Question about Kenwood KAC-9152D Car Audio Amplifier
I have tried running it at 4 ohms bridged and it runs fine but when i switched over my subs to 2 ohms per sub and ran them individually to each channel it cuts out.. it won't cut out however if i turn down my bass gains. i've added a cap , i've moved my ground countless times to better spots, i've replaced all my wiring to competition wiring, brand new battery i'm out of solutions. i originally had the problem with one sub. the answer i was givin was i had a bad coil so i bought a directed sx 12 and wired it up and still had the same problem so i bought another directed and ran them into a 4ohm series and never had a problem i'd like to go down to 2 ohm but is 4ohm my only option here.?

SOURCE: Amp goes into protection
First change the wire,and disconnect the subwoofers to check if the amplifier turn on without going in to protection mode,if the amplifier go to protection mode you gotta change the Audio amplifiers IC's because they are in short circuit.And if don't go in to protection put one speaker at a time to check if one of them are damaged.Good luck.

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

The best answer depends on your budget for the sub(s) and exactly what kind of sound you are looking to get. Your amps RMS output at 4 ohms is 200 watts and at 2 ohms, it's 400 watts. I could not find that it was 1 ohm stable.
If you are looking for the absolute best bang for your buck, I would highly recommend a pair of entry level MTX 10" subs, model 4501-04, currently priced by Crutchfield at $49.99. And if you buy a pair, they throw in a free Bass Slammer BS210S sealed enclosure. The MTX's power range is 112.5 to 225 watts each, right in there with your amps output. 2 of them in parallel give you a 2 ohm load, just right for your amps best power. And they sound great. You simply can't find a better deal for $100 bucks!
If you want a little better SQ, a pair of Rockford-Fosgate P1S410's should be considered. Again, going to Crutchfield, they currently have this one "BOGO" (buy one get one) for $99.99. You will have to provide your own box, though, no free one with these.
Finally, if you want the best SQ, and your budget allows, consider a set of Alpine SWR-1022D's for $179.99 each. These have dual 2 ohm voice coils, allowing you to series the coils and parallel the subs, resulting in a 2 ohm load to you amp just like the MTX's and RF's recommended above. You will probably want a somewhat larger enclosure for the Alpines as well as a fatter wallet. Your amp is right at the lower end for powering them, so they probably will not be as loud. But they will sound good.
One thing we haven't discussed is the box. The enclosure is just as important, perhaps even more important than the sub(s). More accurate bass is generally produced from a sealed enclosure. A ported enclosure will be louder, but at the expense of sound quality. And whether it's sealed or ported, the enclosure needs to have enough internal volume for the particular sub you are planning to use. A sealed box in the range of .75 to 1 cu/ft will be OK for any of the recommended subs. Add about 15-20% more volume for a ported box and keep in mind that the port needs to be specifically sized for the frequency for which it is tuned.
Hope this helps.

I guess this Amp is stable down to 2 ohms. 500 Watts X 1. Unfortunately there is no way possible for you to present a 2 ohm load to the output of this amplifier. Here are your options.
Speakers in series with VC in parallel = 4 ohm total Z
Speakers in parallel with VC in parallel = 1 ohm total Z (not good)
Speakers in parallel with VC in series = 4 ohm total Z ( Whats the point)
Speakers in series with VC in series = 16 ohm total Z ( Whats the Point)
So your best option to maximize power transfer from your amp to your speakers would be option 1. (Z = Impedance)
