Have a IA Flatlyne...need a recommendation!

[OmegaBunny 10+ year member]

Ok I finally got everything taken car of with the flatlyne and I figured out the problem....I think. My last four cars that I had subs in were hatchbacks or suvs and there was no back seat or trunk to worry about. I think this is why the output doesn't seem as loud. Am I correct in thinking this? Does the back seat affects the loudness that much?

Now, don't get me wrong, the Flatlyne is an amazing sub. Hits the lows while playing clean but it is just not quite loud enough SPL wise for me. I have an ap15001d that does 950 @ 2 ohm or 1500 @ 1 ohm. The Flatlyne is d4 wired to 2 ohm so my question is, should I pick up another 12" flatlyne and give them 1500 @ 1ohm or go with a different sub maybe one 12 or one 15 that can handle 1500w? I need to be able to feel my music but still want some sq. Budget is $300 or less. Preferably less since I just dropped 300+ for the flatlyne and I am broke at the moment.

Having a trunk will make it a lot harder to get good bass. I played a single 12 in my hatch back and then played it in my pontiac, just about halfed the output, plus you have more rattle and all that goodness

I did have problems getting everything adjusted. Originally had like what would be like 4000w going to it and was like WTF massive clipping but the amp did fine and the sub sounded great //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Didn't really have 4000w but the DMM was reading 90v instead of 43 like it was set to. I adjusted and readjusted and got everything set and was like wheres the bass? Then I realized it was probably my seat so now I need to do something to get it back. I guess I can lay my back seat down but I would really just like to either go bigger or add another.

The extra power on a single sub is basically a waste. Doubling power is good for 3db's if we dont' have any power compression. Even a 4inch coiled sub will have some power compression by 1000 watts, probably at least .5db. On just a 3inch coil, your really only going be like a decibel louder by going with sub on more power, all other things equal. Plus if you use a "louder" sub all your really doing is trading bandwidth for effeciency, it'll be louder, but sound peaky. If you want to keep the sound, but have more of it add the second sub,double up on the power and box space, really the only good way to go.

Those flatlyne's are the best sq sub you can get in my opinion. I would get a second if you can. Ditching them for anything else in the name of sq is stupid in my opinion......

Yeah I decided I might try to get another or sell the 12 and get a 15". Do you think it would be better to get get a second 12" or pick up one 15? Either way I would be using about the same amount of space.

2 12's is a little more cone area than 1 12 and probably fits in the trunk easier, idk how well 15inches high works in your trunk, some cars that's a squeeze. If you have the money I'd get a second 12.

I can go about 18 in total box height so I would have plenty of room for a new build if I wanted but I think I may go with a second 12. It'll just be a while before I can get it. The wifes keeps talking some nonsense about paying bills or something. I just tune her out. Maybe I can find something aroun d the house to sell. Anyone need a couple dogs or cats? I have plenty and will let them go cheap!

If buying a second one isn't a problem financially, two 12's beats out a single 15, generally speaking.

 

[OmegaBunny 10+ year member]

Yeah I'm gonna wait and get a second 12". That'll work out beter in the long run I think

 

[Annnarbor84 5,000+ posts]

I would go for the two 12"s assuming money permits. You should notice a change once you get the other one in!

Bumping and old topic FTW! Found this while searching.

Well my solution was to forget adding a second sub and buy a new car altogether. I figured I wouldn't be happy with the sub situation in my Jetta so I traded it in on my FJ Cruiser! Kind of like shooting out a window to get rid of a fly, but i'm happy with my choice!

OP, what size box is your flatlyne in? Also, are you running sealed or ported. I am looking at flatlyne, but not running into people that are actually using them.

The FJ is a nice truck, just needs some attention to sound deadening. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

FJ's are surprisingly off-road capable.
