Amplifiers / Head Units / Processors / Electrical

i got my hands on one.. it should be here in the morning.. i got it from a friend.. his dad has it in one of his old broken down trucks, (rednecks with lots of money) anyhow, his dads, brother did SPL back in the 90's and this is one of the amps he used... he knows im into spl so he asked what i would give for it... i know its a surf borad cheater amp fom years past, i knew them to be a pinkish purple but he says this one is silver, and about 4 feet long, he said the number on it is HC100 .... anyway. its in working cond, what kinda resale am i looking at on this?

i took my equipment out of my car to diagnose a problem. while it was out it was stolen. so now i am stuck with factory power. the problem now though is, the factory system had some issues when i bought it. at a little over half volume the sound from the tweeters cuts out when there is a louder sound.. like a yell or.. scream. or just louder singing. head unit? or amp. 03 z4 by the way

I currently have a 750 ca ac delco battery in my 2001 Buick lesabre. I'm going to be running my sundown sae 1200 @ 2 ohms for awhile and then may be adding a sub and dropping to one ohm. My car has a stock 130 amp alt. I have a kinetik hc1400 from my last system that is just sittin around and haven't gotten much interest when I tried selling it locally so figured might as well use it if it'll be better. First off can kinetiks be used as stand alone batteries? I don't want to run two batteries, so I'm wondering if the kinetik I have would be better then the ac delco battery in the car, like will it be noticably better?

A few hours ago I put a Sony Head unit in my friends car. Not sure what model; her parents took it out of their old car. Once it was wired up, we tested it. The tuner was coming in static-y or not at all, depending on how we moved the antenna wire around. It was a 2000 corolla and didn't require an antenna adapter. The cd function and aux function work fine and sounds clear. They listened to fm radio with the factory HU on the way here, with no problem. Any ideas?

So, i had my meter mounted on the left side of the pocket below the HU using velcro. well, that was late last year (cool weather), and now... Hot Weather = the glue/tape on the back of the Velcro melting. so, heres a few pics of my dash. there is nowhere to mount it that i can see. you can see where the trim piece around the pocket is a separate piecs. i have to take that off when i need to get to my HU. so i cant mount it there. ANY opinions wanted. thanks!

guys i need your help. i have a sundown sax-1200d powering 2 sa-12s. lately the amp has been making this high pitch noise as soon as i turn my car on, and after 20 minutes of playing it will go into protect mode and it gets pretty hot. is the amp screwed up or is it something else? any help would be greatly appreciated, thanks

Here is my problem. I know the out put values on the amp @ 2ohm(115wrms) and 4ohm(75wrms),what I don't know is the output @ 3ohm which is waht my comps are. Should I assume a midpoint? And effectivly gain down to say 85w(100wrms 3ways and 90wrms 2ways)meaning figure voltage for 85w @ 3ohms and set accordingly. Or do I just need to get an o-scope and do it on a bench?

I am looking to buy a head unit with a built in gps. I want a high end head unit and I am willing to spend around 500-1000. So any suggestions will be appreciated. It will be for a pontiac g6 gxp.

I'm looking at possibly running three 4 ohm subs, which would give me a 1.34 ohm load (of course, you all know this already ). How much power would I lose if using an amp that does its power at 1 ohm?

I recently bought some 35w 8000K hids from DDM Tuning. I installed them and now every time I turn my lows on manually, my HU (Kenwood KDC-MP345U) just stops playing music, forcing me to turn my HU off and then back on. The HU stays on but seems to just be frozen. If anyone knows how to fix this please help. Thanks in advance.

I have a pontiac g6 gxp and plan on getting a sundown 2500d and was wondering if I will need a alternator and or just batteries.

new job way more cash! ok so i have been planing a build with some skar 12s changed my mind to put 4 ia ported in my trailblazer. well i did the big 3 i can tell a diff, but thats on a single dr. right now im trying to get the power to put 4 of them. ill be getting 2 kinetik batts under the hood and then another big one in the back. i plan on putting about 1kw max to each sub, also getting a ho alt. kinetik has a charging system also would i need oreven want that? then my trunk space is wide not so long would i be better off walling with them or a sub up port back deal. im not really wanting spl or sq more of a mix of both. im waiting for crescendo comps to come back out …

