Help me with an amp!

[Link_T1nks]

I am about to buy an amp for my rockford 12" HX2's and need to know first which would be better. Will a 800 watt bridged amp connected to both subs, or a 1000-1200 watt split in two channels to each sub be better? And will bridging them and connecting them to both subs wear out the amp? I'll prolly be getting a rockford amp too. Just wanted to know.

[Slim ThuG]

is it the reg hx2 or power hx2....my suggestion would be a bd1000 amp or something around there....ask AKAPSYCHO...he can help more...shoot him a PM:thumb:

thanks

It's more complicated than that, yo need to know the impedence of your subs. They're dual coil, so what each coil's impedence (ohm load) is.

Chances are they're the dual 4ohm, as I think that's the most common HX2 config. IF THAT IS THE CASE, then you will be wiring them to the amp at either 4ohm or 1ohm final load. That said, if you get an amp that does like 800 at 2ohm, and you're at 4ohm, you aren't getting the 800 watts obviously.

Find that out, akapsycho will ask the same question, because you can't pick an amp out without that information.

I'm kinda new...Who's AKAPSYCHO???

[Link_T1nks]

The subs are dual 2 ohms

[redricerocket97]

well if they are 2 ohm, if you get a 800 watt and bridge it to both subs, the amp will problly keep kicking into protection mode whene you turn up the volume. so i would go with the 1000 watt rockford and run one sub to each channel

[redricerocket97]

dont ask me how i know this;)

[Link_T1nks]

HAHAHAHAHAAHHA!!!! alright, thanks.

[redricerocket97]

no problem :thumb:

He said they're DUAL 2ohm, you can wire each sub to an individual 4ohm load, then parallel the pair of subs for 2ohm total. Most all mono-channel amps these days are at least 2ohm stable, if not lower..

but of course you have to read what the amp says...some ppl see 2 ohm sterea and think they can bridge it at 2 ohms...if it is a 1 channel amp or it says 2 ohm mono...then you will be able to wire it like that



and as far as the hx2 DVC 2ohms go...if you get 2 12's I would go with the bd1500...I have done this in a ported box...(make sure it is built to spec...punch subs LOVE to blow ther cone in the wrong box) and it hit really well...a bd 1000 puts about 700-800 watts at 2 ohms...and you have 2 1200 watts subs...if you are still look'n for amps...I would go with 2 kicker 1200.1 and strap them together...2400 watts.

[dak4.7]

Yeah, I prolly should have said that, since a lot of people take bridging an amp lightly.

And if you're a broke ass mofo such as myself, a pair of JBL BP1200.1's wouldn't be bad either.

Are they the punch or the power HX2?

[Link_T1nks]

I've been reading the manual, and it says i can bridge both the subs together to get a 1 ohm load, does this mean that i can still get the 1500bd and not blow out the subs? Cause the 1500 watts are for 2 ohms, and I'd be connecting the subs at 1 ohm.

[dak4.7]

If it's dual 2ohm (meaning, each coil individually is 2ohm, for a total of 4 2-ohm coils) then you can't wire it to 1ohm as a pair. You can wire each individual sub to a 1ohm or a 4ohm, but the PAIR combined (which is how it would have to be on a mono-channel amp like the BD series) is back to 2ohm.

So, if your subs coils are EACH 2ohm, then the bd1500 will be fine. And also, not that this really matters but just for your own knowledge, if you run the amp at a lower impedence, like running it at 1ohm rather than the rated 2ohm as you mentioned above in your post, you're more in danger of hurting the amp, not the subs. The amp is the one that will overheat cuz of too low a resistence. The subs would get more power, yes, but probly not for too long :) Also, many amps, when you go lower than their minimum rated impedence, don't put out that much more power anyways (it doesn't double like when going from 4ohm to 2ohm on most amps does) so again the subs wouldn't be in much more danger.

