Just out of curiousity, for those that are running batteries in the trunk, how many are running them without some kind of isolator? Are you seeing any issues? For those that are running an isolator, what are you running and where can you find them? What kind would you recommend, if any? I am thinking of running a Yellow Top in the trunk, or possibly a Kinetik. If I went with Kinetik, which battery do you recommend (besides the 2400 which I think would be a little extreme for a daily driver, but maybe not)? Thanks in advance.

Ok. I plan on putting 2 15" orion hcca subs in my car and would like to know a few things. I have 2 orion 25001d class amps for each and want to put only 2000 watts into each. So how many amps does my alternator needs to be and do i need more than one? And whats the best type of audio battery to use for under the hood and in the trunk? Thanks.

cause I dont want to but another rca cable NOW when im just going to get a couple inst. kits later down the line. I have my my 4channel amp running only the fronts right now with a rca cable and no inputs to the rear soooo its ok if I hook up all the wiring to the high input harness and leave out the fronts input?

What do u guys thinks about Us Amps XT-4000d? Im thinking about buying it to power my Fi BTL 12". Good or bad choice?

I'm about to purchase an amp for my ssa dcon and was wondering if a 12dB/octave slope would be sufficient on the low pass filter. I heard many people having a 24dB/octave slope and keeping it that way for their subs. My high pass filter is 12dB by the way. Any thoughts??

Hey guys I was just wondering what what ppl would choose! either 2 - batcap 2000 bnib or 1 XS d5100 and 1 xs d3100 bnib The batcaps will be about $536shipped The xs will be about $650shipped. The price isn't a factor to me i am just wondering which would be a better pick? my car audio right now is 2krms and in the future i wnat to push 4-5krms thanks for your time and suggestions Kenneth

hey guys if you could get one of these 2 amps for the same price which would you go with? kicker zx 2500.1 2500 watts birth sheet around 2700 watts us amps md.3d 2000 watts again same price

A buddy of mine has an Autotek Super Sport 1500.1. He is willing to sell it to me, but hasn't named a price yet. Are these amps good quality? Will it be too much for a single 15" FI BL? and are they overrated?

i am currently running a power bass XAX-2160FD 2ch x 100rms at 4 ohms and a percision power BK1300.1D that is 1300rms at 1 ohm. i have just the stock alternator which i believe is 70a. and also the stock battery. if i was going to buy a single battery or possibly 2 batterys what size should i get and what brand?

I'm planning on using some exotic wiring on being able to switch from 2ohm to 0.5ohm for competition via a switch so i do not have to rewire for an hour at every show. I see some copper made 80A relays. What i want to know is this, here is my scenario- Maximum burping current draw can be up to 85A AC. So i opted to use 2 80A relays per speaker in parallel for 160A of heat dissipation. Since Relays only use 10AWG quick disconnects, will quick disconnects be sufficient enough for this wiring? I plan on running modded inserts for 4awg wiring off each terminal of sub to a junction block. Then from there, 10awg to each relay pin, output to another junction box of 8…

it says 4kwatts. I found one that a guy has that he says is brand new. I can't find much out about them. Is this thing legit!? 4000x1@1ohm at 13.8v? I'll swipe it up if it is.

Ok so I'm staring to piece together and figure out what I need for my electrical pieces.. I will have a second battery in the rear. running two amps. Sub amp -T1500-1bdCP Front Stage amp is undecided at the moment. I have 1/0 Gauge OFC running to the back. probably ~15ft run. My plan is. Battery up front + (in line fuse)>>>>> (inline fuse) Battery Rear Positive + Ground up front will be left alone. Ground in the rear will be placed in the factory installed Ground fused to the body in the trunk. For the amps.... Running from rear battery ----- Short zero gauge OFC to a fused distribution block >>>>From the fused …

Well Me and the wife are moved into the house and I am happy with my new job---$5500 a month ain't bad . Hope everything is good with all the old school guys here. need anything just ask----i will try to be here more. Dave Edwards

Hey all. I'm at a loss right now. I'm preparing for a build replacing my subwoofer. I will be using around 2500 watts of bass plus 250 watts of highs. I'll have one battery, but I rarely play the system with the car off. Anyways... Nathan (from Excessive Amperage) seems like a great guy and super nice, but I'll be paying $25 more for 20A less. The Power Bastards alt is 220A and the Excessive alt is 200A. Any recommendations? Comments/experience on build quality? Both come with an overdrive pully and a one year warranty. Thanks.

