i recently bought a fi bl 15 dual 1 ohm sub and in desperate need of an amp with 0 guage connectors

So I went to a local car audio shop today to see if I could use their DMM. I wanted to get voltage and amp readings to see what my amp was really doing. Of course, first thing he has to be a funny guy and ask me if i need new subs because I replaced the ones I bought from him with a BTL. He lets me use his occilloscope and I take my first reading with car off at batt. 15.5 VOLTS!!! Uh...Wtf? So then Im scared to even start the truck and see what it says then. 18.3 VOLTS!!! SHIT!!! Jumped in under the hood and turned the external voltage regulator set screw all the way down on the alt. This screw was never adjusted by me at all before, mind you. I installed the alt and le…

Anyone have the dimensions?

Okay I lack proper knowledge in many spectrums of electrical. My question here is hypothetical but, if I had a battery bank of lets say 6 Kinetic 2400's all connected onto a buss bar. Lets say I have 4 alts. 2 put out 240 amps at idle, 1 puts out 250, and another 275. All 4 alts are connected to the buss bars by 1/0 cable. Would this cause issues with the reliability of the batteries or the alts? I just wonder is mis matched alts make a difference. J

Ok, so yesterday I was warming the car up for an oil change and started beating on the system a bit. I noticed one woofer not moving quite as much as the other. So today I took all the speaker wire out of the amps (2 bc3500's strapped) and each woofer is reading 4 ohms??? It's supposed to be wired to 1 ohm per woofer 2 ohm strapped. I don't know what I did wrong. I'm not sure if there is a different way to check impedence if the amps are strapped.? I notices the master amp gets slightly warm and the slave is cold. I need some advice as I'm gettign frazzled. The woofers are 2 fi btl 15's Dual 2's I put a camera inside the box to make sure no wires came loose but everything…

Ok so I am really good at buying stuff and then finding out it isn't as great as I expected.. and then have to sell and re-buy something better... SO Please help me get the right amp the first time! The SA-10s are rated at 600rms each, Im sticking 4 in my hatchback and want to get a good amp to meet them. They are d2 and will wire down to 1ohm! I have seen people stick a SAZ-2000 or AQ 2200 on 2 SA-10s... But I want to know if they can seriously handle that much? I mean 600x4=2,400w but if they can HONESTLY handle more I will try to find a way to get a more powerful amp.. YOU guys have used these and know what they throw down, I have never used any sundown sub before an…

I have a lil over 700$ to spend on an amp for my 18" BTL I was thinking on buying a Rockford Fosgate T20001bd for a lil over 700$ And money is kinda tight with college coming up and bills and such.. Or just wait and save up a little more cash and get the Sundown 3000D Its really just a ground pounder and im not really concerned about numbers on the mic.. My question is, Is that Rockford a good amp to push my BTL? I just know how Sundown is all good talk and wonderful customer service..

Well, I've installed a complete new system in a friends SUV (minus a headunit). Everything is going great and just trying to tweak thinks a bit. One thing that is real obvious is the low bass extension. Is this a problem with having a LOC instead of an aftermarket unit. I have heard that this can be a problem in my situation. Is there a cure for this? I would like her to have full range capabilities. Thanks.

Optima yellow top is 150 at auto zone. I heard that the Everstart batteries would be just as good and thier only like 60 at wal-mart.. which one, i cant have 2 otherwise i'll be in street mx3-4

Alright, so I've done some searching and can't find any posts similar to what I'm dealing with. The closest I can find on google is something referring to the battery current sensor. Aparrently its only on 2005+ Tahoes though, but it senses draw and adjusts alternator charging output accordingly. Mine is a 2000, and when I went through my Big 3, I saw no such sensor as expected. The issue I'm having is a lot more noticeable now that I have a Stinger volt gauge in the dash (Installed same time as new HO Alt, 9/11/19) When I start up, I'm at around 14-14.3v.. after warmed up, 13.9v is consistent. Now... I've notice multiple times that when I am coming to a stop, or slo…

I can’t find anything online on these amps. Leaning towards the crossfire 6k but I would to see clamp results starting at .5 and around 1.2-1.8 ohms after rise between 12.8-13.5 volts ok the new model dd m5 and crossfire xs 6k.

any 1 use these amps and which one puts out more power http://www.sonicelectronix.com/item_25297_Planet-Audio-BB1400.1.html

i was thinkin i wanted to get a 3000-3500 watt amp for 2 15" BL's but i just thought to myself that im not goin to compete with them, so is having the extra 250-450 watts really worth it??