If your subs though are dual 4ohm, you can wire the PAIR to a single 4ohm or 1ohm load, OR, you can use a 2 channel amp and wire each of them to 2ohm)

800 watts only for the BD1000?:roflmao:
where are you getting these specs at? LOL

BD1000:
rated power: 1000x1@2ohm
benched: ~1300x1@2ohm

BD1500:
rated power: 1500x1@2ohm
benched:~1700x1@2ohm

:)

[SRT]

don't install it by yourself of you will end up like "x" who lives in Nacogdoches.

show me a birth certificate that says that.

[Link_T1nks]

wouldn't u burn out the amp if u benched it?

[Link_T1nks]

I found out that it was a 4ohm sub, not 2ohm. So now, I know I can wire it into a 1ohm load. Will the 1000bd be enough for it though, or will i have to go for the 1500bd? Or shoudl I go for a kicker KX1200.1?

[akaPsyco™]

punch amps don't like 1 ohm loads...kicker would be better at it...but it still is rated at 2 ohms...

if you want to run it at 1 ohm I would go with a JL1000/1 ...they have regulated power suppies...so that means that it doesn't matter what ohm load you run it at it will still be about the same wattage out the amp...you will get like 50 watts more if you run it at 1 ohm instead of 4 ohms with a jl amp.

[dak4.7]

I wouldn't risk running any of the RF amps at 1ohm, they're current hogs as it is, that's just asking for trouble.

And aka, my BD500 birthsheet says 718@2ohm, that good enough?

Back to you links, the JBL BP 1200.1 is 1ohm stable (still puts out just barely more than the 2ohm rating, but will last just fine at 1ohm and is pretty well priced too.

fuck all that bullshit
Studio series memphis
memphis ST-1000D monoblock
digital amp (doesnt need very much current at all)
D class
1100 watts @ 1 ohm mono RMS
600 watts @2 ohm mono RMS
and 300 @ 4 ohm mono RMS

Power Reference series
Memphis 16-PR1KD 1000 watt mono block
D class digital amp
1000 watts @ 1 ohm mono
600 @ 2
300 @ 4
all are RMS

i still believe it would be alot easier just to get a two channel, cause then he could get the amp he wants and not havto worry about OHM loads. my final vote is the bd1200 two channel

[Link_T1nks]

Can anyone tell me how good planet audio is? Which is better? The planet audio PA 1200D, or JBL 1200.1?

same thing I was thinking.....rockford only makes the bd series one channel, right?

As far as I know, and as far as their site suggests.

Not sure if anyone else uses the bd name for a line or not though..

i would personally get the PA 1200D amp. crossovers are MUCH better than the JBL's. JBL is great for raw power, but if you don't have money for external processors, get the PA amp.

the best deal i have seen right now is the Better Audio 1600M1 amp. $325 shipped for a class D amp.

1500x1@1ohm
1000x1@2ohm
500x1@4ohm
18db Octave LP filter
24db Octave Subsonic filterRemote Gain Control
Clipping, Speaker Short and Thermal Overload Protection
etc...


seems like this is the new bang for the buck amp:P

Shame on you! That's almost as bad as drilling thru a trunk floor into a gas tank for a ground. Almost..:thumb:

I work at Solor Systems off west mount houston and sweetwater...I do installs still...but most of my work is out my garage..."Moble Two"...LOL...I am work'n on a 90 civic and I will have pics of it up soon...two 12 alpine type r's...

did that too...but that was on my own car and I was 16...I learn from my mistakes..."look before drill"

[tkr_prelude]

lol.....

[spikerman]

we made sure when drilling on my car that it wouldn't touch the fuel tank. I didn't want anything to explode if the gas was sloshing around and hit a ground wire...

[dak4.7]

I don't think it would explode from touching ONLY the ground wire.

hehe if the car was full of gas fumes and it arced....BOOM =)

Go drive your prelude..:gay:

What you and your amp do in the privacy of your own home is none of my business, and I think that belongs in Los' Lounge :P

[240sxboi]

lol shut up hahah

memphis is the shit
