which amp

[93witemaro]

I wanted to know which one of these amps would you all recomend me to use with my two kicker cvr 12 4 ohm subs.I already have them both in my possession the amps are a kenwood kac -8151d , and a dubmag audio, my cousin sold it to me for 30 bucks its the dub8001 .I looked up the specs on both and the kenwood puts out 500 watts at 1 ohm and the dub says it puts out 800 watts at 4 ohms and it is not 2or1 ohm stable. Which should I use that will make the subs hit hard. Thank for all of your help!

Re: which amp

are the subs dvc ?

Re: which amp

yes they are dvc

Re: which amp

specs of both and the kenwood puts out 500 watts at 1 ohm and the dub says it puts out 800 watts at 4 ohms and it is not 2or1 ohm stable.

if kenwood is 500rms and the dub 800w max ... go with kenwood at 1ohm
if not go with dud runing it at 4ohm

Re: which amp

the dub is rated at 800 watts rms at 4 ohms, but do you think it really puts that out,I looked up the kenwood and was tested and put out 517 watts rms at 1 ohm

Re: which amp

the dub is rated at 800 watts rms at 4 ohms, but do you think it really puts that out

,

yes

I looked up the kenwood and was tested and put out 517 watts rms at 1 ohm

yea but it has low efficiency in 1-ohm operation at 66%
