View Full Version : Coax and comp ++ recommendations, JL 300/4

04-30-2008, 08:00 PM
I want to run a JL 300/4 amp in an 07 Honda Odyssey.
I would like to run comps up front and based on the mounting
locations, coax's in the rear. The rear will take a total of 4
6.5 coax's. A set for the second row and a set for the 3rd row.
With kids back there and the way the locations look, mounting
tweeters is out of the question. Don't worry, volumes will be
kept low with the crumb when the crumb crunchers back there.

I want to run the 4 rear coax's crossed over at 80 or 100Hz and
in parallel off the the 300/4. That should present the JL a 2 ohm
load on channels 3 and 4. Also that meas the coax's will split
the 75 watts per channel, for 37.5 Watts or so each.

I'm trying to go cheap, but decent. I need to consider the relativily
low power I am dealing with.

I'm looking at the following coax's (2 sets of each):

Boston Acoustics S65
35 wrms


PG RSD coax
60 wrms (but could do more)


I am leaning towards the BA coax's. I think they will sound
better on 37 watts.

But here's the thing, I'm looking at the RSD comps for the
front. It may be that I am not running enough power for
RSD comps, but I like the price and have heard good things.
Maybe the overall sound would be better off if I choose
the RSD coax's in back. I'm also open to spending a maybe
another $100 total on the comps and coax's together.
($310 instaed of $210).

Here are the RSD comps
120 wrms no problem, but I'll only have 75, how bad does that ****?


I'm open to all suggestion in these price ranges.
I'd like to run the 500/1 as well to a single sealed
12w6 in the back. I want to stick with the 300/4 and
500/1 because other than big 3 I do not plan on any
other real power upgrades. Also those amps are small
and should not get to hot. Also, I can get these amps
used off the forum for $250 each all day long. I was
considering the MB Quart 15 sealed at 1.5 cubes as
well. I am very open to sealed single sub suggestions
within the 500W 1.5 to 4 Ohm power consideration.
12w6 is expensive. The ED's are on sale, but are they
good??? Under 2 cubes sealed is what I have in mind.


Thanks to anyone who replies!

Why would you cross the coax @ 80 or 100Hz? It's a coax, let it take care of itself. BA is known to take alot power, but on the other hand, PG is known for that too.

You could just bridge the amp for the front and leave the rears off deck power.

I guess that could work. I could even get a 300/2 instead of a 300/4, it might
even be cheaper.

Hey, fyi, Im selling a set of alpine type r 6x9's for 65 shipped.. they are top notch sound speakers

I don't think 6x9's will fit. Anyway mids and highs are the one place
I fear going used:laugh:
