i looking to see if anyone has ran one of these. cant find any real world reviews about it. i guess my main question is if it does rated or more or under and reliable?

yea thats what all the online dealer reviews seem to be like, but you know how online reviews can be " 1 12in sub on 100 watt amp shattered my windshield" lol just cant find anyone on the forums talking about them at all.

Ivd got a BK1300.1D on my icon.... its a solid amp puts out more clean power then my AP1800.1d. ON a DMM it will hit the correct voltage for 1300 watts when setting gains. The black ice line as a whole is a great budget line. I ran a 210.2 on my tweets and a 340.4 on my sls 6.5 midbasses and both of those tossed out nice power.
Things to notE:
pots for crossovers and gain are not linear. set both by DMM and test tone. -3db point is volatage X.707. my 4 channel had different gain settings for each channel pair.

my set up i am working on now:

those three will be in my chevy cobalt with a Rubicon 2500.. Ill be doin a build log on DIYMA. The BK340 and the BK210 where in my truck.. my signature is now updated for my truck. You should definitly pick up the BK1800.1 if need that power, solid amps.

i have the 1300.1 as well on a gcon 10" and love the setup. still tweaking the amp(just have it set by ear....need to put my volt meter on it and set the gains) but overall i am very happy with the amp. i need to upgrade the electrical on my truck as well.
im in the hunt for a 340.4 or the next step up from that amp for my doors.... going the matching amp route as well.

cant beat the price on the ppi's either.

The amp has never been clamped so NO ONE should be saying it does rated and/ or cleanly.

I believe you are right. A true becnh test of this amp has not been accomplished. Anecdotally, my 1300.1, 340.4, and 210.2 all met the voltage requirements @ 14V for rated power per my fluke when setting gains. As well, The 1300.1 has more clean power output than my AP1800.1 ever did. My SSA Icon thanked me when I made the switch.
With that said, I would opine that those voltages are just as accurate as any joe schmo who "clamps" there amps volage based on subjective impedance numbers.

im going to be running a set of skar 6.5 comps up front and 6.5s coax in the rear running off the 4 channel. so you say get the 800.4?

since you've been mentioning setting your gains etc and getting the right voltage, how did you set them? just curious.

also the newer ppi amps(black ice) are based off the soundstream rubicon series from what i have heard.... could be wrong.

I'm not 100 percent positive, but I "think" I saw a clamp test on the 1800 on one of the forums. If I remember right it did just a hair more than rated.

redrider:
Using OHMS law: Volts=SQRT(Watts x Ohms). So for the 1300.1 - SQRT(1200)=34.6.... i set the gain to 34-35 at my preset volume (32 on my kenwood as my rear fill clips on anything higher) using a -3 DB sine wave @ 50HZ. I like -3 DB as it gives a decent amount of headroom and SQ while maintaining high volume levels.
Also You are right on the rubicon base for the black ice amps. Grizz Archer comfirmed this on DIYMA along time ago. That is why I am using a rubicon 2500 with my black ice amps. similar designs and same form factor.


OP:
OCS has a great price on the rub2500.1's.... headroom isnt a bad thing.

they have one left at 150 shipped on ebay. just bought one last week. about 20 inches long. perfect next to my rubicon 2500.

Precision Power BK800 4 (http://www.ebay.com/itm/321145637495?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)

Or pick up 520.4 and run your Skar set active...rear fill on head unit. PPI amps have bandpass crossovers for mids up to 4K

The black ice is twice as heavy as the vfl.. If not more. I got offered 300 for the black ice lastnite so i sold it. Neighbor kid did not want to wait over the weekend to have one shipped so he made an offer I could not refuse!!! Hahaha
You could get by with using a 200amp fuse.. I plan on getting a smaller 2 channel and prolly another 1800 to hang onto..

Got the fuse yesterday. All Hooked up last night in the pitch black. It seems something isn't right. Doesn't quite hit like I feel it should.

And no warranty seal I triple checked lol so not a problem man

Its wired to 1 at the amp. I think its all because I switched my set up all around. I have my sub and port aiming in the cabin and I got it shoved all the way forward in the backseat opening so its like a walled trunk.

I got one of these the other day. $183 down the toilet. The input sensitivity is backwards, meaning I set the potentiometer at about where 4v would be (0.2-6v range) to match my Alpine CDE-147BT and got little to no output. The only appreciable THUMP came when I'd plug in / unplug the remote gain control. Then I started messing around with the HU adjustments. Finally I stumbled across the phase reversing and it made the oomph a little more noticeable yet. I have 2 shallow Alpine subs I planned on putting in the box for this amp to drive, but currently theres two Kicker 10" CVT's that I planned on watching go 'POP' from this amp driving too hard. Nope. These 400RMS subs (wired in parallel for 2 ohm load) are eating the claimed 1100RMS this paperweight is throwing at them all day long. Not even that nice hot plastic smell of the voice coil getting hot. Nada. No way this amp is anywhere near rated power.

What is this 'subsonic xover' for right next to the low pass crossover for? It ranges from 10-50Hz. ?

Any insight is appreciated

Apparently a few changes have occurred in only a short amount of time with this series. They advertise acrylic covers but mine has a brushed aluminum painted black. I'd prefer metal over plastic anyway, not only for durability but heat dissipation as well. They cheapened things up with their terminal lugs tho, I've heard people that have allen screw fasteners on theirs but mine are just #2 (http://www.caraudio.com/forums/usertag.php?do=list&action=hash&hash=2) phillips.

For the sub sonic filter - I have it in a 1 ft^3 sealed box, so I guess theres really no difference where I put this setting (10-50Hz) as this enclosure is not really hitting any of those frequencies anyway. I guess this feature would only really apply in a bandpass enclosure where the lows are accentuated all the more?

If I can say any good things at all about this paperweight, they would be that a) it delivers it's severely overrated power without heating up at all. Mind you it was 20 degrees here today, but it stays cool even when run hard for long periods. b) it doesnt clip at all while delivering this modest power. c) well, I'm out of good things to say already.

If you want an inexpensive ~1000 watt mono sub amp stable at 1 ohm but whose 'features' or controls are lackluster and backwards at best, this passes muster.

If you want an inexpensive amp that performs at its claimed power, has all it's teeth, and controls properly marked and functioning, lean more towards urban Audio Works or Jensen.

Also no offense man but you sound like you have absolutely no idea what your doing with the settings if you dont even know what subsonic filters are and how the gain knob normally looks like YES its commonly called a gain knob not a pentiowhatever and THE GAIN KNOB IS NOT BACKWARDS! THATS HOW THE KNOB LOOKS LIKE ON 90% OF THE AMPS ON THE MARKET LOOK LIKE. ALSO just because your head unit pre out voltage is 4 doesnt mean you put the gain knob on 4v...

Try this, for the Head unit, have the sub level max, bass boost 0, Low pass filter 80, Equalization flat, loudness off
amp settings: subsonic filter off, Low pass filter close to 80, bass boost off, 0 degrees for phase setting if your subs are normally set or 180 degrees if your subs are inverted. MOST important thing is to learn how to properly set your gains with -6 db 50 hz test tone and a digital multi-meter. Do a quick google search on this method. DO THINGS RIGHT before making these Ignorant claims.

Hell if you dont have a multi meter, you can even set it by ear. the gain knob is from left = minimum input voltage to right = maximum voltage. Turn your head unit volume to a level where you normally listen to with the mids and highs then slowy turn the knob from left to right till you get the amount of bass desired dont go past 70% of the way.
