The Equipment We Chose for Our Project Car
Main Channels - JL Audio 300/2 (MSRP $479.95 USA) and 450/4 (MSRP $799.95 USA)
JL's amplifiers are unique in that they
the same power regardless of power supply voltage (12 v with engine
on, 14v with engine off). This means that your
system will have a consistent sound regardless of whether the engine
on or off. These Class A/B amplifiers produce 150 watts per
channel, and they often bench at 170+watts per channel.
They are also clean. They have been
benched by other publications and performed VERY well. They have a frequency
response of +0 dB and -0.1dB, with a THD of 0.007%. The amplifier also
offers a very high signal to noise ratio of 120 dB on the bench.
Sub Channel - JL Audio 1000/1 (MSRP $1,099.95 USA)
There a quite a few car audio amplifiers on the market
specifically tailored to subwoofers. There has been a big push
towards higher and higher efficiencies. The 1000/1 boasts decent
efficiency, and it has a very good sound quality. There is
nothing wrong about bragging about efficiency, but don't forget
about the overall sound while doing it. JL remembered this, and
delivered with the 1000/1.
This class D amplifier can maintain a 108 dB
S/N, and 0.17% THD at full output (1,000 watts). Most class D
amplifiers on the market have almost double that THD at full output.
Front Left / Right - DynAudio System 360 (MSRP $1,099 USA)
I had a chance to listen to the DynAudio 360 components at CES, and instantly
fell in love with these speakers. They are very natural, very smooth, and very detailed. I simply can't
wait to get these installed. The 360 component set includes a 7"
bass, 5" mid, and tweeter. The system comes with a matched
These will be the main drivers for the
system. Each component set will be installed in a door, with the mid
and tweeter aimed for the best imaging.
Center, Surrounds - DynAudio System 220 MKII (MSRP $599 USA)
It's important to timbre match the main
speakers, so a similar set came to mind. The 220 MKII offers a 5"
mid and tweeter, and comes with a matched crossover. This will be
perfect, as it will fit in the existing rear locations without to
Subwoofer - JL Audio 12W7 (MSRP $749.95 USA)
This is the bad boy of the group. I had a chance to
listen and hold a 12W7 at CES. JL has broke ground by offering a
subwoofer driver that can play loud, but sound extremely good as well.
The W7 line offers a unique surround (the
rubber ring at the outer edge of the cone) that
maximizes cone area. In these modern day high output drivers, the
surround takes up 2" of a 10" driver! JL moved the surround all the
way to the edge, gaining back most of that lost cone area.
The motor structure is built to handle
1,000 watts of clean amplifier power input. When I say built, I mean built. This is a

Selecting components for that dream audio system is a lot of work, but
well worth it. The next article will deal with installing all these neat
goodies, problems we ran into, and how we solved them.
