it’s shown off it has more wow factor.

I guessed 53's @ 40 hz. on your other thread. Isn't there supposed to be a specific spot on the windshield for the meter? You might meter higher in that location. I think it's 12" from the a-pillar or something like that. 40 hz. is pretty good. Congratulations on the 50.

you hit the frequency right on the money! I believe it’s 12” from passenger A pillar 4” above the dash. Problem is the wire isn’t long enough . After the car sat over night I metered again with everything cooled down in 58 degree weather. Everything sealed up with meter on the glass and it pulled a 151.1 @ 40 hz. Ima gonna stuff blankets on the sides of the box next to do a quick temp seal off to the trunk and see if that gains anything.

Gettin Down right there!! Helll Ya! Liken it ✌

New best score 151.3 and while I was driving so voltage was at 13.9v. Then of course I couldn’t resist and did a burp with the meter in the kick, what a difference . When I got home I did a a steady 40hz to and measure the load off the amp and it’s a steady 3.3 ohms. I wonder what a smart 5k does at 3.3 ohms and 13.9v . My guess would be 3800-4000 watts. Anyone use the smd meter for wattage? Is the thing accurate?

New best! Everything nice and chilly since it’s 52 degrees out today, 151.6 @ 40hz on the glass. Did some illegal maneuvers measuring from the drivers side kick panel and lawd this car meters way better in the kick panel! Broke 154 . For ish and giggles I was gonna stick the meter in the port but it don’t reach, it’s like a foot short the wire it comes with .

Didn't your meter come with a rechargeable power pack?

nope, mine is the 160 db version, only the cig lighter thingy .

151 and change is OK for that power and cone area.
