Which mono sub amp ?
 

Which would you choose and why ?

ARC Mini 500.1
Zapco Reference 500.1
Sundown SAX-1000D
JL Slash 500/1
Digital Designs CM1


Any others I should be looking at ?

I would use "non" I would get a 2 channel amp instead that could handle the power you require, they're more versitale. But if you insist on a monoblock, the Sundown Audio looks like a good choice for the money.

which 2 channel amps can handle a 2 ohm mono load , with about 500-700watts ?

Sundown Audio because I am biased.

i would look at the sundown or DD being that they have the most power, but i don't think thats a good way to look at it.

I dont need 'the most' power.. Im only running 1 old skool 12" kicker solo.
Also, a high damping factor rating is good for running subs no ?

Sundown, I'm with Jalat on this one, I'm also bias.
I have the SAZ-1500D and a 12" Nightshade in my beater.
And I have 2 SAX-100.4's in my basement waiting to go in the Sentra.
Just saving up for a pair of SAZ-3500D's

Damping factor is low on class D amps.. Class A/B (zapco) have high Damping, which make for great SQ and control on subs ! Thats why Im undecided yet ...The Class A/B puts more alternator strain though..

sundown audio all day man! check build log they are sexy! plus i think ther is 1 in the for sale section!

you are talking about subs right? and damping factor man don't even worry about stuff like that, that is jsut a gimic kind a like pre-out voltage!

you will never hear the difference in damping but you WILL pay for it!

also some more stuff on sundown audio if you are interested

i also look at it like this! A/B = speakers like components and class D or T are subs!

i have a sax100.4 pushing my zapco RB13.2 and man o man they shine like you woudln't believe!

I probably wont hear the difference, but good damping helps the speakers...

Thanks.. already seen the sales on DIYMA.

here give these a read and you tell me about damping factor

dont' get caught up in the damping war! it isn't worth it! your pocket book will thankyou later!

seriously though what are your GOALS?

Ive read alot already on damping factor.. its not only that, THD is crucial as well.
Class D amps are a compromise.. smaller, more efficient and cheaper.

but read this ...

if you look at my sig, Im into SQ not SPL...lOl

THD lol

A THD rating < 1% is considered to be in high-fidelity and inaudible to the human ear.

keep that in mind! but like i said WHAT are your GOALS??

if you are worring about the nit pic things are you a all out SQ guy? or is somebody who has a little knowledge whispering in your ear? lol

Seems like you know enough to choose an amp!

You state you want a high DF, low THD, class AB, 2ohm stable subwoofer amp...so you know what you want...shop till you find it!

^ that pretty much sums it up, lol. seems like you answered your own question rob.

personally i'd say they are all respectable amps, you aren't looking for a huge amount of power => stick with the zapco. you are already running all zapco, why switch it up?

if you are going for a stealth install go with the arc, you can hide those things anywhere.

Yeah gotta agree...sometimes you just need to have it all out there to help you find out what you really want...glad we could help!

Have a look at the specs on the ARC KS300.2. It's a 2 channel amp that will give you 700w bridged. :)

^^not 2ohm stable in bridged 1 channel mode....these are though:

Dls a2, 450 watts @ 2ohms, class ab, df >200
rf power t-5002, 500 watts @ 2ohm, class ab (older model may not be available now)
rf power t-6002, 600 watts @ 4ohm or 2ohm stable, class ab
zapco c2k3.0x, 665 watts @ 2ohm, class ab, df >1000, thd .015...but pricy!!

wow. that's more like it...but it doesnt do 2ohm mono..look at the amp

according to their website it does...but I think it's a typo as their manual says @ 4ohm...oh well, the other 2 will though. The RF I know for sure as I've owned a few of those...great amps! Never used theat DLS, but they are reputable, so I expect it to be very good.

Thise new zapcos all have balanced inputs.. no RCA's ???
