Looking to buy 15" sub and would like some advice or suggestions

[Jhensley209]

I'm going to buy one 15 and I'm looking to spend 500 to 600. I was thinking about getting an fi sp4 but are there any other subs in that price range that would be a better deal? It's going in the trunk of a small 4 door car

Do you know what amp you are going to run?

I have an audiopipe 1800 right now and was planning on getting one more

I have heard of people putting crazy power through a Soundqubed HDC415 but I don't know if it is in the same category as the fi. Maybe someone with more experience will chime in.

I actually had a co-worker just buy a HDC415 and put it in a Dodge Stratus paired with two SoundQubed 2200.2's.

Tons of great subwoofers in that range, the Fi SP4 is an excellent choice.

Here are a few others: DC Audio XL 15, Ascendant Audio Mayhem 15, Incriminator Audio Death Penalty 15, and SSA Evil 15.

I wouldn't suggest strapping amps, i'd actually suggest selling your Audiopipe and going with something like this:

It's just easier to run one amp than two... Also, looking into this range, do you have a decent enough electrical system to handle that kind of power or are you still running a stock alternator?

[Jhensley209]

I was actually looking at the hdc415 also and it looks like a good sub that can handle some power. As far as the amps I have ran strapped before and didn't have any problems with it. I am running stock still in this car but will be upgrading as soon as I have everything I need.

Personally, i'd rather run a HDC415 on something like a SoundMagus VS3500 at .5OHM since they can crank out just under 4K set-up like that. But you will need a high output alternator and a large second, possibly third battery.

As things are right now, my system is louder than my co-workers system that has the two strapped SoundQubed 2200.2's and he also has more battery reserve and a higher output alternator than me. We've checked his wiring and set-up about 5 times now and we can't figure out why... Other than the amps are probably not doing anywhere near rated.
