Ok so I'm running two sundown sa12's vented at 38hz 2.0 cb per sub on a saz 1200d whats probably the lowest I could safely run my ssf?

I am getting 15's very soon. Two aq hdc3's off of a 2200d. My electrical now is a 200amp alt, 1/0 big three, and yellow top under the hood. All this is on a diesel engine, that of course runs at lower rpms than a traditional gas engine. I have the smallest pulley I can put on the alternator already installed, and am scared the voltage may not be enough to back this system. Would another battery be needed? If so which one, and for the best price? By the way, this is a daily setup.

I am just wondering, how do you calculate the voltage output of an amp? Also how do you calculate the amperage output?

My first question when you change the bass level, middle level and treble level it controls all speakers including the ones on the amp? The levels go from -8 to 8, right now I have the bass at -6 (usually its at -8), the middle at 4 and the treble at 8. How do you tailor made these settings. My second question is the bass level has a Bass F(40-120hz, I keep it at 40hz), Bass Q(1.00-2.00, I keep it at 2.00) and Bass Extend (off/on, I keep it on). Could anybody explain what these settings should be around or what they mean (I know bass F is frequency) or if I should even mess with them? My third question is the middle level has a Middle F (500-2,000hz, I keep it at 500hz ),…

I have not been able to find an unfused distribution block for 1/0 gauge wire..... it needs to connect like 4 0 gauge wires.

I just recently got a pair of DC Level 4 18's for my 2007 Suburban. Now I want to try and focus on my front stage. I'm not looking for competition SQ here, just something that will be on par with the 18's until I turn the bass knob up. I'm mostly listen to rap and R&B, but I've been known to listen to all types of music. It common for me to listen to Project Pat and then turn around a play some Hall and Oats, or Phil Collins. That's just how I roll. It also doesn't help working with a co-worker who doesn't listen to music pass 1990. At first I was thinking about going with an active 3 way setup using some raw drivers from partsexpress.com. You know maybe a pair of Da…

i have a par of rockford powers in the front, 75 watt rms, and a pair of alpine typse s in the back, 85 watt rms. about what size amp do i need?

Ok, so i put my amp in advance and if anyone has experience with the t30001bd the top for some reason doesnt get tight. Any idea what i can do to stop the top from rattling?

i just had some weird dreams i was being bitten by blackwidow spiders on my left hand and woke up in a panic. (i'm terrified of spider). so it lead me to go to soundstreams website to look at what kind of amps they offer. i see this D tower thing looks pretty sweet. anybody have any experience with it? i found a place on ebay that sell is it for 328 each. they only problem i really see with it is you cannot lay it down. ebay D-Tower also that cant be right... can it? direct 4 awg power?!

I've been considering getting a new sub amp, mainly looking to switch to class D for the increased efficiency. I'm currently running a Rubicon 702 on my sub and a 100w amp on my highs, and my lights dim at night when driven hard. My final system will consist of about double that much power, so I'm looking to switch my sub amp to something more efficient since I don't want to do any electrical upgrades other than upgrade the battery. I'm looking for something that'll do ~700-800w into 4ohm, 1200w+ into 2ohm, and being 1ohm stable would be nice just to keep my sub options open in the future. Had my eye on a RF T10001bd since I've seen some pretty insanely high efficiency…

What are some good 4 channel amps that can run 2-way active off of them. Something between 100-150 RMS. I would like to spend $350 or under.

I would like to ask this question as a thought experiment to determine if I am properly understanding the following relationships with wiring and power. Our speakers get AC out of our amps and our amps get DC from our power system. The DC power does not have frequency as it is a single flowing direct current and as such the flow of electrons through any wire have ZERO skin effect as skin effect is only applicable with frequency of transmission. What does play a part in power capacity however is the material of which the wiring is made of and how it is made. The total measured DC resistance of a cable of X size will be lower in copper material than it wi…

I have 4 2600watt amps if i get 4 kenetic 2400's what size alt would i need to power these amps and recharge these batts and what company has them for cheap also can anyone machine or know where i can get alt brackets for the low in case i need 2 alts the car is a 2002 chevrolet suburban

Ok here's my problem. Whenever I turn up my Head unit (New Sony Xplode) past a certain point my amp will shut off. As long as I have my amp turned pretty far down it wont do it. But I feel like I'm being robbed of the potential of my speakers. I thought that maybe it was the amp so I took my other amp out of my other car and it did the same thing but even quicker cuz it's a 900w Lanzar and the other one is a American Pro 600w. I've checked all of the connections way to many times and never found any problems. Someone told me that the ohms has to match up on the amp and on the subs but i've never heard of that. If any one has any ideas please let me know i would app…

