power

So I did a clamp test on my SIA 3500 amp and I'm getting only 1200 watts put of it so now I need to get a alternator. Any suggestions of brand I'm looking for a 350-400 amp alternator. 2012 nissan altima sr

So I have 2 sundown uv2 12s the rated power is 1750 RMS. People are recommending putting a 5k amp to the pair and a couple recommended putting 8k amp to the pair. I'm just confused how to know what amp to get

Ok guys, where and what brand of 1/0 you guys using and buying from? I'm looking for something ofc and that doesn't break the bank.

If I have sundown 2 12 Uv2 what amp should I use? There rated at 1750 watts each but when I talk to a sundown tech they said they could the SFB 5000.D witch is a 5000 watt amp so it would be pushing each sub about 2500 each

So I have a XS SB500.34 power bank/battery hooked up for my audio system it has max power is 4000 watts so does that mean I don't need to upgrade my alternator unless I go over the 4000 watts or what does that actually mean and when should I upgrade my alternator. I'm trying to learn more about...

First of all, Hello everyone. Thanks for having me. this is my first question here. I want to run 3/ 8" subs that need atleast 200 watts each. And 2/ 5.25 rear deck speakers requiring atleast 80watts a peice. I'm not familiar with mono I know its single, and you can parallel and all that, but...

Say I have an amp that has X amount of power. The speakers can't actually handle that power but I still want to use the amp. How is an amp properly adjusted to limit the output to the speaker's capabilities?

I'm building a portable speaker with car auto parts, I have a 1000w amp for the full range and a 2000w for the 4 subs. The last power supply I had for it was a 12v 40A and I blew it up because it couldn't handle it. I'm wondering what I need to get In order to power the thing.

I recently recieved this sub/amp setup from my uncle for my birthday. 600W MegaVox Competition Amp and 2 x 10" Marathon subs in a Marathon competition sub box. I have a 200W power supply that I used to test them as they are 20-25 years old. When connected to the 200W (12V @ 18A) power supply the...

The system I’m building is, in comparison to some I’ve seen, mediocre, but I want it to perform flawlessly and rather maintenance free. Here is what I’m currently running. This is a 2002 Cadillac Escalade base, not EXT HU: Alpine ilx-207(4v pre-outs) powered via vehicle ignition. Was using all 6...

Hello hello, So, I recently purchased a new radio for my 2007 Jeep Grand Cherokee Laredo. I bought the wiring harness and antenna adapter, and went to hook everything up, but the radio didn't come on. I checked the wires with a multimeter and my ground and constant wires seem to be fine...

I was planning of doing something like this video so that my stereo does not power off and loose bluetooth connection when the starter kicks. This will only power the reciever, and will not run any amplifiers. But I do not know if it is 100% safe or if pre made kits are available for this...

Hi guys, new here, sorry if asking the same question. Please help! (Speakers) 2 12inch L7S in kicker ported box wired at 2 ohm. (Amplifier) kxa 1600.1 mono Is this enough to get that rumbling bass? I 1st installed it and i know it has potential. But my 1st time with the kicker brand. I feel...

I am planning out my install and want to run a single power cable from the battery to the trunk, then split into two 4 gauge cables to power a sub amp and a speaker amp. Each are rated for 4 gauge power. My thought is to use a larger fuse at the battery and then 2 individual fuses at the split...

This question may be quite straight forward, but I cannot find an answer anywhere. I am new to this forum but I found the formula to ballpark estimate my total amperage. I do not understand one part. When you calculate this, do you add up the total RMS of the amplifier AND the subwoofers it will...

I am new to car audio , anyway , the taramps HD3k has a 1ohm and a 2ohm version , does this mean 1/2ohm stable or does this mean it will produce 3k at 1/2ohms?

Putting together an old skool system for my summer toy. Currently have 2 OG rf amps, looking for a punch power 501bd and hx2 10" { d2 or d4 doesn't matter to complete it}. I would be interested in a few different amps though. 551s,500a2,p600.1bd, if its fairly old school 2 channel or mono and...

Hi people, first post here and I'm building my first system. I will be running an Orion XTR-2500.1Dz amp powering an HCCA 12" black coil sub.

Hi! I recently removed my subs in my ford escape because I wanted to get my cargo room back and am forced to use a shallow 8" subwoofer for the factory enclosure. So I bought the MB Quart DS1-204. It's a 200w rms and 400w max sub. Anyway! The sub channel on the amp I have in the car says...

Last night everything was working fine, sounding like it should and this morning i woke up and had no sound comeing from my speakers. I get power to my radio, and it is showing that its playing but its not, im not even getting static. Pulled over, popped my trunk, and the amp isnt even powered...

Ok so i have a 15" 3600W pyle subwoofer hooked up to a 1000W amp. I just put this in a few days ago and ive noticed that when i first turn my music on, the sub hits but it definitely doesnt hit like it should. The second thing ive noticed is that after playing my music for about 15 minutes the...

Ok, so I crunched some numbers today after cutting holes. I have enough wire and lugs to do sixteen runs of power and another 16 of ground with my Sky High 2/0 OFC. Now, I'm not completely stupid. That's wayyyyy overkill for just about anything. My question for yall' is how many runs you...

I'm a teenager in high school with a cheap setup in my car. I realize my components are low end and bad but don't try and bash me too hard. Anyways, I have a 4 channel 1000w what amp... which is 90w RMS a channel. Currently I am running 2 6x9s, which are 60w rms each, on individual channels...

My question is if my car can handle my amplifier and if not why do I need so it can? I've been putting a sound system together piece by piece for about 4 weeks now I bought a 1600 watt massive audio amp and 2 1400 watt 12' pioneer champion series I'm currently waiting on the box to arrive and...

I have a pioneer GM-D8601. After hooking up, i turned the car to ACC and set the amp gains. Later when I turned the car all the way on to drive it out of my garage, the amp's power was way less. It sounded a lot quieter. I experimented and still can't find the issue. Occasionally with the car on...

Hey guys i'm just wondering if i plug a 300w inverter into the 12V outlet in my car will it kill my battery faster than a 140W inverter would? or does it only draw what it needs for the appliance plugged into it?

None of the "special" car audio batteries will work because the shipping for these are like the price of the battery itself (at least the places that I've seen). What exactly are the specs that I'm supposed to be looking at as far as voltage drop for the load of the amp? Are AGM's the only...

I need help on what speakers to buy! I have a 4 channel Kicker amp (650 RMS) powering a pair of 6.5's, 5.25's, and 2 dome tweeters. I'm thinking I need at least 100 watts RMS each speaker, but not sure what to get. I would ask the shop that did my complete install, but they assured me my focals...

Last week I ordered an optima red top for my car, it is scheduled to come in in another week. This morning on my way to work my cars battery died so later today i am going to buy another optima red top locally. Currently i only have a 90 amp stock alternator however in the near future I will be...

Thinking about running 3 obsidian audio 15's and was wondering how much power you guys think should be ran to them, since they are conservatively rated for 600 watts a piece?

Right now im running my JLw6V2 at 8 ohms on a Solid Audio F11D, Its receiving around 200rms. I was wondering if it the JL could handle being run at at 2 ohms for 760rms abouts? From what ive ready its been usually mixed advice and opinion so far on whether it would be wise to.
