woofer

[Chippie]

I’m considering fitting a pair of the hifi woofers behind the seats in my e89, I’ve already upgraded the 4mid range speakers and fitted a couple of tweeters powered by a vibe 65.4 mini amp and coded the head unit to hifi, would another 65.4 amp be enough to power the 2 rear woofers using 1 channel to each 2 ohm rated woofer at 4 ohm 65w, leaving 2 channels free in case I wanted to add the middle mid range and tweeter later, or would I be better using the vibe powerbox 400.1m using the mono channel and should the woofers be wired in series or parallel?
I’m not wanting to spend a fortune, just after a bit more from the system.

Thank you for any advice. Sound systems really aren’t my thing

Here’s the woofer I installed in a previous Zed. :rofl:

Are you talking about woofers or sub woofers?..very different animals…

For clarity, this is from the manual for the Vibe 65.4 amp. Points to note are numbers 2 and 5, and the last sentence of each description
Personally, the way I see it would be to use the Front Low Level outputs from the 65.4 (number 5) and into the inputs for the 400.1M, and then feed the two subwoofers in parallel. But I'm no expert with aftermarket audio, I'm sure we have some experts who are though :wink:

And if anyone wants to take a look, here are the manuals for both amps...

If they are sub woofers we need to know their impedance first before being able to offer the ‘best’ wiring / configuration option..

The factory ones

Thanks for the replies, they are the factory ones, I’ve seen a couple for sale and thought it may be an easier option, the stickers on them say 2 ohms, they are from 2 different cars with different part numbers, one’s a 201o and the other a 2015, although I can’t see that making any difference.
I did think the 400.1 would be the better option.

What are the two part numbers?

 

[B21]

Well at 2 ohms you can wire them in parallel to give a 1 ohm load..unusually this amp can drive a 1 ohm load so according to the spec sheet it will deliver 400 watts rms into said load..the danger is that you can very very easily overdrive and destroy the subs with that power rating..

The other option is in series giving a 4 ohm load which gives 170 watts RMS..I think its prudent to go that route..IMHO

They're not great quality speakers..I have lots of spares if you need some!

When I’ve checked again there’s 2 the same available and they are 2009.

Thanks Peter, as I said I’m not after a top notch system just something better than the basic one.
I’ve made an offer on the 2 so will see if it’s accepted first.

Yup a lot better thaan the 6 speaker system for sure..anyway in series is the way to go!

If you are interested I have a couple of factory subs with their enclosures which I could let you have for a very reasonable price.

Chippie is still in the market..I have some 677 subs but not the enclosures..

Thanks for offer but I’ve just bought a couple.

So, I’ve been contemplating the best way to wire things up and think I’m leaning towards this.
I’ve got a Vibe 45.4 already fitted under the dash so I was thinking of using that to power the door mid range and tweeter from 1 channel left and one right through the original wiring harness, then adapt the Vibe harness to power the other 2 channels to run the 2 front footwell woofers wired separately to the car harness.
Then run the rear 2 channels from the head unit to another Vibe 45.4 amp in the boot mounted where the 676/7 amp would be and use 2 of the channels to run the rear mid range speakers wired straight from the amp, then use the low level output to feed a Vibe 400.1m for the rear 676 subs running in series using the remote wire from the rear 45.4 to wake the 400.1m.
I can easily pick up the power and earth from the battery.
This would also leave 2 channels free for if I decided to add a couple more mid range rears.
Can anyone see a problem with doing this?
Thanks for any suggestions / advice.

That will work..do the amps have tone/level controls?

The 65.4
have crossover mode select switch
This control is used to select the crossover mode of the rear channels of the amplifier.
FULL is for full range output, HPF is used to limit the amount of low frequency information
passed to the speakers and is fixed at 80Hz.
The 400.1m
Bass boost control
This control is used to add bass boost to the amplifier centred at 45Hz and is adjustable
between 0 and +12dB

Low Pass Filter (LPF)
This control is used to set the crossover frequency for the amplifier when LPF is
selected. The frequency is adjustable between 30Hz and 150Hz
The tweeters have built in crossovers
Any tone and bass adjustments would be from the head unit
The only other option would be fitting pass through filters
