Dual Sub question

[JonnyDe]

I got a quick question for anyone who knows about subs and amps.

I have just bought a VE Sv6. And i am planning to put two subs in the boot. I am going to make custon boxes to put one in each corner at the back and mount the amp/amps in the middle.

Now heres the question, should i buy 1 big two channel amp, or two smaller mono amps?

i know that i will need either a 2 channel LOC or get High Inputs on the amps.

G'day mate

any chance we could have some details of the subs? That way we could work something out for you.

[holdenboy]

Generally, one monoblock amp will be better.
* Easier to install
* Less wiring
* More than likely cheaper

But in saying that, if you want a nice symmetrical design in the boot then maybe two monoblock amps.
Whatever you do, make sure the subs you buy are suited to the amps (impedance wise).

[StoneX]

Just buy a mono with enough power to run both subs and make sure you buy the correct models to match the amp.

[StoneX]

Wow, there was no replies when i started typing.

Im running duel subs on a 2 channel amp
Subs are pioneer 1200 watts each 450rms
Amp is 500 watts.
Also running another amp to my 6x9's (just bragging here )

But if i had money to spend i would definitely buy 2 mono amps and hook up a sub to each.

[JonnyDe]

well, i dont have the subs yet, so im open to ideas. all up I dont want to spend over 700.

im thinking dual 12's. I was thinking of just buying one really big Mono block and sticking it in the middle. but how do you wire two subs to it. Do i just run it in a parallel circuit?

[holdenboy]

$700 for 2 subs and a monoblock?

Depending on what subs and what amp you get will depend on how they are wired. Lets just say you get 2x 12" 4 ohm DVC subs and a 1 ohm stable monoblock. This means you join the two +s and the two -s together from sub one, do the same with sub two and run the wires from each sub to the amp. This will give you a 1 ohm load for the amp.

holdenboy this is my first post can you helpme out i have a sony sub 500wat 12 inch other sub sony 1500watt and a sony xm1502sx 2 channel amp can it run these woofers ? your help is appreciated:

[JonnyDe]

yeah, 700 all up is the max price. if i can get a good deal than that would be cool. Was looking at the Edge 12's from shopping secure. but open for surgestions.

[holdenboy]

OK well thats a tight budget for 2 12s and an amp to run them.
Anyway, cant really go past the Pioneer's for value, heres some on Ryda as an example:

Ryda Car Audio - Pioneer TS-W308D4 12" 1400W Subwoofer($178.85)

So thats ~$350 for two 12s, they are available in either dual 4 or 2 ohm voice coils......so dual 4s will need a 1 ohm stable monoblock, dual 2s and you can do some nifty wiring to get 2 ohm.


Kenwood 9014D, a favourite of mine for value, does over 900w at 1 ohm:
Ryda Car Audio - Kenwood Car Audio KAC-9104D Car Amplifier($348.85)

If you want to stick with Pioneer for the amp, then the only option with the money left over is the D8400M, only makes 600wrms but will still push those subs ok:
Ryda Car Audio - Pioneer Car Audio GM-D8400M Car Amplifier($358.85)

Then youve also got Joe's site (shopping secure), with more options again

[JonnyDe]

Well, if 700 is a bit low then i guess we can go to 1000.

Its not gonna happen right now. will have to do some saving. I just wanted to know if it was better to go with dual amps or a mono block. SO far it seems that its best to go with a expensive mono block.

[holdenboy]

Yeah mate definitely a large single monoblock.....does the $700/$1000 include wiring and installation, or are you going to do it yourself?

Your subs need 900wrms together running off a 500watt max amp?

[JonnyDe]

Il do it myself. I have already wired up one in my previous car. And im a 2nd year apprentice (at a holden dealer) so i have basic electrical knowledge.

I just dont really know about sub and amp compatabilites and that stuff. And if rather go with something different. Soundstream, boston, Rockford fosgate, Vibe, Edge. That kinda stuff. cause everyone around my area has pioneer or alpine.

i dont care too much if its not the loudest system, i just want a good quality one. But i do want dual's

[holdenboy]

Fair enough, i can understand you wanting something different but high quality.

Look into Joe's gear then.....maybe look at the Vibe Slick 12s, single 4 ohm coils (so 2 ohm to the amp), Joe will be able to do you a better price also.

As for an amp, if you want to stay with the same brand, the Vibe Slick A7 is suitable.

So thats a total of $1300, but im sure Joe could get it close (or on) to the $1000 budget.

Theres not much info on those EDGE subwoofers, so i cant say what amp would be suitable. Theyre probably 4ohm SVC so the same as the Vibe subs above. Anyway, an amp to suit based on my assumption would be the Option Audio OAX801, has 500wrms of output at 2 ohm so a little over.kill but thats fine.

That would get you well under your $1000 budget, probably closer to $600-$650 if you twist his arm

[JonnyDe]

Sweet, I think il go with the Edges. I really like the orange subs. And saving a bit of cash is always good.

Next month i become a third year apprentice. so i will actually be earning a living

So around march sometime i will be making the order. Im sure within that time i can attempt at twisting Joe's arm

[holdenboy]

haha, yeah he'll take some $$$ off if you buy the subs and the amp from him (tell him i said he would haha).

[JonnyDe]

Just another quick question, Do you know if that Option Audio Amp has High Level speaker inputs. as I got a VE. I can always just buy a LOC. but thats another 100, and if i can get a better amp for 100 more than i think that would be better.

[holdenboy]

No, not by the look of it. Usually an amp with high level inputs will have a plug near the RCA inputs. That amp dosent.

The Cache LOCs are good quality units, far better than the high level inputs on most (if not all) amps. Plus those LOCs have signal sense, so they turn on (and the amp too) when music is on, from his site:
All of the Cache models feature a signal sense feature which allows them to activate as soon as you turn your head unit on. All the models also have a remote output which activates the amplifiers when the LOC is activated
They also have a clipping (distortion) indicator....handy when your tuning the amp

[Timboy]

So long story short (I'm gonna throw my query in here to make sure I don't start a new thread), I could run twin 12" type s alpines off a monoblock amp?

Yes, you can, but you will need to find out the impedance levels of the amp, to determine the wiring configuration of the subs.

[Timboy]

Impedance?

I'm running a cadence 1000w max and wanna power 2x12" Alpine Type S subs which are 350w each i think. Not sure if that's rms or max, but i'll check after I pick em up. If I get them and need a more powerful amp, I'll go buy one, but hoping that I don't have to do that

[HCVP]

If you give me the exact model number of the amp, i can draw you up a wiring diagram of how you will need to do it.

[Timboy]

FXA 1500 I think.

Type S Alpine's, not sure exactly power or anything cause I don't have them yet :P
