Question

right now i have 2 pioneer subs 400 watts rms each sub and 1000 watts max each sub.right now i have the kenwood KAC-7202 amp rated at 460 watts rms bridged. should i get the MTX 6500d amp. and if so will it run both subs or just one and will it blow my subs

Answer 1

If your subs are single voice coil (4ohm) then I would go with the MTX amp. You could wire the two subs in parallel to get a 2 ohm load. The MTX amp is rated at 775 x 1 rms at 2ohm (probably closer to 850rms), and will work great with the subs, just keep the boost on the amp down. The Kenwood amp isnt a good match with these subs.

Now if you have dual voice coil (4ohm per coil), then keep your Kenwood amp. Wire each sub in series and then parallel them down to the amp (this is a 4 ohm load), bridge the amp and you should get 460 rms x 1 (probably closer to 500). Just be careful because the subs will be under powered and at high volumes more succeptable to blowing due to distortion. The MTX amp would also work on this but would be a waste of money because with a 4 ohm load it will give you about the same power as the Kenwood.

Answer 2

That amp is way under powered.

Any time your going to wire two subs to a bridged amp, you must add up the RMS watts of both subs. Since they are 400 watts RMS, you'll need a 800 watt RMS X 1 @ 2 ohms amp. Wiring the subs in parallel.

Answer 3

i would use 1 amp for 1 sub i would have 2 amps that are 2 channal that have a out put bridged of 400rms,if you find one that has that rateing get 2 of them and put one amp persub.
