Need Help with a 2 Channel Amp

[migueldeluna 10+ year member]

Well I have a 2 Channel 4000 Watts High Power MOSFET VIBE286 amp. Like so..

And I have 2 12" TS-W1207D2/D4 Subs...

Like so..

And I was wondering what would be the correct way to connect them without frying the coil on one of these like i did last time...

heh yeah im somewhat of a noob... and I just wanted to know if it's possible to connect these.

The Amp does 4000w MAX and

2x 300w at 4 ohms

2x 450w at 2 ohms

2x 2000w at MAX 4 ohms

1x 4000w at 4 ohms BRIDGED

The Subs are 1200w MAX

and do 400w RMS

bridge the amp - do this

Start with the gain at MIN. You can always increase it if you believe you need to.

That amp is capable of around 900w and using too much gain COULD cause problems for those subs.

Thanks alot...

ummm do I have to keep it a MIN?

How much do you think I could increase it to where it can be safe, but loud?

I mean would it be ok if its atleast at 75%?

you will be fine, that amp wont put out close to 4000 watts, so you will pretty much be fine wherever you set it

Wrong....

Thats why I fried a coil in one of the subs a week ago..

This amp does 2000 watts rms...

The Subs do 400 rms each...

so yeah it has to be a specific set up..

luckily i already got it.

what are you fuses rated at on your amp?

 

[blackbonnie 5,000+ posts]

waiting on your fuse size and how many, i will prove to you that, it wont run even near what you think it will

fuze size? idk the small ones? they were 35's...

one of em broke so i got 40's

It's a 900w rms amp -- the 2 x 450 at 2 ohms equates to 900x1 bridged.

A 900w amp with the gains set too high could produce enough excess power (clipping) to be a problem for those subs.

Miguel - read the gain setting tutorial. It's NOT difficult to do it right.

okay so if you take your fuses (two 35 amp fuses) and add them together (70) and then multiply that by how many volts you will give you amp (we will say 14) you get (980) watts out of that amp. provided you give it full power, you are not gonna get even close to what you think it does, not to be a dick, but you get what you pay for and im tryin to help you understand

Just trying to get the most of it..

umm do you think that if i change my fuses from 35 to 40 that it'll affect it in a bad way? the amp.

and i think i got off pretty cheap too..

the subs and the amp were 220... overrall...

It won't help.

Basically you reduced over-current protection by about 14%. If you run the amp near its limits a lot of the time it COULD lead to a problem. If not, it won't make much difference.

you should always keep the recommended fuses in there. reason being is that they are there to protect all your internal parts. with 35 amp fuses they will blow when they should, with 40 it will take more current to blow them and more current will get through and could potentially damage your amplifier. so if i were you i would go back to 35
