Amplifiers / Head Units / Processors / Electrical

So acouple weeks ago I had a viper r350 installed in my truck and I took the liberty of ordering two Directed 515r backup battery sirens... I tested them now with the included keys and they're pretty loud. My ears were pulsating. Well I'm reading the instructions on them now and could use some help...There are 4 wires on the unit itself: red - +12v, fused at 5amps, constant source black - ground violet - "(+) Siren Input: Connect this wire to the (+) siren output of the security system. If using a DEI security system, this would be the brown (+) siren output wire." green - "(-) Siren Input: If using a security system with a (-) siren output, connect this wire to the sys…

I was about to place an order for my big 3 wiring and the ought gauge wiring for my my 1200D. Really dont want to order a surplus here. Trying to keep the price low as possible. The amp combo kit that im getting comes with 17 feet of ought gauge. I am sure that it wont take 17 feet to reach the amp so I may have some left over cable. Not sure how many feet it usually takes to do a big 3 in a engine. Any thoughts would be nice. I am considering buying 10 extra feet. If you think I can do it with less that would be great. also thinking of getting x2 of these battery terminals LINK to terminals. I am assuming the big 3 will take 1 cable for the alternator, the amp will take …

Anyone know of any amps that are under 9 3/4" width, needs to be rated atleast 1200watt at 2 or 1ohms on 1 channel. Found a couple hifonics but there 9 3/4 and 9 1/2. Any suggestions?

whats the optimal fuse size for a run of 0 guage to run a bc3500?

Looking to go active in my truck and have found one of these pretty cheap. Very budget oriented system, but would prefer to keep everything active. Does anyone have any thoughts on this beast? http://www.pioneer.be/be/product_detail.js...xonomy_id=25-38 It looks like it will work for what I would use it with: rli10" and a mid-range/tweet combo tbd

I need a little help on this one i was going to buy the Knu Kolossus Fleks 0 Gauge wire for my Crescendo 3kwp but they just came out with a mix breed wire the Kca and it is half the price witch to me is great cause im in hight school working part time dish washing lol but would there be a audible difference ? thank you.

I had blown one of my subs a few months ago so I unhooked everything and removed from vehicle. After doing some upgrades and getting new subs in, I finally reinstalled them yesterday. The problem I've ran into is that the amps aren't producing any sound. They power up and show that there on, but no sound. What voltage should the remote wire show? This is the only thing I can think of to check. I will say though that when I had a sub blow it blew the fuse between batteries and the amps where underpowered for awhile. Could this have caused internal problems? All help needed fast!!!

Looking for budget amplifier to power a 12" SSA DCON subwoofer SVC or DVC 4-ohm (1.2 cu ft sealed to spec). I would like a class d amplifier rated at about ~300w rms clean (give or take, this is a low power budget system). Any ideas?

I have an xs d3400 and plan on getting another, my problem lies that my altenator has a run of 1/0 to the vehicle fuse/power distribution then charges the batter only after passing through a 140 amp fuse that bridges the battery connection to the altenator charging wire. I plan on running a SS Da Vinci for a 2 way 6.5 system up front and some 5 inch rear fill, and an old school SS tarantula. I will be using BLT4's, will the 140 amp fuse be enough to charge the batteries without blowing, also thinking about taking advantage of a MS-8 processor. please help thank you, also i will have two runs of 1/0 from batt to batt and batt to amp.

Hey guys... I have posted this on a couple other forums and have not had too much feedback. Here are the details: 2007 Chrysler 300C Fi Q15 Dual 2 (Ported) "Big 3" Upgrade I am looking for an amp (1 ohm mono) to run a Q15. I would like it to sounds as good as possible (obviously) with a budget of $350. So far, I have narrowed it down to the following: - US Amps MD-1D - Sundown SAE1000 - Audioque AQ1200D - Cadence iA7 All can be had for $350 or under... what is my best bet for a good LOUD SOUND QUALITY amp?? And why one over the other?? Thanks for all of your help!!!

ok so heres the deal just hooked up my system the other day and turns out i got nasty volt drop from 14.3 to 12 with my amp setting on a little less then half no bass boost head unit at 3/4 so heres the question what brand alternator do you run, amps on it? price you payed for it.? Ive been looking around and i have mechman alt. dc power georgia power and irragie alt im shooting for 270 amps.. would be appreciated thanks in advance

so i am going to get this out the way right now, if you don't have anything constructive to add please don't post. looking for serious feedback here. i am just curious and have an itch to know, so i am sorry if this seems like a stupid question to you guys. ok so i have a pretty decent handle on car audio, been in and around the scene for years, but most of my expertise in in other forms of electronics, now my room mate and i just got done installing a killer system in a friends cadillac, and we only have 1 possibly 2 depends on how messed up the other one is of the bass knobs we need. they are for 3 older series RF bd1000's. any way my question is what stops me from usin…

