Seen a few videos, made in Brazil anyone have any info?

i will be running 2 sa-12 d4s need help on what amp i should get both seem realy good !! i can get a refurb sundown for 320 shipped or i can get a crescendo bc2000 new for 339 i like the fact that the cresendo is new and i love the color scheme but on the other hand i think the sundown will put out a little more please help !!! i no i have been a pain lol keep changing my mind over and over and have been talking about doing a system for a while but i have one sundown already the other will be here thursday and like i said im ordering my amp tomorrow just want to make sure theres not something im missing i think i would be happy either way its going to be an upgrade…

alpine's site doesn't say anything nor does the manual, but do you think the MRP-M850 would operate at anything below 2 ohm? i have a dual 4ohm 10" RL-i and i have decided i want a little more bass, so i'm wanting to get another RL-i. thing is my options are 4ohm or 1ohm if i do so. at 4ohm i'm not going to get more wattage than i'm running now at 2 because i'm only running it at about 500ish. i'd really like to not have to buy another amp though along with another sub. so you think it could handle 1ohm even though it says nothing about 1ohm? ratings RMS Power (at 14.4V THD+N, 20Hz-200Hz) Per channel into 4 ohms: 500W x 1 (0.08% THD) Per channel into 2 ohms: 800W x 1

I am getting a lot of different noises coming out of my speakers. I have had this problem for a while. I thought it was my pioneer head unit but I guess that proved to be false. I have installed all new grounds and everything is wired correctly. I am getting not only alternator whine but ... noise from when I turn my fans on (ac/heat etc) and the noise increases as I increase the fan speed noise when I turn my signal light on or yield lights on - they noise pulses to the clicks of the signal lights noise when I turn my interior lights on and as the lights dim the noise dissipates. The wierd part is, if I turn my car onto accessory the noises are no longer there. These no…

Would it be easyer running a 2 way active front stage by getting an active capable head unit or crossover/ processer? My amps will probley not have crossovers on them

I was just wondering if this is possible, or even worth it? I have never seen any manufacture attempt this, but I believe that it would improve the quality of the sound as well as be cost effective in the aspect of less material/weight/mass that three sets of RCAs use. I'm not sure if anybody will be able to answer this question, but I was just wondering what is the reason for manufactures pursuing this route. Any opinions are welcomed.

Just ordered an Alpine 9887, i still need to use my onstar daily. i know PAC makes an intergration for this but its like 90 bucks. dose anybody know of anoyher company that dosent rape the consumer? that price is an outrage!

i want a 2000 sundown but dont hav the money for that right now so these 2 amp is my next choise wat the diffence b/w the 2 which one is a better buy an why ill be running 2 SA-12 with 2 yellow top batt , stock atl with the big 3 thanks

Is the DMM method a fairly accurate way to measure the watts output of an amplifier? I set the meter on AC volts, connect leads to speaker terminals (w/ subwoofer still hooked up), play a sinewave burp and take that reading to determine how many watts went to the sub. Does that sound correct? I already set the gains w/ an o-scope so I'm not trying to do that. I want to calculate how many watts actually is going to my sub thanks

Does anyone know a good place online to buy 4/0 guage wire from?

Anyone have any first hand experience with ct sounds amplifiers? I'm considering their 7k watt amp but I been reading mixed reviews about them

will i saw a car with a pc in it over the weekend and i want to do it but don't know it it is going to work better the a head unit so if have done this or if you know if i can do a sq build with it

What is the difference in using a AGM battery instead of a Gel battery when running a secondary battery for an audio system? If the Ah and Reserve Capacity are the same or very similar in both batteries, then how do they differ?

hey guys my buddy is trying to decide between a Rockford T-1500 or Sundown SAZ-1500. i know this website praises the Sundown's, but WHY is it better then the Rockford? he said his budget is whatever it needs to be. he is running a pair of 15in IA Lethal Injections. he has them in his Jeep Wrangler. his electrical is all stock, but he is also in the process of getting a battery. Thanks guys.

