Well i got that JVC HU, it goes up to 34 or something when i turn it on 19 all the speakers start making cracking noise, including subwoofer. I know that this HU is piece of sh.... but what might it be ? Sometimes i can turn it up til 20 and its working fine.

So earlyer this summer my kicker 650.4 got a little hot and burnt up. I was a Electrical Engineering student for 2 years so I know a little about the specific components in an amp. I took it apart and saw that it was a piece I haven't worked with before and about 10 of the same one fried. This is a picture from ROE(the amp guts section). I had my friend take close ups that I'll try to post tomorrow but he is having problems with his camera so not sure. Hopefully one of you guys can tell me what these are and if i'd be able to replace them. They are the first 4 black pieces under the metal on top and bottom and maybe 3 on the next sets of 3. Thanks, Austin

I currently use a Lanzar Mxa252 2channel amp to run the dual 4ohm 15"l7 in a 1.5 cu ft. sealed enclosure. Looking for a amp to run the L7 1000rms@2ohm under $300 shipped, Soundstream Picasso PCX1500D for $287 on ebay or HIFONICS BRUTUS BXi1610D for $232 on ebay both are 1100@2ohm. Any other options would help.

k im loooking for the price on a 12k soundigital amp thanks

k i have 2 rockford power elite series 1000.1's they are strappable amps and im running 4 l5 15's dual 4 ohm so i wanna strap em first off how do i do it and what do i need currently i am they hooked up seperate thanks

i have a popping sound though my sub when i turn off my radio or when i change a track, turn it on mute it will do it when i step on the gas , i first had 2 w6( old school 12s) and a directed 600d amp it never did it when i had that set up, but when i put this one in it started doing it after i played it cupble of times, so what could be the reason.

im thinking of getting a audioque aq1200d to push a mtx 9510-44 what you guys think

so my friend traded some stuff and got a sealed 10" menphis sub and a jensin amp. before he traded it i had the guy install it in his car to mak sure everything worked, which it all did and sounded fine. so he traded and after running wires in my friends car and plugged everything in the power light turns on, but when tested with my DMM there is no output in the speaker terminals... here is a googled page i found on the amp... could the rca's be bad? im pretty sure they are wired right deck is an alpine CDE-102 need any other info just ask... im lost haha

I just hooked up a rf t40001bd amp in my car, the amp is ran by 3 stinger sp1000 batteries and a 250 amp alt. I played it for a good 40 minutes I than went out to listen to it again and pop the amp smoked and the fuse discolored (but never popped... not sure wat else Im scared to put another amp in... Any help would be appreciated

Well for some reason my power winodws and my interior lights are not working any more so im guessing its my battery because i was away for 4 weeks and i came back and it was dead but wahtever, so im assuming my battery is like shitty but i wanted to get a new battery anyways so if i get a new battery would this help me out in the future for my 2 bl 12's and sax 1500d amp? i plan on getting a optima red top oir should i get a yellow top? i just need a new battery in general not just one battery to power my amp im going to get this done within the next hour and hopefully they change the battery for me thanks also could i just use my old battery to power the amp ? or do i n…

hi, i am positive that it is my head-unit causing this (it is a alpine 9887) but i am trying to see what else it could be. ok for starters i have my gains set on the my sax100.4 At volume 27 is the max (out of 35 i think) and sometimes when i have the volume at only 15 the drivers mid range will get very notice able louder and i will use the balance and the left speaker is barely playing and the left is acting like it is receiving double the signal. now i have the sax 100.4 running active and i am only using the high on the 9887 to feed the sax100.4 channels 1 &2 and then using the output to feed 3 &4. So if it was the amp couldn't one side play fine and t…

Does the epicenter help increase you spl or does it just act like a bass boost where it will just cause the amp to clip. Would it be a good idea to buy one if I mainly use an ipod?

