Will this combination of subs and amp be loud?

I am not looking for a ton of bass so that you cant hear anything but bass, but I want it to be fairly loud. With my previous set up I couldn't really hear the bass with my kicker 6 x 9s playing. I have 2 10in subs 8 ohm single voice-coil 150 RMS, 1 is an mtx terminator, and the other is a c10 kicker. This is the amp that I plan to buy:





Class D Monoblock Car Amplifier


RMS Power Rating:


4 ohms: 300 watts x 1 chan.


2 ohms: 500 watts x 1 chan.


Max power output: 1000 watts x 1 chan.


MOSFET power supply


LED power indicator


Tuned Bass EQ (0-18 dB bass boost at 40 Hz)


Speaker-level inputs with signal sensing for automatic turn-on)


Preamp RCA outputs


Short circuit, DC offset, overload, and thermal protection circuitry


Aluminum die cast heat sink


Built-in cooling fan


Gold-plated RCA level inputs


Gold-plated screw terminals


Variable low-pass filter (50-200 Hz, 24 dB/octave)


CEA-2006 compliant amplifier


Frequency response: 5-200 Hz


Dimensions: 11"L x 2-5/16"H x 9-3/8"D


8-gauge power and ground leads recommended. Contact us for information regarding a discount on a select amplifier kit when purchased together.


1-year Sonic Electronix warranty|||NO! It has to be 300watts RMS x1 at 4 ohms





this amps will be exactly perfect for your two subs!!

hope i helped! =]|||Just Googgled kicker c10 and this is what I came up with:


*10" Single voice coil


*8 ohm independence


*150 Watts RMS


*300 Watts max


*Sensitivity 87.3 db


*Sealed enclosure volume min.- 1.0- cubic foot Max volume 2.4 cubic foot


*Vented enclosure vol. 1.25 - 1.75 cubic feet





If your box is within those specs that speaker should be able to get to 112 db at its max limit of 300 watts. At 150 its 109db which would be just noticeably quieter. For most people that would be loud. Around 85db is normal conversation. I made some assumptions about the specs given in the speaker info, as most of them do the left out some critical info which could make a lot of difference but if you assume 1 watt / 1 meter for sensitivity my numbers should be good. That is also only going to work if your box is within the specs they list for that driver.





Here is OSHA's chart for what they consider safe:


TABLE G-16 - PERMISSIBLE NOISE EXPOSURES (1)


______________________________________鈥?br>

|


Duration per day, hours | Sound level dBA slow response


____________________________|_________鈥?br>

|


8...........................| 90


6...........................| 92


4...........................| 95


3...........................| 97


2...........................| 100


1 1/2 ......................| 102


1...........................| 105


1/2 ........................| 110


1/4 or less................| 115





So by that chart you should be able to do damage to your hearing fairly easily by listening for more than 1/2 hour per day. If you want to do that damage in 15 minutes you would need do hit that speaker with almost 600 watts which would likely burn it out.
