Yeah I getcha, I didnt see the doors had those recessions so the boxes fit in there nicely eh

Gotta be careful when you get those subs moving that you dont let them excurt into the SEAT, looks tight....

Any vids of the subs workin?

Good job on this build dude, been watching it since the beginning. Almost done!!!

Was on my way back from another town today and booming ...

On the half way i got stopped by motobike police..

Opened the window for hem, and then he asked, do i know why he stopped me, i thought ffs, was a bit over the limit in 60 km zone... and i said no i dunno.

He replied to me:

I just HAD to see whats in your car making such a noise //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

So we had a friendly chat about 5-10 minutes and he let me go after a heavy bass promotion

Any vids of the subs workin?

Made couple vids as well yesterday about the sub movement and stuff //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yees, that one is tuned onto 33 hz //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

Will try more different ports soon //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Some good new and bad news ..

So made few tests today here

with 33hz box it peaked @ 46hz and 153.6db

40hz was 150.8

33hz was kind a 148.xx

cant remember all other freaquencys but 20hz was very poor, something 142 db .. but didnt test propably as im kind a afraid yet lol

So charged the batteries again and removed the port (33hz tuning), so before it peaked at 64hz, but today on 60hz (box itself should be tuned on to 60hz).... is that the midbass boxes and the front amp fitting solution droppes the peak, i dont know ... Same time the theres no drivers side door seal after the first tests, as my friend thought that if the seal is fooked he can remove it, so there 1/2 inch cap now instead of seal ... Have to get new one so, so maybe thats the reason ...

The most annoying thing here, the last amp seems to be fooked, tried to set the gains equal with multimeter and the last amp shows twice less voltage and cant be gained over 25V at the same time first amp gains a bit over 40V all that on half volume from HU

AND the second amp gets dam hot even without playing a music (volume on 0) while the radio is on and the first one is totally cold ...

So i got a bit fooked amplifier and that makes me sad ... //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

So maybe i found a fella who can fix it, well see ...

So the total peak was @ 60hz today and 154.5db ...

something i made isnt right ... or the second amp gets worse ...

So can we say this score is 1 sub score ?

 

[RookieMekanik 10+ year member]

Couple more tests today and ...

Swapped the RCA cables back like they were at the first stage and 155.34 db

So seems while im using the RCA output from the faulty amp the result gains by nearly 1.5 db ...

Next step, RCA splitters ... and of course amp repair ...

Made some Propper Dropper tests

20hz, 25hz, 33hz and 40 hz peak

So far:

very poor result on 20 hz --- 141.5db

much better on 25 hz ... 148.6db

33hz 149.8db

40hz 153.8

Couple pics, but these were not the highest but very close to the results i got //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

25hz

40hz

Also tried bassrace, but as i was alone, its almost impossible to get a proper score, as for the safety reasons i didnt take the laptop into the car //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

1 amp was always faulty, gives out twice less power than first one and overheats a LOT ... //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

So after 2 runs with 1 faulty amp and all this on 41hz ! ! ! track and box tuned onto 33hz //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Next 4 weeks will do nothing, after 12 april when the first sound off will be held here, will rebuild the whole box, subs will be fitted propably and then port made wider for SPL ...
