Will the kickers be a whole lot deeper than the kenwoods? Both are in same price range both take 400w rms. kenwood being svc 4 ohm kicker dvc 2 or 4. To be put in a ported box in a 04 duramax crew cab behind rear seat on a kicker kx800.2, box has 6" mounting depth. Kenwood said 6" but no I had to put the plastic ring cover it came with on the box then the sub on top the ring then screwed it in.
Actually I meant bass deep as in which sub will sound deeper, which is a best overall sub. Kenwood advertise its mounting depth as 6" on the box. At best buy a cvr (black one) and kenwood were place on the counter and the cvr was slightly higher. Kicker says the aluminized cvr is 6 5/16 And the black cvr is 6 1/4
The Kicker will deliver stronger bass, also has higher sensitivity so I guess louder and lower it is. But still mostly is the box so it's hard to say if it will make a meaningful difference in a small box.
Take a look at this one is 6-3/8" 400W RMS dual 4 ohm:
Net Volume (Vb) + port displacement + sub displacement = gross volume.
So two 12" on 1.76 cuft is hell tight, The sub on the link I left above would require 1.75 per sub, on top of that the box is tuned a little high, those subs will get loud but on that box maybe not that low.
Better than the kenwoods?, I guess yes, worth the upgrade?? I don't think so unless you will be happy with whatever improvement you can get.
Ok S.L.A.B. from the models I have seen damping will limit resonances of the box and it behaves like if the sub was in a bigger box regarding that resonance lump but will not extend frequency response in any way like a bigger box will do.
You can use damping in any box ported sealed or whatever, you can put as much as you want as long as no moving parts are stuffed.
Id say look for a sub that works on small enclosures but from what I have seen improvements are marginal.
JL Audio makes for some specific vehicles custom enclosures that are derivatives of 4th order and manage to give deeper bass.. very expensive though...
If improvements won't be a night/day difference then I'm wasting my time. The kenwoods are single 4 ohm not bridged so they're getting 200w x 2 @ 4 ohms. When the dual 4 cvr's arrive they'll be bridged and it'll be 800w x 2 @ 4 ohms, will that be a night/day difference than it is now with only 400w in that box?
Lol, I used to have 4 12's on 2 punch 500's then I went with 2 cvr 15's in a box built to specs in a dodge intrepid on a audiobahn 1800,the 15's blew the 12's out the water, that's serious daily sound imo I miss the 15's but to do that in a truck, you have to get rid of the backseat.
I would have one sub on the backseat and one under the backseat in 1.7 cubes or something each, that should give both the space they need. that way the kickers would reach their spec. With some work it would sound like a single 15. I guess try first with a single box.
Joe, I just found a .77 cu ft per chamber sealed box for under the seat downfire. Kicker min. rec sealed box volume is 1 cu ft. .77 is closer than .9 is to 1.76 for ported right? So would you say it will hit the lows better in the sealed than the ported since its closer to specs? Will that be a night/day difference?
Just lowpass to 60Hz and Highpass to 60hz the rest of your speakers, use as much polyfill as possible in the interior, do not stuff the ports or the space immediate behind them, place the new kickers. You are done. The poly will prevent the sound to get too boomy, then you can further improve with the EQ. Try avoiding the amplifier bass boost at first.
The best way would be to have 1 sub on the backseats box and one in a below backseats box so that both would have 1.7 or so cubes. but I guess that's overkill for now. You can always upgrade later.
Hey Joe, I'm back again. The cvr's in my current box sounds nice but I want more bass. I'm thinking of a 15 more of a solobaric L5 since I don't know of anything else that hits harder, I'm sure 1 15 would hit the deeper notes than 2 12's. I would build a box for it sealed to the max specs which is 6.0 cu ft can you enter that in the graph with the cvr 12's in my current box and compare it?