heres my problem, i already have my amps in hand, in question is the mono subwoofer amp which is a hifinoics brutus BRZ2400.1D RMS Power @ 1 ohm 2400 watts x 1 channel i also already ordered my subs which are 3 fi q series 18's, someone brought up to me that with ohm rise i really will only see around 500 watts per sub, and to me thats a waste when thats only half there rated power..so i have 2 options to go from here, by another fi q and end up with 4 18's and buy another brz 2400 watt amp which would really put a strain on me budget wise, or stay with the 3 18's and use the brz 2400 watt amp on 2 of the fi q series and buy a Hifonics Brutus BRZ1200.1D for only $209 and …

im having major voltage drop and headlight dimming i have a rockford fosgate t1500-1bd and a power acoustik 1000max 4channel have stock battery and stock alt, all in a 2000 chevy silverado single cab 4.3L V6 also have big 3 done with kolussus fleks 1/0awg would a bigger battery help, like a kinetic HC2000, help or what should i do thank you

I installed a fi ssd lastnight. My enclosure is 2 cu ft tuned to 32 hz. At first I set the subsonic filter at about 12 o'clock and I wasn't impressed, the lows were really lacking. I figured since the filter ranges from 15-50 that half way would be 32.5. I turned the filter back to around 10 o'clock and the sub really opened up, I'm very happy with it now. I don't want to harm my new woofer so I'm just curious if I have it set correct. Other info. Hu is an alpine cda 105 (2 volt preouts). Amp gain set a hair over half way. No bass boost and I'd say the lpf is set around 10 o'clock also

You guys are gonna hate me for the next couple hrs but i want to go ahead and make this thread while i get all the info ready and post it at once... Unlike other competitors, i like to share what products are out there and where to get them for what price so we can all have some fun I've been talkin on another forum about this one particular battery brand and is sparking some big interest in the car audio world so after talking with the company over the phone about specific questions.. i think it's time to share some information! So.. give me a couple hrs or less, hopefully a LOT less time and i'll have this thread the new hot topic for a while... Direct link- http://ww…

i have a 2010 Nissan Frontier with a 110a alt. right now i have an saz-1000d and 180w 4 channel amp on stock electrical with very minimal headlight dimming at full tilt. will the big three and a kinetik hc2000 near my amp be enough for me to run a crescendo bc2000 and my 4 channel?

Did a quick search on the forums and came up empty. I saw somebody post a link to one on ebay a while ago, but I can't seem to find it. I'm not positive that that is the correct name... When I say voltage meter, I mean something like this. Feel free to correct me if I'm using that phrasing incorrectly. Just wonderin where I can find the best one for the money.

I need copper ring terminals and fuses/fuse holders, and I was wondering if you guys had any websites that sold the best ones. I've searched ebay and a few other sources with some luck, but I'm just wondering if there's a better place to get them.

So my amp keeps cutting off the power to my subs. It mainly occurs when I try to get my subs louder. It didn't do this as often a month ago. I think it was after a day of delivering pizza with it bumpin all day, amp got hot and my fuses blew, I believe ever since then it's been acting like a wimp. I'm wondering a few things I have stock electrical system, would the amp protect itself because its supply is inadequate? my subs run 300rms my amp runs 900rms, did I ruin my subs which is causing my amp to protect itself? (that would be awesome, been tryin to swap them out but gotta hurt em first) whatever it is, it keeps randomly protecting itself and when I turn my HU off…

ok, the problem is there is a noticable humming noise comming from my t1500-1bd, and its from the amp, not speakers nor subs it is a high pitch noise, and the worst is that when i turn the bass knob, the bass is louders, but then suddenly you start hearing the pitch noice more, and distorts, thats when i need to lower the bass knobs any suggestions thanks

Im installing 4 super tweets(8-ohm each), 10 cadence mid-high 6.5 (8-ohm each), 4 kicker 8" comps for mid-bass (8-ohm each), and a cadence 5 channel amp. (tweets wont be amp'd) I have no crossover or processors yet. My question to you guys is, how would I make this work? And what do you guys suggest I buy as far as crossovers and processing?

I was wondering, are Audioque amps comparable to Sundown amps?

Anyone out there know of any 2ch or 4ch full range amps that can handle 17v? Most seem to be 15.5v-16v MAX. Dont really like the idea of running half a dozen step downs Thanks, Am

Anyone know of a good voltmeter for the single-din spot don't like the look of that emptiness. I know of stinger but want a smoother look.
