After asking some questions on this forum I installed my amp and sub today. I was trying it with the radio and was initially REALLY dissapointed no matter how I adjusted the amp the sub just sounded like it was making a lot of noise and not much music, but then I burned a cd with some good bass tracks and WHOA it sounds awsome and it doesnt even drown out the stock system. But this sub is a pounder, supposedly you can hit 133-135+ dB with just one of these 12s which I thought would be a lot for a guy who has never owned anything but a stock system, but it doesnt seem that loud. I had it turned up as loud as I've had it and it didnt sound loud but it brough neighbors coming out of their house from all around, and my buddy 2 blocks down the road felt the need to walk down the street to see where the hell the bass was coming from

Too bad my car sounds like a tin can now with all the rattles in the world.

Hey how did you guys secure your amp and sub. I need to tie them down someway so if I get into an accident nothing moves, or doesnt move just doing some high speed corners. I want to mount the amp on the back of the seat.

 

you can get some L brackets and home depot or lowes and secure them down with those. what sub did you get?

 

Which sub and amp did you install?

 

You'll be no where near that 133 db mark with just a standard install. Pre-fab box i'm assuming too?

 

I got a hifonics tx1005d amp with a Fusion Power Factory FPW-1200 12"

Deff need to do some dynamatting with the cheaper stuff to get some of the rattles out

 

Dont use the junk stuff, ive been redoing mine and found a bunch of sounddeader I was able to pull off without much effort. If done right (and with good product) I shouldnt have been able to get it off at all.

Just my .02

 

I still think on a cool day you could pull some SS off. its the asphalt stuff apllied with heat is what sticks like that I think.

 

I would rather have it removable.. All this audio crap is heavy and when I race I want to get as much out of there as quickly as possible.

 

lol dude do not pull sound deadening out...140sqft of SS=less than 70 lbs.

 

If you can pull it off easily, it may not be "deadening". Think before you put that stuff on. It should not be able to come off.

 

anywhere near 70lbs is a STUPID amount of weight for some sound deadening. My SFCs arent even going to be close to that weight.

 

do you know how much 140 sqft is? it covers the entire car. trunk=40sqft which is nothing...lose 10 lbs and it makes up the difference.

 

^^^^ +1

 

I understand 140sq feet is quite a bit but if you think about it it starts to add up. Look at hoe much weight I've added to my car already

RSB 20-25lbs
FSTB 10lbs
SFCs 50lbs
Sub 50lbs
Amp + wiring 5-10lbs
LTB 15lbs
Dynamat 15-60lbs


Thats around 200Lbs of extra weight in the car that wasnt there before... thats no tiny amount.

 

so whats the difference if you are some 150lb kid compared to e55amg2 who weighs about 100 more than that...his maxima would still smoke ya with his rsb and fstb (which I own now). the added weight you put on is for purposeful reasons. make your subwoofer box out of birch to save some weight and that should negate the weight of the sound deadening. adding speaker wires should not count towards to the weight. are you that competitive of a racer? you do realize 100 lbs=roughly .1 off a 1/4mile...get some 16" lightweight rims/tires if you are a racer and concerend with unsprung weight.

 

Blah dont bring him into it, his car is weaksauce.

Especially in the audio dept.

 

I dont know about you, but when I have a 200lb passenger in my car it feels significantly slower than if I'm the only person in the car. I dont care what that relates to in the quarter mile. If I can feel the difference than thats pretty big.

 

Ok, so what exactly are you planning on doing then? Get some more bolt ons to make up the diff. Atleast you have the 3.5 dont complain. You should see how sluggish the 3.0s get with a few extra hundred pounds.

 

+1, all these bishes need to stfu

 

Haha..true..true..

Headers alone should make that extra 200lbs disapear, but I want a mid to low 13 sec I35 so thats hard with this extra weight

 

get a 6 speed swap.

 

6sp swap haha I'de be better off doing a car swap

A built auto would be much better for drag racing anyway but expensive

 

you realize having your gas tank full or almost empty makes a more substantial weight difference than the deadening you plan to do in your car.

 

God yes.. again these things add up. Obviosly I'de already be racing with a quarter tank of gass.. Based on how heavy the stuff is I will probably deaden the trunk because it rattles like crap and I think I am loosing a TON of sound out the back. I think if I deaden it I will get a lot more sound in the cabin and cut down on the rattles, cause right now I just sound like a ricer with a car that rattles louder than it booms.

 

Maybe you should decide what type of car you want to build. A race car, a car for your audio, or whatever else you can think of, and then go that route. You may sacrifice one element to achieve the other. Get over it, that's the way it is.

 

I want a car thats flexible. Like the amp and sub add considerable weight but when I go to race on the weekends I can remove it in about 5 mins. I can take the FSTB and RSB off in less than a half hour.. and I can take out the passenger seat, rear seat spare tire and jack in about another 1/2 hour. In about an hour my street ride is ready to go racing. If I put permenant sound deadening in there, obviously I cant remove it, thats the only real problem with it.

