Amplifiers / Head Units / Processors / Electrical

Just got in my new head unit, for the vehicle I dont even have yet! I sold the scion, but wont be picking up the new ride for another week...Priorities!

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.

I'll be running a bi-amp setup in the near future. As of right now the amps will be: Memphis MC3004 (75x4 @ 4 ohms) Memphis ST or MC 1000D (600x1 @ 2 ohms) Part 1: I have never done a bi-amp setup and was curious about the power wire. If I run this through a fused distrubution block, do I need an in-line fuse between the positive battery terminal and distribution block, or will the individual fuses in the block suffice? Part 2: I figured up the current draw on both amps based on the sticky in this section. It looks like: MC3004 will be drawing 32.5A 1000D will be drawing 44A I am currently thinking that I will run a 0/1AWG wire from the battery to the distro block, th…

Ok, yesterday, I rearranged some things behind my head unit, which was working fine. I put everything back and the HU was working fine. After putting my dash back together I was planning on going to my friends apartment, but when I go to turn on the headlights a fuse blows and my dash lights cut out. I try replacing the fuse and when it blows again I check a few things and say screw it and go inside. CD player still works fine. Today I test things out better. I figured out that when the HU was not wired up the problem does not exist. When I plug the HU back in the fuse blows and such. As a matther of fact the voltage at the battery (all wires still connected) I get 56volt…

i have 2 powerbass XS-15D1v.2 and i was wondering if the powerbass xa3000d would be to much power for my subs? if so what could of amp should i use?

Well, my Avionixx 4ch died on me, so while I'm having it refurbed, I think I'm going to go ahead and upgrade. Right now I'm looking at an Eclipse E4000, it's rated at 100w x4 @ 4 ohm but the guy at a local shop says he thinks it does more like 85w...I believe him too. Anyway, does anyone have any opinions on their amps? I want this to last me a LONG time, not just a year like the Avionixx... http://www.smartcart.com/alneds/cgi/displa...item_num=EA4000 The shop is charging 320~325 out the door or I could get it 225 shipped off egay. Anyhow, opinions please! I want to purchase soon (like today)... I WAS gonna go with a PG Xenon 100x4 but it's too big.

So I get to the alt shop and talk to the guy. We test my alt with a clamp meter and a volt meter. Here is the results. No accesories 12.7@600rpm 13.9@700rpm 14.5@900+rpm Acc on (no stereo, just lights and A/C) 11.8@600rpm 13.6@700rpm 14.5@900+rpm Now here is the part that gets me. The alt shop told me that I do not need a smaller pully. Shop: "You need another battery and an isolator." Me: Why??? Shop: You have plenty of amps but low voltage. Me: OK, another battery run by itself is going to help? Shop: Sure it will... Me: please explain this to me? Shop: the second battery will no longer be tied to any of the other accories in your truck. Me: thats fine and all, b…

i bought a new zed audio amp at the beginning of may. zed was giving away free refurbished amps with a new amp purchase. i got a free us acoustics amp. i bench tested the amp as soon as i received it and it played music fine. i put it back in a box and never installed it. on june 2nd it sold on ebay for $160. the guy left me good feedback on june 12th. on august 7th the guy PMs me on sounddomain and says that he finally got around to hooking the amp up and it blows his power wire fuse (the amp doesnt have onboard fuses). i respond immediately, telling him how i tested it. i asked him to measure the resistance of the inputs with a dmm, and look at the circuit board for a…

For my birthday, my girlfriend bought me a brand spanking new Eclipse 5425 HU. I chose to install it because I was ripping everything out in order to lay down wiring for new speakers and amp. And I just really like doing that stuff myself. The problem is this... Sometimes the display and buttons don't light up and are inoperative. The stereo still plays, but you can only adjust the volume level and change stations. You cant insert or eject a cd, change any functions, or even tilt the screen. Other times every thing works just fine and dandy like it should. There doesn't seem to be any patern to when it does this. I have triple checked my wiring and made sure th…

I'm a little bit confused about how to wire the RCA's. They have basically 6 sets of preamp outputs with some labeled mid, highs but also some sets labeled positive and negative. The manual isn't too detailed about using the pro setup except to connect all of them. I am going to be running tweets and mids up front and mids in the back. Plus a sub(which it has 2 pairs of outputs to as well for some reason). I will post some pix if necessary. Thanks for any help you guys can provide. I'm trying to get this done tomorrow as i will be working til 10 pm tonight.

