don't put in any caps.  You'll have some issues with power when the subs
are totally cranked, so if you find it is too bad, buy a higher output
alt.

I'd use 1/0 or 2/0 guage power wire from the battery to the amps.  Also
upgrade the electrical wires under the hood, most specifically Alt+ to
battery+, battery- to chassis, and chassis to engine block.  that helps
as well.

well then you'll definitely want to upgrade the alternator to battery
line.  I'd even take it to 1/0 or 2 guage.

Your alternator will do just fine for those two amplifiers, I would stall a
good size cap right before the amplifiers and replace the battery with a dry
cell such as an Optima as they charge faster then acid based batteries and
will take a major load off the alternator. You should also upgrade the
alternator to battery cable, 4 gauge will do just fine since your battery is
in the trunk, anything bigger then that is a waste of cash. You really don't
need to mess around with grounds since you can run them right off the battery,
and you can't get a better ground then that.

Brandon,

Sounds like this will be an extremely loud setup...  Are you planning
on competing?

Couple of questions for you.  Are you going to be putting the subs in a
sealed or ported enclosure?  Are you going to use the dual 4 ohm or
dual 2 ohm subs?  If you're trying to get the most out of your amps,
the dual 2 ohm would be best, as you can wire the coils in series and
then wire the subs in parallel to get a final impedance of 2 ohms.
Perfect for running a pair of 1100D in master/slave mode.  (Which I'd
recommend rather than running a single amp to each sub... gain matching
is a pain the rear when they're not bridged/synced.)

Also, which version of the 1100d are you planning on using?  The 1999
or 2002?

You can run either model in synced bridge mode for 2200 watts into a 2
ohm load, which may be more convenient than running one of them to each
sub.  (Probably easier than having to match the gains on the individual
amps.)

What do you have for components in your vehicle?  With that much power
you're going to need some impressive front stage speakers or all that
bass is going to drown out your mids and highs :)

Another option you may want to look at is the eD 15spv2 in a ported
box.  With 2200 watts you should easily get into the 145dB+ range.  A
lot cheaper than a pair of the L7.  And you could dot it with a
reasonably sized enclosure.

If you're not plan on competing... lol... then 2200 watts for a daily
driver is total overkill!!

I ran a single 12" Brahma in a 1.2ft^3 sealed enclosure @ 1ohm powered
by a (1999) 1100d and it was more than enough.  Got it metered at
137dB, (listening to real music, not a test tone) which is impressive
for a single 12" in a non-ported enclosure designed for *music*.

Be safe!  With that setup you can do some serious damage to the ears...

Later,
