I am going to Gain match the Amps using a Dmm & an O-scope, anyone done this ? have any input on how to get the most outta the amps without Overdriving them ??? just want to do it different than Strapped any constructive suggestions or input is welcome

I'll be running a SAZ 2500D and a SAX 100.4. The 2500 will be at 1 ohm and the 100.4 will be at 2 ohms. So that's roughly 3140 watts. I have about a 50 ah battery up front, will have a 100 ah battery in the back (deka intimidator 9A31), and I will have the big three. Will I need a high output alternator? I'm not sure what my alternator is rated for. I'm guessing its between 60-100 amps. I have a Chevy 1500 1990 4.3L V6 w/AC.

a friend sold his rf power 800.2 to another friend. this is the same 800.2 that we used to run a pair of 15" id spl's at 4 ohm stereo (the subs were dual 2) and it beat the hell outa them... now the new owner says the amp is smoked..literally...yet when i pulled the case, there was no smoke/fire damage..hell, not even a hint of overheating really. the new owner is running 2 subs, one a he2 that is dual 4, one a boston that is a single 4. he runs everything parallel and bridged...this totals a 1.3 ohm load, correct? i say that the amp is just going into protect...i mean it is just 4 ohm stable bridged, correct? he says i'm full of shit and that the amp is messed up. we hav…

i have a 10" RL-i D4 on the way, now i'm trying to choose and amp. goals were... 1: no more than $250 with shipping tacked on. would like to make it less if i could, but if the choice means paying that much than so be it. 2: a minimum of 500rms at 2ohm. sub will be in a optimum recommend size sealed box which i believe was .65 cu.ft. i have done lot of searching and reading reviews and posts with people giving their opinions, not only here, but other places. i have it down to these choices. Cadence TXA-1000D Hifonics TXi 7506 Phoenix Gold R8.0:1 Phoenix Gold Ryval V8001 Infinity REF611A Alpine MRP-M650 again, cheaper would be better, but from what i remember of Phoenix …

Here's my head unit specs: 5v peak/ 2v RMS RCA output on all channels 100 ohm low impedance pre-amp outputs bass frequency adjustment - 60, 80, 100, 130, 150 and 200hz bass q factor - 1, 1.25, 1.5, and 2 treble frequency adjustment - 10, 12.5, 15, and 17khz sub x-over - 80, 120, and 160hz sub phase - 0 - 180 sub level - variable looking at the Audiocontrol Matrix, running two US Amps.

I think while my truck is in rebuild mode I will go ahead and upgrade or change to a newer unit. I love the alpine but want to look at something different. Looking at the deh-80prs or the avh-P8400bh. Sq wise the 80 looks like the choice but im sure I would be happy with either. Any other good dd units out there? This is what I have now and will be letting go cheap to anyone interested http://www.crutchfield.com/S-lCerWQCN13n/p_500IVAW200/Alpine-IVA-W200.html#details-tab I want good control of eq and options for hpf and lpf. Any other opinions? I have a alpine 600 watt 4 channel that will cover the mids and highs unless I pick up an additional small 2 channel just for t…

I let it sit for a bit and I guess from what I read online that if it gets a little dust on or in it. The cd player doesn't eject cds. There is a disk in there that plays fine. It can't eject it though. How would I fix this?

Hey guys my brother drives a 1996 Jetta GLS. The other day his car quit playing music. I know its not the head unit because I took it out and tested it and it works I even put in his older pioneer that also works and it played for about 1 second then it stopped playing music (same happened with the first head unit also). My question is what could be the problem cuz I have no clue. Any help would be appreciated

Right now I'm looking for an amp to run a single 12" under rear seat of truck. Sub is a rockford fosgate p3, Thought I would poke around on here before asking questions ...

Am running 2 FI 15 inch Q's with BP power on an AQ 2000 watt amp in a 2000 dodge dakota. I upgraded to a high output alternator (230 max output, i had it tested), and i have already completed the big 3 with 1/0 gauge wire. I am presently using a 850 CCA battery in the hood and have no space for a battery inside the truck. I am currently experiencing diming and since am not interested in using a Cap, i was woundering if i took out that battery and replace it with a kinetik 2000 or 2400 watts battery, would that solve the problem? Thanks

Alright I just want to clear this up so I don't fry an amp. Here is how I will have my set up wired. What do I disconnect just the front battery negative? Or what? And do I take out all the fuses then plug in the postive to the amp and THEN negative ? I just want to make sure

I have a 4 groove belt on my lancer and I've been told buy a HO Alt dealer that If I chose a 200 amp unit I would experience belt slip. Does anyone here have a 200 amp alt or higher on a 4 groove belt? If so, does the belt slip on you? I was informed that 150 amp unit would work fine. My stock alt is 85 amperes. I'll be running a Sundown 2000D plus a component amp (undecided which one). Would 150 amp unit and a PowerMaster D3100 + front battery be sufficient power for me?

