I've been messing with some speakers for my car the past few days. I gave a pair of 10inch Sony Xplod's a run tonight. They didn't sound good to me at all. What I would like to know is what are you using, and if you have any of the following; Rockford Frostgate, Kenwood dB+ or Kicker subs. What are your experiances with them, and what do you know about a ported box system. I've come to the decision that ported sounds much better(deeper bass, lower frequecys) than sealed box solutions. Anyhow any imput on the situation would be nice.
BTW, I was driving the Xplods with a 600W amp, 300W per channel and it just wasn't putting out enough bump or deep bass for my pleasure:)

Pwoh
not a half bad system you got there man
I dont own a car and dont have money so i cant help you but just wanted to say nice shiat you got there

JL audio and Punch is all Ive ever used. the JL sound better than anything Ive been around.. Well worth the extra $$$ IMO.

I used to have Rockford Fosgate, wouldn't choose anything else.

Yes they are expensive but you get what you pay for.

I'm really considering a Rockford Fosgate 15" woofer. Everyone tells me 15"'s are terrible, but I just don't see it that way. I think if I feed it enough juice it would sound just fine.

the 15's will probably get u the bass u are looking for, but i say go for a pair of 12's, have two mates, one with 1 15, one with 2 12's... the 15 goes really low, but the 2 12's just sound incredible, turn it up and i cant even stay in the car.

I would try 12"'s but no one here has the kind of power to push them. Well to push them to the point that I would like to hear, the biggest thing i've seen in the parking lot is a 300W amp driving 2 12's. It wasn't very loud and they were in a sealed box which didn't help the low tones. I definatly want to go ported.

well, of course, if you're running two 12's off just one 300W then u wont be able to get crap out of it.... an amp for each sub thats what my mate has... its shockingly loud... well, to me anyway...
then u mite want to consider another amp to run your other speakers off as well.

I don't run the 12's off of a 300w amp, one of my friends does. I don't have anything in the trunk right now. After the Xplod woofer incident, which is weird because my 5 1/4 xplods sound allright in the rear, I don't want to spend any money right now untill I get a good idea of what is out there and what sounds really damn good.

I had a JBL QT600 (600W @2ohms)running 2 JL Audio 12s in a sealed box. Not great for super low bass but the sound is tight and more realistic. Just my 2 cents

oh sorry, what i meant was your friend is running it off one amp...

yeha, I really am looking for the ultra low frequency sounds that a ported system can produce. I've heard several sealed boxes and finding a really good sealed box seems to be a big problem, thats another reason I am going towards a ported system.

Go with the 2 12s. The way you won't be losing the mid-bass. and 2-12s, in the right cabinet, will go deeper and louder than one 15 alone. It's all mainly a matter of the size of the cabinet anyway. I'm surprised that you couldn't get acceptable volume out of 2-12s with a 300watt amp. I have a 60w/ch amp driving 1-15, 1-12, 2-5s, 1 mid horn and 2 super-tweeters per side. I guarantee that at 50%, they're louder than anything you have heard. A car interior should be a lot more efficient.

I have and always will swear by Kicker 10" or 12" subs in a bypass or enclosed box.

One cold winter morning here in NY, on my way to High School, I "shattered" my rear window of my car because of the bass.
