Anyone know if this amp will run 1ohm stable or not? I know the site says 2ohm but I'm wondering as I can get a good deal on one atm and need a new amp asap.

Lemme know!

Most likely not because it is 1 ohm stable per channel. The max power is given bridged which means the impedance would be twice the channel impedance so 2 ohms min in to a bridged configuration.

I've run my HK204 at 1ohm mono on the rear channels....the HK series is supposed to be stable that low, however I did notice a hefty current draw at that point.

Begs the question tho......if you have a 1ohm load to drive and it happens to be 2 2 ohm loads, get 2 of the amps and run 1 to each coil or driver......:smilie_da

Barring that, keep a close eye on the gains and check the amp for heat the first time you try it......:dunno:

Yeah, I don't feel like tryin to find a second similar amp. Be easier just to change the subs up so I have a 2ohm config. Maybe I'll give it a test run, it is my buddies amp so I'm sure I can try it for a day or 2.

If you try running his amp at 1 ohm when it isn't 1 ohm stable, you could fry the amp.

I realize that ^^ I can figure out if its safe or not haha

Lol. Install it when hes not there. If it frys, tell him it wouldn't work at all. :)

HAHA yea...too bad its currently installed in his car.

Figured out that it will work for me. Just different config. 2 12" Dual 4 subs, make 1 ohm final for ONE channel, well Imma run it 2ohm x 2 channels. 600rms /channel will work great.

awesome.

Yeah I thought so when I came to the realization that I could do that..lol.

There are purists around here who will debate the merits of wiring the coils in series and the drivers in parallel as a 4ohm mono load on that amp. I have never heard a difference, but there are a couple of advantages electrically....:smokin:

It must be an age thing tho....:dunno: ....having started doing car audio in an era when having 200 watts total for a car was a serious system, I have to shake my head at the fact that it is taken for granted that having 1.2Kw of bass in a car would be enough.....but not a crazy system....:laugh:

God I love my toys.....:cheeky4:

i once had the hk1397 which is the exact same as what you got. I use to run 3 18's off the one amp. the subs where wired down to around .90 ohms and the amp ran with no probs. No clipping or over heating. Great amp tho.

Really? Well maybe I'll give it a try yet. I'm tryin to set up a night I can meet up with my buddy to borrow the amp for a bit. I'll definitly try both setups.
