Amp/Sub Matching

[tCMetaLFReaK]

Looking at replacing the bazooka sub that came with my ride...

Kenwood Kenwood
Model KFC-XW1002DVC KFC-W3514DVC
Size 10 inches 12 inches
RMS Watt 250 380
Voice Coil Dual Dual
Condition New New
Peak Watts 1000 1500


My amp is multichannel and has a max wattage output of 1200.

I'm not good with electronics number (watts, ohms, etc.)

Well match the RMS watts on the amp to the sub or viceversa. If the subs is Dual voice coil, then make sure that you look for the numbers as a dual voice rms for the sub, then match the amp for it.

Right now, all I know is that the bazooka sub can't handle the power my amp is feeding it.

[dfwaltima]

give me your amp model and brand.

With that above i would wire in the coils at 4ohms, bridge the amp.

[dfwaltima]

Here is how to wire in the sub to draw 4ohms..

But which subs? They're both around 110 with shipping. I'm gonna pop it in the bazooka enclosure of my tC (maybe scrape off the "Bazooka" logo on the grill)

[dfwaltima]

the 10... the amp you have i dont see it been enough for the 12. besides 10's can pound pretty hard.

[tCMetaLFReaK]

good deal! Thanks for the help!

[dfwaltima]

anytime dude.

[Krdshrk]

10's definitely can hit hard.... You've heard mine, Matt.
