is this the right configuration to achieve a 1 ohm load?

hello, is it possible to blow an amp with a volt. drop from 17.9-13.sumthing?? a friend of mine has a mojo 4k and he only did three burps with it and that was his volt drop is it possible to blow it like that??

I was thinking... Deep cycles (ie. Yellow Top) are meant to discharge quite a bit over a long period of time, but starting batteries (ie. Red Top) are meant to discharge large amounts of current over a short period of time, like the starter. Now for our application, car audio, unless playing with the engine off for extended periods of time, wouldn't starting batteries be better? Music is quite dynamic, and as such, starting batteries would be better able to provide the bursts of current. Now I understand that purpose built batteries such as Kinetiks and Powermasters probably have high current in mind, but when using other batteries like Optimas, would a Red Top work bet…

I just got it in the mail today and I want to intall in my 07 Suburban. Anyone here who has this install on they're tahoe/suburban, where did you mout these unit at? Did you mout it on the firewall, or did you mout it near the fuse box? Is there an easy accessory wire available under the hood that I could use to turn the isolator on/off? Also is there anything else I have to do special with this isolator since this is a newer truck? From the directions it looks like I'll go from the alterntor to the one of the isolator's hot lead. Then from the 2nd isolator hot lead to a fuse/relay switch, which will then go to the second battery. Does that sound about right? Then there a…

Ok, say I want to use a simple toggle switch to control a relay for whatever reason. Do I grab +12 from any source (battery, ign switched, etc), run it through the switch, to the relay coil, to ground, and hook up whatever I wanted to power using the switched terminals? Thanks, ~Trevor

how do i calculate power from my amp. if i have my sub wired at 1 ohm and i play a test tone say 60hz and measure the voltage how do i calculate that into watts. i know you multiply volts by current to get watts but how do you know the current at diffrent loads. not sure if im missing something i just always see people say i measured this many volts at this load so it is putting out this many watts and i never see a current measurement. is there a standard current output per load or something. just want to learn a little more thanks

I have a 93 civic with a 70 amp alternator. Right now the alternator is producing too much voltage( up to 20 volts) I suspect that my 900 watts rms stereo system(mtx tc 4001 front chan. @ 4 ohms rear chan. @ 2 ohms, mtx mxa6001 A 2ohms) is to blame. So I decided to get a HO alternator, but the closest guy that does it is in brampton a few hours drive. After doing some homework I found out that added a second isolated battery may provide better protection. Does anybody have any advice, pros or cons and what would you do? HO aternator, Second battery or both? I have already upgraded my battery and wireing for those who will ask.

I am (hopefully) about to order an upgraded alt for my car soon. I have 2 200A solenoids in the car and I need to make sure they are wired correctly before i take a chance in the alternator burning them up. EVERY COMPANY i have talked to has told me to wire them the same way but i do not believe them as it doesn't sound right so i want your guys opinion. Here is a pic of them- The top option- this is the way the companies want me to wire them, main wire from batt coming in, running of relay one to input of relay 2 then out of it to battery bank... Wouldnt that just switch 200A into another relay to only support 200A of current??? Option 2, the bottom one is what i am …

Hey all! I was wondering your guy's opinion on the best double dinn dvd/cd player with a good customizable EQ, HPF, and LPF (would consider a single with a pop out screen). Any input would be greatly appreciated!

I was looking to do a big three this weekend and was wondering how would you do the bir 3 when the battery is in the trunk. Does it take away from the whole idea?

Just ordered up my HO Alt from www.mechman.com =). This guy was referred to me by scottiej from powermaster and he has like every alt ya need and they are darn good prices. Got a 250 amp alt btw =). I guess they aren't like regular HO Alts that just get the windings replaced... they are actually like larger alts that fit into the stock locations and don't sag at low rpms like most HO's do. Great guy and I would recommend him to anyone =) THANKS SCOTTIE!

hi, i have 200 bucks to buy an amp to use to power my re audio xxx comps that i am finally installing. and i am wondering should i get a refurb sax100.2 from db-r and go passive or a new eclipse audio xa4000 and try to do active with them and i have an alpine 9887 for the processing. so it is more like what would you do type thread.

