i just need a decent one to run 1/0 welding supply cables to the back for second battery. just don't want to pay an arm and a leg for them. thanks Yang

What do you consider a fully loaded 18” Fi BTL P Chamfer Y or N Cooling Y or N 3rd Magnet Y or N HiXmCoil Y or N Daily or Spl Y or N

Well it seems I am facing a "small" problem. I am looking to replace my current stock alternator with a bigger one. Anyways after searching here and on Google, I managed to find several companies who build and / or sell high output alternators, for example: HO alts, Ohio Generator, Iraggi Alts, etc. But none of those companies have a high output alternator for my car: Lexus IS 220D (Diesel) make of year is 2007. (yeah I am European). The stock alternator is already pretty high (130A), but it's not enough to power: 2x SAZ-1500D strapped & 1x SAX-100.4 (bridged) & 2x Kinetik HC1800 batteries. Anyone know a different brand or who do custom build alternators? ...or h…

Hey guys! got another topic about a new set-up idea i'm looking at Current set-up is an 18" BL on a JBL BP1200.1 amplifier Currently though, i'm looking at picking up another BP1200.1 for a total of 2. this means I would start changing around my subs then. Here's where i'll give you the info and you try to help me decide Limitations: Each BP puts out 1200 watts @ 2 ohms. I'll have two of them and they're not strappable so it'll be two subs i'm looking at. I have around 5.8 cubes of space to play with. Max sub size I can fit in terms of still being able to get the box in the trunk are 2 15's. I'm leaning more towards 12's though just because then i can actually give them a…

hmmm what could it possible be....? 2 TC3K's !!!!! top view, and a shot with the Orion 2500D, stupid UPS guy delivered the first sub, two diff. trucks...? WTF? 4 houses down the block???!?!?!?! good thing I saw him drive by and checked the awfully familiar looking sub crate box, with my name and address on it!!! anyway seems like things are finally starting to roll. Next, new 2-way alarm, tint.... then alt, wires... ect. cant wait!

Ok, so far ive gotten a answer from excessive amperage for my saturn alt. The largest bolt on they can make me will be 200 amps. Will this 200 amp alt be enough for me daily pounding my KX2500.1? I need to know soon so i can go ahead and make a choice. How is excessive amperages quality? Thanks in advance! Chris McDonald

I don't know how many of you know much about Thilo Stampler, TC Sounds, and Audiopulse. I recently visited thier forum(which I do on occasion) and was amazed by what a sad collection of wannabe-ghetto trash that has infested the site. You have people posting other people criminal records, "authorized dealers" spouting profanity, and the same 3-5 people posting anything anywhere they can generally bad-mouthing anyone with anything decent or intelligent to say. I feel bad for Thilo because unfortunately THIS is his public face. http://www.audiopulse.com/forums/index.php?showtopic=102

it's old but will it do the job? considering that it's free? click here

Of these two wires which one do you think is better? It's gonna be used to attach the front battery to the back battery. Knukonceptz or WeldingSupply Your Thoughts are appreciated, Yang

ok here you go I have two 12" Power Acoustik Mofo on a Ma Audio HK2000d the box is h 17" w 40" d 20.5. Now this is the space I have to work with h 21" w 46.5 d 22-28". Pease help with a box dimension for 18". I am looking at the Lms, fi and re subs. I would to set up spl with good clean sound. I have pictures will post later of the back of the truck. I need some advice on what subs to get and box dimension. Well I'm looking for spl really and no I don't have a buget as of yet what do you suggest. I was looking at the fi 18" re xxx18" and the LMS ULTRA 18". I am upgrading to two alternators and about 4 HC2400 and two yellow top under the hood, 2 SAZ_3000d to put on what e…

Ok, so I've done a lot in car audio, and have used a dmm to set gains before, but it was a cheap one from radio shack and i don't feel it was really worth crap even using. Never blown any speakers, but also know I've never had a perfectly correctly set gain on an amp. I just do it by "feel", "sound" and performance. natural abilities you may say, complete crap you may even say! lol but hey it's worked so far but i'm tired of trusting myself. What oscilloscope has anyone used? know of? how much? where? and what will do the trick/be best for setting gains? Thanks in advance i'm very interested!

So woke up this am 4 work to find my back window busted out, tailgate left open... and my subs gone!!!! didn't hear a damn thing... and I'm only 20 feet away or so from my truck. I'm planning on a new sub build anyway.... but damn...WTF? So sick of this crap... So it appears that I have a need for a two way alarm, any suggestions...? local audio place suggested a compustar, and wants 800$ to install it... remote start, glass break, 2nd horn...the works... I don't really care to put it in myself, but I might if it saves me some $, and is not tooo complicated. IDK... really want to catch these little F'rs.....

when designing a setup, when is it required to have more than 1 battery in the vehicle? If you have an alt capable of supplying the entire demand of current, let's say for a sundown 3000d, would you not need any extra batteries? Extra batteries are more like a voltage stabilizer while the vehicle is running, correct?

