Hey hi i have the MTX 2300x amp , i am about to put it in my car for a sub, but i can;t remember which two speaker outputs to use the markings are all worn off could you let me know thanks for any help

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???

Anyone know anything about these old series 1 amps? Rockford Fosgate 4 channel amp, Series 1 4060x with high and low crossovers - $50 shipped (4x30wrms@4ohms, 4x60wrms@2ohms, 2x180wrms@4ohms) I'm not sure that such an old amp has the best crossovers for SQ purposes but just wanted to see if anyone had any experience with em and whether pricewize was even worth it.

Im mainly looking at the Alpine 7998 and 7995. Both units are deadhead units. Are they made with higher quality parts since there is no internal amplifier? Do they have better sound? I know the 7998 is going to have the advantage because it has better time alignment and better eq options. But just wanting the opinion of guys that have experience with older alpine units. Im also looking at the 7897, its not a deadhead deck put I hear its also extremely nice. Any opinions?

Hey guys, I have an old school RF amp. I believe it's a 25.2 Punch (All Grey with the side mounted fins). It has the card on the back of the amp to switch between full/ low and high pass. Does anyone recall the crossover points to this model?

So i have an old school kicker ZR1000 2 channel "cheater amp". My buddy gave it to me to use and see if i could fix it. the only stipulation is i can never sell it, if i i get rid of it, it must go to another audio guy who would value it. Anyways, i hooked it up about a week ago and have no output. it has power, no protect light and the RCAs are good. i can turn the gain every which way i want but get no ouput. Multi meter reads 0 across the board on the outputs. i opened it up and see no visible damage. He last used it in 2007 and has had it stored in his house since. I'm just wondering if it would be worth getting it looked at and repaired, and if so, what would be too …

Presently I own two Coustic 505DR's, three Coustic 510DR's and one Soundstream Rubicon 702. All pretty sweet old school amplifiers (if I do say so myself ). However, I'm very seriously contemplating selling them all and picking up three or four Rockford Fosgate T3002's. I'm wanting to compete in IASCA 0-600w class. With the RF's, I would have potential power of well over 2kw, yet still remain in the 0-600w bracket. With my current amps, I would be pushing the limit of 600w with even two of them, and I wouldn't have much more actual total power output than that 600w. Plus the RF amps are 1ohm/channel stable, were as the Coustics are not.....so the RF's really have fut…

Whats the lowest load that anyone has ran a ols school transanna amp at I ran the 200x2 at 2ohm before with no problem i was wondering if anyone has ran one lower than that successfully before.

OG guys - Price & spec cheeck: Rockford Fosgate HU Model # RFX93206 For a local guy looking to sell for ~$200 PLZ & THX -Nick

I have an older(99-01timefame) lil wonder 4 that I have misplaced the crossover/filter sip chips for. Does anyone know if they are an electronics supply house item or will I need to contact Soundstream to replace them?

I have two U.S. Amps that I have had for years and I am wanting to get the specs on them. I had them installed in another vehicle that I recently sold and I am reinstalling them in another vehicle. Before I sold my other car the 150 fried which sucks, but another reason I am wanting the specs is to find out if it would be worth fixing. The first amp is a US 150 the other is a US 25.

i got my hands on one.. it should be here in the morning.. i got it from a friend.. his dad has it in one of his old broken down trucks, (rednecks with lots of money) anyhow, his dads, brother did SPL back in the 90's and this is one of the amps he used... he knows im into spl so he asked what i would give for it... i know its a surf borad cheater amp fom years past, i knew them to be a pinkish purple but he says this one is silver, and about 4 feet long, he said the number on it is HC100 .... anyway. its in working cond, what kinda resale am i looking at on this?

