Hey all. I'm at a loss right now. I'm preparing for a build replacing my subwoofer. I will be using around 2500 watts of bass plus 250 watts of highs. I'll have one battery, but I rarely play the system with the car off. Anyways... Nathan (from Excessive Amperage) seems like a great guy and super nice, but I'll be paying $25 more for 20A less. The Power Bastards alt is 220A and the Excessive alt is 200A. Any recommendations? Comments/experience on build quality? Both come with an overdrive pully and a one year warranty. Thanks.

so i went to spl show and wanted to see what my two sq hds200 dual 2ohm that is wired for a 2ohm load and even checked them with d.m.m and shows 2.1ohms but my mtx thunder 1501d older style no elite suppose to do 1500wrms@2ohms with 14.4volts has 2gauge welding wire and at the car audio show it only clamped 844watts. Im wondering why is this and is there something im missing here and how to fix this to get my wattage up because my spl score in my 00 s10 ext cab was only 142.3 on dash http://www.termpro.com/asp/officialevent.asp?EventID=15579&Method=1000 name is david downs i entered the hardcore truck so i could have door open driver side and then unlimited car truck…

I been trying to do some research on some 7-7.5 rms amps but not really making a ton of progress. What are some good amps that's within this power range with the exception of dc. i know b2 m1s and ns1 v2 are in the category but what are some others than im overlooking? i need two budget is $3k

While sitting here thinking about how i keep reading about capacitor or battery topic.. this popped in my head. So, i am curious... With the new XS VCM, will this not only replace MLA but also capacitor use period? For those that don't know what an XS VCM is, let me briefly describe it. It is an add-on device for stock or aftermarket alternators that has an attached module that sits in your car. This module is set to any voltage in 0.1v increments up to 19.5v if your setup supports such voltage. When the VCM is used, whatever voltage is set, this voltage will NOT fluctuate...not fluctuate...not...ever(with slight exception below) In testing, it is shown that, for example,…

Hey does anyone know anything or have an opinion about this amp

So I've been researching ground connections, always trying to learn more about a subject, since I was upgrading some things its always a good time to refresh my memory. I've basically come across several ways suggested to make a good ground, and there are a few that stand out to me. 1) Using dielectric grease to seal moisture out of the connection area, with the idea that when you crank down on the nut to secure a ground lug to the chassis it will push this grease out of the way so the metal connects properly together and helps seal out moisture. 2) White lithium grease. I've seen this mentioned several times, but I truly feel it may be an outdated recommendation. …

saz 3000d vs IA40.1 give me your thoughts on a 14.4 @.5 ohm setup

Plan on using the Hifonics, rated at 750w rms for my SSD 12" coming in soon but I was thinking about a JL 500/1 which is a class D versus A/B on the Hifonics. Is $150 a good deal for a used JL 500/1? I would think the JL offers a clean 500w and I've read the Hifonics are overrated. Which one would you guys go for? Thanks! Sunny

i want to run my orion 2500d to .5ohms. i want to know what it will take to run that low i have two red tops and 160alt. two 15 inch Arsenals. shouldn that work

Just got one but how small are they really? It's 11-3/4 inches by 6-1/2 inches? Seems kinda small... Also, anyone have photos of their own collection?

http://www.woot.com/woot_detail.aspx I ordered two. Even if I don't use one / don't like it ... I'll still make a profit selling it. Seems like a heck of a deal to me, though.

I have an 05 Outback. Looking at a bunch of options. Best option seems to be Excessive Amperage who can do a 200A for 385. Anything over 200 supposedly will slip due to horrible belt wrap, and I only have a 5 rib belt. Mechman, Singer, Ohio Gen, and DC power are more cash for less ALT than the EA. So its either EA or possibly this? Stumbled across this. http://powerbastards.com/proddetail.asp?prod=Fitzall-220 Anyone heard or used one? Seems to fit WAY more than just my car. Which worry's me as far as how "drop in" it really is.

So, i had my meter mounted on the left side of the pocket below the HU using velcro. well, that was late last year (cool weather), and now... Hot Weather = the glue/tape on the back of the Velcro melting. so, heres a few pics of my dash. there is nowhere to mount it that i can see. you can see where the trim piece around the pocket is a separate piecs. i have to take that off when i need to get to my HU. so i cant mount it there. ANY opinions wanted. thanks!

