im thinking of giving my bl's and 1500D to my brother and saving up for some BTL's and a new amp. ive decided i dont really care about good sound quality with my subs....i just want loud ass bass something that doesnt sound horrible, and something that can take abuse, and i know these can...and i love Fi subwoofers. i know autotek makes good amps, but would this be a good one to power 2 12" BTL's or is it too much? also, they are rated at 4k watts rms, but how many watts do you think i could get out of them? http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=18160 the 3000 and 4000 are both the same price on onlinecarstereo.com so which would be more practical? info…

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…

So I'm going to be running active soon. All crescendo. I already have the soundstream rubicon 2.600. (300w x2 @2ohm) so I'm planning on running that on the 4 crescendo 6.5s. Since it seems the perfect fit rms wise. I also already have a Lanzar VCT4110. (100w x2 Bridged @4ohm) Ive heard these are overrated, so input on that would be nice. should I run that bridged @4ohm for 100w on the 2 crescendo ft1s. Orrrrr.... buy a soundstream rubicon 2.250. (75w x2 @4ohm) It is closer to rms, but I know the ft1s could handle 25 more watts. Thought of soundstream only so they would be matching, it would look nicer, although the Lanzar is already mounted under my front seat. O…

I have a 2.2L 2002 Oldsmobile Alero and am having a tough time finding a high output alternator bigger than 150amps. I'm just wondering if somebody has this car and purchased one, I called a place and they said an alternator made for a 1999-2002 Chevy cavalier MIGHT FIT, so that's a take a chance and hope you're right. I am running 2000 watts right now, my alternator fried today and have been searching for hours trying to find one but nothing comes up. I figure I might as well get one now instead of wasting $100 to get a new 105amp one. Otherwise would a second battery work after the big 3 upgrade? I have 2 1000 watt alpines and 2 pioneer premiers ts-w3004spl but will be …

hey guys, i have been thinking. right now im stuck on which amps to use on these solo x's. its between 2 kicker kx 1200.1's (i can get some decent deals on) or i just found the soundstream rubicon series 1600 watts amp (id get 2, 1 for each sub) there rated 40Ax4 which is 160A for $220 new with warrenty. iv been doing research and they do right at rated power. so what do u think. im stuck here HELP!!!! if anyone knows of some other good rated power amps (around 450 for 1 or 225 for 1(id buy 2) let me know. ps, im ordering my 220 amp alt. here soon and 2 optima yellow tops so power is no issue here. here is a link to the soundstream http://www.amazon.com/Soundstream-RUB1-…

I dont want you all to just check Sundown cause of the Forum, i want it based off of reliability, and durability, THEN vote on favorites ;P

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!!

I have a US Amps that I can not find any information on. Throughout my searches for this amp I found a few but none that look like mine. I think it maybe rated at 1200w@4ohms. Do you think it is 2 ohm stable?

i need an amp to push my 15" btl fully loaded dual 2ohm. i cant post in the fs/wtb section so i figured i would try to see what my options are this way. i am looking for something that is 2000w+ @1 ohm stable and not too power hungry. i have two yellow tops, 220 amp alt and all 0g wire (including "the big 3") i sit at about 14.4 volts with the truck at an idle and 3 viar compressors runnin. im lookin to spend about 350 shipped. if you think of any that might wok for me please post them up. not sure if i can buy one from anyone on here cause of my lack of post but if i can just send me a pm. thnx.

so mostly everyone knows about clipping, when the music gets turned up and it hits a bass note, starts to play it then quickly drops off. well i've been having this problem ever since i got my new setup and i've read the how to set the gain of an amp thread, done it. no change and i've tested the impedance of my vioce coils and they're correct, dual 1s i've tested the ohms on the output of my amp and it's reading 2 flat which is what it's supposed to be i've re wired my sub to the amp and checked my rca's but it still clips when it gets turned up. any other suggestions, please?

