Boat Stereo Install Question

[Joe50302]

A friend of mine is installing a stereo in his boat and was wondering what would be the best way to wire his speakers up. I have listed his components below.

Radio: JBL PRV-175

Speakers: 4 X JL Audio MX770-CCX-SG-WH

Subwoofer: 1 X Bazooka MBT8014

Amp: JL Audio M700/5

The amplifier @ 12.5 volts puts out:

Main Channels

60 watts RMS X 4 @ 4ohms

90 watts RMS X 4 @ 2ohms

180 watts RMS X 2 @ 4ohms

Sub Channel

180 watts RMS X 1 @ 4 ohms

240 watts RMS X 1 @ 3 ohms

300 watts RMS X 1 @ 2ohms

Obviously the subwoofer would just get wired up directly to the amp and see 180 watts RMS because it is a single voice coil 4ohm sub.

His question is, what would be the best way to wire up his 4 coaxial speakers to achieve the loudest sound? They are 4ohm single voice coil speakers that handle 70 watts RMS/225 watts Peak.

Any suggestions are appreciated.

Just wire them up to each individual channel. Keep it simple.

Too bad you don't have a dual 4 sub..or run 2.

That's pretty much the same thing I suggested too, the727kid.

pickup1, he is considering purchasing a second sub.

Thanks for the responses.