hey everyone. im planning on buying one 12" BTL within the next 2 weeks along with a Crunch GP3000D-PRO and running it at 1ohm load. going to be putting them in my 2000 honda crv ex when i get back to the states from iraq here. i was wondering if there is going to be any need for me to upgrade my electrical system/add a battery or any other electrical things i will need to do? if yes, can you please list them for me because i simply have no idea. i do not know how much the alternator is putting out now either. i have tried researching and cannot find the stock one anywhere. any help would be appreciated thanks

Well, instead of posting all this in the build log, i'll just post it here because i have a question anyways. I have\had 2 of these amps strapped together. When i first strapped them up, after several minutes, the slave went up in smoke. It was concluded that the input stage on the amp got damaged. There was no audio coming through either amp when i first tried using these. I tried using just the master. No signal at the time until i unplugged the rcas from the HU then plugged em back in... been working ever since, odd but no probs now. Got the slave amp back in and i did not have any subs hooked up to em when i had em strapped again but the slave amp went up in smoke …

hi! i need you good opinions on this amps: KICKER 750.1- - $410.66 # Class D # Amplifier Type 1 Channel # Mono subwoofer amplifier # 375 watts RMS x 1 at 4 ohms # 750 watts x 1 at 2 ohms ALPINE-MRP-M1000 - $451.72 # Mono (single channel) V-Power BASS amplifier # Class D # RMS Power (at 14.4V THD+N, 20Hz-20kHz) # Per channel into 4 Ohms: (@ 14.4V +-1%THD+N, 20Hz - 200Hz) 600W x 1 # Per channel into 2 Ohms: (@ 14.4V +-1%THD+N, 20Hz - 200Hz) 1000W x 1 i'm from europe...the price are the cheapest i can find.. in europe.. thanks

hey everyone! Sorry for another "Vs." thread, but i would deeply appreciate any help I dont know which amp to get? the memphis prd 1000.1 or the sundown 1000D, what are some pros and cons of each amp, and what amp will suit me best with a FI Q12 with a 2007 honda accord with stock power Thanks

ok so today me and my friend were taking out his back seat of his z71 to make a new box and he accidently moved his amp when we were pulling out his old box and there was a spark from the power and ground wires touching, so we moved them apart and didnt pay any attetion, but when we put the 15 back in and hooked it up his amp wouldnt come on, buyt the radio did, so we turned the truck off and re-connected the power and ground to make sure and now neither the amp or head unit will work, anyone might have an idea to what the hell is wrong with this thing, o and the head unit and amp arent using the same power wire, but they are connected with a remote wire

So I cracked open some Knukonceptz Krystal 4channel RCA cables that I just took out of my car(replaced with my own I made ). and as I suspected, quadruple shielding my ass! None of the shields are grounded, I looked on both ends all look the same 2 wire conductor per rca. I cut that black heat wrap off on all of them. 1 side: other side: close up: they all look the same as this just different color conductor wires. here is another shot of the Knu where the pants meets actual cable insulator Looking for shielded RCAs? dont buy those...

what type of fuse should i use for the amp to battery power wire (in an inline fuse holder from knuknoceptz). if this helps...the wire is 1/0 gauge, the amp is an saz 1500d, sub is going to be a bl15.

Im getting an Fi Q 15' in my '96 ex-cab s10. Do I need a battery exclusively for my system or just a nicer 1 under the hood? Under the hood I have a cheap Duralast.

Anybody know of a place in AZ where I can get my alternator rewound? Because I cant seem to find an HO alt anywhere sooo I think I have to just get it redone.... any feedback would be GREATLY appreciated!

I thought about using the Batcap 8400 because it would save weight over conventional batteries. It weighs 70 lbs vs several hundred lbs for yellowtops. Its capable of 8400 amps @16V and up to 9600 amps@12V. Anyone have experience with these and how they compare to batteries? Any issues w/these things?

I am looking for a new cd/mp3 player that I can hook my ipod up to. I have been looking at alpine and pioneer cd players. I was looking at the Pioneer that has bluetooth and an ipod hook up. If you have any suggestions it would help a lot thanks.

Hmmm so I was just wondering... Why is everyone so dead set against a cap?
