So we finally got some decent weather and have started with my install. I had ordered some knuconcepts 1/0 gauge and it arrived it mail today. I had installed all the sound deadener I had which wasn't enough. I decided to make the positive run with my wire that just so happen to arrive. I was able to complete run so it’s ready for next step. Now I am looking at the rest of my electrical and what I will need. I have 2 XS D3400 on their way. One of which I am thinking of using as my main car battery. (This was the battery recommended off of XS website for my vehicle.) the second will be for my audio system. I want to ensure I use the correct fusing for this install. I b…

Hello all, Would you mind giving wiring advice for my Pontiac G6? Here is what I currently have: 1 yellow top in engine bay, no rear battery yet. Big 3 done with knuconcept 1/0 1 run of power wire to trunk I am grounding off frame in trunk, but when I tested the impedance I got a low # (don't remember exact #) Standard alt I will be running 2 Xcons 12s D1, with most likely a BC3500. I have a BC2000 for now. These will be trunk mounted with fold down seats. I will be buying a amp for the component speakers, not sure what yet? This is a daily driver, so I want it to get as loud as possible while still sounding tight over a wide array of music. I mainly listen t…

So last night I sat down and made a small list of wiring and accessories I'll need to get my saz 3500d powered. I'll be running one battery upfront and two in the back. The extra 0 gauge is for the big 3...Any advice on better products or a cheaper source would be appreciated.. http://www.subtilisaudio.com/products/Stinger-SPD5203-Pro-Classic-ANL-0%7B47%7D4-Gauge-Inline-Fuse-Holder.html x 3 @ $35 - 3 fuse holders http://www.subtilisaudio.com/products/Tsunami-5-Pack-Gold-ANL-Fuses-%28Choose-Size%29.html x 1 - $8 - 5 300amp fuses http://www.subtilisaudio.com/products/Stinger-SHI2120-HPM-1-RCA-Cable-20FT.html x 2 - $24 - 20ft rcas http://www.subtilisaudio.com/products/Stinge…

I am a queer spammer.

I started this topic because I've seen some negative remarks around the internet about their products but not necessarily(sp) why. I personally own two Nine.1's and a Nine.4. I'm not trying to start anything in any way or any kind of fight or flaming, I just want to know why some people don't like them. I'm thinking of running new amps and I'm trying to decide if its worth it or keep what equipment i got. Personally I'm happy with them and thats what matters, but I just want to hear from other views. Mods- like i said I'm not trying to cause any problems just looking for the stereo community's thoughts. I'm sorry if this post is against any rule and please delete or lock …

Does anyone know how to figure out the resistance when i wire a dual 1 ohm sub to .5 ohm, and a dual 2 ohm sub to 4 ohms, and then wire those subs together in series?

About week ago while my truck was running and my music was playing my girlfriend opened my passenger door and my speakers started to hum. I seen the same problem with my friends amp "Foxmoto" and tried alot of things like changing my wiring, RCA's and my grounds about 5 or 6 times now and nothing seems to work. I have checked all the electrical and the readings are all normal. Any suggestions?

Hey everyone, I've got this irritating alternator whine ever since upgrading my front stage, hopefully someone can give me some insight. Here's my setup: 02 Lexus IS300 Alpine CDA-9856 MRX-M110 RE SE 12 *SPR-17s *PDX 4.150 *KX3 crossover The items marked with asterisks are new components to this install (owned them since ~07, sat in the closet for a while) and are where the noise is coming from somehow. I've searched extensively for resources to find anything I could do to fix this issue but to no avail. The most comprehensive guide I've found is at http://www.termpro.com/asp/pubs.asp?ID=121 but I've tried everything (new to me) that they suggest, bu…

I recently installed another amp and some 6x9's in my car along with my existing sub amplifier, I have some obnoxious engine noise going on now that wasn't there or noticable before the install. My power wire and RCA's are ran on seperate sides of the car, The amps do have a common chassis ground in the trunk. Is the engine noise because of the shared ground? If you need anyother info please let me know. Thanks for the help.

