Im going to be making a new system and im going to be using 4 sundown audio sa 8 v2's rated at 500w rms each what would be a good amp for these im willing to use one big one 2 or even 4 amps but i don't want to break the bank i was looKing at the kenwood kac-9105d thanks!

just did 4 of these on a saz3500 @.5 ..it loud to say the least..id look for a solid 3k if the saz is out of you.re budget

what would you suggest then? it doenst matter to me if i run one 4ch, two 2 ch, or even 4 monoblock amps.

Just remember the 500rms is underated ..I was giving my sa 12's 800 watt daily ..sold to my nephew still giving them 800 watt ..still going 3 yrs strong
They was rated at 600 rms

skippy90210
02-19-2013, 11:49 AM
well 1000 bucks for an amp is alot but considering i was gonna buy 4 of those kenwood amps at 200 a peice an extra 200 bucks would be worth it because that looks like one hell of an amp and what do you mean by @.5?? im new to everything in car audio

NASTY08IMPALA
02-19-2013, 11:49 AM
u only need 1 monoblock around 3000rms id look for a saz3000 or a saz3500 gona be between 5-700 bucks...and need to make sure u got solid electrical to back it up

your not going to find a good enough 4 channel or 2 channel for the price. you dont need 4 mono-block amps for 4 subs. you can run 1 mono amp on all four, just have to wire it right. are you getting d4 or d2 subs?

i would agree to get a solid 3000rms amp. those subs take every bit of 1000 each, just feed them clean power

if u havent bought the subs get 2ohm that way u can wire to 1 ohm at the amp

---------- Post added at 11:55 AM ---------- Previous post was at 11:55 AM ----------

yes get 4 2ohm subs

---------- Post added at 11:56 AM ---------- Previous post was at 11:55 AM ----------

ur also gona need some 1/0 wire a couple good agm batteries and probably a ho alt

skippy90210
02-19-2013, 12:00 PM
so your saying not to buy those subs? if not what subs should i buy? i was looking to stay with the 4 8's idea

---------- Post added at 12:00 PM ---------- Previous post was at 11:59 AM ----------

ya all the wiring and that is no problem to me

QueSound15
02-19-2013, 12:06 PM
your going to be spending a lot in electrical upgrades to be able to power those subs properly. yes get the dual 2 ohm versions if you want to wire to 1, which is recommended.

02-19-2013, 12:07 PM
We did 4 SA8's on a 3500 a few times..works pretty well. If you plan to run that much power though, you need to consider electrical upgrades to go along with it.


I would keep the 8's if that is what you want, but look around the classifieds for a used amp perhaps... You could look at the SoundQubed 2200 or 3500 both will do very well on those 8s.

skippy90210
02-19-2013, 12:16 PM
i will buy a new amp thats not an issue really im just really confused on what amp will work the best with 4 sa-8 v2's

QueSound15
02-19-2013, 12:18 PM
you need at least 3000 watts rms power for those. get an amp that puts out close to that power or more at 1 ohm.

skippy90210
02-19-2013, 12:18 PM
i was just looking at the saz3000 and wired at 1ohm like what everyone was recomending its rated at 1500w is that gonna be too much?

skippy90210
02-19-2013, 12:19 PM
sorry i didnt see your post above so basicly the one i was just looking at is only half the power needed?

Jerhemy
02-19-2013, 12:22 PM
That can't be right...^^^

an SAZ3000 would be a great match for those sub though.

I'm been giving my AS 15's over 1200 watts RMS for almost a year now, don't be afraid to give those SA 8's more than rated.

pro-rabbit
02-19-2013, 01:24 PM
Here is another thing to consider.

