Hi guys..

I got a question:

I am running a single 300w RMS Earthquake subwoofer off a Coustic monoblock 400w Amp.

Right now the amp is not bridged but the sound is very good (in my ears).
Would I have any benefits in terms of sound quality if I bridged the amp?

The reason I dont just do it now is that i have covered up the whole setup and dont want to pull it all apart again for nothing.

Any ideas?

ermmmm you cant bridge a monoblock amp.....hence the reason its a monoblock, its only 1 channel.

u sure? the amc member I got it from said I can....and he did too

EDIT : its got 4 outlets

i was always under the impression a monoblock amp is 1 channel.....so a 400w monoblock, is 1x400w..........not like a 2/4 channel amp which could be 2x400, or 4x400....which are then bridgeable.......

someone confirm, this will show my extent of car audio knowledge....lol.......

lets see....I am at my end -of-knowledge too.

PS - coolest image in yer profile, bro...Choice!!

i dont think they can be bridged.

i think its just giving the option to be split or not, like cutting out the work of wiring in 2 subs to 1 pair of outlets.

i was under the impression mono - 1
but when i got my jaycar mono it has 2 outputs, so yeah, i think its just versatillity.

someone else will make better sense of that though:P

Chantra, you can't bridge it. And it wouldnt make any diff, so just leave it :) Hows it sounding though man? Are you half deaf yet? If not, stick the sub in the passanger seat facing you. HAHAAH :D

Can't bridge a monoblock. It is only one channel of output from the amplifier.

What you have is paralleled outputs. The two positives are actually joined together inside the amp. They are the same connection, just two terminals. The negativves are the same.

If you were to connect up another exact sub on the other terminal, you would actually be running your amp at 2 ohms (assuming each sub has a single voice coil at 4 ohms).

This will actually make the amp produce more power (4 ohms resistance, but double the paths it can take which means double the current can flow, means that the impedence is in fact two ohms), but it the extra power comes at the price of the amp being less able to control the cones of your sub, which means you can lose sound quality. Usually it is described as being 'looser, less defined, not as punchy or clean"

That said, most monoblock go very well at 2 ohm loads unless you are a freak like s_tim_ulate who regard sound quality much higher than maximum loudness.

I'm running 2x 12" SVC 4 ohm subs as a 2 ohm load to my JL 500.1 monoblock and it still goes very hard.

Edit: how's your spider bite?

The sound is great, mate...thanks a lot!
I am fine with leaving it, but I still want to understand the principle....

u may not be able to bridge it but u shoul dbe able to wire the sub in a low ohmage which will give you more power

thus better control over the sub

more details on sub and amp would help

@ monsta - Thank you! That made sense to me,

Question answered...Thanks everyone! May the NOS be with you.....

wire the sub in a low ohmage which will give you more power thus better control over the sub

Al, you've had a shocker my mate. lower ohms = more power/SPL at expense of control/SQ.

Lower impedence reduces the dampening factor (which is based on, in one part, Impedence) and thus the amp's ability to control the cone.

But I would like to live in your dimension Al... 0.5ohm ohm loads and SPL and SQ for all!

Still love you tho bro :D
(I gave his old monoblock a home)

Yeh as has been covered, soz got ur message Boris, but been busy

It is still a monoblock, but as most subs are dual voice coil 4 outputs on the amp allows you to run the sub in series or parrallel (load it down/up) to get the most power.

Otherwise you'd be unplugging your box unnecessarily.

Peace