i have been shopping around for batteries diehard is actually made by the same company odyessey is made by the p1 is basically the same as the there 1500, but i was just wondering what the p2 would compare to and if anyone has used these

hey whats up i need help choosing an amp(s) for my setup, my electrical upgrades are big 3 1/0 gauge, 2 runs 1/0 gauge 1 pos 1 neg, 200 amp alt, optima yellow top front,die hard platinum p1 in back, k i have 4 dual 4 ohm subs kicker 15 15's, i need an amp decision i either want a saz-2000, i would have to run it at .5 ohms will my electrical handle that, and hit hard, or should i go with 2 saz-1000 and both amps would be wired down to 1 ohm, which setup would b louder and which would work the best

i got a saz-2000 watt amp going to 4 kicker l5 15's, my electrical upgrades are 1 optima yellow top battery 2 runs of 1/0 gauge total 1 pos 1 neg, big 3 upgraded to 1/0 gauge, 200 high out put alt, and 1 die hard platinum p1 in the back, i will be running the amp at 1 ohm, people have told me that i should have much voltage drops others tell me i will, what do u guys think, and i want to get a voltmeter just incase how dou you wire it in

Has anyone used Odyssey brand batteries in their setups, and if so, how do they compare to other brands as far as disharge and keeping voltage up?

I'm wondering the best thing I can do to help my situation. It's been ridiculously hot here in San Antonio this summer and my SAE-1200D just isn't taking the heat well at all. My Cadence TXA1000D never had a problem but I guess with the extra power this SAE has the heat is causing trouble. The amp gets VERY hot to the touch and after a while goes into protect. At first I thought I had a problem with the subs cause they would make a strange noise before shutting off but it cuts out even when my HU is paused so I don't think I have a subwoofer problem. Maybe mount something like 2 120mm fans on the bottom of the amp? How would I hook those up? Just wire them to the power/gr…

I have been looking at getting the AP3000.1D, but I saw I can get the AQX3500.1 for about the same price, has anybody tested them to see if they do rated?

I am putting in 3 external batteries in the back of my suv. The batteries are obviously going to be grounded to the chasis. I have been confused on whether it would be better to ground the amps to the chasis as well or if it would be better to run the ground to the batteries. The batteries are each going to have 2 runs of 1/0 to the chasis. Which is a better idea?

At work we have numerous rtas used to test the frequency responses of circuits. This is tested through an osciloscope input. My question is if I were to find a mic that had an osciloscope conenctor at the end of it would the rta work for what I want it to do?

i have a zapco 2x100 that goe into protect at almost full tile i looked at voltage drope and the lowest was 12.77 volts and it went into protect and i turn the vol down and it starts playing again the ground is good any input?

Are stepsom amps really the best amps? if not, are they really good and do they really put out the power they say for example, does the V 14K2D really put out 14000wrms @ 12 volts or not? Last thing, how much are these amps from the V 9K2D too the V 142KD? Heres a link just incase: http://www.stetsom.com.br/eng/Produtos.aspx (Go to amps and click on "DIGITAL")

http://www.crutchfield.com/S-KJi47TPlPGC/p_130AVHP410/Pioneer-AVH-P4100DVD.html obviously doesn't cost $400 through them but I found a few sites that sell it for $400-450

Why does everyone run 2 Kinetik Hc1800s instead of 1 HC3800? You get more power and its easier to set up and its the same price if not cheaper. Would this battery also be enough with the two amps and a 200A alternator?

Hi, I am selling my 4 channels Boston amp. I can make a good deal with it, and I don't use rear speakers no more ! I need a small (in size) 2 ch amp to power my Focal 165 KP. I need about 2 * 100 watts rms or even less, and my head unit is good enough, so I don't need lots of features on the amp. The problem is the budget : I want a really cheap amp! But I want a brand new one. The Sundown 125.2 would be good, and would match the sub amp (a saz1000), but I would like it cheaper. I saw a Cadence Xa 175.2 xenith series at Powermax electronics, it looks good ! There is an entry level Rockford the R 300-4 (I could bridge it) that seems good too.(Powermax electronics) One poi…
