I need help finding an amp for my subs

[stainless]

I bought 2 Alpine Type-R SWR-1242D subs and now im lookin for an amp to push em. I want to get 400 rms out of em at 2ohms..... is that right? I really have no idea what i'm talkin about, just going kinda by what the best buy guy said.



I bought an idiotic amp NEW HIFONICS 1200W BRUTUS BXi1206D that isnt powerfull enough for my subs so now I have to resell it.... putting it up on ebay prolly but if anyone wants it im trying to sell it for 210 shipped

So can someone please just help me out, Im trying to only spend about 250-350 on it if thats possible....

Dude, I'm not going to say HiFonics makes quality stuff any more... But if that amp wasn't capable of putting enough power out to your subs for your liking, then I don't know what will in the financial range you are looking at...

How did you have your subs wired? If you parallel/parallel them, they will produce a 1Ohm load, which is what that amp needs to push it's full load. If you wire them at 4Ohm (one of your other options), you will only be seeing 450Watts TOTAL!

Before you continue, MAKE SURE you had your subs wired correctly!!!

Ummm.. those subs are dual voice coils meaning each sub will be running 2 OHMS each- so if you have 2 ov them- you're looking to go 0/1 ohm capable amp. It'd have to be at least 1000w mono-block (one channel) and an external capacitor. I usually run with Memphis- good price and is right up there with JL. (Memphis PR/ST/MC) mono blocks go for about 300 on eBAY.

so the amp I got for my subs will work? I havn't installed anything yet but I was under the impression that the amp wont be powerfull enough for my 2 subs... here are the specs

450W x 1 @ 4 Ohm
900W x 1 @ 2 Ohm
1200W x 1 @ 1 Ohm
S/N Ratio : >95dB
THD & Noise : <0.08%
Heat Sink Dimension : 11.41" x 2.63" x 10.39" LHW

it says 900W x1 @2 Ohm.... so does that mean I can "bridge it" (i think thats the word) and make it 450W per sub at 2 Ohm?

so what exactly would you suggest I say when I go to have it installed, I'm very new at this.

But then again if it's just not going to be loud and bumpiun, then ok I will resell it and buy something bigger and better... lets say I have 350-450 to spend, then what would you suggest to be able to get to use the full potential of my subs?

thanks !

Your subs are Dual4
Wire them like so


Then wire them into your amp, in the bridged terminal (one on each + and -)
You will get the 1200w, wire down your gain since your subs are only 500, you should be set...

Loudness will also depend on the type of box you build, ported or sealed, ported if youve got the space...

[theprodigy79]

Yes. As wood stated, if you wire your subs voice coils in parallel, then both subs together in parallel to the amplifier, the amp will see a 1Ohm load (which will bring it to its max output of "1200" watts, meaning each sub will receive about 600 watts). The Type Rs are rated at 500W RMS, however they can handle more comfortably (I have a pair of 1222Ds that I was running on an oldskool Soundstream Class A 10.2 pushing AT LEAST 550W to each, real power RMS, and they did great).

You'll be fine with the Brutus for power... Just make sure you build a good quality box. Your subs are great, get the most from them.

thank you all for your help, I really appreciate it.
just one more question, what set of wires do I need?
will these work?

I dont see why they shouldnt... but I just wanted to ask, heard knuKonceptz was a good brand
?

thanks
I will be sure to post pictures of the final set up once I'm done.

Is this the only amp you are going to run? Do you have plans of adding a second amp in the future? If so, 4awg is skimping a bit... You may want to consider 0/1awg, or at bare minimum 2awg (if you can find it).

[stainless]

why would I need a second amp? Thought mine pushed plenty of power to my subs.... If it dosnt I would just like to return it and get a new one... i dont plan on getting two

[theprodigy79]

Plenty of power to push your subs, yes... But music ain't all about heavy bass and no mids/highs... I was speaking in the case you ever decide to amp your "full range" speakers.

It's all good man.. If you just want the bass, then 4awg will do you fine. But if you ever decide to balance out your system and add some quality to the upper range you'll have to rewire the power.

[.onetohate]

usually- well for the most ov us anyways.. we push our mids and highs with a multi-channel amp...as opposed to the stock deck or aftermarket deck- it just sounds better and less stress on the deck itself. 1 amp is for subs (one you already have) and 1 amp for speakers.

[theprodigy79]

For example, check out my two most recent setups (the Supra being my most current, and my Solara before I stripped it).

Both setups aim to achieve two COMPLETELY different goals, however notice in both that I have my mids/highs amped AS WELL as the subs.

Solara:

Full fledge "competition" setup.

Supra:

Much more simplified in favor of keeping additional weight at a minimum and reducing power draw. Using the 604 (a 4/3/2 Channel Amp) I am powering my front stage speakers and a single 12" sub. It sounds simply awesome.

OOOOOH.... thanks for clearing that up.... it all makes sense now lol... Thanks everyone for your help !

FYI. Type R's can take about 1000 watts daily and be perfectly fine so there is NO concern with overpowering them. Also for your amp the Hifonics amp ratings tend to be a little overated so your probably gonna get more like 1000 watts out of it at 1 ohm so it will give you the power that youre looking for

[indiglosolara]

I have a Orion Amp that can push these subs with no problem..

The amp is NEW.. so if your interested let me know.
