Hey guy,

I got a pioneer DVC TS-W5102SPL champion series sub, and my massive 3000.1 smoked out on me....this is the second time and im not gonna pay 260 to get it repaired....again.

But i was gonna trade this broken amp to a guy with 2 powerbass 1000.1's amps. is powerbass any good? and can I run 2 amps at 1 ohm each to the sub to produce 2000rms?

I got 0 guage and a kinetic 1800 in the trunk, and a 200amp alternator. Now the first time i blew the massive was cuz i ran it at 1 ohm....and the amp couldnt take it. so when i got it...i put it at 4 ohm and it took less than 2 minutes of bass and the amp smoked out. Amp still turns on....

any advice?

Correct me if i am wrong but is that sub not 2ohm coils? How would you ever run an amp to one coil for a 1ohm load? You can run an amp per coil, but IMO it is best to use a strapable amp so there is easy gain matching.

1: No. Powerbass is craptastic. He's gonna pay the cash to get it repaired, have a far better amp, and laugh at you behind your back.

2: Yes, you can run one amp to each voice coil, and gain "matching" won't matter one iota.

I still think you might be better off repairing the Massive amp repaired, but when you get it back, RECHECK YOUR WIRING! I bet you are going below the amplifiers rating EVEN THOUGH the woofer's two voice coils paralleled are one ohm. That's a NET one ohm load, but we all know that the impedance can drop below that.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

And what, precisely, is "this"? I don't see what "this" is; exactly that you are showing in that PDF screenshot?

That he can, indeed, run one amp per voice coil, as has already been confirmed?

As long as the power handling of the woofer isn't exceeded, what's the difference? Really?

I know the answer, I am just asking to make YOU think about it. Seriously, what's the difference?

i feel like the voice coils will end up burning because the amps have to be puttin out exactly the same amount on the each voicecoil right?

i appreciate you guys telling me what it is.

No. A common misconception, you can even wire them out of phase completely, and as long as the power handling of the motor structure is not exceeded, you'll never have any issues.
