5 kicker cvr 12's hifonics amp

[mal1980 10+ year member]

currently i have 3 12" cvr dual 4 ohm subs wired to a hifonics brutus 2000w amp at 2.6 ohms, it pushes them pretty hard with the gain turned up 2/3 of the way. i want to add 2 more subs to the setup dropping it to 1.6 ohms. looking for input on wether or not this amp will have sufficient power to push the 5 subs

Yes, they are 400rms each. Thats 2000 total. At 1.6 that amp should do about 1500. Each sub will get 300rms, that is sufficient for cvr's

gain turned up 2/3 of the way

before someone else says it, gain is not volume control

i know that, but i never try to turn gain up past that amount on an amp, the subs seem to be maxing out, i dont think they handle what they claim, my amp only draws 55 amps off the battery on peak hits, and at 14.4 volts thats just under 800 watts max for 3 subs that should handle 1200 watts rms

Yes they can. I was running 1000rms off a old fosgate amp to 2 of them and was pounding them full tilt daily and never had issues.

well im only giving them 800 or so peak and if i turn the gain up anymore and listen to them i hear the cones start to pop from over excursion

Sounds like a pop from clipping

^ Exactly..Hifonics amps seem to clip easily....Also, your subs could be bottoming out if your subsonic is set well below tuning

30 hz subsonic, and yeah clipping pretty much means that amp wont adequately push my 5 subs, lower ohms means more distortion, ill probably need to upgrade to a memphis amp or jl

buy one more, wire them all down to a total .5 ohm load , and after box rise/coil resistance you'll be around 1 ohm. its what i do

not how it works to calculate output. measure output voltage and output current from the amp, multiply together, and you get at least a close number to your true rms output

run 4 not 5 and turn the **** amp down

 

[mal1980 10+ year member]

how do i measure the rms output your way? i dont want 4 subs, i wanted to do 6 off 2 amps, but if i can do 5 on 1 amp than im cool with it, i have my amp turned down b4 it clips or distorts

negative, unless you dont mind paying more then you need to. Get an MBQ DSC 2000.1d, or a AQ2200

how much is typical box rise? i dont have the equipment to test it myself