I purchased about 15ft of Kicker Hyperflex 0 gauge to do the BIG 3 and the wire was MUCH bigger than expected. I had never dealt with 0 gague wire up until this point. I attempted the install with the wire but had difficulty due to its large size a tightness of my engine bay in addition to the awkward location of my alternator ('08 Altima 3.5SE). So I was just curious to know if using 4 gauge or 2 gauge wire would be sufficient since it will still be at least twice the size of stock? It will be 100% OFC, none of that aluminum clad stuff. Background info on my system is a Sundown SAE-1000D powering a 12" Havoc and a 4-channel Kenwood eXcelon powering my Ininity Kappa c…

Ive got a 105a alt and big 3 done also have a xs3400 under hood and a xs3100 on order, what else do i need to run a 3000w sub amp and a 400w high amp. Im guessing a larger alt . anyone that has ran similar or can give me help, thnx in advance

Anyone have any idea what could be causing this?

So my questions are what the difference? Aren't they the same since they are made by the same company? If not which is better and why?

hello, i was wondering if anyone knows a place where i can have a alternator re-builtfor a good price? its off my 1995 4.0 ford ranger (stock 95amps) im running a MTX 1501D (birthsheet says 1844 watts)amp and 1 12" orion hcca (2000rms/4000peak). the alternator is in perfect working condition right now, but its not enough for my amp. its starving for more power lol any helpp is appreciated!

Hey guys, just trying to decide between 2 headunits. Both have the features I want. iPod connection, Hi-Volt Pre-outs, 3.5mm input, USB, nice display, basic EQ controls. Ease of use is a priority for me as well. Both of them are right in the budget I was thinking. I dont really care about HD/Sat Radio, or Bluetooth. Kenwood X794 Pioneer P7200HD I know some Pioneer's have the weird ground noise that pops up sometimes, so that scares me a little. But I love the fact that the USB and 3.5mm jack is on the front. That is a big thing for me. I would just like your opinions on which one would be the better HU, if either is better. Thanks guys.

Like the title suggests, would it be practical to build a tube amplifier from scratch for a subwoofer? i need between 20-40w power @ 25hz 20w is acceptable but the more the better. Looks and size don't matter. Budget is $150

I'm looking for a nice 2 channel amp to power my new IA components. I was browsing and found a soundstream rubicon 2 channel that Puts out 130x2 at 4 ohms and 225x2 at 2 ohms. What do you guys think? Are they decent amps? I found one for like 135. Any insight would help.

I was always told to go for the highest number, but i cant tell any difference in amps with high numbers verses those with low numbers?

So I got my kinetik hc1400 and installed it today, and then tonight my dad was like did you get a new alt too?.. I was like what omg?!? you told me not to invest in one in this car.. And he was like well I didn't know you were going to buy more batts, he's like you seem to need a lot of power so you might as well just get an alt.. I was like omg yay, SO.. Now I figure since he said I should get one, that gives me a good excuse to finally buy 1 I have dreamed of getting one for 2 years. So Im going to save up for one now but need help first, Alright.. Down to the point, I have no idea how many amps I need the alt to do for my system and I need a good alt because I don't …

How much wire should i purchase from knukonceptz for the big 3? and should i get the 0 gauge or will the 4 gauge be just as good? I have a 12" fi bl on a sundown saz 1500d in a 2 cuft box tuned to 35.5hz. thanks