 

seriously! especially with a maxima. these cars suck for SPL and they suck for racing. pick 1 of the 2 and try your best.

 

Alright here is what ive come to terms with. ^^^ Holds more true then anything really.

I just came to terms with things, low to mid 13s is going to sacrifice a few things that I just didnt think were necessary just so I can drive faster.
I dont care who thinks what about this but the car is still a 4dr cruiser period. Sure they got some guts, but not anything that will easiley dip into the 13s.

Losing some reliability is 1 concern, with high performance stuff things will break a lot more often. Its just the way it is, been there done that. I had plans to do the whole turbo thing, tranny swap... then I actually thought about it for a sec. Wth is the point?
If I was to go to that extent, id go with no less then a G35, atleast thats RWD. Stuck to the cruiser thing, car still looks great, went a bit overboard on the sound system & I still dont regret it.

Its just 1 way or another, I look at it as if you want a fast car, start off with 1 then get stupid with it. This however is still a 4dr car, id rather be in comfort then worrying about my axles getting destroyed or my A/F ratio going too far off & detonating the damn motor

Bottom line, PICK ONE. This isnt really the car to try to have both, can it be done? sure. All it takes is money. Just not worth it IMO.

 

Why dont you let me modify my car as I choose because dipping into 13s isnt as hard as you think. With headers, intake, exhaust, decent tires, vb mod, VAFC, a good tune, and a 50 shot and your there pretty easy... so I dont see why its hard, plus my stiffer springs and shocks, used for auto X also have nothing but positive effects on traction at the track. The stiffer springs reduce weight transfer (great for FWD cars) and reduce wheel hop. Plus if my system is removable theres no reason I cant have my system in on the street and out at the track.. I dont see how thats sacrificing anything. Does the car do any single thing great? No but it does them all well, which is the type of car I'm looking for so stop telling me I what I HAVE to do or that I HAVE to choose one or the other because its not true. Based on how you set up the car you control to a degree the flexibility of the car. Look at Matt Blehmco's car. He has an amp and sub in the back but he does plenty well on a road course. If he wanted to he could also go faster at the drag strip but thats obviously not one of his focuses.

To be honest sorry guys but I dont care enough about car audio to add more weight to the car, the only reason I put the sub in my car is because I got it for free, and I paid about 200$ for the whole system. Going fast is much more important to me, even if this is only my daily driver.

 

well nobody is telling you wtf to do but I'm gonna stick up for my boy hitman here. you came along asking to take out sound deadening...that RIGHT THERE is one of the dumbest posts I have ever seen regarding car audio. it makes 0 sense whatsoever to do and I guarantee nobody has ever used sound deadening during the week and taken it out on weekends to shed 20 lbs. do whatever you like, but this forum is here to help not hurt you. Hitmans general statement was: if you want fast go elsewhere because a 4 door nissan with 255 hp stock that is FWD is not meant to be a racer plain and simple. any person on this forum with a half a brain can tell you that. many people get into the 13's but when you look at the general maxima population it equates to about .0005% tops! That is all.

 

I never said I wanted to remove sound deadening. I said I dont want to add weight to my car by adding sound deadening because its not removable. If it was removable I would think about getting it. I think I am still going to do some sound deadening like the small ammount housecor shows on his site to get rid of the rattles in the rear deck and I'm also going to stick something under the license plate to stop it from rattling but nothing like you guys are talkin about.

And your views about the performance of the maxima are yours and yours alone. I dont think you need to speak for other people. I think its stupid when people invest thousands into their car stereo but I'm not here calling you stupid for doing what you like. I am not making my car a race car. I am customizing the car to fit me better. Stock the car handles like crap, its not fast enough, and the sound system was lacking bass. So I am changing those things one at a time. I am building an all out weekend racer on the side as well with a completly gutted interior to really fully satisfy my need for speed, but I dont want my daily driver being slow either and it wouldent be bad if it handled a little better too. The maxima has so much more potential than how it came from the factory its insane, with just new tires and a RSB the car is a completly different animal. I am just fufilling its potential. As I like to say I'm making it the way it should have come from the factory, if Nissan had really wanted to invest the money to make something special of this car.

 

As far as im aware anything I said was in reference to me. Like you said, its your car, do whatever it is you wish. 13s isnt that difficult to break into, all you really need is a pair if slicks & a 50show & your capable of lower 13 very much dependant on track conditions.

Just speaking from personal experience. Performance & the word reliablity rarley go toghether, been there done that. Your either going to get lucky, or just learn the hard way. Just letting you know what to expect down the road. Nothing more.

Have fun with it & good luck.

 

Yeah slick ummmm.. what u said lol..

 

if you want to save weight and still use sound deadining, use edead v3, it is a liquid deadener. do not spray, paint, in coats if you use it.

 

NO, just say no. That is all.

 

Might as well throw some Pyramid and Pyle in your car while your at it. +1 to just say no.
