Alright, i have an 88120DVC 4ohm+4ohm eclipse sub, it takes 1000w peak 500rms.
I have a kenwood kac-7201 amp, it puts out 230x2@2 ohms, 460x1@4 bridged

So, If i hooked them both up in series, i'd only get 230w or so to the sub, and if i just hooked them up parrellel, i'd put the amp into protection if it was bridged. and if i just straight hooked them up, i'd only give each channel 4 ohms.... and i need to give each channell 2 ohms to get full power right? so, i'd have to buy another sub/amp which i am not going to do. is there some sort of resistor or something i can put inline to make it 1/2 the impedence?

If not, i was planning on just connecting one voice coil, since the sub itself can handle the 500rms, i'd put 460 just to one coil bridged. I was just curious if people do this or if this would ruin my coil.

Having Problems? Heres my Three step solution to anything 2gnt related.
Step 1: Put down everything in your hands.
Step 2: Grab a lucky strike, Smoke it.
Step 3: Walk to the fridge, double fist some keystone ice, sit down in the shade, drink one beer, finish cigarette, drink other beer, roll a joint, smoke it, walk back to your problem, and in about 5 minutes the solution will come to you.

If still nothing, your trying to hard. Start over at step 1.

Don't run just one coil, wire it series and bridge it. Or you could run 1 coil on each channel, since you don't want to buy another sub/amp thats what I'd do.

yeah, but im only getting half the power. only 230w rms right?


Does someone want to trade me for the 88120.4??? or an equivelent amp.

Yeah, the easiest thing to do is run 8ohm mono. Thats all the power your gonna get with that set up.

But you would be getting that to each voice coil. So 230+230=460, and its not bridged, amp should be fine. Give it a try.

wait what?

If i hooked my subs up to my amp, one coil per channel, then i'd put a 4 ohm load on each channel. so each channel would put out like, 150rms to each coil. right?


And if i bridged the channels, and i hooked them up the same way, it would over heat or go into protect mode, because two 4 ohm coils makes a 2 ohm load on 1 bridged channel, and then bridging it cuts the load in half again. so it would be a 1 ohm load, causing it to fuck up.

But if i wired it in series, then bridged it, it would be an 8 ohm load, and briding would cut it in half making it a 4 ohm load. still, only giving half the power it could be.

So, technically, if i want to get 460wx1, i have to have a SVC 4 ohm sub bridged, or a dvc 8ohm and wire it parralle....

And if i wanted to do it 230x2@2ohms, i'd have to have a dvc 2ohm sub right???

With my subs i'll either be 8 ohms bridged(then cut in half) or 150wx2@4ohms

And is there a possibility to run it series-parallel? how would you do that to a dvc sub, or is it possible...

Have you tried running that amp 2ohm mono? I've sold alot of those and we did it quite a few times, it worked just fine. If its going into protect from overheating maybe you need bigger power wire. What size are you running?

1) no, dont run just one coil.
2) you are correct abou the power part..you will only get about half the rated power
3) doubling the power only raises the maximum possible SPL by 3db..hardly noticable to most people.
4) run the coils in series (total of 8ohms). if you run each coil off of a channel, you risk introducing non-linearities into the driver. running it in mono eliminates this.
5) you can try running it in 2ohm, but the amp overheat (as already stated). if so you can back down on the gain, but you would be at almost the same SPL output as if you ran it correctly in the first place.
6) upping the power wire does nothing for an overheating problem. well, unless the cable is overheating.

:shhh: i do cocaine :/shhh:

That aluminum cone will STOMP if its powered right and correct cubic foot box. I had 2, pushed 700 to both. WOW is all I have to say.... and ouch.


I'm workin on it.... one thing after a f@#$ing nother!

Well if his power wire is too small its gonna help out a bunch. I can tell you from experience that kenwood amp runs fine on 8G, but if you do 2Ohm mono with it, your gonna need to step it up to 4G. I've sold quite a few like I said and we did them both ways depending on the subs the customer bought. I'd say give it a try and see, if it shuts down oh well its not gonna work. Hey crazy you should hear my 2000w pioneer spl subs .

Those power ratings are for 14.4V too in case you didnt know. So the actual power will be less, maybe 25% less at 12V I think.

If you want to sell the amp let me know, it will actually work good for what I need it for.

the car battery is 12v, when the alternator kicks on its 14 I haven't hooked it up yet, i think its 8 ga power... maybe 4. i don't know.. prolly 8.