I have a factory system in my new Explorer and do not want to go through installing my cd player right now. I want to keep it all stock except unhook the 8"sub in the back, run the signal to my amp and have my two 15s back there. How would I do this?? Could I simply hook a LOC to the wires that went to the 8"?? Or would the power that is run through that be too much for an LOC, or does it even matter? Quick Quick with the help if you can please, going to try and get this done by tomorrow. Thanks much.

Hello ppl does anyone onwn this amp I want to purchase one from the net...How good is the sound quality ? I'll be using it on coxials speak. or can someone also recommend me an amp let's say about 50 rms per channel .... and budget around $150 thanks to all

I'm looking into the 8455, but Eclipse has the worst site in the world with little info. I'm wondering if the aux input is direct connection, or do you need an adapter like on Pioneer and Alpine? Also, anyone friends with any dealers that will ship to me? The local dealer here is horrible and I refuse to give them my business. Thanks!

right now my battery is grounded to the front of the drivers side head (which is aluminum) i get a bit of noise every now and again through the front speakers and probably inaudibly through the woofers. the passenger side head is grounded to the chassis, above the motor. its all 4 gauge. i'll get a better ground by grounding the battery directly to the chassis right? then i just leave the head grounded above the engine the way it is? i know it needs to be bare metal, but can i just ground it anywhere thats metal on the body of my car, or does it need to be directly to the frame?

i need an amp that is 600w rms @ 4 ohm. or anything that will power a 15" tempest nicely. dual 8 ohm sub. thanks!

well after a long and painful 8 months of design and thought----Pioneer P9 combo is what I have decided on. just letting you guys know----it shouldn't be too much long till I am dropping pics all over this forum of the install.

i put in my new 200 amp from the group buy at ca.com forums. when over 950 rpm or so, it is awesome, rarely ever drops from 13.5 volts and when it does, not under 13. (going by my dash gauge anyhow) under 950 though, the voltage will drop almost to the red, to around 9.. red is at 7.5 or 8. having the stereo up drops it almost another half volt. either way, that is way low voltage. i could just turn my idle rpm up to 950 but it would burn more gas, and i like the rumble of a healthy v8 idling around 700 rpm. i do not have my optima yellow top in yet, waiting on terminals. im using an old, cheap, autozone battery, with 4 gauge run to the back split into 2 8 gauge wires. …

has anybody heard of these amps, and if so what you think abou them http://www.lunaramplifiers.com/mainindex.html

i'm thinking of getting a second eD nine.1. they're 900 watts stable at 2 ohm, and 1200 at 1 ohm. if possible i'd like to run them both at one ohm, im pretty sure i have the electrical system for it. question is, if i wire a dual 4 ohm voice coil sub by itself to the amp its either at 4 or 2 ohms right? no way to get 1 ohm load from a single d4 woofer? could someone maybe give me a crash course in wiring? i think i would need d2 woofers to get 1 ohm from 1 speaker right?

Are alpine amps worth buying? are they good?

I saw a link that Ryan posted in the ihop for a Directed 1100d5 that does 75x4 at 4 ohms and 600x1 at 1 ohm on the sub channel. It doesn't say anything about bridging the amp, but I was wondering if the amp would work if I wired it to where the left side was on 2 channels of the amp and the right channel was on 2 channels of the amp. This would be kind of like bridging it, but running a wire in all 4 pieces. I think if I bridge it, it would put out too much power. Has anyone ever done this? It is sounding like it won't work or will be bad for the amp, but I am not sure.

i just hooked my system up, and every now and then, when i have it turned up, both my amps shut down, like the remote was coming undone at the deck. deck stays on and all, amps dont give me protect lights they just turn off for a few seconds and come back on (not always off for the same length of time) my electrical system is all stock, i believe its only a 105 amp alternator, 4 gauge wire back to the distributor, and 8 gauge to the amps. any ideas?

Most audio equipment dies for one simple reason. Most people push their equipment beyond its limits. Whether it is the amplifier, subwoofer or full range speakers, clipping is the number one cause of failure. To prevent clipping, use this tutorial. To figure out what voltage you should set the gains to, multiply the RMS power of the amplifiers output by the impedance of the speaker, then find the square root of that number. If you are using an amplifier that has an RMS rating of more than your speaker(s) can handle/rated for, then use the RMS rating of the speaker (instead of the RMS of the amplifier) to determine the voltage to set your amp to. This is also referred to a…