Sundown SAE-1000D Rockford Fosgate T10001bd Memphis MCD1000 Phoenix Gold Xenon 1200.1 Am I even heading in the right direction in where to look for an amp? I'm pretty sure i've got it down between the Sundown and the Rf, but I'm open to all suggestions. Thanks. Jess

Ok well i got rid of the D3, and got a CDA-9887. LOL, bid difference i know. But before i've even done any sound setup or tweaking my subs instantly sounded better after they were turned on. But DAMN there are alot of sound options. I tried for 10 mins just to setup the HPF so i can take the bass out of the front and rear speakers to no avail. Needless to say at this point i feel kinda dumb. But i've been really busy today so i haven't had a chance to read the manual. I knew this deck had alot of options but man this is rediculous. I still have the stock hi's in my car but i plan on changing them out. And i know that everyone is going to say go ACTIVE. So before…

Serious issue going on with my system, and I know it's gotta be my electrical..... just need some advice on where to go. I've only had my system in since April, and I've noticed at times that my front stage will suddenly begin losing treble, then volume. I turn it down and it recovers pretty quickly, within a minute..... but will do it again if turned back up. I have not upgraded the electric at all.... was hoping I wouldn't need to being that I'm not pushing a lot of wattage. Amp is a Kenwwod7005PS 5 channel..... manual says it pulls 56 amps. I'm guessing my Scion xB 80 amp alt just isn't enough...... but would doing a big 3 help this??? (I have some 4 ga left over from …

1st off let me say that a dd1 is not currently available anywhere around me at the moment. And I just got my system installd so I wont be able to afford a dd1 for a month or 2. Also no shops around me have a scope (dont ask me how they set their gains). So I have to temp DMM set it. Question is ive read alot of people saying to set it to the HU preouts which would be 2volts. Even on volume 29 the gain is pretty much all the way down at 2 volts. Or do I set it from the watts/ohms chart that ive seen around the web? Which would put me around 38-42volts? Which of the 2 should I go by? Also what setting do I set the DMM to, I know its Vac, But is it 200, 2000, ... ? Any info …

I just received my SSA Icon D2 sub today after a longgg wait, between the box, and then the sub. So I am anxious to get everything installed, but I don't want to make any mistakes. I've been looking at this wiring diagram to wire it in parallel to 1ohm. And then from the manual I am planning on wiring it like the top picture. I'm a little confused by the diagram in the manual, I can just connect to 1 positive and 1 negative, right? I will set the gains using the stickied tutorial. What should the subsonic filter and LPF be set at? Are these lower and upper cutoffs for what frequencies my subwoofer will play? Bass boost and phase should be set at zero, correct? Are …

I have the 9813 model head unit it has a time delay feature , easy to set by plugging in your speaker to listening position. Alpine`s web site can give you the settings for your TD . The Bass Focus is a separate feature but when adjusted it affects the time delay. I would like to use the Bass Focus but I do not understand the instructions completely. Is any one else here using this feature and how is it set?

i was @ Harbor Freight and saw an analog Volt meter that bosted different color LED's for $19.99 so i got a lil help from Alan Hall and well minus 1 smaller cup holder later... 3/4" Mdf wrapped in Blk Vinyl heres the installed pic off on with motor off on with motor running different colors not bad for a cheep fixx, waiting for Stinger to replace my digital volt meter. http://www.harborfreight.com/cpi/ctaf/disp...temnumber=98479

Starting yesterday my sub will play and then stop. I'm running 1 psi 15 inch platform 2 sub wired to 4 ohms on a hifonics zeus 3200 watt amp. The hifonics light on amp will still be illuminated but the light on the bass knob will fade until it's off completely. When I restart the car the sub sometimes will play and other times Not. All wires are secure. Any ideas?

Alright.. i ran into these things they call line drivers.. lol.. seem's pretty simple. rca's in then rca's out and bam.. higher voltage.. is it as straight forward as that? is there anything to watch out for? i see several brands including pheonix gold, rockford, hifonics and audiocontrol.. Do you guys use them? if so what are your thoughts? Just trying to get an idea of these things from all of you before i go out and buy one. cause so far its got my attention... thanks for any info you guys have.

Does anyone know the diameter of the crankshaft pulley in a 1997 stock 5.7l 1500 chevy suburban? My suburban is in the shop right now getting the fuel pump replaced but i just wanted to know so i could go ahead and order a new alternator from mechman tomorrow. Thanks in advance!