I'm about to grab up a normal ANL fuse holder from Knu when I notice they have this "high current" fuse holder that uses multiple mini ANL fuses instead of one big honker like the normal one, (not the mini). They say it will have "lower voltage drop across the fused surface area" as well as handling higher currents. Is there any validity to this statement? Has anyone had any experiece with one of these to know if it really has any great affect on voltage drop? I'm just curious...

Not my choice, but this girl needs an amp that does 400 watts @ 2 ohms. List a few ideas for me.

$450 amp budget, which way would you go? I could stretch to $500 w/shipping but that's it for now Im running (2) digital designs 2512c and they are laughing at my (2) brz1200 @1ohm ea 3 yellow top optima, 220amp alt I'm not a SQ critic so it doesn't have to be Rockford, ect. I want power over quality since I'm only spending so much this time around Thanks and any input is appreciated

Does anyone know where i can get a HO Alternator for a 99 dodge durango with 5.2 magnum engine? And what about bypassing the ECU Regulator in this Chrysler work of engineering genius?

anyone heard of this brand amp? is it good? what do yall think about it?

What do I need to do for the big 3? Do I need to upgrade alternator?

Hello all, My name is Dave Edwards, I'm staioned in Grand Forks AFB, North Dakota, I WAS in the Air Force, I just finished a 5 year tour. I am so damn close to my BSEE degree I can smell it---4 years in work. I have been into car audio for about 12 years, I rebuilt my first amp when I was 13, now I build amps,subwoofers,crossovers, pretty much anything I need. I worked as a System Designer/Consultant for Ampmanaudio.com before it went under. I try to learn as much as I can on the subject and I hope to pass my knowledge onto you.

how much resistance is too much on a grounding point? Ive already read that under 1ohm is optimal but after doing some checks i'm just not going to get that in the rear in comparison to the front. my lowest reading in the back was between 1.8-2.1 Is that good enough? My next question is on the power wire. I'm using the rear battery as a distro for my amps. measuring from front to rear then from amp to the the end of the wire is normal. but when i connect all to the battery the rear battery and measure I'm getting 30+ ohms on all connections in the rear even on the wire that is coming from the front battery. also this occurs on both ground and power wires. the battery is …

I have read a few things that say that a 2nd bat. is useless unless competing because in some comp. the motor is off.... as i do not compete i was wondering if a 2nd bat would be usefull to stabilize voltage or a HO alt. I have a 2002 grand prix gtp with the big 3 done in 4awg knu knocepts wire and some 4awg monster cable. I have a sae-1200d.v2 and i am going to be getting 2 sa-12s. I am hoping to have both loud and good sq system in my car? just wondering what others are thinking and comments... thanks

Like the title says im trying to wire up my components. They are Infinity Perfect 6.1, and im trying to use a kicker kx 250.2 amp. I know I have to bridge the amp to get 4 ohms but every time I wire it up the amp shuts off at high volume for a few sec ds and then tries to kick back on. Some info: 0ga run from the battery to a distribution block From distribution block 4ga to Hifonics 1208 Brutis, 8ga to Kicker kx 250.2 Same size wire for ground to another distribution block and 0ga to frame 200amp alt. with big 3 done SO my question how do I wire this up so I know im doing it right, and what could be making the amp shut off?

My radio make my subs "pop" when I change tracks and turn off the car. I have tried replacing the rca's that didn't help. differnt head unit stopped it. But I wanna try to keep my kenwood. Any sugestions. I have heard that there is away to stop it just don't know how.
