so im in class right now, and i cant focus cuz im so pissed off. all i have is a brutus 2608 on a Fi BL. running @ 2 ohms (rated 1700 rms). so heres what happened. im on my way to class, which is about a 20 minute drive. the music was on the whole time. probably going half tilt for the 1st half, then going hard for the last 10 mins. i have never encountered any problems with the amp in the past, so im very conused why it decided to shit out. im running a stock alt and battery, which i know is not enough for this amp, but thats what it is. i never properly set my gain, ive always just turned it down when i saw voltage drop or heard any clipping. back to the story, …

So i am in the process of a full rebuild and part of the rebuild consist of new batteries. I have all xs power batteries, a d5100r and a xp3000. What would be a decent charger i could have on them? Also what kind of on-board maintainer charger would be good to use?

I want to use a JL Audio XD400/4 amplifier to drive my front stage two-way component set. This amplifier is four channel but is bridgeable. I have a two channel input signal for the XD400/4. If I read the manual correctly, I need a y-adapter (I will just make a RCA cable with 2 in 4 out) to connect to the XD400/4 to use the amplifier as a L+R bridged. Right? So basically the XD400/4 needs a four channel input to run as stereo bridged? From the XD400/4 manual: "When a pair of the XD400/4’s channels are operating in bridged mode, the output will be in mono (only one channel). This mono channel can contain right channel only information, left channel only information or the …

alright so theres a problem that bothers the hell out of me I want an amp I am stuck between the sundown saz-1500d and the audioque aq2200d. the audioque does 2200 at 14.4v Im aware that that it would be almost impossible for me to keep that voltage .SO my main question is which one to get does anyone know what the audioque will put out at like 12.5 to 13 volts thanks for the help guys.

hey guys im in the market for xover, whats everyones opinion on this $150 epicenter? i remember in my old system i had one i just cant remember if it was this model..but i loved it..

What are you guys' opinions on these amps. Just want some feedback on it. Thanks!

Someone is selling it for $400. I wanted to know what is anyones experience or info in regards to this amp. I was not able to find anythingthrough google or yahoo.

Not washed, waxed, or detailed Before Everything plastic that has to come out (doesn't have to but gives you working room) Naked Can you see the difference? 2 bolts later All buttoned up Now for the bad news, when I opened the box up, a little black plastic tab fell out, but I didn't think anything of it. After getting it all in there, I fired up the truck and no voltage showed up. I put the stocker back in there and opened up the black plastic cover on the new one and discovered the stators all bent up from shipping. Whatta bummer!!!! I called up Nate, told him the deal, the new one went back to him today for sameday turn around when he gets it. He w…

If this specific question has been covered, or if this is posted in the wrong place, I apologize. I have not seen it yet on my research. I purchased an armdso nano O-Scope at a good deal, and figured I could maybe use it to tune my amp finally. I know the dmm method of tuning, but I figured why not try it with my oscope. The only thing is, my knowledge is non existent with electronics ironically. How would you tune it with a 1 probe x1-x10 with an alligator ground clip? I assume the probe just goes in the positive part of the amp to tune it, and the alligator goes on a ground source? The one I purchased does not have a 3.5mm jack with the black and red probes. It is a sin…

hey guys i have a couple questions regarding my mids/highs amplifier. i have a kicker zx 350.4 its the 06zx 350.4 model , this one http://www.sonicelectronix.com/item_6748_Kicker-ZX350.4.html#tabs i bought it used for $100. it was in excellent condition. only had it for a little over a month. this amp was a beast! my mids and highs were very loud when i first had this hooked up!! but now, my mids and highs seemed to have gotten quieter... my bass is still loud. to check, i unplugged my bass amp so i can just hear my mids and highs and experimented. id have to get to volume 45 on my headunit to make it sound like it did when it was at volume 28 when i first had the am…

how are they any good type by them?

Hello! This is my first post here. Crossing my fingers that I'm not breaking any forum rules. I have a 12 inch GCON ordered and the wait is killing me already. I've already purchased an amp and box for this sub and I'd like to have any willing opinions on my choices. The amp: http://www.sonicelectronix.com/item_43132_Hifonics-GLX1800.1D.html The enclosure: http://www.sonicelectronix.com/item_19279_Belva-Sub-Box-1SV12B-Belva.html A few questions: How did I do? Will this pound like crazy? How much impact will my smaller than suggest enclosure have on the sound? Ported good?How should I wire this beast-sub to this amp? (I'm thinking just running it at 650w @ 4ohms t…

I recently installed another amp and some 6x9's in my car along with my existing sub amplifier, I have some obnoxious engine noise going on now that wasn't there or noticable before the install. My power wire and RCA's are ran on seperate sides of the car, The amps do have a common chassis ground in the trunk. Is the engine noise because of the shared ground? If you need anyother info please let me know. Thanks for the help.

I just noticed that Treo is selling amps these days, looks they picked them up damn near a year ago too. Has anyone used or seen these at all, it looks like a nice amp and I'm sure it peforms equally as well. Does anyone know if they're using someone elses boards in them? I bet they only cost 2 arms and half a leg.

