Question

The sub is a purchased JBL 200 watt max. The amp is a Kenwood KAC-7202 920 Watt. I need to hook up this sub to this amp. Is there a way to lower the wattage to the sub.

The 920watt is peek power. The bridged connection power is 460W at 4 ohms. There is only one sub.

Answer 1

Well the problem is a mismatch of power for one. You need to find what the RMS watts is of each device. If the amp is more than 50 watts RMS over the sub I wouldn't wire it up. The first time someone turns it up..SMOKE!

Adjusting the gain may not be enough to offset the differences in wattage.

OR you could just find an old power supply from a computer like 300 to 400 watts is pretty standard in a computer. But if you don't have a 12 volt power supply and you have an old computer or know someone that is getting rid of one, or go to a garage sale or criagslist you can find an old computer cheap. take the power supply and if you look at the wires that come out of it pretty basic they are labeled in small print you can use that to power the amp then just hook up your sub out on your receiver to the amp. Hook up your sub and adjust to movies you watch. It works but if your trying to hook up a 1000 watt mono that might be a little much for it. You can probably get enought bump out of a 250 or maybe a 500 watt amp and be ok with a power supply out of a pc unless you have monster 600 or 700 watt one. If you want to know more hit me up and I can give you some specs so you don't burn anything up.

Answer 3

Jbl makes pretty hardy subs. I doubt your amp is actually pushing 920 watts. Do you have one sub or two? I would say go for it. You can look on the side of your amp there should be a gain control this allows you to adjust your power coming out.

Answer 4

You can if you do it right. You should be able to turn the gain down on the amp so that it won't blow the subwoofer... but keep in mind that if you ever over power it, you have more than enough juice to fry the coil on that subwoofer. The advantages to what you are doing would be that the amp should never really get over worked and over heated since you would be operating it at something like 50% or less of it's total potential.

Answer 5

You can certainly hook it up. I wouldn't necessarily crank it.

Is that 920 watts peak, or continuous? For that matter, is the 200 watts peak or continuous?

Peak means for a second or so it can hit 200 watts. Continuous means it can stay that way for a long time. Usually there are two ratings, one the peak rating, the other the continuous rating.

To lower the wattage, just keep the volume lower.

Answer 6

if you meant on the amp you can turn the gain down on the amp. that's the only way i can think of without blowing the sub but if you have a dual core sub you will be fine. i don't think that kenwood can push to 920 anyway.

Answer 7

Yea, you can do it. Just be careful as to how you play your music. Don't turn it up if you hear the sub making funky noises. And set the gains on the amp correctly, by matching voltage.

Answer 8

Wow your talking about one sub don't even sweat it.

Answer 9

yes, and as soon as you hook it up turn the bass all the way up and blar the radio!!

Answer 10

whats the RMS values and i can tell you
