i've got a crossfire vr2000d thats supposedly been modded to be .5 ohm stable and handle high voltage. it has 2 hookups each for power, remote, and ground. these all need to be hooked up right? how can i test the amp beforehand to see if i can run it daily at 1 ohm? it should do around 2800x1 @ 1 ohm, and i'll be using 1800-2kw of that for my 12's, so it wont be running full tilt but about 2/3. anything else i need to know before firing up this beast?

I tried emailing powerbass on how to get some XA 3000D amps, I need to run 2 12" MT for street b. I was wondering, where I can possibly buy one from?

I just installed an avionixx 440.4 amp into my rsx and I am hearing 'static' distortion coming through all my speakers. The distortion, though slight, 'plays' along with each note of the song if that makes any sense to anyone. I was thinking of adding a noise suppressor but I am not sure if that would be another waste of money. I am begining to think perhaps the amp is a defect or just not up to snuff for the job (quality-wise). Here is what I have tried thus far: -Ensured secure ground to the vehicle chassis using 4 guage cable (same gauge as power line). -ran rca straight from the deck to the amp thus negating any possiblity the other rca's/speaker cables could be cau…

I have been looking around for some suggestion for electrical upgrade on a budget? I have been told to do a big three for voltage drops and light dimming but i am still getting some mixed reviews about that. I was wondering if running a second battery would help with light dimming and voltage drops. Im not really looking to spend more than around 2-300 at this time. Im running a zeus 3000 watt amp to 2 12 inch pioneers. Car is a 2002 honda accord dx.

will this amp run at 1 ohm daily? http://jbl.com/car/products/product_detail...ser=GTS&cat=AMP i want to get two of them and two brahma's, 1 amp on each brahma. since the brahma is dual 2 ohm, the amp needs to be 1 ohm stable right? will that jbl amp work? thanks for any replies.

has any body used this amp looking for info like clamped power and if it puts out more then rated

2 sets= 4 mids, 4 tweets, and 2 crossovers I was looking at the Alpine PDX 100.4, But i want other suggestions. BTW, the amp must be a minimum of 4x100watts. Thanks for the help! Joe

Hey guys, this is a question for Dave Edwards but I want everyone else to chime in too. I am considering going with an MTX 81000d or 1501 amp. The question at hand is, if i went with the MTX 81000d I'm gonna get a modded version. Since its modded would i have a higher chance of blowing the amp? Does anyone know anything about the 81000d? Now for the 1501amp... can u modd it to 1ohm? If I do.... what is the possiblity of me blowing that? Does anyone know the rating on the 1501 if u did drop it to 1ohms? And finally..... can the 81000d be runned daily? Has anyone had experiance with them? Help me out

This is the guts of the radio. capacitore blew on the right side this is the small fuse for the power wire constant... this picture is the wiring there are three wire one is power constant, ground and the third wire is one speakerwire(that runs in the dash) hahah only allowed one speaker nonsense. radio back in the dash. comments... will take pictures of the current set up soon.. should have did a build log

Ok. So I put the zcon's and the 2500d in. Now when I set the gain using the dd1 till I can get ahold of my friend with the oscope, the voltage goes down to 12.5. I have a mechman 270, big 3 in 0 gauge, ran the pos and neg from front to rear batt in 0 gauge, installed fuse in front, fuse in rear, soldered all connections. Rear batt is a diehard platinum 31m marine agm with 205 reserve, but yet when I turn volume up to around 30 out of 35, amp goes into protect mode and volts drop to 12.5. (Radio was o scoped at 40hz and 1k hz and had no clipping evident)Even at 1500 rpm. Am I missing something or is the saz2500d drawing that much amperage? Also speaker wire was 14 gauge. A…

Alright, read thru the pinned topic for this, seems easy enough..but im doing something wrong.. im usin an old school volt meter but it has "ACV 200 and ACV 500" .. i set it to ACV 200 (AC volts)..the amp is a Sundown SAZ1500D running at 1 ohm so... voltage = sqrt (1500 * 1) voltage = 38.72 ish.. can someone verify that please... so i pop in the 50hz test tone, loud off, bass boost off..volume to 3/4 and I stick the voltmeter to the outputs of the amp.. it tells me 2.8 and up to 5.something at full gain.. something is wrong just not sure what. appreciate any help.

