Will a sound system effect acceleration?

[CrunkRuffRyderz]

I have 2 rockford t1 subs and my whole trunk has dynamat, will that effect my acceleration a lot?

I don't think it'd affect it a great deal, but it will affect it, due to the weight

100lbs is roughly equal to 1/10th of a second

I was gonna say that...Sport Compact Car did an article with a Nissan Sentra SE-R several years back. They stripped it down hardcore to show the 1/4 mile time improvement seen with weight reduction. That's about what it came down to. I noticed a big difference in acceleration when I put a system in my car, it was definately slower.

Let's see...
2 12's t1= about 40 lbs
dynamat=about 5lbs
amp=around 15lbs
box= about 50lbs
around 100lbs of audio equipment will definitely slow you down,but not a lot.

I wouldn't think that 1/10th of a second estimate could be generalized to all cars, SE-R's aren't 4th gen accords...difference in power. I would assume that the greater your engine hp is, the less it will be effected by 100 pounds.


either way in your accord yes it will effect your acceleration, but not by TOO much...buy it will yes.

Well, of course the more power you have the less it's going to affect it. However, it's a pretty good estimate for most cars. It's pretty close for the first 500 ponies or so. I get people asking me why I don't pull all my ICE to make the car faster and I tell them the .1 second it would give me isn't worth not having my bumps when I want them.

i can feel the difference when i have my subs in my trunk or not...abt 75lbs.... not much but enough to notice a slight difference.. like driving all day with some one with you then they get out and u can feel the difference

[Brandoncb7]

I took all of my stuff out of the trunk in my celica before but we doing nothing but racing that weekend. I also had probably close to, if not more than, 200lbs in it though.

Just think of it as your car being stock with a small passenger. yeah somewhat slower but im sure the sound system is worth the sacrifice.

You beat me to the punch. Lol. One sure way to offset the weight is to upgrade the performance parts.

[willsocal83]

yeah it will affect acceleration, but not to bad..

[steelbluesleepR]

any mass will affect your accelleration, it is a simple fact of physics. how much it will affect it is the amount of mass you will be adding. if you go crazy and put an alpine-show-car level of fiberglass and product in the car, yes it will be much slower, otherwise it will be barely noticeable.

Make sure you secure everything properly too. Any objects that are free to slide around will hurt your acceleration even more from a stop. Momentum sucks.

Also from a safety standpoint if you get into a wreck everything in the back will be slung up front and guess who sits up there.....YOU! Of course if you don't have your backseat folded down it may not matter much but it's just something to think about. My dad's known a couple of people that had this happen to them. One had I think a car battery and the other was a traction bar but stereo equipment will fly forward the same way and still not be too friendly to you.
