Amplifiers / Head Units / Processors / Electrical

so i got an offer ona kinetic hc2400 for 200. sounds like a good deal to me.... but i heard if you plan on running a H.O. alternator it will kill the kinetic batteries. Is this true? I wont know if i even need an alt untill i get the battery installed.

Is it possible for me to run my back door speakers directly off the head unit if I'm already using the rear RCAs for my front stage? I know some people don't like the rear speaker thing, but I have people in my truck all the time, plus I like it that way.

I currently have a stock alt thats 70amps... but im putting in a 1300rms amp and a 70rms 2channel... i was wondering if i could get a cheap alt so i wouldnt have to worry about my voltage. I have all stock electrical, and stock battery no big 3... big 3 is going to happen very soon. But after that id like to upgrade alt... how much would this cost me for a 06 tundra. V8 4.7L

I have a Mark Antony Gspot GS754S. I can't find any information on it! Can anyone help me? Any information would be appreciated!

Hey guys, I'm in the process of building a system for my Infiniti G35 coupe and I'm trying to figure out which amp to get. Here's what I'm getting: Front components: Focal 165 K2P's, 100W RMS Rear Midbass/Midrange: Diamond Hex S6.0mx3 150W RMS, or Infinity Kappa 62.7i's, 75W RMS (Haven't decided if I want full range or not in the back) The amps I'm looking at are: Audison VRx 4.300 4x110W, $1300 Audison VRx 2.150 for the fronts, and run the rears off the HU 2x110W, $860 Audison LRx 4.300, 4x65W, $640 Focal 4x75W $620 Audison LRx 2.250 2x110W, $525 Diamond 6700.4 4x110W, $525 Focal 2x75W $420 I would love to get the Audison VRx 4.300 and be done with it, but it takes a lar…

I'm trying to hook up my amp/subs to my factory bose radio in my 91 Legend. I've got an ssa dcon 10", alpine mrp-m350, knukonceptz 8-gauge wiring kit, and pac soem-t speaker to rca converter. I've tapped the rear speakers correctly and cannot get the amp to power on at all! I've tried different ground points. I'm connecting the blue wire from the pac loc converter to my amps remote connector b/c the pac says that is built in remote. The yellow wire which teh pac says to connect to a 12v constant source is connected to my bose amp power line from the headunit. Do I need to run a seperate remote line or find a different 12v source? I'de just buy a whole new headunit, but m…

I just spun myself out on this, I feel like I know the answer but fuck it If i'm running an amp that draws 400a rms, and I have a 200a alt, a g31 under the hood 4/0 to the rear bank, and 6 g31's in the rear, I fuse appropriate for the wire always, not the peak rating of my alternator yes? something like, 300a for 4/0 iirc. If I already plug up the bank and charge it fairly often (once a week), no real concern for such a small alt supporting that bank, correct?

Does anyone have any experience with the 2003 line up of Rockford Fosgate punch amps? I'm considering picking up a Punch 150 "25 to life" amp to go along with my Punch 600.4. I'm wondering if it would be better to go with this amp or to stick with the older style 500.2 that I can get a bit cheaper.

all of a suddened my voltage gauge went down 1 and i checked every fuse and i put the meter right on the alternator it read 14.1 same as the gauge any ideas what may of happened?

Im getting Alpine Type‑R SPR‑60C 2‑way Speakers. rated at 4 ohms Going to be using an amplifier that can output at least 100 RMS each channel. up to around 125 RMS per channel. My car is a 2013 hyundai elantra coupe. I tried asking dealership if they knew the gauge of the factory speaker wire. or how to figure it out, in some manual or booklet. they said theres really no way to know, unless u measure or look at the wire itself. I tried looked at youtube videos or other sources online and couldnt find anything specifying the gauge of the factory speaker wire. Im assuming its between 18-22 gauge wire? I heard that something such as 20 gauge wir…

My lights don't dim or anything, maybe slightly if i crank it up. but its an 05 Civic, stock alt and battery...is there still any concerns i should be aware of? my amps: JLA 400/4 (using 75x2 currently) class a/b MTX 1501d (using about 1400 watts, 1.33ohm load) class d 4 guage power. Overall, system seems fine, nothing cutting out..etc. The OEM alt is a Mitsubishi, no idea how many amps it pushes but i'd be suprised if its over 100a. if lights don't dim, is it ok?

i was thinkin i wanted to get a 3000-3500 watt amp for 2 15" BL's but i just thought to myself that im not goin to compete with them, so is having the extra 250-450 watts really worth it??

