US Amp Wiring... ohm load

Recommended Posts

I'm new to the forums... so hello alls...

here is my situation...

I am getting ready to purchase a US Amps IS-2150 amp... which from what ive heard... on average... pushes 715-720 watts bridged peak and 600 rms @ 4ohms... and am wanting to push 3 Eclipse 6103 10's... I currently have 2 of them... which are both 4ohm SVC... the 3rd may be single or dual vc... depending on how i need to do this... or i can have the two SVC's replaced and get all 3 DVC...

my problem is getting the proper ohm load... im not sure how i can do it...

if i run them in parrallel... im looking at 1 or 1.3ohms... which im not sure if the amp i want is stable at that load... and if it is... i have no idea to what wattage it would be pushing...

if i series them... it would end up being a 12ohm load....

so what can i do to get the correct ohm load... i would prefer as close to 4ohms as i can get...

help is much appreciated

-Note-

all stuffed into a 2.5-3cuft sealed box in the trunk of a 99' neon... this could be interesting...

tom? is that you???? ;)

first off, who told you the 2150 can push 600-700w? i dont think even that much underrating can make that possible. Its rated modestly at 480-500w @ four ohms.

anyways, that amp you are lookin at isnt 1 ohm stable, and 3 subs always makes a funky ohm load especially mixing DVC and SVC (never seen that before), it pains me to say it, but i dont think that amp is right for you if you can't get the right vc configuration.

get something that is at is either 1 or 2 ohm stable.

here is one of my sources...

http://usamps.com/is2080.htm

which says 600watts @ 4 ohms bridged... and thats rms... which i can only find 1 or 2 websites stating differently...

here is the site saying typical power is around 720...

http://utopiaaudio.co.uk/forum/viewtopic.p...5ea97d714fefeb4

and this amp is 2 ohm stable.... i just dont know what it would do at 1.3ohms..... which is all i can figure out...

are there any other wiring options that would bring my ohm load up a bit... perferably around 4ohms...

if not... could someone point me in the direction of a 600watt - 800watt 1ohm stable amp... in the same price range ($220) and perferably as clean... >.1% thd

o.. and btw... my names chris

haha nice to meet ya chris just a mod on here (acidburn) is named tom.

hmm thats odd. but the official website is busted. dont listen to it :P . i see also that the other forum has diff numbers as well. Well the numbers i have on this forum come directly from the factory, so i have no idea what is correct anymore. If its underrrated by that much cool, but its better safe than sorry.

yea let me restate that about the ohm stableness. Its only 4 ohm stable BRIDGED. its 2 ohm stable x2 however.

blech i was gonna go say hi on that forum, but i guess not :( its dead

lol... didnt mean to nab ur name...

soo... what about a clean amp that would push those subs nicely...

i am not wanting to run more than 250watts each if i dont have to... i prefer inbetween 200-250 to each sub... and i need it to be clean... i like sq... and i like it to be loud.. and i like how the 10's respond and sound...

someone please point me in the right direction

thanks for the help

question.... if i take these two svc's back and get all three in 4 ohm dvc models.....

would this work to bring my ohm load up to a safer level so i dont have to shell out the cash for a 1 ohm stable amp??

thanks for the help again

-EDIT-

and whats the story on this amp.... Power Acoustik A1000DB is it clean? .5% thd seams a bit high to me...

if you need something 1ohm stable that will push them with a decent amount of power the US Amps Merlin MD1 or AX 1000DE would be more than enough power or Orion 600D could handle the load

i believe im gonna go pick up the dvc models so i can run them at roughly 2ohms...

so here are the amps ive been looking at....

Power Acoustik A1000DB

Lanzar VIBE1800D

not really sure of others.... im wanting a monoblock amp pushing a true 700-800watts @ 2ohms... and perferably <.5% thd... i want it to be loud... but i want it to sound good while doing it... and i dont want to pay out the ass for it either...

those things dont seem to go together well.... lol

Orion 1200D from HCCAfan might be the way to go

well.. the place where i purchased everything is going under... so if i want to swap subs... i have to go through the factory which takes too much time...

so for now i believe ill run just the two tens.... and i think i'll pick up the IS-2150 to push them... right now they are only being pushed by a little EA2212 amp... hardly 100watts a piece max... so i believe the 200 watt per channel rms of this amp... and considering how clean it is... should work nicely until im ready to sell the subs...

thanks for ur alls help... i appreciate it...

this plan will be continued at a later date...

right now the store isnt open...  for some reason or another...  but its $219 plus shipping and what not....      and with 1 year mfg warranty...

question...    is there any way to actualy measure amp output in watts to get an exact number as to what the amp is pushing once its hooked up?

thanks

-AcId-

oh man are you sure they are authorized/legit? cuz rite now, usamps doesnt have ANY authorized internet dealers except www.alteraudiousa.com , and the amps on there are shipped through me, and its a 2 year warranty parts and labor not one.

yes there is a way to measure the amp output...take it to an audiostore and have it bench tested. i would like to know some actual numbers on the i/s's also.

i know of atleast two other places selling the same amp for close to the same price... but i have no idea if they are legit or not... but you alls might wanna look into it considering it may be effecting your buisness...

neways... i definately need some true numbers on this amp... so i e-mailed us to find out a bit more on the subject...

i have a newb question for u alls though... if you mounted 2 10's normal... and 2 10's inverted... in the same sealed enclosure... what would that do towards sq and performance? would phase be an issue? i dont want to adversly effect my sound quality in any way shape or form... but it would look nice... 2 firing at the back seats... viewable when folded down... and two inverted with the motors facing the trunk... of coarse all at angles... with the amp board inbetween... hmmm...

anways...

Mouting will not be detrimental to the sound atall unless the driver's moving assembly itself is noisy. Make sure to wire whatever subs are mounted 180 degree to reverse polarity.

the motors themselves are extremely quiet... so that wont be a problem... just trying to come up with a way to stuff this all in the trunk of a 99 neon... lol
