massive amps

Massive amps look OKAY - nice big coils and decent looking construction -

But the THD is a tad high and the amps are rated at 14.4v . . .

I dunno - why don't you link to the subs your considering and the subs you have now.  Maybe we can see if there is any appreciable difference - what do you want to accomplish by swapping subs?

Massive has the BEST warranty in the industry.

If you have ANY of their product (less the DMX ReConable sub) installed by a dealer, they will give you a 2 year NO QUESTIONS ASKED warranty!!!

Covers amps driven below rated impedance, blown coils, and EVERYTHING   no questions asked!!!!

You dont even deal with the dealer for warranties, you send in the warranty card and receipt, and if theres a problem, you mail the offending product to them. They will fix or replace the item!!!!

They have a new line of amplifiers coming (should be on the shelves already) D Block. Up to 12,000W is the biggest.

All of their power ratings are CEA certified, so there are no worries about overstated power ratings.

I love the tiny blade amplifiers, Check out their CW Series Subs, or the new SQX 15.

You'll be impressed.

I was, and I became a dealer!

CEA ratings are 14.4v ratings from a 120v/AC power supply - so its a totally overstated power rating for an actively playing amplifer that would demand the amount of amperage those amplifiers will.  For a realistic wattage output at the 12~12.5 volts a car's charging system is going to show an actively playing car stereo amplifer, and you can take 20% off those numbers.

From the link below:

"Using 14.4 volts, watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise"

Anyway - CEA 2006 ratings just aren't all that impressive - 1% THD is in line with run-of-the-mill amplifiers across the market and up at 4-ohms- comfortable operating range for an amp - this THD is even less impressive.

I mean - I'm glad there's a market standard that has been developed, and certainly amplifiers tha meet this standard are perfectly acceptable for the majority of car stereo consumers - but I usually try to be a bit more discerning with amplifiers.  I'm sure some around here would agree with me.

Not trying to be too hard on Massive - it looks like good gear for the money.  I like the look of the amplifiers and certainly they'd be a decent starting point for a quality system.