I was at my local shop today. Now, this shop is pretty popular around town. It's a small shop but a lot of 1st and 2nd place bass race and spl comp guys come out of this shop and compete at Carl Casper. There show room is flooded with trophies right now so you would think that they have a LOT of info in the audio world. While i am researching for the best subs that would meet my application, i was just curious as to what they would suggest me. They sell off the top of my head - Alpine, Soundstream, Powerbass, JBL and a couple others but nothin bigger than them that i remember. Anyways, i asked the guy if he could recommend a 10" sub for a ported box that would do well …

Alright considering pickin up another sundown 3000, and it got me thinking of bigger subs. Anyways, how does subs up port back work in a trunk car? I have 2 15s now, and considering 2 18s, but the subs would have to be facing up for this to work.

i am thinking about getting speaker replacements for my oem door speakers. i got a 96 honda accord coupe. these are the two i am looking at right now: ALPINE SPS-600 6-1/2" 2-WAY 240W and KICKER KS60 6 1/2" 2-WAY 195W. which one is better and maybe if someone else has a better set tell me. these two are only 10 dollars apart on ebay. they sell for around 50 shipped.

Hey guys, I'm really new to car stereo and need some help. I need all the wire, fuses and distro's for my install. I have a couple sundown amps, the 100.4 and the 1000d. For speakers I have a set of components and an Fi Q sub. I'm also looking to upgrade the big three and add a 2nd battery. What do I need to complete the install? I'm looking to purchase this stuff from knukoncepts. Thanks in advance for the help guys. p.s. The install is in a bmw so the stock batt is already in the trunk.

Hey so im about to start my latest project now that i have the money to play with, i just wont be eating until my system is in which is ok, but i am lookin at 2 Btl 12s bout 1500w a peice, so im going to need an alt. right? problem is im having a hard time finding one to fit my car...if anyone can help...and i already have a yellowtop bat. should i get another?

OK, i've been doin research on this and i can't get a hold of excessive amperage or Iraggi so maybe someone on here may know. I had planned on running a Lanzar 6000D with an Alpine PDX 4.150 300A iraggi alt with HC1800 and HC2400. Well, i've been doin some research on alts and it said once you reach 300A alt case size, it is extremely large. In order to have adequate cooling, they are normalls about 12" wide by 18" long! There is no way that could fit in there without doin some extensive re-running of the AC lines, but Iraggi makes alts this high which is odd. I drive a 2007 Scion tC by the way, 141hp dyno-ed stock auto, 161hp at the crank. Ok, it is also true that for …

does anyone have experience building this type of box? well for the time being im gonna use one atlas and figured since i've allways wanted to try this box design heres my chance. this is what i have so far. max dimensions 14-h 37-w 20-d so around 4.7cf, ok now i was gonna make chamber A 14x26x20 so 3.2cf and chamber B 14x11x20 so 1.2cf. now using one 4inch port 15 inchs long chamber a would tune to roughly 25hz and chamber b would tune to roughly 43hz. so how would this do? i tried to stick as close as possible to the 1/3 rule. also tuning that low will i lose my upper end response, like in the 60+hz range?

I want to test the cranking amps of my batteries... Does anyone know what equipment i can buy to do that?

I have a 2006 Toyota Corolla Type S and I was wondering if any of you have the same car and have a system in it or have seen a system in a Corolla Type S? I need some ideas on setups. Right now I have a Batcap 800 in the trunk along with Dynamat in the trunk and under and on top of the rear deck, a JBL GTO 1200.1 II amp powering 2 Orion HP 12s sealed in 1.2 cubes each. So far I'm upgrading my amp to a Sundown Audio SAZ-1500D and upgrade my Batcap to a solenoid and a Stinger SP1000 battery. I already have a 70 amp alternator so I don't feel the need to upgrade my electrical system. As for subs I don't know yet. So far I may want a pair of SS RL-p 12s sealed in 1.35 c…

I have a Ford Ranger Super cab and over the past 5 or 6 years I've owned two Shivas. I have always powered them with the same amp I used for SPL...MTX Thunder 6500D in parallel for a two ohm load (rated on the 'paper' at 402 w/rms at 4ohms and 611 w/rms at 2 ohm).The first one I had in a downfiring box in the center of the extended cab (over the hump). The most current one I had in a really small box (built to take up less room). I never had problems with the downfiring one, even though my little cousin once pushed the dust cap almost completely in...and then I had air leaks so I permanently sealed it in the box...hey, it was already ugly. The one I have now though, tends…

Ive heard the exacts but never the SPL components. They are older 2 ohm components. Anyone here ever hear a set? I'm thinking of picking some up.

Hi guys, I'm new at this. Not really sure how to post. But here goes. I am planning to to connect up 2 amps. A 300w mono amp to 10inch Sub & a 4ch 640w(max out put) to 2 front splits and 2 rear speakers. I am gonna run a 4 gauge from battery to a distribution block and then run 2x 8 guage to the amps. am i using the right gauges? i was also thinking of running a 1 farad cap from the distribution block aswell. My plan is 3x 8guage from distribution block. 2 to the amps and 1 to the cap, is this the right way to wire it up?Also my friend told me that it is not necessary to pre charge the cap. Is this true? Coz i have read some forums and they say to charge it prior to …
