Bass slammers bs212v ported for 2 12's kicker cvr

[Bass707]

hello! i am new to bass and i got 2 12'' kicker cvrs in a ported box. i am running them at 1 ohm on a hifonics brutus brz1200. im just wondering how to tune my amp.

the box specs are:
ported enclosure for two 12" subwoofers
5/8" medium-density fiberboard with gray carpet covering and 3/4" vinyl-covered baffle
nickel-plate binding post terminals
internal volume: 3.0 cubic feet (1.5 per chamber)
slot vent port (tuned at 33 Hz)
cutout size: 11-3/16"
dimensions: 33-1/4"W x 15-1/4"H x 16-1/4"D
vent is approximately 11-3/4" tall, 3-3/8" wide, and 12" long.

Do you have a stock electrical system?
Are the two cvr's 4 ohm or 2 ohm?

i use 4 awg wires and 12 awg Speaker wire.
4 ohm wired down to 1 ohm

what Car is it going into ?

What kind of Car do you have?

But to help with your original question:

Go easy on the gain right now, you haven't done the Big 3 so your lights probably dim a lot. Not to mention those subs don't last forever when you overpower them. Kicker wasn't joking when they said 400w rms. Right now you're giving (trying to) them 600w rms.

Don't turn the bass boost up at all, keep it below 25% if youre going to use it at all
Leave the phase at 0 degrees
subsonic filter should be at about 27hz
high pass filter should be at about 80 hz

thats a good starting point

Yup, you need some electrical upgrades. You have a tiny alternator. Keep bumping and you're going to kill your alternator or amplifier.

[dumpy]

i say down gain , to about 600 rms total till you atleast get the big 3 done, ssf and lpf , wat burk sa id

[Burkem_10]

Bass707, consult this thread (the third page and onward) if you want more information. I believe that the amp in that thread is a brz1200.1d

Look at the pics on the third page of how not to tune your amp lol!

[Bass707]

i have my level set at 2v, bass eq 0, phase at 0, ssf at 30, lpf 70

[Bass707]

thanks

Not bad. Are you sure your level isn't at .2v?

What CD player/head unit do you have?

[dumpy]

im scared by 2v you mean full ...

[Bass707]

dial goes from left to right. left 9 right 0.2. i set level at 2 not 0.2 lol.i got a pioneer deh-1300mp

[Burkem_10]

This is from the thread that I posted. Boosted puts it very well:

You subsonic filter might be too low depending on the tuning of your box and size of sub(s). Your bass EQ is set too high.

Try this, set the dials like a clock.:

"level" @ 12 O'clock

"phase" set that at zero

"bass EQ" @ 9 O'clock

"subsonic filter" @ 9 O'clock

"low pass" @ 12 O'clock

This is just a starting place. See how that sounds.

HOWEVER, I believe that your civic has a 70 amp alternator which is no where near enough to run that amp at 1 ohm where it will be trying to put out 1200w rms.

How bad do your lights dim? Do you have a multimeter?

You need to get some more 4 gauge wire and do The Big 3.

Okay well your amp seems to be set up pretty well then. Not what I was expecting to be honest lol!

[Bass707]

the only light that dims is SOMETIMES the dash board lights. thats all, not the head lights
and yes i got a multi meter but dont know how to use it

[Bass707]

btw does the box i got for my subs suck? lol

No, for being a prefab box it isn't bad. You could have gotten way worse. It should be just fine for those subs.

[Bass707]

o ok lol.. yeah i just wanna tune my amp/subs perfect for the box. or at least try get the most but safest sound outta my subs/amps

Okay well grab your multimeter and turn the dial to DCV so that it will measure DC volts.

Get to your amp and put the positive lead of the of the multimeter where your power wire is going into your amp and the negative lead where the ground wire is going into your amp. Leave the power and ground wires in too, just stick the leads in with the wire so that you can get a reading on your multimeter.

Then, play some music where the bass hits hard and tell us the lowest number that you saw, and the number that it was normally at.

When the music isnt playing it should read around 14.xx volts. When the bass is playing loud anywhere from 12.xx - 14.xx volts is okay. If your voltage drops into the 10.6+ to 11s you're gonna need to beef up your electrical.
