ok, so i bought this sub, but am not sure what amp i will need to go with it.

I am looking for an amp that i will most certainly not blow my subs with, but will power them well, and hopefully something $150 or under. If you have any suggestions please leave them. Thanks

At that price range, you don't have much choice. Audiobahn/Hifonics/MTX should have something around 400w @ 4ohms. Audiobahn's A8002 sells for $150 or less. It'll give you 400w - 600w @ 4ohms.

Thanks Isaac

So what would you recommend for an amp (wattage wise) Regaurdless of the brand for the subs. Again, something that would not blow them, but would give me good power.

And i would need a mono amp right?

Your subs are 400w rms, so I would get 600w - 800w amp. That way you can upgrade the subs in the future and not worry about the amp. Don't worry about the power mismatch. It's better for the subs cause 800w amp pushed 50% will produce clean power vs 400w pushed to the limit.
Mono class D amps are cheaper than 2 channel class AB.

ok so i need a mono amp of some sort at 600-800w. i'm most likely not going to upgrade the subs, so do you recommend the 600 700 or 800 w?

And i do have a power wire from my battery to the trunk, but it was for a 500 wat amp...will it work fine with a bigger amp, or will i need a new wire?

i am looking up subs on this site and can't seem to find many at all at 6-800 at 4 ohms... can you recommend any? I guess i'm looking at $200 or less now. again, i'm not gonna upgrade so i basically want an amp as cheap as i can, but one that will power my sub, and not blow it, and get the most out of the subs i have. Thanks again

Are you looking for subs or an amp? Your last post sounds like subs.

For an amp, this one should work:

yeah sorry...i meant amps. So this will give me 800 watts at 4 ohms or 400 at 4 ohms?....just asking because one review said "800 watts X 1 @ 4 Ohms"

P.S. I like the amp you suggested. Are their any problems i have to look out for when i bridge it?

And are there any mono channel amps you can suggest?

Before i go into the amp, i gave you the wrong link to my sub. It is pretty much the same only 12 inch subs. Here are the link and specs:

- 400 RMS Power
- 800 Peak power
- 4 ohm nominal
- 92 db @ 2.83/1m
- 48 - 150 Hz

link - http://www.crutchfield.com/S-muwcyfSRWdf/cgi-bin/ProdView.asp?g=510&I=236RT12X2A




I believe this is the amp you suggested at a great
price.

http://www.techronics.com/index.cfm?fuseaction=product.display&product_id=120&gc lid=CLeZ7__o_4kCFShSPgodax6rSQ

So you think this one will do?.... I just want to make sure, because i don't want to mess anything up. I'm not sure if the subs are wired in series or parallel.

Austin, how good is your self control? If you can manage to keep the volume down and now blow the subs, then that amp will work fine. If not then try this model: http://www.techronics.com/index.cfm?fuseaction=product.display&Product_ID=3939
That amp is 400w @4ohms and 800w @2ohms. Costs about the same.

I want an amp that i will def. not blow my subs with. i probably won't have good self control...lol

i'm confused though. please help clarify this if i am wrong. I have a 2 sub setup. Each sub says 200 watts at 4ohms on them. Since they are wired in parallel(i believe) i need a 2 ohm amp? And however much an amp pushes(wattage wise) that will be split in 2, half going to each amp??

I just need clarification on what ohm i need to be looking at for my setup, 2ohm or 4 ohm, and possibly an explaination of why? And how much power(wattage) i need going into my sub box to power my subs sufficiently enough to sound good, but not blow them by cranking it up.

Okay, if your subs are 4ohm DVC, then you need the last amp I posted, if however, it's 4ohm SVC, and you can't get it exchanged for DVC, then go with the first amp link. That will give you 200w x 2 = 400w. So you're still good.

I'm fairly certain that my subs are DVC. I was looking at reviews of the sub and ppl posted mostly amps that were around 400w @ 4ohms. So i guess i will go with that and hope it is correct.

Now i just want your opinion on the amps i have looked at.

This one would be great because even if i am wrong about the SVC DVC thing, i get the same power to my subs. http://www.techronics.com/index.cfm?fuseaction=product.display&Product_ID=1654

Then there is yours: http://www.techronics.com/index.cfm?fuseaction=product.display&Product_ID=3

What do you think, or suggest any more under $200
I'm looking for quality mostly. I don't know which brands are better than which. I want something that will last me for a long time.

That amp is only 400w. In terms of quality, I'd rate them about the same.
For about the same amount of money, you get more power, therefore I'd get the 2nd amp.

One more think, remember what I posted, if it's DVC, then A8000T is a better choice, if it's SVC, then 8002 model.
Again, if you have some self control, get A8000T cause it's class D amp, meaning it uses less power.

