My friend has a ported box that holds 2 12" subs, the subs are Kicker 03C12 or 03CVR12, I am pretty sure that I looked at them and they are the 03CVR12's.

Anyways, he is powering them with a Kenwood 800W(decieving) 2 channel amp, KAC-7201.

The subs specs are ,

Dual 2 or 4 -ohm voice coils for wiring flexibility

Power range: 50-400 watts RMS (200 watts RMS per coil)

Peak power handling 800 watt

Ported box volume: 1.75-2.25 cubic feet

The amp specs are as follows,

800 Watts max power

150 Watts x 2 max (4 ohms) RMS

460 Watts x 1 (4 ohms) RMS

I think his system could hit way harder than it does, I think it is wired up wierd or something. I was wondering how should I wire up this combination so that it will hit hard?

First you have to find out if the subs are DVC 2 ohm or DVC 4 ohm. Measure resistance across the terminals if you have to ( DC resistance will be a little less than the nominal impedance). Then make sure both subs are the same.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

yeah, find out for sure how many ohms each voice coil is. you will probably be better off only powering one of the subs with that amp and will still be underpowering it. i use the same amp to power 2 6" midranges. he should get another amp. the amp is overrated anyways. there is no way that the sub will hit very hard at all with that amp

What I found out about the subs was that Dual 2 or 4 -ohm voice coils for wiring flexibility. Also the Impedance is 4 ohms.

Well that sucks that he needs a new amp, and that I hate when they say the amp is 800W when really, well really I don't know why they state that.

Can someone explain to me why they state that the amp is 800W when really the amp is actually only able to push about 150W or whatever to each channel?

Also when you bridge, does that mean you are bridging both channels to 1 channel and pushing all the amps to 1 channel?