So i bought 2 15" fi btl's off a friend and i was wondering if a rf t2500bdcp amp would be ok for both subs at .5ohms? I dont compete and i play mostly spanish music...my electrical consist of a 270a alt and 3 xs3200 batts...all 0/2 gauge wire...

I have a 2003 mustang and I'm planning on buying an 12" Fi Q with the BP power option, a RF T1500-1, and a RF T600-4 to power the four corners. My car is 100% stock and i was wondering if my 105 Amp alternator and the big 3 fix would be enough to power all this. If not what should I do. Oh and why is it people prefer batteries to capacitors? Thanks, Matt *Edit* The alternator is 105-110 Amps. Not that it makes much of a difference...

What is the best entry level amp in the market today?... Obviously they will not match those high-end amp so lets not compare them... just want to know for consumer preference...

I have been looking around at equalizers and was wondering how Epic 160s worked as one? I have heard they aren't very accurate for metering so is it even worth getting or am I better getting something like a Clarion 746?

I was thinking about getting one of these (http://www.audiocontrol.com/14152/products/EPIC--160-In--dash-Car-Audio-Bass-Processor-and-160-dB-SPL-Display.html). Anyone have experience with them? I have always just used my headunit and the PAC LC1 to turn up my bass and it sounds fine but some people say it really does help improve your system's bass . I also heard that you really shouldn't use this product if you listen to bass enhanced music such as decaf/dj slow n throw/etc.. and thats mainly what I listen too. Do you all think it will improve my system if I mainly listen to the music stated above? Or do you think It wouldn't sound any different? What do you guys thi…

epicenter....... when/why do people use them..... are they a waste of money??

Does the epicenter help increase you spl or does it just act like a bass boost where it will just cause the amp to clip. Would it be a good idea to buy one if I mainly use an ipod?

Good evening people I need some info on the epicenters , like the ones from Audiocontrol . What exactly do they do ? Is it a great plus having one if it's free. thanks

I have a EPx2 Processor with the 28 band eq card and the control of the unit is great i was just wondering if anyone had one with the dsp card in it and if so if the could tell me the benifit of having the card. I love the unit I had saw a dsp card on ebay and was trying to see if i would be getting any more out of having the card in the processor or not.

Well, here is the deal: Ikesound is out of DEI 1100D5's, so when I returned mine because it wouldn't power up, they said that I can have store credit (haha), so I emailed them back and told them I want a refund. I am probably going to go with a pair of the US Amps IS series amps (IS 2200 and IS 4065). I will be splitting up the crossover on my 3 way rainbows to run the midrange and tweeter off of 2 channels and the midbass off of the other 2 channels of my amp. I have 2 long runs of rca's and 4 short pairs for what I previously planned on doing, so that is a factor. I also heard that it is bad for sq to have multiple processing devices, so that is why I am kind of wear…

whats the difference between a graphic eq and a parametric eq. also whats the advantages and disadvantages or each

so i feel that i am now at the point of buying an EQ. my questions are: i have tweeters, mids, bass, and i might have a set of mid bass coming up. should i buy a 3 way EQ or a 4 way? how many channels is enough? id think i want at least 30 channels to eq from no? the more the better? what is the difference between a 1/3, 1/2, and 1 octave response? how can i tell if my deck is clipping the RCA signal or if a processor is clipping? to be clear i am not looking for some worthless 40hz or max volume one time measurement but i want a way to tell at a glance if i am clipping with a wide range of songs and volume configurations. i currently have a KX3 xover, would the …

I had one question and maybe a manufacturer can answer this, why is it that eq's have boost circuits instead of just reducing the overpowering frequencies? If your boost the frequency voltage, doesn't that create an undesireable risk of clipping in the system?

Can anyone recommend a good working EQ. I used to have an old PPI unit with my old set up, but I don't think it works anymore. I plan to get a SS RL-p 12, either the USAmps 2080 or 2100, CDT CL-62 and I already have a Diamond Audio 1200.1 for the sub. Are their any that I should stay away from?

Im thinking about getting a clarion eq., and I was Wondering if its worth the trouble? I've saw a lot of installs and I don't see to many running them.

i recently got a crossfire CFQ5.2 equalizer, but it didnt come with a munual or anything to tell you how to hook it up. can some one help me?
