For christmas my parents are looking for some subs to get me. I have an 05 sedan and I know for sure im getting the pioneer AvH 5100 head unit. My dad was looking on Amazon and saw this amazing deal... .

So basically its two Kenwood Kfc 12"s (400RMS, 1200 Peak Watt) vs. 1 Alpine Type R 12" (500 Rms, 1500 Peak Watt) with the same amp.



Edit: Can the 1800 watt amp handle the two subs, and is the kenwood amp compatible with the Pioneer AVH 5100 head unit... help would be great thanks

 

The amp will work with the HU just fine, just about any amp will work with just about any hu, even a stock HU can work with amps with the correct adapter. Personally though, I'd buy higher quality stuff. The amp/sub aren't really very high quality stuff and 2 12's is going to take up a ton of space in your car.

I had a single JL audio 10w6v2 10" sub and a 500/1 amp in my coupe and it was louder than 2 10" fosgates and a 1000w fosgate amp, was louder than the 2 12's in my old concorde, and louder than the 2 10's in my neon. I'd go with a single high quality amp and sub to maximize your bass for the size it takes up. Hope this helped.

 

Ya thanks for the help pattyskin So Ive heard good reviews about the alpine type R 12" are you saying I should just get that and can you suggest a good amp? Thanks a lot

Edit: Which one do I get the 4OHM or the 2OHM?

 

i have the kenwood setup and i ****in love it:

 

right now you can get a kicker comp vx for $130 shipped at Amazon.com

you need to act now if you want it VERY limited supply

750 RMS, basically a L7..just round

great sub at a killer price

 

actually is $100 shipped

 

actually thanks guys but im going with an Alpine Type X

 

Generally speaking, the following will be true.
(Assuming speakers are identical)

A 12" Sub powered by 100Watts produced 90dB SPL (Sound Pressure Level)

Double the amplifier power, and the SPL increases by 3dB.

A 12" Sub powered by 200Watts produces 93dB SPL

Now, if you have (2) 12" Subs powered by 100Watts each, the SPL will also increase by 3dB.

So generally: (1) 12" Sub at 200Watts is equivalent to (2) 12" Subs at 100Watts each.
