Help with a system on 03 Corolla

Help with a system on 03 Corolla

I have a system (1000W or so). It sounds great inside the car, It shakes pretty nice, but there's a lot of vibration. My friend has 2 12"s (1600W) in his Lumina, and doesn't get the vibrations i get. From outside it just sounds like crap cuz my spoiler (i think) is vibrating, and the whole trunk top. Also there's something else more inside the car (back speakers?) that shake and make some songs sound absolutely horrible. Just wondering if you guys out there with systems noticed any problems with this. I was thinking of upgrading too but I don't wanna have it sound worse. Any info is greatly appreciated.

There are a couple of plastic pieces in my ride that shake. In the back of 2003 corolla check for the little flip up pieces.

For the trunk buy some dynamat or whatever to reduce rattling. That is really the only advice to give.

Those are some big systems? I mean I have 2 12" JL Audio W0's and I only run about 150watts to each of them?

Thats a 300 watt system but actually bumps pretty hard? My friend on the other hand has a like a 800 watt amp hooked up to some MTX subs and it hits maybe just a little harder then mine?

Anyone know why that is?

your rear speakers sound like shit for one, or both reasons listed below.

1. they're being thrown by the sub.
2. you're putting too much bass into your in-car speakers..

solutions.
dynamat.
raise the gain on the sub, lower the bass on your stereo.
buy an amp to power your speakers inside the car. this will allow you to adjust each speaker system seperately..

oh, and ported hitting harder than sealed? ooookkkk..

There are several reasons I can think of off hand:

1. A ported box will hit harder than a sealed box.
2. Higher power rating = harder hitting. You say his hits harder. 800W > 300W
3. The RMS rating of both the amp and the sub have a lot to do with it. When you say you have a 300W setup you are referring to a max power setting. RMS is basically the average wattage applied to your subs by your amps. So if his amp has a higher RMS that means his subs will sound louder on average. Also, if your subs RMS rating is significantly greater than your amp's RMS then your sub will be a little thirsty for more power. Typically, the higher the power rating the higher the RMS rating will be.
4. Different cars have different accoustics. I have a 12" sub in sealed box that sounded great in my last car (a Saturn) but sounds horrible in my new Corolla. The sound is all washed out and not clean at all. It's just the way the cars were made different that has that effect (I know this because I used all the exact same components).

There are a million more reasons why your system is almost as good as his. IE subs are in parallel vs series, the guage of your main power wire, your head unit preamp voltage output, equalizer settings, etc. If your setup sounds almost as good as his and you are using 500W less then I would call that a good setup and be happy.

Thanks guys for your help. I will take that all into account

Ported does hit harder than sealed....lol.

All the ported boxes I have seen and heard have hit way harden then a seal'd box.

It all depends on airspace and the amount of room in the car for bass to reflect.

I was assuming that was a given. But that's the gist of it.

you could also just get a crossover to separate the highs, mids, and lows.

A ported box will 'sound' like it is hitting harder, but if you run the right power to the sealed it will distort way later then then ported, thus causing the sealed to hit harder. Bottom line, everyone here is right, sort of...

where in albq are you from? i used to live there.

Someone that knows what hes talking about!