You do not need any particular power to run any sub(s). You will need to design the enclosure according to your goals and what power you can safely run. Those subs will work just fine and get very loud in an efficient enclosure with out the need for tons of power.

there is a crescendo 3kwp on here for 450 bucks its an amazing amp and identical to the saz-3k. it as also warrantied at .5 ohm and the warranty was transferable lol. but im sure its over the 2 year. but i would jump on that amp for the price its a steal for you.

and it comes with the terminal blocks from tool maker :)

here are the specs

02-19-2013, 01:44 PM
I wouldnt do 4 of these on a 1.5k they want more power than that. I helped my brother put 2 sa-8v.2s on a crescendo 2k in his car and the have been handling the 2k just fine for almost a year now, not a single problem and they never get hot to the touch or bottom out or anything. Is there a reason youre going with 4 8's? are you limited on space? In my personal experience 8's are kind of a novelty thing. I would only use an 8's if i was limited on space. I think its alot easier to get louder with bigger sub's. Yes 8's can get loud but its much easier to get loud with bigger subs

skippy90210
02-19-2013, 01:44 PM
is there anyone that could design a box for me that would run the 4 subs? i could build it if i knew what to build

skippy90210
02-19-2013, 01:46 PM
yes i am limited on space also all the kids around here are all about 12's and i want to show them 8's can get the job done lol but its mostly space issue

skippy90210

if not would 2 saz1500d amps and run 2 subs wired at 1ohm on each amp work well?

no 2 ohms or .5 ,i have 4 vfl 8's under my rear seat in the z71 truck on 2600 rms and they get pretty loud .you need at least 2600-3500 rms for those subs.i see that you prefer a new amp as well .well dc is having a presale on some of they're amps which will be shipping out the 1st week of march .i can give you a good deal on a new dc 3.5 amp ,and its under the budget that you stated earlier .

skippy90210
02-19-2013, 04:12 PM
im not doing the system right now so thats why a new amp would be easier for me im going to be doing it in a couple of months so you think 2 saz1500 would work fine just run 2 subs on each at 1 ohm

skippy90210
02-19-2013, 04:43 PM
also is there a benifit to run at 1ohm?

skippy90210
02-24-2013, 08:39 PM
would it be a good idea to get 2 cheaper amps of higher watts since cheap amps are like not true like say get two boss 5000w amps or i found this power acoustik amp its rated at 2200 at 1ohm so run 2 subs off of that half of 2200 is 1100 and it wouldnt be true wattage since its a cheaper amp wouldnt it be at like 750w to each sub?

Anything 2k or so would be fine. Find a good deal on a used 2k amp then buy a 3500 when you have the money saved. I will be able to get you a Ampere Audio when they are available if you like. Great Zenon based amp

the only thing is cheap amps usually dont give out the wattage they say they do so what the best bang for the buck brand or the best like off brand amp that will give me close to the wattage it says?

Its a prototype, I think the heat sink is from a rd. The production model will have a different heat sink and certain beefed up internals for greater efficiency! I can tell you Ampere is doing it right before they come to market. A lot of real world testing and a dedicated passionate owner

American Bass Ph4000md 4000w

POWER HANDLING:
◦ 2000W RMS @ 1 OHM
◦4000W Peak wattage @ 1ohm
• NO BASS KNOB AND THERE IS NO INPUT TO ADD A BASS KNOB
• 1 OHM STABLE
• VARIABLE SUBSONIC FILTER
• MONO BLOCK AMPLIFIER
• VARIABLE BASS BOOST
• FREQ. RESPONSE: 10Hz-220Hz
• 4-WAY PROTECTION (THERMAL, VOLTAGE, SPEAKER SHORT AND DC)
• VARIABLE LOW PASS FILTER

there are several people that can design boxes on here, prices from 10- 50 bucks or so.

also I like my aq2200 amp. contrary to popular belief you do not need to over power those subs to get them loud. my amp is only at 2 ohms right now, so my subs are only seeing 5-600 each or so (not quite at rated) and they are loud. I will eventually get 2 more 12's and run them on the 2200. after that i will upgrade to the 3500.

I wouldn't buy a cheap amp or multiple amps. start off with a good 2000 watt amp. then upgrade later. or if you have the cash now buy a 3500 watt amp now.
