I went to Advanced Auto, their load test doesnt do ampers, 1st with car off all electric off: advanced auto print out battery test 12.82V measured 1256 CCA rated 758 CCA Temp 21deg F While stating: starter voltage 11.74V 0.0A time 625mS dipped to 10V running: Charging system test no load 14.62V ---A loaded 15.58V ---A ripple 37mV Went to O'Reilley's Load test 74A

Ok so I want to install my new sundown amp tomorrow but Im not exactly sure what to do with all these knobs and stuff because my old amps basically just had gain and my JL amp the dealer tuned for me.. I wanna get this right and you guys know all. I have 1 18" FI SSD in a 7.3 cubic ft ported box at 33hz with dual 2 that I'm wiring to 1ohm to a Sundown sax 1200d. I just wanna know what is suggested or you guys suggest for alll the settings.. i dont know exactly how do set them ... Like the LPF SSF and gain and umm.. crap i know there is more. Please help ME LOL. I know gain i am using a 50hz test tone with sub unhooked and a multimeter, but I don't know how to figure o…

Ok, so the tittle may be a little confusing. Sorry about that. But what I am trying to get a answer for is to know whether or not, 1 watt, equals 1 watt? For example, lets say one company claims 1000 watts rms @ 1 ohm. And some other company claims the exact same thing. Now if we set these two amps up to a controlled vehicle/setup, why would one seem louder, or just plain oh better than the other? Obviously the main possiblity would be because someone is not providing that 1000 watts, but lets say we testing both amps the exact same way, with sophisticated equipment and techniques, to find out that they are putting out exactly 1000 watts. Then what could be the reason? T…

ok i have a problem with my voltage. i can't seem to find the problem so i was wonding if anyone could help. I have a 250 amp alt with 2 runs of 0 gauge 3 batteries one is 100ah and the other is 139ah. Plus the blue top under the hood. The amps are a sundown 2500 on 4 12 skars and a sundown 1000 on 2 skar 8s and a old school Rockford 1500 on the highs. But at full tilt I drop to 11.8v and driving 12.2v idk what the problem could be. all grounds are to the frame and i did the big 3 all 0 gauge. all batteries tested fine. If u have any suggestions please let me know. Thanks!

I mean exact wiring for this...i feel like it wasnt done correctly bc we are incorporating the crossovers into the mix. STOCK HU. Rockford Fosgate 3sixty.2 Crescendo 800.4 Crescendo 1500.1 2 sets of Mezzos. 4 tweeters and 4 6.5's Fi Q D2 Im not sure why, but my guys that helped me out with they system incorporated the crossovers into the system. I thought the 360 could be used instead of crossovers. If someone has some time and would really like to help a fellow car audio fanatic out, how would you wire this setup? I would love to see a diagram drawn out!

So like the title says, im looking to buy bout 50ft. of 1/0 power wire. Which brand should i go with? Have been looking at stinger hpm, knu kol fleks, kicker, welding cable but not sure what size and if its even good for car audio, and shok. Going to be running approx 3.5k watts of power from it.

hi, i have this amp : KOIILER XM-6666 2CH 420W and i want to add to my 2001 bmw x5 , i have one each door 2 speakers -1 bigger size regular oem speaker) and 1 a smaller size (twitter oem) and also on the top dash i have 2 twtters oem's and i see in trunk that i have all wires coming there, i also have a box with 2 speakers (it looks that is the sub-woofer) so now how should i connect all this to my above amp with out burning those twitters ? the head unit in front that i am using is the new dynavin e39a (d95) from dynavin[dot]com let me know ,any advice! thanks

Would 2000 be to much for 2 SA-10's? I was told by Jacob too put them into a 2 cube box, but i dont know if thats too much power.

Ok, I'm making myself look stupid asking this, because I pretty much know the answer, (no). But, what if I do multiple runs of 12 gauge wire from the battery to the amplifier? The 12 gauge wire I have is from Sears, I have 500 feet of it, it says it handles 600V if that matters at all. Anyways, my real question is, how many runs of 12 gauge wire should I use to power the amplifier? It's gonna be running at 4 ohms, possibly 1 ohm later, it's rated to do 750 RMS at 4 ohms, 1500 RMS at 2 ohms, and it's 'unstable' at 1 ohm, but these are the same amplifiers Steve Meade used before he got his new ones, and he ran them at 1 ohm just fine after removing a certain diode, which I …

I was going through some boxes of my old belongings and stumbled upon my old school Autotek stash. A 7050 BTS, 7100 BTS and a 7003X electronic crossover. I do not have any other information on these gems (I do know they were made by Zed Audio), and there is very little on the internet about these. I contacted MaxxSonics and was emailed a owner's manual, however it was missing a few pages. I'd appreciate any information anyone has to share about these. Other then having to purchase some new Molex connectors for the speaker wires, I'm looking to put these back in service. Now if I could only find a box with a stash of 9050's or 9100's....

