turn it up

Running four Dc audio 15 level subs off 4 sundown 1500 wired to 1 ohm.with four odessy 2250 and 210 amp altnators The problem i have is that the four subs come out a long way (not meant to do it in a funny style osaltion)When i get to about 152 db on music. I used to be able to bass race at 154.5 but now can't run that loud at all. I switched from running two crown bpx 2200.And made the box bigger to over 20 cubic's after displacment.it was 14 cubic foot after displacment. I am wondering is the problem cause the box is to big. box is tuned to 32 hz. Burps at 45hz and 155.1 with the 20 cubic foot and 154.6 with the 14cubic foot.

Thanks but unforutally i check my ohms two or three times a week to be sure and ohms are reading prefect on ddm and have took out subs to check wires. Where should i put the sub sonic filter on the amps for port for 32hz.i have it set a little up from the 10 hz around 25 hz on the amp around a 10 percent of a turn from the 10hz on the marked number on the amp am i righ in doing that

I am playing the same songs as i normally did.But its like the subs get a mind of there own and strat moving the own way.Be playing grand then suddenly start moving madly

I am running the 1500 on my level 4 meself and they love the power.And can handle more

Cool thanks so the problem could be the bigger box

no subs are prefect. its just when i get to certain volume the subs start to move out of control like not with the music.

yup its .3 louder on burp but is really down on the music playing. 2 db or that ya looks like the subs will get hurt as they say. Ya tuned to the same frequency. Its in a walled car.

How long is this offer for

Strapp them at 1 ohm loads of power voids warrenty doh. lol 1 amp 1 ohm so. The amps seem to give out fractly more spl strapped doh from my tests(at the same amp load of course)

It was 0.35 nominal, or 0.175 per amp. I don't recommend doing that Was this .175 per amp after rise say or started at .175

Does it mattter what ohms you are running the 1500 at for the 16volts

The re build to the finals at toys for big boys So i got a mad idea to rebuild the sound system again So here is a few pictures of what i got up to. So this was the old looking system 111111111111 A bit of tape stop the dust getting in the vents More harming So now i bet the s**t out of it time to strt rebuilding

Well done dude.Any more pictures of the install.

if i had the money i'd go for the 3500 at some stage. Ya level four D2's strapped at .5 for burps.Ohm per amp for music. 210 amp alt voltage at 14.7.No external regulator doh.

Just a quick couple now have a few of flex in the car hday22040.jpg

If any one has any tips to get a bit more from the system i would be moore than help to listen weather its point one of db or a db thanks Eugene

Some updates to the system new batterys and amps four pc2250 And four 1500 soundown audio from dave at direct ice. Brings us to 158.3db

What will i do.Ha ha. Deliver of these Going to put a few blue leds in when i get time As ya can see some of the finished pictures are before i poished it up a bit

Door card builds not quite done So i cut the hole to F**King big What will i do.Ha ha.

Any more work seen

OR you could buy another 3000 for more power

I did 152.2 with 2.2k and four 12inch jl aduio w3before And 155 with 4.4 k with four of these 15 lv4. So i'd say your score is every good

I am running 4 lvl4's with two jbl crowns 2200.1 so about 4400 rms roughly at 14.4 volts Doing 155 burp And music peak at 154.5 and bassrace at 153.5 16cubics tuned to 35.

The amps go into prtect modde when run at .25 is it. Running four of the 1500's at 1 ohm each.When i seen the .25 got me going cause could run mine at .5 strapped .25 each for burp's if worked