I got a directed d2400 amp hooked up to a JL 13w7. Theres a red and a green light that are both on. The red light has always been on as far as i can remember. The amp keeps blowing fuses like crazy. I can listen to music like half way or so and its fine but when i bang it it will just shut off and pop a fuse. I got 4g wire. I'm not sure why it keeps blowing fuses. I've been through like 7 fuses in a few days. I drive an 01 pt cruiser with no capacitor. Any help will be appreciated, thanks. Side note: it did the same thing when i first hooked it up but it worked fine for a few months now its messed up again. Also my serpentine belt is going bad an it squeeks REAL loud wh…

i want to have a test bench that i can test subs and amps and speakers on maybe even one that i can test how many true rms watts an amps is i have an extra head unit and some speakers i can hook up and a couple amps that need testing i just dont want to pull out my system to test them. how would i go about setting up a test bench? what do i need to set it up if someone has one can you take a video of it and show how you hooked yours up? please and thank you

I’m considering changing the amp for my FI q 12. may sound picky, however, the fan is kind of annoying. Even when I had it mounted all the way in the back of the old Jeep, it was noticeable. I am planning on mounting the amp for the q under the driver or passenger seat in this build and would like some input. I’m sure it will cost a little more. Not sure how much I can get out of the Taramps, or if a trade of some sort is possible somewhere. Seems to have plenty of power though.

i have a audiobahn A2200HCT i had it pushin a dd3515 at 2 ohms half the power and one day i got in my car and turned the key over with out starting the car and the volume was on 7 as soon as the bass hit the amp popped 4 times all the lights work and the cooling fans it just dont make no noise ive takin it all apart and looked it over i cant find anything burnt up nothing smells funny i dont know what it is. i have some pics but i dont know how to post them on here thanks for your time

ok well i dont know if this is exactly where im supposed to put this topic, so correct me if i'm wrong. I'm looking to start making some stuff for my dorm room next year, and i was wondering, what some good brands of amplifiers that are out today in the home audio spectrum. i mean power amplifiers, for subs and such, and also some other good 4-8 channel amplifiers for speakers. I assume i can just use a home theater receiver for the speakers and such, but as for the power amplifiers, im lost thus far. What are some brands that you all like, that y'all recommend. ive been looking at some Crown, but i dont know. My dad has meridian, but thats out of my price range for s…

aight i see that AP came out with a new amp the Ap AQX3500.1 anyone have any reliable info on it? does it actually do rated... i have heard good things about the ap3000.1 just curious if would be a good investment if i decided to upgrade my system?

Hey guys, just wondering if anyone hear has any experience with critical mass amps. I know they are crazy money but that isnt my concern. I just want to know if they can throw out decent power. I had picked up the v2 series pretty cheap and have not used them yet. I didnt want them, but my buddy needed money for his house. Any input good or bad would be nice. I have put a side the money for a sundown 1500d for the summer, but in the mean time i was thinking of swaping my pdx 1000-1 for the critical mass v2 sub amp. Should I do it? (the v2 are the smaller black ones)

I have a chance to pick up a Ultra Linear UL1500X for $50 bucks and was wondering if it was a good amp and price? It would be used to replace my Earthquake PH120.2. to run 2 Earthquake dbx10 10 subs. Here are the specs: 1500W Class X Mono Block Amplifier 12-17V Power Input 0.2-8V RCA Input Voltage Frequency Response 10 Hz - 350 Hz Short / Overload / Thermal Protection Bridgeable with second Class X amplifier 24dB Variable Subsonic Filter 24dB Variable Low Pass Filter 0-18dB Variable Bass Boost Remote Gain Control Module RCA Line Output RMS Power @ 14.4V DC 1 x 500W @ 4 Ohm 1 x 750W @ 2 Ohm 1 x 1000W @ 1 Ohm RMS Power @ 17V DC 1 x 750W @ 4 Ohm 1 x 1000W @ 2 Ohm 1 x 1500W @…

What was your favorite amplifier you have ever owned, and why was it your favorite? Just a fun topic that involves some retrospect. I was listening to my system, just taking it in today on the way home from work. I had to do too much thinking about my favorite comp set ever and still haven't really nailed down my fave, my favorite sub was simple, but the amp took a little thought. I had to weigh out a few, but the top few were definitely easy to recall. So give it up... The favorite you ever owned and why.

ok so i have a bazooka 500wrms mono im running until i get my saz-1500 fixed.... its running a fosgate power hx2 at 1ohm. its a damn good amp for the brand. i dont know much about it but lately since i got a h/u instead of my mp3 player it goes into protect when the bass hits real low note like on bass i love you for example the real low note when u get major excurssion it goes into protect. is it cause its not 1 ohm stable? gain is about 2/3 up frequency is all the way down bass boost is about 1/4 up sub level on pioneer 680mp is at about -10 thanx in advance

i just bought a crossfire vr-2000d that was apparently modded to handle high voltages and .5 ohm loads. well, today i hooked it up just to see if it worked, and to my dismay, it wasnt as loud turned up 2/3 of the way as my nine.1 was at 2/3. this amp should do more than twice the power of the nine.1 so im a little confused. it does play, bass sounds fine, its just not loud. i have both power supplies hooked up, a 1/0 gauge from my battery going back to a dist. block into 2 4 gauge wires, and just 2 4 gauges at the back grounding the power supplies. my electrical system is very solid, and both power supplies are getting 14.5 volts. the remote wires are both getting about 1…
