I am amazed at the fuse use, they have a non-negligable internal resistance (its how they work at the end of the day), they age at every turn on and reply on friction contacts!

I guess the populus are not educated into the benfits of CB's fully yet  

You are right about the fuses deteriorating, but when fuse sales are so lucrative, where would the business sense be in educating people about circuit breakers

Lol, thats typical of me, always looking for the optimal engineering solution!

Does any of you guys know where the best place to route an Amlifier live down the Omega from the Battery?

Will have a look tomorow but just wondering if its an easy job.

many thanks

What current are you likely to need? There's generally a caravan feed in the boot along with the lighting feeds. You just need a fuse in he fuse box to power it up.

NO !  

That s not a suitable feed for an audio amplifier.
A heavy cable MUST be run through the car, connected directly to the battery and fused in the approprate manner.

 

TBH It is not really even that suitable for the caravan - I laid another wire for the fridge

Will be drawing around 70 amps on music!

Will be running a second battery anyway as the Amplifier draws around 70 Amps or so !

dont you worry ile be doing everything properly!

I just want somthing to force the lower end Frequencies flat and right down to around 25hz!

Good to see someone tackling this properly with a second battery. I would suggest to consider a power cap as well, and if you need further advice, do not hesitate to ask.

And why do you even think you need something that big to do that?

I have in the past designed subs that will go down to 20Hz which will shake a house running just 200W......efficiency is king!

Oh dear Marks DTM Calib - Are you really THAT OLD ?

Unless you can burst the welded seams of a car with a stereo, and need to reinforce it with concrete, you are just not trying hard enough.

 

[Marks DTM Calib]

Lol......its terrible really.

Here is me, managing design programmes where efficiency and low power consumption is king.!

Do people forget that its the x10 rule for output!

[Christian]

Efficiency is king but i have a Woofer which has 36mm of excursion and a rather large motor structure so i need a lil bit of D class goodness to give it its Limits!

Althogh in my house i have a ten inch sub in 2cuft tuned to 25hz off 75wrms .....now thats efficency  

Power Caps have never been in my Intrest Tbh , ive never gained anything.

You guys seen my old car didnt you?
2x 18 inch Resonant Engineering Woofers
2x Orion HCCA5000's (2.5k each RMS)
4x Hawker Powersafe Batteries (each batt weighs in at 47 kilo's)
110 Amp Alt.

Gave me 153.3 DB at 25hz!



























Evan tho this was built for competition and more so me having a soft spot for low frequencies.

This box was 22 cuft and tuned to 25hz with 150 inches of port area.

Did me well

This is my scores

Ive had a soft spot for Audio for many years, Loud music in the Astra was a big hobby at them low frequecies but now im consentrating in SQ in the Mig so i had an old 3 cuft box tuned to 27 hz and im going to us it.

Now im mainley ingo home entertainment.

Running Mostley old skool stuff.

Pioneer SA-540 (1980's ) Amplification for my old Goodmans Magnums (before was it akai that took over and they went crap)
Pioneer SA-250 running sub through also a 50 hz x over wound by myself! for the lo end.

My PC room i have Pioneer SA-540 running Mission 700 series Bookshelves.

[Dave DND]

Thats certainly some respectable scores

161dB was our best claim a few years ago -

And as far as SQ goes, unsure how long you`ve been into this, but if you were around in the late 90`s when the first UK car to hit the flat 40 was an Isuzu Trooper that then kicked off the LOUD! Association Sound Off`s around Europe and the long running feature of the Street Bass Challenge on C4 Big Breakfast for a quite a few months -

Well that was us behind it !!

Oh, and next time you see the Iceman,

say hi from Dave Watts & Sid Jervis


 

[Christian]

Yea i seen it on Big breakfst.

You will know some of my old skool pals

You proberbly know yourself, the old Audio control mic was quite a far bit out compared to the Term Lab.

My system hits 156.2 on the audio control.

All the guys back then and still evan now tune there vehicles high for ease of pressure and cabin peak frequecies.

The most popular right now is Fiat Panda's, there cabin peaks at 72 hz so its perfect.

Only problem with hitting big numbers at such lower frequencies is.... Its alot harder because you loose pressure fron door movement and screen flex!

Altough in the end before selling the car i was going to make a 25mm roof.

The Woofers i was using were actually an SQ Driver, tho they had an awsome x max and motor strength and power handeling, but in the Streetbass world they were always pushed to there limits and got thermal very quickly.........the smell of voice coil i here you say lol hell yes they stunk!

You should know Goeff ( aka firestarter) many vehicles
also there was Paul Coughlin ( Aka Mazdawg on the local forums.) he had then a Golf which did 170 db an audio control

Also Ian Iceman Pinder (Cortina)

Ray Harvey( BMW )

Got theres so many and i keep regular contact with them all.

I see  Iceman regular at shows and regular on the Phone TBH  

Sign up on Streetbassers.co.uk and you will see most oldskoll chaps on there still!
