ok i know people on here say not to bother with a capasitor but almost everyone in my town here is telling me not to get a 2nd battery b/c it's not going to be as good and i'm wondering y you guys reccomend the battery over a capasitor? they tell me that caps are made for letting big draws out and batterys arn't ment for that, now i'm unsure what to do it's for a daily system a sundown saz2000d and fi btl 12" and big three 1/0 wire.

I have 2 large 100aH AGM batteries in the rear and a factory sized AGM under the hood. A cpl weeks ago I went to start the van and it was dead. I got it started and voltage was terribly low. I only ran it for a few minutes then let it sit, restarted a few times for a few minutes...I dont have a charger. After a couple days everything seemed back to normal. I watch the factory gauge a lot closer and am surprised at how much voltage can change day to day while running, independant of hot days to cold days. Some times it runs around 13.5V other times 14.2V, even in the same day, sometimes 14.2V when its warmer and been driving and sometimes 13.5V when its colder and/or less …

hey everyone, so today i went to harbor freight tools, got a DMM on sale for 3.00 dollars, the name brand was cen-tech, heres the link CEN-TECH MULIMETER so anyways i got home, logged on, looked on the stickies for the Setting gain with DMM tut and i done everything i was suppose to, minimized HU Settings,bass,treble,etc, used a 50 hz tone 0 db, and when i connected the DMM to the speaker output with no load, i had to set the gain almost at 3/4 to get my voltage i have a hifonics bxi 1200 watt amp at 1 ohm load on 2 12" pioneer 308D4 rated at 400 rms per sub HU is kenwood MPC205, 2 volts at sub pre-out 1200 wrms at 1 ohm load so 34.64 Volts is what im striving for on my d…

I kow that I've asked some of these questions before, but a few ideas came to my head this morning since I'm not satisfied with the results. Equipment: 10" AA Arsenal Sealed enclosure Factory Headunit 1 Stinger LOC 1 ZED Minilith Here's the deal. Everything is connected well. I have a good ground, wires, and RCA's. The sub is getting a bit of a warble sound to it a low volumes (I'm sure it is still there when the volume is up,but the music is covering it up). In order for me to get any output in this sucker, the gain has to be almost all the way up and I don't like that. Something is wrong. Here is what I've been thinking... I really think that a four channel LOC would be…

Hey guys, I'm new here but been messing around with audio in my cars on an amateur level for quite a while. I recently decided to do an amp/sub install on my newly acquired 2006 Infiniti M45. It has a factory 14 speaker BOSE system. As far as the audio upgrades I've added is as follows. -Sundown Audio SCV3000d amp -1 Sundown Audio X12 @ 1ohm in ported box to spec -0 gauge wiring ran to trunk to additional audio battery and capacitor -6 gauge wiring from amp to sub -LOC taped into the stock Bose sub inputs Problem is that the sub doesn't sound nearly as loud as it should although the sound it does produce is very clear. I went from 2 SA…

My current setup consists of: -Advance auto parts group 34/78 up front -stinger spp1500d in the back -mechman 270a alt -Crescendo bc2k -Crescendo c1100.4 -Knu konceptz 1/0 all around including big 3 I was wanting to upgrade to something bigger (maybe a dc level 6 18). I am tore between 2 options...(both options will have c1100.4 and same batteries plus some later down the line) 1st: -Taramps hd5000 -2 positive runs of sky high 2/0 from front to back -3 positive runs to the amp -Big 3 in sky high 2/0 2nd: -Another bc2k strapped to the other one -1 run of sky high 2/0 from front to back -2 runs of knu 1/0 or 1 run of sky high 2/0 to each bc -big 3 in sky high 2/0 I can sav…

Well, I've been looking for a ho alt for my brother's Caliber and so far, the only company that has said they can/will build one is Excessive Amperage. I was wondering if anyone here had any experience at all with them. Nathan said he would build me a 200a unit that will do approx. 130 at idle. He also said that the alt is controlled by the car's computer and suggested I also purchase an adjustable external regulator from him for another $135. I'm not sure I need the regulator as we don't ever plan on running at higher voltage. Any input is very appreciated.

I recently acquired a 15 inch MTX Terminator, all I need is wiring and an amplifier but I don't know how strong of an amplifier I need because of how old the sub is. Can anyone help me out? I really don't know much about sub/amp combinations. A picture of it http://imgur.com/a/qeulw

ok so my friend needs another battery terminal that has 2 1/0 openings. his other one for the positive has a 1/0 4/0 and 2 8/0's anybody know where i can get one with 2 1/0 guage inputs

I noticed this when I did my first Install and I didn't think much of it at the time because I was assuming my Alternator had a major roll to play with this. I received and installed my 270 HO alternator from DC. I am still getting really bad voltage drop at idle. Well i am driving it's fine i stay at 14.4-14.6... Once i hit a red light it drops down 12.2-12.4ish. If the heat or AC is on at idle i wanna cry The only thing i have running in my car at the moment is my sundown 100.4 and i have 2x XS d3100 installed. 1 in the hood and 1 in the back. I did some research and I read on trailvoy.com that the car PC tells the alternator to shut off at idle....called a dealership…