I have a Hifonics XX-Colossus II, would the new Hifonics Colossus be better or worse? Mine: http://www.sonicelectronix.com/item_5382_Hifonics-XX-Colossus-II.html The new one: http://www.sonicelectronix.com/item_32990_Hifonics-Colossus.html I noticed the new one's CEA-2006 compliant.

a spanish newspaper with chicks wrestling. haha not really but keep reading. First wanna say a BIG thanks to Danssoslow for just sending this to me for nothing. Thanks. now onto pics. its a vulcan VI by hifonics. pretty old school amp. now from what i understand its a 2 channel amp. so im assuming that the red/black are power and ground and the one set of wires are marked - and + so im assumeing the orange is remote and the other set is the other channel? if so which is positive and which is negative? anyway thanks to danssoslow im sure ill put it to use. ohh haven't had a chance to hook it up but will tommorrow for sure. thanks Dustin.

I am waiting for my new amp to get here and hifonics brutus 2000 watt should be here teusday or so

I am currently on my third high output alternator in this car. Both my yellow top under the hood and xp3000 in the trunk have been tested for bad cells etc. they are each fine. There is no indication of belt slip occurring whatsoever not even silent. Big three upgrade is in place. The alt charges perfectly fine for a week or so then just stops putting out amperage as if its a regulator gone bad or rectifier bridge that's somehow over worked itself. Besides mounting it there is a run of positive to the battery from the charging stud and a one-wire charge lead that I splice into a 12v connection for the regulator to operate off of so I don't understand where the issue is co…

So I recently traded a Kicker 350.4 for two Tang Band W6-1721 drivers and now I have a question. I have never thought of this before and don't remember seeing it done, but on a four channel 2 ohm stable amp could you run two channels at 4 ohms and the other two at 2 ohms? I want to have the Tang Bands up front with my Tantric 6.5 components and in the rear doors have a second set of Tantrics.

I'm going to be running two amps here soon, one per sub. My question: Instead of having to run one bass knob to each amp/sub, could I somehow use just one for both? They are the Audiopipe APSM1500 amps. The knobs have the 3.5mm cable from the knob to the amp. They are like a headphone jack from what I can tell. Could I just use a headphone splitter from one knob and run the two separate wires from the splitter to the two amps?

I have a cheap 2 channel Lightning Audio amp that was given to me. I first hooked it up on my bench to see if it worked. It did, however, it sounded like it was only playing sound that was panned hard left/right and nothing below about 500hz. I took it apart, and the ground that was soldered to the board from the RCA's was broken. If you pushed the RCA's so that the connection was made, it played fine, but one channel was about half as loud as the other. So I took a set of RCA inputs from another amp that didn't work and replaced the ones on the LA amp. The exact same situation.. One channel is twice as loud as the other. I've tried 3 different sets of RCA cables and 3 di…

Is the wire from the alternator supposed to be connected to the positive or negative battery terminal?

Is there any online retailers that will ship to Canada? I've contacted Battery Direct in Edmonton, they suggested a blue or yellow top, but there prices seemed kinda expensive..

I'm helping a friend put together his system. This has to be such a rookie question but its something I've never had to deal with, all my systems I buy decks with enough RCA outputs. He refuses to spend money on a deck. He has a few laying around but only have 1 set of outputs on each deck. He plans to use 2 amps in his system (highs amp and sub amp) what's the best method to do this as far as running the rca's.

Can I safely wire my 2 door speakers at 4 ohms to a 4 channel amp. I have heard it's not a good idea

My friend and I are installing this head unit: Dual XDVD8183 All In-Dash Car Stereo Receivers Car Stereo Receivers and Head Units Car Audio Car Audio, Video, & GPS Navigation - Sonic Electronix and there is only one output for the subwoofer amp. So instead of a red and white one there is only a blue one for the subwoofer out. There are two normal ones for the front and rear, so could we just use the rear outputs? Also there is a single center output, could you use this along with the single subwoofer out? I can take pictures if needed.

I am looking at a arc xxk4050 amp that is a couple months old he wants 300. for it. Is that a good price? the sheet says 118-120 watts a channel. I have heard a lot of good things about arcs but never heard more than a couple minutes in a demo room
