My pg rsd65cs review as promised

What kenwood amp does your friend have debo? Maybe it isn't doin rated wattage. Also, what amp are you going to have runnin?

My buddy has the KAC-7203, and I ordered the KAC-9103D.

His is rated at 500x1 wRMS@4ohm, but I had the gains set VERY low because the sub excursion was scaring me. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I just don't like beating the hell out of them when they are brand new, that's all...

Mine is rated at 900w RMS @ 2ohm, which is how I'll have them wired, so 450 a piece... If the Kenwood's put out what they're rated at.

Here's some crutchfield links to his and my amps. (and no, I didn't buy it from there... lol)

They are fused at 60 amps.. At 14.4v 60 amps would be 864 watts with 100 efficiency. At the 80% efficiency that good class d's can reach you are actually gettin roughly 700 watts seems kinda odd considering it is CEA 2006 rated, maybe their 2 ohm rating isn't cea rated but their 4 ohm rating is...

Edit:

Or maybe it will do more and you will have to upgrade the fuses. The Audison LRX5.1K is fused at 100 amps and can pull a hell of a lot more and requires a fuse upgrade when running its lower rated impedance load on all channels. Specs are so ungoverned even with CEA and everything there is no way to tell til you play with the amp.

Vids as promised.

Here is a link to my old 11kv.2's i had three of them in 1.98 cubes shared airspace. link

And now with the rsd 12's 1.4 cubes each one link

two link

These will be goin on roe also.

Aint it purdy

your box looks nice!

 

[skydeaner 10+ year member]

thank ya sir

thank ya sir

Are those cones ACTUALLY aluminum? Or are they spun aluminum fabric like the RSD65cs's? Just curious...

 

[tcguy85 10+ year member]

i think they are the same material as the comp set.i may be wrong though.

Kidwolf: the cone on the Dayton you ordered is 100% aluminum though. it's a sexy black anodized aluminum.

i think the OP needs a better camera BTW. the sound was all screwy.

Ya know, my buddies KAC-7203 blows fuses very often when hooked up to another buddy's Konaki 12". I also tried my 2 RSD's bridged on his amp yesterday, and it blew the fuses in 5 seconds. How do I know what I can safely fuse it to without the risk of harming anything, or is it just a guessing game?

An update on my amp: I received it from UPS Monday... Opened it up, the box was the original Kenwood box marked 9103D. Cracked her open and there lies a KAC-7203. I was HEATED!!!! I called up the company I bought it off of, and they said they were sorry for the inconvenience, but that it was how they received it from Kenwood. Long story short, the correct amp should be here by Friday.

 

[skydeaner 10+ year member]

Kidwolf - The cones are thick plastic with the aluminum look just like the components.

Debo - The only way to tell would be with an oscope to make sure the amp wasn't clipping after putting a bigger fuse in and upping the power. Or shoot an email over to kenwood and see what they say. And you shoulda kept that 7203 for your rsd comps and forced them to send you the right amp anyway lol.

TC guy - sound is always screwy like that when loud bass is involved. It makes the microphone of almost any camera clip/distort. But it was just my digital camera taking videos anyways.

I wish everyone was allowed to change thread titles lol.

i have to no idea what the fu#k is goin on........ //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

well i don't know if the the comps are just weak as hell, the amp is bullshit or what. they are wired in phase, but the barley move ( the mid ) the only time i got some descent excursion ( and they got fairly loud) is when i put my EQ on 'superbass' ( i have a pioneer 6700). so i thought, maybe it is the deadening. i torn some off. the comps still sound the same. these things should be screamin with 200 watts a side . idk y everybody who drives around with a stock system, u could hear the words from the music loud and clear but from my car, u can't hear shit

CEA Compliance in ONLY for a 4 ohm load. What the amp does at 2, 1, or less ohm loads in not tested. Here's a quote from CEA:

On May 28, 2003, the Consumer Electronics Association published standard CEA-2006, "Testing & Measurement Methods for Mobile Audio Amplifiers." This "voluntary" standard advocates a uniform method for determining an amplifier's RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. This applies to both external amplifiers and the amplifiers within in-dash receivers.

very nice to know troy, thanks.

oh yeah and teh 12's sound like doodie up top. I have them crossed at around 70hz 12db and then again at 90hz 12db and will soon be smothering them with somethign from the 880prs i am getting. I am looking forward to it's 36db slope on the sub crossover for these puppies lol.

try the subs and comps both at 63hz/12 db, or maybe the subs at 50hz/12db and the comps at 63hz/12db. somewhere in that range. the subs will blend better with the fronts that way anyway. and the rsd comps can handle being crossed at 63hz/12db w/o a problem.

and once you get the 880 i think you'll find the 24db slopes to be plenty. i have everything crossed with 24db slopes with mine.
