Would a single 15" sp4 get me to where I want to be?

[Beans]

With my trunk so sealed in my crown vic its hard to get good bass all the way up front. I'm

thinking about pulling the trigger on a single 15" sp4.

My hdc sounds ok but I need more output.

Would this be a good direction to go? How is fi's customer service?

So what do you want.

Something that hits lower and plays at higher volumes, sounds decent.

Your trunk is ur biggest stuggle right now. yes the sp4 will get louder and lower but u need more to make that happen and even if both of those happen, the trunk is still a big problem

Something that would probably be the biggest improvement you could do is run your port thru your rear deck but that's not an easy task

A new sub isn't going to be the answer for you. The SP4 has little to offer over the HDC you own apart from 50% more power handling. Ideally you dump 600$ into the sub and another 600$ into a bigger amp and you've gained 1.5db (one more click on your volume knob). Expect a very low return on your investment there.

Thanks for the feedback.

Yeah, crown vic trunks ****, even with the rear seats removed. I have this massive trunk but this tiny area for bass to feed thru, plus its half plugged

up by my full size spare.

50% more power handling plus being a 15 over a 12, that should help some I would think......I dunno, just running idea's through my head.

You'll need a bigger amp. Shaun ran his SP4 on a 20.1, and is now trading me for my DD 9515. A 4" coil can handle more power than a 3" coil, but you don't need more power handling with that amp. If anything, cone area is the only reason you may gain anything. Wouldn't be much though.