Hi fellas I have a question that will I'm sure be easy for you to answer. I have never ran bigger than 4 gauge wire, never upgraded the big 3, and never dealt with any of these following products. First the wire I will be ordering is http://www.wireandsupply.com/product_p/sgx-2-fslash-0-fslash-01.htm . The lugs I will be using are http://shop.genuinedealz.com/Marine%20Electrical%20Supply/Tinned%20Copper%20Cable%20Lugs/00%20AWG%20Tinned%20Lug/?sck=12205831 . My question is what size ends should I get, they offer from 1/4 - 5/16 for the 2/0 gauge wire. I plan to use them on the 2/0 gauge upgrading the big 3, I plan to use them on my battery terminals, and I plan to use them…

I have an old Pioneer DEH P930 that is in need of repair. I believe it needs a new ribbon cable, but no matter...my questions center around the deck's features. One of my favorite features of the unit was it's capability to make low bass from recordings where there was none. I never checked the output on an RTA, but I would be willing to bet that the effect is that of an Epicenter, where a bass line is created one octave below the lowest notes in the original recording (if I remember reading that correctly). The owner's manual mentions an "Octaver" function and "Dynamic Bass Emphasis"... does anyone know which of these two features is creating this effect? I called…

I would like to compare it against a new PPI class d 4 channel to see if all the time they spent on it produced results or just junk. I can't find squat for user reviews of the vlx4150

Hello, I am wanting to upgrade my OEM alternator before I blow it . I am looking at an Iraggi 200 amp for $399 or 220 amp for $439. I dont mind the extra $40 so I am thinking 220 amp. Mechman is also an option as many people in my area give good reviews. The only downside is they dont make one for my car. If they did I wouldnt be writing this. Currently I have a 2009 Toyota yaris 4 door sedan. 1 JL Audio 1000/1 powering 1 15" Fi BL Loaded. Also 1 600 x 4 amp for mids and highs. I have another JL 1000/1 sitting in my closet begging me for some action. I want to do the alt. upgrade first then Big 3 then a yellow top or kinetik or something. ( Im upgrading grounds imm…

Does the epicenter help increase you spl or does it just act like a bass boost where it will just cause the amp to clip. Would it be a good idea to buy one if I mainly use an ipod?

The guy has two for sale a big one and a portable one. 100 for the big one. 50 for the portable. I can't tell which one is which but is this a good deal anyways? I don't know how much I could use this or even how. But I know they're expensive. So my question is should I call him and get it now or just settle for setting my gains with a dmm or just by ear?

hey guys... I have 2 1000.4 's going to my front doors . they have been sounding great, nice and clear and no distortion. I have been having some ground problems lately and had to drill a new ground. After that they were back to sounding clear and crisp. Now about a week later all the static and distortion came back to the point were I almost cnt even hear the music. I checked the ground and the ground is good. i checked the rca'a and there fine. ( I do have a few splits on my rca's and those were fine as well). I was told by someone who works at a car place that it could be the deck because it only gives out so much amp or power roughly 2 volts or 2.5 and he was saying t…

I just got it off craigslist for a $100, its rated 150x1@4, 300x1@2 and 800x1@1. Are these underrated? I wanted to know because i plan to buy a Fi Q. thanks.

Hey guys i am wondering what battery to order for my system pretty soon. i have a 2001 gmc sierra 4.8L in it i will have two level 4 dc M2's running off of a DC 3.5k and i am wondering if i should get one of these http://store.soundsolutionsaudio.com/products/xs-power-d3400-12v-agm-battery-max-amps-3300a-4000w.html or a optima or something. The XS seems like it would be more powerful. Any opinions?

I am looking to build my first system and I am a full believer in saving money but not at the expense of diminished quality. I want to get 2 15" BL's. This is in an every day driver, I want it loud but it doesn't have to be insane. I know that install is 90% of it so I am wondering how much of a difference am I really gonna see if I have Sundowns 1500 powering them or the 3000. Saying the encloser and every other factor is the same. I am thinking that since I am not looking to compete I would be spending way too much money buying the 3000 and all the extra electrical upgrades that are needed and not have that much of a noticeable difference. So if anyone who has experienc…

So far I'm loving the new system but I've noticed with some songs (the loudest) and also at idle my voltage can drop down to 12v. It always jumps back up to 13.8+ volts after the bass hits... Should I be concerned? I still need to upgrade a ground under the hood, hoping that will help a bit.

Honest opinon would you rather have a old punch amp or a new punch amp I have 3 of the punch 200x2 and a 60x2 and a 40x2 amp that I am planning to une in what i call a old school build in my eclipse take suggestion on what subs to use plan on usin a 200x2 on each sub and the 60 and 40 on highs any suggestions???