y must everything not work for me =( .... i installed an excessive amperage alt about a month ago and it was not putting out anywhere its intended amount ... it would charge at only 14.1 and voltage drops would be incredible (into the 10s) ... no check charging system came on ... i decided to buy an iraggi to replace the ea alternator ... it still charges but only to 13.9 and now i am getting worse voltage drops and now the check charging system light comes on ... the pulley is smaller and also making a high pitch turning sound that i did not heard before in the ea ... i checked all my wires and it seems like everything is going where it is supposed to go ... the only th…

so i was sayin how the sub was making a knocking sound(bottoming out). so i decided to perform an experiment. i setup a -6db 50hz test tone put my radio at volume 35(70%) and i tuned the gain to put out 31.62 volts, which is 1000 watts. next i put in the removed the test tone cd and put the song that made the knocking sound in. looking at the volt meter some parts of the song would jump to over 40volts thats like 1600 watts, now i see why the sub was knocking, obviously that is a clipped signal. why is this happening? if i set my amp with a DMM with a test tone why am i getting a huge signal when i play a song. doesnt make sense and also makes the DMM method for setting g…

I just ordered a 1200rms amp from Hifonics, then, on sale I found another hifonics amp of the same class and everything on sale for the same price, but its 1700rms! The 2 subs im running will take 400-500rms each, so I know the amp is overpowered, but should I cancel my order and get the 1700rms??? I wont lose anything, I just need to know if the amp is too powerful? I would like to save the amp for a future more powerful setup. I have a 2000 mustang, and I only play music while the car is turned on, will the 1700 amp be too much to start my car? or will I notice any difference in power even if I keep everything turned down to only be pushing about 800-1000rms??? Pleas…

Ok so I'm running two sundown sa12's vented at 38hz 2.0 cb per sub on a saz 1200d whats probably the lowest I could safely run my ssf?

I have an ED 13Ov.2 that has just sat in my closet for a couple years. I just ordered a Nine.1 for it only to realize that they are on back order for who knows how long. The sub is a dual 2 so what is another nice amp putting out 600 or more RMS at 1 ohm for around 200?? Thanks in advance

I'm working my Audioque 4x90 to death. I need a big 2 channel to temporarily run my 2 SA-12's. The only thing I come across that really catches my interest are Rockford's. The New P500-2, older P550.2 and T3002 are serious dopeness. I'm not worried about a subsonic because they're sealed for the time being. I don't mind not being able to give them 750-800 per but I do want to give them atleast 250 each. I was looking at the Sundown 125.2 but I don't know just how much it does at 4ohm bridged. Oh and I'm not worried about the money I'm spending on this amp and spent on the sealed box cuz they'll both go into my gf's car when she gets it. When I do get a mono it'll be somew…

I read some where that all alpine head units have crossovers that cut off bass at 30hz so they want allow you to hit the low lows. Is this true or just internet BS?

Someone in my area is selling one, and I'm just wondering if anyone knows anything about em'. It's rated 800 @ 1 ohm, but I'm not too sure haha

Alright, so sold off everything from old substage, well actually sold half of it, other half got stolen. Anyway will be running 2 1500d's on 3 SA-12's, and backing them on the electrical side will be a kinetik hc2000, hc1400, and optima blue top under the hood. right now alty is a small upgraded 120a. I am saving up for a real nice 200 a 240 peak custom valeo from ohio generator. Now the real question is this. I want to charge batteries to 15volts. right now with the optima, and two kinetiks that is a total of 4500 battery amps and 162 ah from kinetiks and I believe 55 ah on the optima blue top so 217ah total. I do plan on adding another hc2000 and hc1400 on oth…

After Long Time Of Looking Through 50+ threads using the Search bar and going through the build logs i still was unable to find what i was looking for Im tring to find pictures of amp racks where one amp is on top of the other. I Remember seeing one in an SUV but cant find it. Kinda looks like this...

I was telling my dad how i am going to buy another battery for my truck soon, for audio, and he said that he thinks putting the battery in the cab is illegal? I'm not sure why it would be and i have seen almost everyone on here put them in the cab. Is it illegal? I live in Texas if that helps.

Ok, I have decided the XXX, huge amp, heavy optima yellow top 31 series, and massive box is too much for what I need it for. I am selling everything except the Rainbows and my HU to Jamie's cousin. Here is what the next system will be: 2 RL-i 8's sealed in a movable box Rainbows on a 150x2 amp (that seems to be the most power they can take) A matching amp for the rl-i's (around 700 watts) Audiocontrol EQT's and 4XS I would also like to be able to stay in the running for USACi 0-600 sq class. I can get the JBL's for about 550-600 if my eBay powerseller pricematch goes through on SD. I can get the Kickers for around 750-800 I think. I already have a PA VX3002, and anoth…
