Is hifonics a good way to go for amps?

Well guys---I read alot of forums and it looks as though ALOT of people are misinformed about the "basics" of car audio----I need your help----tell me a topic in which we can all give our input and see if we can come to learn more-----I personally am sick of seeing these "which sub or which amp" topics----it is called "learn then deside for yourself". I will talk in depth about all of the topics you want but I need a start----you guys from FXN.net know me pretty well to know I can talk for days about car audio. for the guys that don't know me---- http://www.fordexplorer.net/viewforum.php?f=10 Alot of the stickys are mine. Read and enjoy. Live and LEARN, Dave

I'm considering buying a used Avionixx AXA440.4 for around $100. Any opinions? They're rated at 85x4 W RMS @ 4 ohm but are supposed to put out around 100W. Any info would be great.

like the title says. i need a 2 channel amp that puts out 150 watts at 4ohms. any suggestions guys?

I'm running 1 Linear Power 5002iq to 1- 12" sub rated for 500 rms. Linear Power suggests a 60 amp fuse, 1 at the battery and 1 at the amp. The amp has 8 gauge power wire hardwired in to connect to. Do I need to run 4 gauge from the battery to a distribution block or can I get away with 8 gauge from the battery all the way back? Thanks

Changed from the Ppi Pc 4800 to the Ppi 300.4 i got this as a gift from my Friend Jeff

How many ampere's should 1/0 be fused to? im thinking 200a just to be safe because if my stock charging system exceeds that something is wrong.

Hello all, my set up is pretty basic..kenwood radio and eq, kicker 1200 mono class d amp for my jl 13w7 and kenwood 100x4 interior amp. Also I have a optima red top under the hood and a stinger battery in the trunk all ran with 0 gauge from and I did the big 3. I still have the stock 100 amp alt which im replacing with a 180 amp and also, I never play my system with the car not running. Right now my lights dim and at night when I press the gas pedal my lights get brighter, so will the new alt stop that? And whats the highest that I should have the gain on my sub amp? Thanks in advance for any help

So when I originally purchased my amp (1k5h 1ohm) it was the combo deal with my xcon d2 but I now will be running both xcons on it until I upgrade electrical and go bigger also got to save up the money My question is should I just wire it to 2 ohm load and have less watts per sub or wire it to .5 ohm and just keep an eye on it to make sure it don't over heat Don't want to ruin this amp it's been great and I would like to sell it in the future when I upgrade Thanks Logan

So in my electrical class my group and I are doing a project on MOSFET's and I will be bringing in some MOSFETS (blown and new) for some show and tell, then I wanted to bring in my amp (saz2000) and show that off but then I looked at the board and I was like umm maybe I should learn all the parts and how the amp works! so here is my amp's guts (i got the pic from another forum the saz2000 pre-sale one!) so here is what I understand (i hope i am not 100% wrong) on the far left and right sides those are the MOSFETS, the power supply are the 4 red coils, the caps are on the bottom center and top, the teal things I don't know (top center) the pre-amp is all that stuff at …

what is the pre amp voltage in deck do? what would be the difference between getting a 4 volt pre amp deck and a 5 volt pre amp?

Ive got a 15" SSD with the flatwind coil option. Just wanting to know what amp would be better, and if the audio que puts out more than 870 @ 2ohm

i got 2 RE HC 12s, i have em in a 6 cubed box tuned to 31 hz, wit a mtx 1501d powerin both. I think i hooked them up wrong or something, Cuz my rearview mirror dont even vibrate. and my friend can do that wit 500 watts. i used the wiring wizard at rockford fosgates site running it on 1/0 gauge wire http://www.rockfordfosgate.com/rftech/wiri...x=21&image.y=13. personally, i believe that i should have hooked each speaker to a different speaker output on my amp. Heres some pics ofwaht the outside of amp looks like. http://www.crutchfield.com/S-kNz22QCXzEr/c...&display=XL#Tab and, http://www.crutchfield.com/S-kNz22QCXzEr/c...&display=XL#Tab I dont no what phas…

Im looking to get one battery once i pick up my new car, i was reading some threads about the YT sucking after 1 year or so, i will be running a Hercules(2000x1) What would you guys recommend?

Im getting ready to install theese products in my 1991 Ford Explorer XLT and would like some advice whether these brands are any good at all and if not what else to get with the stuff I have already bought..ok.. this is what I've got Brand: Lanzar Vibe 248 1200 Watts Amp(for subs) Brand:Dual 12 Inch Subs In Bandpass Box Brand:Jensen A222HLX 250 Amp(for front stock speakers, possibley rear stock as well). Thanx beforehand, Morgan

i was reading the .5 wiring thread a while ago and somethin hit me that i'm curious about. The opti2000d by lanzar is the only amp they have that is 0.5ohm stable The Saz-1500d\3000d "used to" have 0.5 ohm warranty coverage until... well anyways. The opti2000d is 0.5 stable all day every day. Is this the case with SAZ amps as well or are they just lenient on below 1 ohm stability? The opti is the only class d amp i know of that is guaranteed to be stable at 0.5 ohms, so curious about this.

I see that quite a few people have these. These amps any good? SQ? Efficiency? And do they do their rated power?

Ok, so ive had my 8053 for about two months now and I am completely in love. so in love, I was telling my girlfriend the other night that if my truck ever caught on fire I would actually take the 8053 out before saving anything else...lol I wanna add XM to the truck, no need to try to get me to pick sirius they dont have Baseball. My dilema here is that my favorite team (Oakland A's) is on the West coast and I am on the East coast, that also kinda helps because I work the 11pm to 7am shift and I could bring the radio in with me and continue to listen. I am looking at getting the XM MYfi because I can take it everywhere I go. So I guess my question is what do I need to ho…

Anyone used this charger? http://www.impactbattery.com/brands/japlar-schauer/12-volt/schauer-12-volt-battery-charger-jac1212.html is under 100$ looks pretty promising. cant find any reviews online though.

i just heard something weird from a tech at Hifonics. the reason i am not getting sound is because i have "stereo input RCAs" or something of that nature not "mono" ones... so now i have to buy a splitter that will connect to one of my old RCA cables that will be split in to two for the two inputs on the amp... if that makes any sense.... i find this weird because on my old RF amp it has matching colors for each of my old RCA cables which made it so i didnt need to buy a splitter... is this normal? i thought it would be straight forward red to white but i guessed wrong...or so i hope!

ok so my stock harness is fudgeed....how do i know? i hooked up the stock deck.. and i attached a HONDA wiring harness to it and wired up my Eclipse, still no good.. so i decided to wire up the HU directly.. only problem now is i need a direct illumination wire, help plz?

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?

Ok so Im kinda stepping up a little bit on the whole sub scene and I kinda got over my head a little bit. I thought I would look to you guys for some guidance. I have bought 2 15" Orion HCCA's. I bought the dual 4 ohm version thinking Id just run 1 big amp. Well my noobness has bit me in the ass. I need a large amp as wasnt really thinking of the amp draw that this would present. So if I can get any suggestions on amp/batteries/alt that I may need I would owe a favor for sure. I know you guys get these questions all the time and I didnt want to be "this" guy but I really have no other choice. I want to learn this instead of just paying some shop to do it for me. …

I just built a box for my new fully loaded Fi BL 15. Specs: H:18" W:17.5" L:38".....Square port length: 4.5" Port length 2: 20.75"...with 3/4 MDF. Box is tuned to 33.14hz and the Box volume is 3.822cuft. Sound good? will it work?