Hello all, Quick question about wire gauges. I did some research and found Recommended Power and Ground Cable Size so think I should be okay, but wanted to check in with this community first. Currently, I have 1/0 power cable running from the battery to the back of my truck. It hooks into a distro block and from that block I have two 4 gauge wire roughly ~2 feet or less connecting to two amps. One of them is 1000rms mono amp, and the other is a 100.2 amp for my front speakers. If I upgrade the 1000rms amp to 1500rms, will the 4 gauge wire be able to handle the extra power since it is only a very short distance? The ground for the 1000rms amp is also ~2 feet…

I inserted my DD-1 disc into the KDC-X494 in my boat to set levels, and the CD won't eject. I press the eject button but it acts like I'm not pressing anything. Doesn't display eject or make any attempt to when I press it. It just ignores my pushing of the button. I tried pressing the reset button under the face, but no help. Any ideas? Is is a common Kenwood issue? How do I get my disc back!?

Im upgrading my BASS and i was thinking of buying the rockford fosgate T20001bd, anyone know these amps. I was going to try to buy a 12" btl to run off of it as well, do u think it is a good pair up?

im running a pioneer AVP3100 dvd and my question is im trying to hook up a toggle switch to the picture wire the from the HU ( supposed to be hooked up to the E brake) so i can see dvds while trying on trips and i hooked it up to toggle switch+ and ground the other side to chassis but it wont work... and it worked when it was in my other car 3 weeks ago. its not the same toggle switch that i had before. its a little smaller but still the regular old easy toggle switchon/off switch , + / - wire leads)... anybody know why it wouldnt work?? could it be the toggle switch?? or would anybody else know how to wire that up so it will play dvds? thatnks in advance

I'm looking to replace my stock alt. But I'm in a small budget can any one give me their inputs regarding these alt? And maybe a ball park guess on how much it would be to replace my stock 140A alt I have a 2000 Acura integra ls.

Had to disconnect my radio for trouble shooting and when I hooked it back up with yellow to yellow red to red it dosnt wont to power on unless it's hard wired yellow to red.. I have a extra orange (illumination) wire left can't remember if it was hooked up or not please help so I don't have to take my deck out everytime

So did it? tell what you have for electrical as well I have a DB electrical 250a alt, big three XS power d3100, SAZ-3500d Basically, my question is according to your experiences, will multiple runs help me?

Im lookin for a good 3000w rms amp. I found a Alphasonik PMA1000HCA and I dont know much about them. But the Crunch Iv read some Good things about it. Who makes Alphasonik is it a division of Audiobahn??...I think I read that some where. Any way Thanks for any help Im open for any suggestions in the 500$$ range Thanks

Looking for new mids and high amp, came across soundstream HRU.2 does anyone have experience with this amp? Thanks

I know this is a really stupid question but I want to make sure I'm tuning my amp correctly. On my amp the subsonic goes from 10hz at its lowest and 60hz at its peak. If I turn the dial to it's 12 o clock position is that 30hz or is it 40 Hz due to it starting at 10hz and not zero? Same with LPF. At its lowest it's 35hz and at its peak it's 300hz. At the 12 o clock position is that 150hz or is it 185hz due to it starting at 35hz and not 0?

I've always ran 1/0 power and grounds on my systems.. 2 situations I've ran into.. 1. My dad is ALWAYS telling me I should run 4awg wire, thinks 1/0 is way too much. Almost as if its bad to run a wire that size.. my system isn't huge just a sundown1500 another ~600 rms highs amp with a ho alt...is that just an old school way of thinking? 2. I recently bought a bunch of 1/0 CCA knukonceptz wire and I think I'd rather go with some OFC instead. Friend of mine has recently bought a audiopipe 1500 from me and has no wire. Stock everything..I want to sell him all this CCA wire I have to buy what I really want.. my original thinking is it should work fine (after adapting to 4 GA…

Looking at the KDC-X792, looks like its got all the right features. 3x4v preouts, USB/iPod connection, aux connection, 2nd aux option, PAC wire, attenuator, 24 bit DAC, and the oh-so-handy Attenuator aka "Oh s... a cop" button. I like how it looks, and it sounds like I could integrate it well into my future car, with the USB jack replacing the stock iPod connector, and rewiring the stock 3.5mm AUX input to go to the HU. Anyone have any experience with the Excelon HU, especially the 79x series? SonicElectronix has it for $229. Your thoughts on Kenwood in general? The Alpines don't really float my boat with all the buttons bunched up on the side.

is this amp realllllly under rated or sumthing 1.5k at 1ohm...for a 4k D? this isn't just for flakko lol anyone else can chime in it was just bothering me why its marked 4000d and its power is 1.5k

Which amp is better and why

Ok guys i might be opening a can of worms here but i dont understand why people do this to set their gain and think its right. to me, it doesnt make sense and i will explain why. a lot of times i see this chart here and people say set it for xxx voltage and you are set. ignore step 4 since without having a load on the amp is kinda pointless. if that chart is right, then i am putting 1300 watts to my sub, but with a clamp, DMM, and thanks to ohms law, i found out i am putting ~800 to my sub. i am not saying that chart is mathematically wrong, just cant be used the way its intended. so whats the deal? i dont understand why you would use that chart (or any formula equivale…