Ok now i am confused. Both the amp i recommended and the one you recommended say 400W @ 4ohm, so how will yours give me more power??

So here is what i am getting out of this. I Need 400W at 4ohm to power my two 200W subs.

I don't know why you recommend the Audiobahn A8002T 2-Channel Amplifier because that is 800W at 4ohms.

However these three will work for me:

http://www.techronics.com/index.cfm?fuseaction=product.display&Product_ID=3939

http://www.techronics.com/index.cfm?fuseaction=product.display&Product_ID=3

http://www.techronics.com/index.cfm?fuseaction=product.display&Product_ID=1654

And the last one will work for me if it is the case that my subs are SVC and not DVC....Am i right?

You're only looking at current setup. What happens if you need more power in the future? Are you going to dump both the amp and subs? If you buy an am that's more powerful now, then you won't have to play double later.
A8002T is 2 channel amp that is 800w @ 4ohms. However, if your subs are 4ohm SVC, they'll get 200w x 2 = 400w. Same as the amp you were looking at. If they're 4ohm DVC, you can still get 400w by using only one channel. Better choice would be 8000T cause @4ohm, you get 400w and 800w @2ohms.
Does it make sense now? The output power will depend on how you wire the subs.

my bad on the repost....

This does help, but now i have another Q. Wouldn't the Audiobahn A8002T 2-Channel Amplifier be the best choice out of all of them? Because if my subs are 2 ohm, then i can hook up one 400W to my subs to power them, and have an extra 400W @ 2ohm or 200W at 4 ohm available for anything else. If my subs are 4ohm, i can bridge the 2 hookups and get 400W for my subs. Or if i want to upgrade i have 800W at 4ohms available(if i removethe currnet sub)

Since the Audiobahn A8000T 1-Channel Amplifier is a mono amp, i am screwed if my subs are 2ohm because they are only 200W and i would have double the wattage powering them and they would most likely blow. I don't think rewiring the subs is an option at the moment. I guess i'm not sure why you think that the A8000T would be bettter, when i can get the same power out of the other one and have more options( unless the A8002T is not bridgable?)

I'm gonna try and see what wiring setup my subs have. I did make a diagram, but i'll compare it to this site to see what ohm load they are set up for.

I've personally tested A8002T amp and it performed well during ice oold winter. The reason why I was pushing the 8000T was, it is class D amp, meaning less power for ame output.
Since you are not sure what the configuration your subs are, 8002T might be the best choice.
If your subs end up being 4ohm DVC, you can still use both channels on 8002T amp by looping one of the VCs.

Thanks for putting up with my ignorance Isaac. It all really helped...If i have any other Q's i'll get back to you. The first thing i'm gonna do though is find out how my subs are wired. Thanks again.

Alright..this should be my last question Isaac

I'm positive my subs are 4ohm DVC.

So, of these three, which would you recommend, and what are the pros\cons of them?

1.http://www.techronics.com/index.cfm?fuseaction=product.display&product_id=120&gc lid=CLeZ7__o_4kCFShSPgodax6rSQ

Thanks

I just keep thinking of more Q's for you...sorry.

can you recommend a wiring kit too...there seams to be so many out there at different prices that i have no idea where to start. Thanks

Austin, there aren't much difference in those amps. I'll break it down for you.
A8002T is a class AB amp.
It does 200w x 2 @ 4ohms
400w x 2 @ 2ohms and 800w x 1 @ 4ohms bridged.
This amp will eat up more current than class D, however, it can be used to power subs and full range speakers such as the fronts and rears.

8000T and 8000V are the same, one is the old model and V is their current one.
It's suppose to be class D, meaning it will use less power to produce same output.
400w x 1 @4ohms and 800w x 1 @2ohms. If you plan on using the amp strictly for subs, then get 8000T or V cause it's better suited for it.
If you match the ohms with the amp's requirment, then it'll be pretty hard to blow subs.
For wiring kit, don't go overboard, usually the $40 kit will perform as good as $150. The only difference is the strand count. Once you get to 1000+, they behave similar. So don't get suckered into spending large amount of cash. If you can, go with the thickest cable, 2 - 0 gauge wires. That way, you're covered for future upgrades.

Hey isaac, i have another Q for ya.
I'm trying to order he audiobahn 8000T but it was sold out of where i was trying to buy it from. Then i thought, since both the 8000T and 8000V are pretty much the same should i get the newer one? Will the newer one have more "kinks" in it? I'm not sure what the advantages would be for the new one over the old one. I have seen MANY reviews on the onld one and ppl love it. Only one bad review out of 50 or so. I can't find any reviews on the new once since it is new. What do you think?

oh, and another thing. Will i have to worry about drain on my battery? If so would it be better to switch to a whole new amp all together, maybe a D class?
