ever since ive had my 96 standard cab, ive wanted to do a hidden system. then it was for more room, now its cause it would be cool. my buddy has 2 slim rockford p3s i sold him a couple months ago but up for sale. i would like to remove my seats and mount them in the floor. hide the amp under the rear seat, and run the wire under the carpet. it would be super clean and prolly be pretty cool. ive had a couple ideas of how to build the boxes, but keep going back 2 the same idea. have two sealed boxes with the face slightly bigger than the back portion. cut hole in floor the size of the back half and simply drop into place. add some grilles for protection and paint boxes in rhino lining. it seems pretty simple to me but was wondering if any1 had any ideas or suggestions to make it better. hell, with a 60/40 i can three under there...anyway, hit me up with some feedback.

Aaaah!
The mighty KAC-9104D! That amplifier is absolutely magic. (It must be magic, because it defies the laws of physics) 1800watts of power, yet fused at 60amps...
V x A x E = W
Volts x Amps x Efficiency = Wattage
12.5v x 60a x 65%e = 487.5w (This is the MAX rating)

LOL I have to agree with this. Single 12" Eclipse sub in a sealed 2 cube box and a MTX Thunder 251D (250x1). Plenty loud enough to attract unwanted attention. Plenty happy with the setup minus the not so stealthy side of the system. I'll be redoing my audio sub bass starting this weekend though.

i know i have ALOT to learn.....but what else does a reg. joe have to go by other than the owners manual or advertised wattage......at least im tryin to learn.....i might not be as smart as some people, but my shit works and sounds decent when i get done.....i hope to soon learn about SQ and enclosure design, since i now have room for more than a truck box.....if yall blowin minds with less than 500watts, then please school me!!!! :waiting:

He's talkin about blowin minds with less than 500 watts and to school him on how to do so.
It's all in the kind of sub you have and the type of box your using. If you use a sub thats highly efficient 92db s/n ratio with the right sized box (ported is my preferance) you can be really loud with that.
92 db s/n ratio is how loud the sub is with 1 watt @ 1 foot distance. So for 1 watt the sub produces 92 decible of sound at 12 inches away.
My Kicker CVR 10 is about 86 ot 87 db sensitive, every sub is different and usually takes a higher end sub to get into the 90db range.

i gues what im after is just a better understanding of how the box effects the subs. ive heard that a ported box is louder, a sealed box sounds better, and etc. basic, generic answers. id like someone to explain to me how the box effects the sound and how to determine what the box size should be....as proven by my "magical" amp, i cant simply go by manufactures advertised specs. i just want to be able to make informed decisions about my purchases before i waste the money. i need to know what kind and how big of a box i need, so that i can then decide on the subs,and finally a new amp....im sellin the kenwood
Wow... Just wow! There's proof that you can't always trust the advice that you get on the internet.

So I forgot which it was with the 1watt @ 1meter, but, where else am i wrong at???? :waiting:

volume = power....power = alot of suspension, and a stiff one at that....stiff suspension = low db/w.
s/n is signal to noise ratio and has all kinds of applications....from amplifier output to various converters to fiber optics....speakers are not one of them.

so the "sensitivity" rating that was refered to earlier, was the SPL, correct? the higher that number, the more sound that sub makes with a given amount of power??? also, whats db/w mean? i know how to hook the shit up, but dont know what the abr. mean? what should i be looking at when i buy my new amp/sub combo, other than the wattage/airspace ratings??