So I am looking for some help choosing an amp, but I need help because with my speakers I have the options of making ohm loads at either 0.86, 1.26, 1.5 or 3.43. I am looking to push a minimum of 900 and a maximum of 1200 watts continuous. My absolute price limit would be 250, but the lower the better, I'm actually looking for the cheapest that I can get away with while still meeting my requirements.

so i sent my money to dominick irraggi for a custom hand made alternator, and havent heard back from him since. havent gotten an email, and he will not answer my calls. i have left a message, but when i tried to leave another one i got a message saying his voice mail was full. USPS confirmed that he recieved the money order on the 11th, and that was a full week ago that i have waited and not heard anything from him. can anyone help me out here, i dont wanna start pointing any fingers, but a full week when i havent heard from him and dont have an alternator yet he is holding $500 of mine isnt exactly letting me sleep easy at night. anyone else on this forum dealt with him…

KnuKonceptz has a 1/0 CCA amp kit for 60$. Their 4 gauge OFC kit is 52$. I know pure copper is better than clad, but is 1/0 clad better than 4 gauge pure copper?

So my knew 220 anp alternator came in I cant fully test it cause Auto Zones tester only goes up to 100 amps but it's working fine as far as I can tell. Here's my problem my 2002 Taurus Idle stop is set around 900 RPM (no dimming out of gear) holding at the 100 mark on Auto Zones meter but when I put my car in gear the RPM drop tp 550 to 600 only giving me an output of 68 amps so if I'm at a stop light I get slight dimming. I did a eye test and left my interior lights on and the get super bright when I get to about 1400 to 1600 (not exactly sure cause the guage isn't that defined) with absolutly no dimming. Has any one else had this gear engaged problem and can it be solv…

my alternator has 110 amps and i have a sundown saz2000d and getting the xcon...yah.. gonna get a beefier bat in the front and a decent size in the rear. how many amps u guys putting out on your alternator and how many watts u pushin out of your amplifier?

I have 2 Massive Audio D3000.1's right now with the gain turned up about half way. I put a recommended 100amp fuse in the holder... today i got in the car, turned on the stereo and one amp didn't turn on. I checked all the wiring, everything is fine...checked the fuse, fuse was fine. The amp doesnt turn on at all, doesnt go into protect, nothing. I used a multi meter to check the voltage, the remote wire was reading 12v but the power wire is reading 0.03v what happened?? :S

So I was just about to buy the AudioControl lc2i and I saw that it has "2 speaker-level inputs with 400 watts RMS power handling". I have 2 crescendo bc2000s and going to have 1 crescendo c1100.4. I won't be using them all at full output, but somewhere around 3.2k rms all together. Does that mean it can be hooked up to speakers that are getting up to 400 rms or does it mean that it can only support amps up to 400 rms. I looked at reviews to see if others have used with more power and they were all under 600 rms. I didn't see any other LOCs that support more power. Will the lc2i work? If it is that I can't use this one, are there any other LOCs I can? Thanks. http://www.cr…

can anyone recommend me a decent budget amp for an xcon? I've been getting a lot of tickets I don't have money for a sundown right now.. any feedback is appreciated.

i work at a shop and have a customer who wanted to buy a large power amp. none of our main dealers have anything in his wattage range. so.. down for sound has a JP53 that calls for 600 amps of fusing... then we have a tara amp thats calling for 209 (music) 419 amps sine. both claiming 5KW of power. 120 - 390 amps of difference is (any way you slice it) a massive change in electrical system demand. why would anyone buy a ...? is tara incorrect? bottom line - im digging into efficiency numbers that ive never really had to care much about when working with 500-1500w JL and rockford amps...

Is it possible that the 900 d can out do the memphis amp? Thinking about going all powerbass. Switched from my f-150 to a xterra. 3db jump to a 144.5. Hoping to get better going with all powerbass. Thanks

Just for background information: I use to have two 12 inch Cerwin Vega's (bought in '03, no idea was model) rated for 400w rms. They are 4 ohms, single voice coil. I have them in a sealed enclosure. It was not made to spec, but it was the closest premade box I could find to spec. I think each woofer wanted something like 2.1 ft^3 or something. Lastly, I bought a cheap amp..Boss Ripper 995. Below are the specs on the amp: 2- Channel MOSFET Power Amplifier Power Max (2 Ohm) 500w x 4 Power RMS (4 Ohm) 260w x 4 Power Bridged: 1000w x 2 Tri-Mode VU meters [power level] Cooling fans Remote subwoofer level control Line and speaker level inputs MOSFET power supply Line out…

ok so i have the audiobahn flame q 12's (yes i know not the greatest but thats what i have to work with till later) ok so i know these say 1100rms but im pretty sure thats over rated but anyways i have them in a ported box right now with about 400 rms i think going to each one but i know they can do more cause they are barely moving....so does anyone know how much they can really handle or whats a good mono block that will push them good just not to the limit????

as the title says I need a downloadable users manual for the cda-7949. Alpine doesn't have them or pac parts. I'd be glad to pay for copied one of you have it. All help appreciated. Thanks, Joe. P

I've been looking for a cheap amp to power 2 morel tempo 6in coax, and i found a small one, but i came across this CRAZY deal and for the same price, i get more power, plus extra to give my sub in the back more than it gets right now http://www.ugotadeal.com/product_info.php?...uejmadbkkre83j5 and if thats not enough i can always go with http://www.ugotadeal.com/product_info.php?...uejmadbkkre83j5 for a couple bucks more no prob. I just wanna make sure it's worth it because I've never heard of Crunch before yesterday

got a couple of memphis 16-st1000 amps and i was wondering if they can handle a .5 ohm load for burps?? anyone have any knowledge? all info is greatly appreciated. thanks