2004 Explorer 4.0 Yellow Top Big 3 will be done in 1/0 when installed Stock 135A Alternator 2 15" Icons Sundown 1500 Sundown 100.4 Couple quick questions before I get a alternator & everything installed: 1 - How do I calculate how big of an alternator I need? Ive seen a couple different way but whats most accurate? Also have a 100.4 2 - Would a 200A alternator and a yellow top suffice for the two amps to stay above 13v at idle? I can try 250A if need be. 3 - Anyone ever use qualitypowerauto.com to get an amp? I want to upgrade to 200A for no more than $300 if I can

My deck is rated at 4 volt preamp but when I measured it I get 4.1 volts at maximum volume on my subwoofer RCA and 0.7 volt on my front and rear. The deck manual States 4 volt at 10 percent Distortion so my question is should I pick up a 3-way line driver, cap the deck volume at three quarters, and use the line driver to boost the one volt and 3 volt signal up to 6 volt?

ok i have a problem with my voltage. i can't seem to find the problem so i was wonding if anyone could help. I have a 250 amp alt with 2 runs of 0 gauge 3 batteries one is 100ah and the other is 139ah. Plus the blue top under the hood. The amps are a sundown 2500 on 4 12 skars and a sundown 1000 on 2 skar 8s and a old school Rockford 1500 on the highs. But at full tilt I drop to 11.8v and driving 12.2v idk what the problem could be. all grounds are to the frame and i did the big 3 all 0 gauge. all batteries tested fine. If u have any suggestions please let me know. Thanks!

So I picked up a pair of Hertz Hsk165's and need some help with choosing an amp. Amp will be ran off of a kenwood 8120. I have about 400 to spend... but I wouldn't mind spending less. Im thinking about the following: sundown sax-125.2 $240 (even a 50.4 bridged thoughts???) audio systems twister 300 $300 jl 300/2 $350 steg K2|02 $450 arc ks300.2 $399 what are your thoughts on the ones posted? any recommendations?

I'm looking for some experiences, reviews, and/or opinions from those whom use small amplifiers. Post your brand, model, and opinions. Thanks!

Ok so I installed my Stinger voltmeter last week and tuned it or whatever with my multimeter and it works perfect,.. but now that I can watch my voltage.. it is weird. Sometimes when I am driving it goes below 12v.. this is even if my head-unit is off, no windsheild wipers, no headlights no ac.. nothing on just driving and it randomly went to like 11.6 even.. I have figured out my "normal" voltage when driving is usually 12.5-12.7v... like that's what it stays at most of the time.. but when im driving I notice it is randomly at like 11.9 then later its like 11.6 and its for like 5-10 mins sometimes and then sometimes it goes back to like 12.2 or 12.5 and just fluctuates a…

Looking for a bit of advice on purchasing a new amp/amps. Ill be running a pair of D2 crossfire XSV2 15s tuned around 30hz. My dilemma is whether I would get more out of (ie more power, less rise): A pair of 2.5k amps (probably Skar 2500), bridged and wired to 1ohm each OR A single 5k amp run at .5ohm Electrical is: 2 runs 1/0 OFC (one is knu, other is memphis) and 1/0 Big 3 Kinetic HC2400 up front 3 deka group 34 AGMs in the back (55ah a piece, 750cca) 270a-320a altenator (will be added after amps) Thanks in advance for any help!

Dave Navone says that you should use a -10dB tone to set your amps gains for a 3:1 ratio overlap. Should I do that? I've been using the 0dB tones. Switch?

ok my friend has a kicker 1500, and another has a lunar 1500 (made in louisiana, really good), but the guy says its really only 500 TRUE watts, but it is just as loud as the kicker, if not better, can anyone explain this to me?

I have a question, I was rolling down the highway when one of my friends in my backseat heard sparks shooting from the battery (which was when I looked back to see my battery posts red hot and melted. I have the Kinetik HC1800 in the back, and just a stock Interstate battery in the front along with the Big 3 in 1/0 wiring. What would be the cause of this major problem??? And yes I did stop in the middle of the road to fan out the smoke in the back :( PS Ill get pictures of the demolished battery if you would like

Howdy, I need some help here. I have two FI 15 BTL subs. Double voice coil,heat ring,etc,etc all options on the sub and built for daily playing. I have two brutus 2600's run by a controller. the amps or subs are not wired together. I also have installed besides the two 850 cranking amp ford battereis, two Kinetik 3800 watt batteries. The altrnator is (was) a 250Amp altenator built by Excessive amperage. After a week to 10 days the alternator gave out. I mean fried. I never ran the system at full power because I am still breaking in the subs. What could have caused the alternator to fry?? or was it just a bad alternator?? Altogether the system at full power is +/- 10400 wa…

alright i found some battery terminals from KnuKonceptz and they hold 1/0 gauge wire. im planning on using them for the big 3 and for my amp install, my question is will they hold a 0 gauge wire? or will i have to just not get a positive terminal? here is the link to the battery terminal