I have heard a lot about welding supply and coppercableman on e-bay, what about wire and supply or electron beam (EB-flex) wire? Also I see that 1/0 welding wire in general is rated for 350 amps at 50 feet while 2/0 is rated for 400 amps at 50 feet. I don't expect more than a 20 foot run at most from my front to back battery so what size cable would you guys recommend for a Crescendo BC3500d at one ohm with a 300 amp external fuse rating? Lastly I notice there is an ultraflex cable available from welding supply (as well as directwireusa.com) that claims to contain 4x the strand count of the standard wire yet the amperage ratings are the same?

Look at this beast...... getting a quote from morgan @ exile tommorrow might to sell all my other sub amps i own to get it but it looks super bad just thought id share....

Ummm. I redid my big three. I was making a tutorial for YouTube.I added, didn't replace the original wires. In 1/0 i did alt positive to battery positive, battery negative to chassis, battery negative to engine block, engine block to chassis i guess its more of a big four. And battery is kinetik 800. And for a couple of days it was alright. But then I noticed it was having problems turning on, it would crank an extra 2 times or so. Now it doesn't start without me getting a battery charger. Voltage says 10.7 but once I charge it goes as high as 15.8 ? And then it starts up fine. I did some research, I'm still researching... Some forums in hondas, people say its the eld (…

hey guys, just wondering if anyone knows (or heard) of soundstream making good amps. im debating buying either a soundstream pca2000d or a kicker zx1500 amp. they both push 1500rms when wired at 2 ohms. naturally i would just go for the kicker because no one seems to have anything bad to say about them and are under rated, i just dont like the fact that the kicker can't wire down to one ohm if i decide i want more power. please lemme know if you heard anything bad or good about soundstream...thx-phil

what would you guys pay for a good working Kicker KX 800.2 thanx

i have a nightshade v1 15 and a rd1750.1 amp right now i have my nightshade wired at two ohms but i got the rd because i was told it was .5 stable i have 0 guage throughout big three and 200 amp ho alt will that be good enough electric to safely run this amp at .5

i have two 10" pioneer TS-W251R subwoofers in a vented box in my car and right now this kid i know gave me a prehistoric amp for me to use while i look for a new one. (im not even going to say what the old one is... its a joke and doesnt nearly cut it, ill leave it at that) so right now im in the market for a good durable amp that is not going to cost me an arm and a leg cause lets face it, im on a tight budget. so what i do know is the standard stats for my subs they have a norm of 120w and a 600w peak output and they are 4 ohms. what should i be looking at? would something like the Kicker 11DX250.1 be an appropriate option? or should i be looking at a two channel amp in…

Please someone correct me if i am wrong, i am going to strap my Sundown Audio 3500Ds and this will be my first time strapping amps, so i need to see if i am thinking correctly. The Master amp gets the input from the head-unit and a mono RCA from "BR Out" connected. The Slave amp ONLY gets "BR In" connected from the Master amp, leave the Gain and other Filters on the Slave amp set to 0. Each amp gets its own remote wire coming from the head-unit. Each amp gets its own Power and Ground. Connect NEG terminals of both amps together using 8AWG wires Wire my subs like so; Then take the POS wire from my sub and put it in the Master amps (far left) positive terminal, then take t…

hey everyone. i came accross this amp in my friends basement and he let me keep it. its an Alphasonik MA-2055. doesnt have the regular speaker terminals. has all the different colored wires. has power and ground leads coming out of the amp. on amp it says: minimum continuous average power: -55w per channel (2chan). both drive into 4 ohms...? -110w mono mode into 4 or 8 ohms. -freq resp 20-20khz -THD <0.05% does anyone have ANY info on it? couldnt find anything on google... thanks! PICS!

US amps BASS MEKANIK VLS-1 ,... has anybody ever used one or know if this is worth getting?

How do I know what to set my SSF to? The Fs of my sub is 36.4Hz Box is 2 cubes tuned to 38Hz FS of my truck is 37Hz I can give you any T/S params you need, or you can get them from here: http://www.mtx.com/caraudio/products/subwo...ta_T9512-44.pdf (PDF file, 693KB) A direct answer of what to set it to is fine, but I would like to know how to calculate it, or at least a "rule of thumb" to go by when setting the cutoff frequency.

just was wondering if i should by this capacitor i was looking at. So would a cap benefit me in a burping scenario? my car will be running 2 sundown 4500's and a sundown 100.4(mids) with a 275amp Mechman H.O. alt with 5 XS power 14 volt batteries. any opinions on the soundstream sc-40CA 40 farad ? http://www.woofersetc.com/p3257/SC40CA--Soundstream-40-Farad-Digital-Hybrid-Super-Capacitor.htm or http://www.woofersetc.com/p3784/SCC1--Lightning-Audio-50-Farad-Carbon-Capacitor.htm