Does anyone know if it is a true remote gain control or just a bass boost? Also if it is a true gain control, will the actual gain on the amp supersede the remote knob? By this I mean no matter how high I crank the remote knob, it will not go past the gain setting on the amp, correct?

Hey guy's. Just doing some research and was wondering if the deka was comparable in power to the xs? I can get the deka for 225 and the xs for 290. The price difference is great but is the quality and power there aswell? Thanks Matt Cusack

If I have one battery, is a good or bad idea to run the negative cable from the amp to the battery? Did the chasis have more resistance than, let say, 14ft of 4 gauge cable? I'm asking that because I read that grounding the amplifier at the battery minimize voltage drop, don't know if that is true.

UPS showed me some love yesterday before I headed into work. Refurbished and doesnt have a scratch on it. The only thing is it didnt have a birthsheet....so I may take it somewhere this week to get it benched. average birthseets range around 320rms x 2 @ 2ohm which is how I'll be running this on 4-4" Dayton midranges.

what type of fuse should i use for the amp to battery power wire (in an inline fuse holder from knuknoceptz). if this helps...the wire is 1/0 gauge, the amp is an saz 1500d, sub is going to be a bl15.

My 97 EB expedition has 4 gauge wire comming to and from the battery. Double that on the power. I am going to replace the ground wire on the bat with 1/0, but the power side is all so beefy I'm not really sure I need to. My deck has a volt meter built in, and I have been playing with it, and wanted to know if you guys think I may need to upgrade the electrical. I have not installed any amps yet and really just want to get a feel for if you think anything else should be upgraded. When idle I sit at about 13.8 V. I don't know how much drop I should expect, but if I open and close all 4 windows at the same time I drop a few tenths of a volt. When I turn on the lights …

I currently have the Big Three (actually the Big Two) in 4 gauge. I was wondering if it was worth the money and time to buy some 1/0 and redo it. I have an AQ1200d, stock battery, stock 145amp alternator Any input in welcomed.

Does anyone have an opinion/experience with these new Soundstream PCA100d or PCA1500d or PCA2000d? Will they hit their numbers? Are they worth 250-350? Thanks all

i got 2 RE HC 12s, i have em in a 6 cubed box tuned to 31 hz, wit a mtx 1501d powerin both. I think i hooked them up wrong or something, Cuz my rearview mirror dont even vibrate. and my friend can do that wit 500 watts. i used the wiring wizard at rockford fosgates site running it on 1/0 gauge wire http://www.rockfordfosgate.com/rftech/wiri...x=21&image.y=13. personally, i believe that i should have hooked each speaker to a different speaker output on my amp. Heres some pics ofwaht the outside of amp looks like. http://www.crutchfield.com/S-kNz22QCXzEr/c...&display=XL#Tab and, http://www.crutchfield.com/S-kNz22QCXzEr/c...&display=XL#Tab I dont no what phas…

Well i sent the piece of junk db electric alternator back and went for a dc. cant wait for it to show up ill be sure to get pictures and even a video. from everything i see it should be awesome cant wait.

Looking at buying one of these,but cant find any user reviews anywhere. Does anyone run hertz amps? This thing supposedly makes 2k at 2 ohm! Seems pretty badass!

k, well i went and got a dual 30amp fuse power dist. block. i got questions that need sum answers. 1.) how do u wire up a capaciator with the dist. block? 2) and i was wondering if i need a fuse block as well? since the power dist. block has dual fuses then i thought that i wouldn't need that. 3.)how do u wire up 2 rcas from the deck to 2 amps? the deck only has one set of rcs. but i have 2 y spliters layin around. how would i hook them up? thanks.

so i got an offer ona kinetic hc2400 for 200. sounds like a good deal to me.... but i heard if you plan on running a H.O. alternator it will kill the kinetic batteries. Is this true? I wont know if i even need an alt untill i get the battery installed.
