Will this amp be enough power to run my 2 subs?

Question

I have 2 KICKER CVT10 CVT SHALLOW MOUNT SUB WOOFERS 2-OHM with 400 watts RMS and 800 watts max. i have 2 total of those and i was wondering if a 2008 SONY XM-1S CAR CLASS-D MONO SUB AMPLIFIER 900W would be enough power....by the way im putting it in a 2008 f150 so

there is not much room which is why i got that amp.

these are the specs on the amp

Mono subwoofer car amplifier

Slim series

290 watts RMS x 1 at 4 ohms

500 watts RMS x 1 at 2 ohms

Variable bass boost

Class D amplifier design

Switchable subsonic filter

Preamp inputs and outputs

Low pass crossover

Speaker level inputs

MOSFET power supply and output stage

CEA-2006 compliant

Answer 1

Sony amps are not the greatest by all means.  They are mediocre in design and dependability, but it's probably too late for that.   The main problem that exists is that with the power split between the two subs, you barely have enough to meet the half power requirement.  

Half power requirement is simply as stated.  For any given speaker to perform, you should give it no less than half of its rated continuous.  If the Sony's power is true then you will be okay, but don't push it too hard or it will strain and send distortion to the subs eventually leading to failure.

As far as the subs go, I admire Kicker products, but have a problem with their shallow mount theory.   The point of shallow mount is to save space without losing output.  In order to take full advantage of that type of setup, it should also require less space to play in (ie a small box as well).

   The .8 ft^3 minimum for those is not that small at all when most 10" subs use that as standard.  Something that can go down to .33 ft^3 is much more impressive & useful in tight spaces.  Not bashing your gear, but compare it to this:

The power handling is more matched to that Sony amp, and the space requirement is far lesser and would be easily accomodated in a truck.  Would you consider taking the subs back and trying SQ 10's?  Might be worth your time....

Answer 2

My first instinct would be to tell you to look elsewhere. Not due to any brand reason.

The only real reason to look for another amp is because of the fact that your subs are 2 ohms, single voice coil. That forces you to wire them at either a 1 or 4 ohm final load. Unfortunately that amp isn't stable at one ohm. leaving you with a 4 ohm load.

That being said. Keep in mind that the wattage rating isn't a hard and fast figure to stick to. There is actually a very wide range of choices. If you were to power those subs at their rated wattage and keep the stock system up front. You would have a very unbalanced sound. Without the head room in the front a sub system will overpower the front stage.

Over all. That amp being of decent quality and being CEA rated will do a pretty good job of powering those subs.

If you're looking to max them out though. I would look for an amp that is rated at 700-800 watts at one ohm.

No.  Get the Kenwood Mono Amp.  Much better sound quality and hard hitting bass.
