My sub woofer weights excess of 40 kgs with the enclosure it would be in tune of 60-65 kgs...Have not weighted the amp since I do not have that big of a amp to drive the beast. But very soon when I have the money to buy another one of the sub and the amp for both of them.


@Mods I am have no intention of doing marketing here just sharing some facts, If there is any issues the post can be deleted


I did not understand the 135 db thing. Even two pioneers can hit 135 db easily.

what all amp are you planning to buy to feed this sub you atleast need 5000wrms (pure) as hooles can hadle 7000wrms,you must have shortlisted some amp so wanted to know.

you are spending 5L to acheive 135db,any pioneer,jbl,... brands can easily do 135db .

lets be open to discussion and not have a comeback to everything that is said!
with your ICE.
Hey Frank,

Agreed! This is not the place for a slugfest. Coming to suggestions, I need to know how to balance the whole deadweight in the boot and if anyone's installed over 100 kgs with stock suspension. Will it hold good? And I'm really concerned about the rear windshield and if it will be affected adversely due to the excessive vibrations.

Has it affected the handling of your car? and are people able to sit in the back seat without the car bottoming out at the rear?

Guys,

I'm on the verge of chickening out of the Earthquake. Not confident of handling as pointed out by some of you. Not sure about rear seating since I don't want the car to bottom out. Don't want to change the suspension since it's a car I bought recently. Most importantly, it's my wife's car and she's not too excited!!

As Navinji says practically results might be different. He might be able to achieve more than 145 DB too.

Who knew 2 iDv3 can do 151.2 DB. Remember Sam's car ?

yes it will affect the number of passengers you can put in the back seat and the car's handling. only you can judge if that sacrifice is worth it. For example when I was 27 and single it was, when I am 47 with a family it is not.

Wow Navin. You really know how to drive the point home! That was a very simple but extremely valid point.

I guess I'm past the age albeit the fact that I'm only 29, but married.

This is given me a lot to think about.

I haven't installed or even seen a Civic with over 100kgs in the trunk. But I'm sure it's going to cause the car to sink quite a bit. Using a stiffer suspension should solve this.

There won't be as much pressure on the rear windshield as there will be on the walls of the trunk and the trunk lid. Those will surely flex like mad if not reinforced.

But for a SPL car, a sedan is anyway not the best idea, is it?

Debatable! The same equipment couldn't do more than 140 or 144 (i think) in an SUV on the so-called infamous delhi db drag!

@ Mods: I'm NOT starting any issues, but its just that what I've been given to understand over last couple of threads!

Kindly feel free to edit if its not acceptable.

Care to link the thread. We can view it even if it is locked.

And I cannot find the Feb 2005 issue on the site given by you Care to help in that department too.

depends on cabin gain. remember my old posts about the 60-80Hz region being where most cars have problems. guess they still have not sorted out these issues.

Look at the chart again see that boost sub 50Hz. This boost will make the car sound bass heavy and not natural if you stuff a sub that is flat in anechoic conditions in a car. this is why I have hinted in the past that a car actually allows you stuff a sub in a box one size too small (high Q say 0.7<Q<1)and then flatten the Q by increasing box losses (QL) by going aperiodic. The loss in sensitivty due to box losses is made for by cabin gain below 50Hz. Use the cabin gain for your gain. Use the cabin loss for your gain. DIYers have a huge advantage over speaker companies. They can design for their cabin/room!

If i am not mistaken Bhagwan was using custom build enclosure in his Skoda with tiles in it which was around 80KG each.

He might be able to give tips on suspension problems.
