what amp to get?

[ouch]

i am currently looking at getting 2 x 2ohm subs and want to power them with one amp. what amp specs should i be looking at? mono? 2 channel?

thanks,

go a monoblock dont bother with 2channels cant make as much power as a monoblock for the same price or quality. assuming u have dual voice coil subs u want monoblocking thats able to run at 2ohm stable. heres a diagram on how to wire them assuming u have dvc subs http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=22

yep nice big monoblock will do the job well a higher quality 2 channel will cost more than a big mono i think

[mugen_ctr]

depending on ur sub specs, u than base ur amp specs for it. But make sure the amp power is sufficient to power the sub

Better off getting a mono than a separate 4 channel later on, unless u have big money, than a good 4 channel will be enough, but usually a mono is the way to go to power a sub

try to match the amp rms to the same rms as of the sub, so the power is enough to power it, any less it wont be as powerful as u would of thought. But i hear if the amp is too powerful, it will damage the sub, so bear that in mind as well, and most important tune the sub properly as to not create distortion or cause damage to the sub at some levels.

actually, mono blocks cost from what ive seen, even entry level mono for a decent one is around 200+

[2MPRS]

i powerful amp will never ever damage a sub the way u tune it will. a more powerful amp is always better then a amp with the same ratings as the sub because it doesnt have to push itself as much to create that rated rms, in say that u dont need a 2000watt rms amp for a 200rms rated sub lol

[ouch]

alright well its rated 1200rms, im looking at a kicker one with 1500rms. can i just tune it so it doesn't push as much power - adjusting the gains and such.

[2MPRS]

thats acutally a pretty good combo. set everything to zero adjust gain first then adjust lpf etc then finally bass boost

[trism]

Don't even use bass boost. Quickest way to destroy stuff. Just set your gains to 3/4, low pass filter to about 80Hz, and use the sub level on your head unit for further adjustment.

[ouch]

but if i get an amp that is rated more than the sub, would it matter?

Just admit it, you loved the feeling of outburst.....

[trism]

Not many people can unleash a shitstorm like we can Bludger.

[ouch]

boys boys boys, if im going to run about 1700rms, do i need more than a deep cycle battery? (eg, 'the big three upgrade' or an alternator? do i even need a deep cycle battery?

[ouch]

i also want to get 2 different components.

1. boston acoustics pro60se - 3ohms - 125rms
2. rockford t3652s - 4 ohms - 125rms

does it matter if the two speakers are connected to the same amp but have different ohms?

[TbM]

If you are planning on running them on a 4 ch amp then you just have to make sure its at capable of running 3 ohm speakers, the lower the ohms the more stress it puts on the amp so if its 2 ohm stable then you will be fine running 3 ohm speakers but if its only 4 ohm stable you may need to look at different amps that are capable of running lower ohm speakers.

You can connect different speakers to an amp so long as you not running lower ohms than it can handle it doesnt care what speakers you have connected.

says it can run

Per Channel into 4 ohms: 100 W x 4
Per Channel into 2 ohms: 100 W x 4
Bridged into 4 ohms: 200 W x 2

so should be all good to run 3 ohms at 125 rms? or no?

[TbM]

Yes but it will only give it 100 RMS each channel, I generally prefer to overpower my speakers rather than underpower if the budget permits it.

will this do me well?

[TbM]

Out of the 2 you have selected i would prefer to run the F6 over the F4 and just make sure you dont have the gain turned up too much.

[ouch]

cheers mate! rep to you! now get some sleep.

im planning to get those two components and 1200 sub with a mono (pdx m12) - so thats 1700rms.

what should i be looking at to do/get in regards to power supply?

[TbM]

Lol thanks mate. In regards to the power supply it depends on how hard you plan on running the system, if your goin to be running it fairly quiet then you may not need to upgrade the alternator but if you are going to be running it full volume then you will be drawing more upwards of 100 amps(cbf working it out now) which your alternator will not be able to supply. For example i think my ek alternator only does 60 or 80 amps IIRC so running a system like that at full volume would require a better alternator to support the system. If you upgrade the alternator you will need to upgrade the wiring from the alterantor to a higher gauge cable depending on how many amps it puts out.

[ouch]

ok guys guys guys, planning to get speakers first and see where money takes me from there. but im looking at either two pairs of boston acoustics pro60se or two pairs of rockford fosgate t3652s. any opinions or comments about these speakers? and what amp!? :D

[tron07]

Do you like apple?? Get a mac. 600X1 @ 2ohm

At this stage your best bet will be to go and listen to the speakers, we can tell you what we like to listen to but that may be different to what you like. Once you hear the speakers you will be able to decide which you like better. IIRC there is a shop in nsw called Fhrx which is meant to be quite good so maybe look them up and see if they are close by then go have a listen to see what you like. Try and listen to some focals and morels if you can, great speakers IMO.

Whats your budget?

[ouch]

Me budgets about 400 per set. Want to grab one for the front one for the back. Plus an amp for now. Subs can deal with later. I think I might just stick with the rockfords. My mates have the t2s, the older versions and from what I've read and heard the t3s are a totally different product and blow the t2s away.

Now the problem is what amp to get? I was thinking the pdxf6 but it is a class D amplifier. Should I be looking at AB amps?

[TbM]

Reading doesnt help buy you the right speakers, listening to them does, i still recommend you go and listen to the speakers before you buy them so you know what sort of sound they produce.

The other thing to consider is do you need 2 sets of speakers. you can quite easily get away with only running a front stage(Front splits only) which allows you to spend more on the speakers you will be listening to. I run my car with a front stage only and its still got enough volume to hurt your ears so unless your after something ridculously loud then its something to consider as 2 ch amps are cheaper and use less power.

Regarding the ab vs d class amp, d class will do you fine. They are quite good these days.

Have you budgeted for any sound deadening? Would recommend you atleast do the doors that your splits are in.
