What watts is your amp? And how is it wired in?

**323madness** · 17-05-2009, 07:33 PM

the amp is 1200 watts and the subs are bridged some door speakers and your set

also running 2 12 audiobahn eternals with the new alpinev 1000

Do you know the RMS watts of your amp.
When buying a Power Cap you need 1 Farad per 1000 Watts of RMS power. Find out your RMS output and that will tell you how many Farads you need.

**323madness** · 17-05-2009, 08:05 PM

350 Watt RMS @ 4 Ohm
700 Watt RMS @ 2 Ohm
1000 Watt RMS @ 1 Ohm

Is this at 1kHz or across the audio spectrum. Continuous or peak?

**323madness** · 17-05-2009, 08:42 PM

as far as i know its continuous at the moment iv got it on the 12" jls and its giving them a good run for their money

You'd be better getting a 3 or higher Farad Cap. Then you have scope to expand.

**323madness** · 17-05-2009, 11:00 PM

thanks mate ill get one and see if it sorts it out. also would i be better off running 3 10" or 2 12"? would i need a backup battery?

**turbonutter69** · 17-05-2009, 11:06 PM

If I was you I'd run two 12's. With a big enough power cap you shouldn't need an extra battery. How is it all wired up? The quality of the wires used will make a difference also.

Wiring is crucial with bass units. They sink a lot of current. An extra battery will be a good idea but, as Tn69 says, some high current caps will help as well.

Personally, I would do neither with my car but it has a very good factory installation. If it didn't, then I'd be down the same route as you are.

Think of lead acid batteries as latent caps (which they are). they're basically just very high capacity polarised electrolytic capacitors whose charge storage rating could be rated in thousands of farads.

An electrolytic capacitor whose designed purpose in life is to supply extra current to support audio transient peaks has a higher discharge rate than an compound cell lead acid battery. It's internal DC resistance gets lower as it discharges. A lead acid cell's internal DC resistance gets higher as it discharges.

the wiring im using at the moment is jus normal amp wire nothing big. basically the cap gives me the bursts of electric i need when i need it instead of it draining my battery. also what do you think of the audiobahn eternals are they any good?

**turbonutter69** · 17-05-2009, 11:48 PM

I'd upgrade the wires to 2awg or 0awg. honestly the quality of the wire will make a big difference.
As for the Audiobahn's they make very good subs I have two 12 Audiobahn's and I rate them very well.
Just a quick question what do you want out of your install?

**323madness** · 17-05-2009, 11:55 PM

i want my bones to vibrate but with clear cut sound right now its temporary iv got the fat wiring just testing the waters as to whats best to put in it. i rate the audiobahns aswell iv put them back in the scooby the. what headunit should i use?

**turbonutter69** · 17-05-2009, 11:59 PM

Have you got a budget in mind? Alpine to gread head unit's some Sony head unit's are also pretty good. Pioneer also do some good head units.
For raw bass why not have a look at Alpine's competition subs.

**323madness** · 18-05-2009, 12:07 AM

i already purchased the new alpine v 1000 amp. very clear sounds and i also have the 1023 a 923 and 2 723s. i dont have a budget in mind i just want the best sound i can get without being 2 outrageous. ive had a new pioneer with ipod connection they are good but have too many functions for the sounds.and the volume menu button goes funny i prefer alpines older units and sony. what do you power your audiobahns with?

**turbonutter69** · 18-05-2009, 12:13 AM

Mine are powered by a Juice JA1200 Class D amp. It's 1200 Watt unit but it's wired up in 2ohm stable mode so it is actually producing 2400 watts RMS. The speakers are only 600 watts RMS.

I set it up that way to be more efficient as i'm not driving the amp as much as if it was in 4ohm stable mode which is 1200 watts RMS.

**323madness** · 18-05-2009, 12:16 AM

So how would i go about getting deeper low bass?

I think you'll get a better result with a single 12" bass driver for the low end. It's important to remove low end signals (say under 100Hz) from the other drive units in your car. If you send all the signal to every speaker you will get phasing problems. It's where certain frequencies are reinforced and others damped.

would i be better with 2 amps on 2 subs? im gonna be using a separate amp for al my components. thanks for your help so far hdi and tn69

You can have one amp for both subs. Just make sure they are dual voice coil and you'll be able to wire them in series or parralel whichever you fancy.
