Will these really replace a battery?

I realize there will be hate to follow, but whatever it's no big. I'm very happy with it.

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…

will i saw a car with a pc in it over the weekend and i want to do it but don't know it it is going to work better the a head unit so if have done this or if you know if i can do a sq build with it

My deck is rated at 4 volt preamp but when I measured it I get 4.1 volts at maximum volume on my subwoofer RCA and 0.7 volt on my front and rear. The deck manual States 4 volt at 10 percent Distortion so my question is should I pick up a 3-way line driver, cap the deck volume at three quarters, and use the line driver to boost the one volt and 3 volt signal up to 6 volt?

I picked up a 125.4D from my repair tech..never heard one but he said it puts out more than rated and sounds pretty clean. I will soon find out. Just curious the deal on the amps and company., Most of what I have seen is not that favorable but I dont know if that is the owner or the product. my tech is a engineer and he reverse engineered the amp and had good things to say about it. better quality that he has seen in a while.

Sometimes in my truck voltage reads 14.2 and other times it 13.8. Stock 130 amp alt and a xs d2400 under hood. And big 3

While moving I had to remove my subs and amp from my car. When hooking them back up in haste I hooked up my power cable to the ground and my ground cable to power. Sparks flew and wires were disconnected soon after. The inline 80 amp fuse burned out. Fuses on the amp were fine. After replacing the inline fuse and connecting the amp correctly the amp will not turn on. I checked the fuse in my Alpine 9887 and it was still fine, I replaced it just to make sure. I opened up the amp and everything looks perfect except a few brown solder points located on the steel plate near the ground/power connections. Are these brown spots just left over flux or do these points need to be…

This May sound simple to some but wanted some clarification. I am installing two batteries in my trunk. How they will have to be installed will require me to put about a five foot piece of wire between the positive connections. I will be fusing before first battery where it entered trunk location and fusing after second battery before amp connection. My question is should I install fusing after the first battery and then install a second fuse before it connects to the second battery or will one fuse between them be sufficient?

I currently have a 1000 watt Rockford fosgate. I want a bit more output from my xcon. will upgrading to a 1500 watt amp make a difference? I am planning on buying a sundown from db-r. any input what so ever is appreciated.

im using a crappy boss flip out head unit. and my system getting to loud to where it is shutting my head unit off until i hit the power button on. any suggestions on what is the best head unit to get?

Here's the thing, i was considering getting 2 - 12" older model p3s, 2ohm subwoofers, Power Handling (Watts RMS): 400 Watts RMS 800 Watts Max With this amp http://www.rockfordfosgate.com/products/details/p1000x2 Rated Power (RMS Continuous Power): 300 Watts x 2 @ 4-Ohm 500 Watts x 2 @ 2-Ohm wired with the 2ohm version If i can't find the older ones in 2ohm, i've come across the 4ohms, but wiring them would only deliver 300 watts, is this enough or do i have to get the 10"(which only require 300)? going in the trunk of a car, have 39" width and want to do less than 8" deep, ~16-18 high(considering leaving a spot on th…

The only dash kits for my car are ugly as hell and are known for malfunctioning. I would like to use a tablet as a "head unit". Is there any way I could use a 3.5mm audio jack to a split RCA to get a signal to a sub amplifier and a 2 channel amplifier? My stock system sucks and doesn't feature usb and I don't feel like tapping into my speakers with a line output converter.

what are some high efficient amp brands? 3k-4k watts I know mmats and b2 audio make some efficient amps.

What voltage is bad on amps.

Do you like the new 45 degree angled connectors or the straight out connectors?

So i have an Fi Car Audio SSD 12 inch Subwoofer and a planet audio amp and the box is a groundshaker sqpxl 1 12 at 33 -35hz and how do you guys think i should tune my amp to this setup

In probably a month or so I will be purchasing 2 sundown SA 12s, and I'm trying to figure out which amp would be best for the subs any suggestions would be appreciated. -Hifonics brx 1600.1D -Hifonics Zrx 1800.1D -Audiopipe AP 1500

How much battery would you guys recommend for park n play? I'll have about 2k to the lows, and would like to be able to go to a car show in my hometown and show all the highschoolers how it's done. I'm drooling over this, i've been waiting to do a build of my own for so long, and daydreaming conveniently leaves out all the requirements that need to be satisfied before the fun part. I'd like to be able to play the subs with the car off, not for ridiculously long, an hour would be the longest I could see happening; I was thinking instead of two marines from walmart, i'd do a D3100 or a D7500. I'm pretty sure the 7500 is bigger than i'll -ever- need but I mean, it's kind…

i do not know if this is the right section for this, i was wondering if you would see any voltage increase in creating a heatshield or putting sound deadening around it to keep it a few degrees cooler

Anyone know if this is really a mono amp as some say? Specs say it's a 2 channel 50 x 2 @ 4 ohms, 80 x 1 @ 4 ohms, and 100 into 8 ohms. I've read that the amp was mislabeled at the factory and is in fact a mono amp. Figured this would be the best place to ask with all the old school fanatics on this forum. Thanks.

I need an amplifier to power my D1 12" Xcon. It was running off of my Rf T-1000bd at around ~750 watts and it sounded absolutely eargasmic... and then I shorted my amplifier. So now I have two choices: Fix the T1000 for $175 and stay at ~750 watt or buy something along the lines of this http://www.dealercostcaraudio.com/hifonicsbrz17001d.aspx It may seem obvious to go with the Hifonics because of the obvious difference in power, but it seems like Hifonics isn't the most recommended brand. 1200w @ 2 ohm for $190 just seems to good to be true. What would you recommend I do? If you have any other amplifier suggestions then feel free to throw them out there. I rea…

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 …

It seems as though a nightmare has occured because yesterday my voltage was very low and my battery light kept flickering on and off. I went to O'Riellys and they told me my battery was bad. I have owned the Kinetik HC1800 for only about 6 months now and I have a custom 240 amp alternator (12v). I need advice please! If in fact the battery is bad what to I change to? Here are the specs: 2001 Ford Windstar LX Pioneer Head Unit 0 gauge & big three 2 alpine type rs hifonics brz1200d @1ohm Kinetik HC1800 (claimed to be bad after 6 months?) The gentleman at O'Reillys told me to switch to an Optima? As a car audio guy I though Optimas weren't the way to go? I was thinki…