I recently installed a new amp. I had a Sundown saz 1500 on my btl n2 12", and now I run a Sundown saz 3000. The box is 2.1 ft3 net, slot ported to 32 Hz. I am a little ...worried ! I thought the change would be HUGE, but no, it is not ! I think it's louder, but I've never mesured it. Do you think I expected too much from the new amp ? My electrical seems to handle that power fine, I did not expect that !!! Only 2 batteries on a (solid) stock alt. I have a diesel engine.

Well I was planning on getting the Sundown 2500 until it went to 815 dollars, there is no way I have the money for that, I can dish out maybe 600 tops...was looking at the HiFonics Brutus 2400, but I dont know if they are good or not, everywhere I have looked they have positive feedback...any suggestions??

It's time to start doin some more research so time to get as detailed as possible with how to do this. I am planning on installing air ride in my car soon so i can upgrade my small 12v battery bank to all 16v batts and swappin my mechman alt with an external regulated system charging at 19v. This will be for me and everyone else interested in doing this- 12v batts float around 13.0v. They typically get charged with a 14v alternator at 14.4-14.9v. 16v batts float around 17.3-17.9v. They typically get charged with a 18v alternator at 18.5-19.3v. So now we got the basics covered. Most car audio amplifiers are not 18v capable. There maximum voltage input ranges between 15-…

i was wondering if the audiopipe ap30001d can run at 1 ohm stable??

Does anyone have any experience with a Digital Audio DHC2154? My only concern is can it do 1000 true rms at 1 ohm. I know its not a great amp but my kicker 1200.1 was stolen and I am trying to work through college and dont have alot of extra right now. A guy on realm of excursion offered it to me for $150 shipped. Is it worth it?

Hi there I just bought a 15 inch nightshade and need to pick an amp to run it. I want to get an amp that can run it at 2 ohms. Money is a lil tight,.. I was thinking about a hifonics brutus that does 1700 at ohms or a Power acoustics that does 2600 at 2 ohms, these are affordable amps but i dont know how good they are or if they over heat i would love some suggestions or links to amps that can run a 15 inch nightshade and get it LOUD without over heating or messing up the battery or alternator and is efficient and all that.. if someone is selling an amp that can push this sub please let me know. thanks!!

Looking at a 100.4 sundown going active up front... 6-1/2" midbass and 1" tweet in the doors... Deciding which of the 2 units will give me better control with going active... And also which of the two is just "better" overall... though i feel it's not really important mentioning but the subs is powered by a saz3000D on 2 BL 12" I also have a 300amp iraggi alt and a yellowtop upfront and a kinetik hc24000 in the rear... Anyone have experience with these HU's let me know please...

Okay guys i ran into a problem, i called DC Power and they said they DO NOT have a dual alternator kit for me and without one i WILL have major voltage drop. (I TOLD THEM MY SYSTEM HAS 10,000 WATTS ~ rough estimate) I DO NOT want to drop really low because this system will be a DAILY DRIVER, so i will be playing a lot and i don't want to limit the usage or anything of the sort because of voltage drop. The biggest alternator DC Power had for me is a 320 Amp w/ 180 idle. (I'd really like to go with this company) The Sub Stage; (2) 15" AA SMDs (3500W power handling ~per sub) (2) AQ3500D.1 (1 ohm power @ 14.4V @ < 1% THD 4300W x 1 ~per amp) (4) XS P…

Its been awhile since I posted. But I'm back in the stereo business now. And the shop here sold someone a Power Acoustic "CAPCELL" 800-amp. 2 months ago. She came in today and her woofers basically sounded like they were crying. She thought they were blown. I crawled in and looked and the Capcell was displaying 8.24v and when it would hit would drop as low as 6.96v some time. Basically I don't have any experience with capacitors because I dislike them. But this is a hybrid so I wonder how can I recharge it. Just hook it on a battery charger for a few hours? The system is a SPL GRLA5500.1 on CVX154ohm x 2 http://www.poweracoustik.com/pa2006/product_AUDIO_addon_CAP…

Just finished some power testing on the Arc Audio amps that I did a review of, there posting on my site n2caraudio.com. If anyone is interested.