Which amp would work best with 2 alpine type Rs 12". Either an alpine pdx 600 watt or alpine mrp m1000? and what ohm would you run it at 2 or 4?

Can someone tell me the differences and what all goes about these processes

Okay, let me start off by saying I've installed a countless number of CD players in cars. This is the first one I've had trouble with, and also my first Pioneer. I bought an 880 off of ebay a while back for about $200. I initially installed it in Octoberish. It would work fine when I normally had the car running, but when I switched my lights on it would cut in and out every second. I attributed this to a couple of wires being switched. (The first wiring diagram I had was wrong.) Well I eventually got this fixed by switching the two wrong wires. My CD player would now work with lights on and off. However, when I would switch from on to off my CD player would cut o…

So hoping others with more knowledge then I, could help clear up the wondering of my mind... What are the benifits of a person running a daily, (non-competitive) sub stage at 4 ohm compared to 1 ohm? Just curious if the pros were great enough, to dish out double the money for an amplifier? Thanks for everyones time and input!

I know almost everyone here has auxiliary batteries to push their systems, but how did you wire them up? Did you run an output wire from your alternator to the primary battery, then run another run to your auxiliary(s), or did you run wiring straight from the alternator to both? Anybody using a dual-battery isolator or relay system, or is it just a waste of time and/or expense? GM originally used a parallel wiring scheme for its factory dual-battery system, I'm just wondering if that is the BEST way. I don't want to have any adverse effects on the alternator. I just want to do it right.

I'm looking at two amps a sundown 2500 or the crescendo 2000. I have the power to run either amp. I will be running it on a pair of disadvantages 12's.2 ohm daily, .05 ohm at competitions. What would u guys choose?

Gonna power a BTL N2. Opinions? Powered by a 200 amp alt and just 1 battery.

I am somewhat new at this and feel I need to run more batteries, this was also recommended by a stereo shop near where I live however they would charge an arm and a leg to do the job. I was wondering on how to do this, I was thinking parallel, but I was wondering how both batteries keep charged....... Thank you Jonathan Thompson

Hello I am an amateur stereo guy in need of advise on setting my amp. I have the gain set to 21 volts on the front and rear of 4 channel with a 1khz test tone I have the gain set to 41 volts on the 1500d amp with a 50hz test tone Those settings were given to me by a friend My question is where to set the crossovers? the low pass/high pass filters the subsonic knob and the 2 push in buttons I currently have the front channel run on the crossover on the head unit set to 100khz with a 24 slope Rear channel is off on deck, and set on low pass on amp but not sure what the settings should be on the amp, the deck does not give me a low pass option on rear channel The sub is cur…

well i bought an alternator a week ago and it just arrive today. now i have a question how can i really check for the output the guy i bough it for said it was a 300 amp alt from excessive amp but i want to make sure it sure is (not that i want to say the guy is a scammer) but for my personal intentions of using it. any help would do great, i know i shouldnt take it to autozone or any place like that results wont come right

My pioneer HU died the other day when I hit a pot hole and now I need to replace it with somthing better. I've been looking at the Nakamichi CD-300,400,and 500 and also the pioneer premier 800 and 880. I know the nak's don't have nearly the features of the pioneer, but I'd kinda like to try somthing different, and I like the simplicity. Do any of you have opinions or suggestions? I'd like to get the best sound quality out of my system without spending much. I've got CDT coaxials (which are awesome for what they are), and a pair of 15" kicker L5's pushed by a kenwood 600w cheap amp. I got the subs mostly because I was young and they look cool and got a good deal, just…

Hey everyone, I was just wondering about the capability of a USB splitter operating off of a head unit. I'm specifically talking about an Alpine CDA-9886 but this would apply to any HU that has a rear USB port. The reason I'm asking this is because if I ever wanted to use a flash drive rather than an Ipod. It's not practical to use a flash drive for those kinds of decks. I'd be getting a 1 male input/4 female output cable, but I have to know if it would work first. Thanks again for the help!

I need to choose an amp for a pair of Maw-15's I was thinking the Sundown-1000D. Seems like it would work good being when I wire both subs into it. The Rms wattage would split and it would be powering the MAw-15's to their full RMS which I know isnt everything but ya know. Any Input. Thanks in Advance for all the help.
