i havent bought it yet.. 7,000 is the price they gave me for the Pioneer TS-WX110A.
What i like about it is that its thin enough to fit under the front seat.
i thought LOC is need if you are retaining the stock head unit.
You're paying too much for space-savings. The rule of building subwoofers is simply easy.. you get three choices: (1) bass extension (2) efficiency (3) space-saving. And you can only get two of those. The more knowledgable ones would feel that it's a waste of cash. If you're going to get a compact underseat sub, you're better off simply running the midbass without a high-pass filter.

I understand that you need space but a 1 cubic feet box isn't huge at all -- it fits quite nicely sa front passenger seat mo while still having sufficient legroom. For 7k, you can easily buy off a 3k subwoofer driver and spend the rest (and have change) for the box. Of course if you're consulting somebody who has stocks of the Pioneer, they'll happily push you for the purchase. A sale's a sale.

A line out converter isn't magic. What it does is convert speaker level output/line-level output/high-level output into low-level signals (RCAs). Why is the signal called high? It's because speaker level connections carry voltage and current. RCAs or low-level signals on the otherhand simply carry voltage which you then send to your amplifier. The amplifier then amplifies the voltage in its pre-amplifier stage (hence the gain knob), adds current in the power-amplifier stage.. and voila... you are now sending speaker-level connections again to your speaker.

An amplifier that accepts speaker-level inputs simply means you're "skipping" a step. They're harder to find as most amplifiers accept only RCAs though.

At the very least, leave the subwoofer out of the equation and throw it in once your system is "finished" and you feel it's inadequate. Getting bass inside a car isn't hard at all.
