AMP/Speaker wiring in cooler boom box

[Chupacabra111]

My first box was great. I am making another one because I wanted a subwoofer. I am not an expert at AMP and Speaker wiring so I need help if you are able.

Equipment:

Bazooka BT6028DVC 6½” tube:
· dual 8-ohm voice coils
· 5-way binding post wire terminals
· power handling: 12-300 watts RMS (150 watts per voice coil)
· frequency response: 39-1,500 Hz
· sensitivity: 100 dB


Rockford Fosgate FRP400-4 Punch 400:
· 4-channel car amplifier
· 50 watts RMS x 4 at 4 ohms (100 watts RMS x 4 at 2 ohms)
· 200 watts RMS x 2 bridged output at 4 ohms (4-ohm stable in bridged mode)
· CEA-2006 compliant
· Dynamic Thermal Management cooling system
· variable high- and low-pass filters (50-500 Hz, 12 dB/octave)
· variable bass/treble boost (0-18 dB at 45 Hz, 0-12 dB at 12,000 Hz)
· optional wired remote bass/treble boost
· Class-AB amplifier design
· MOSFET power and output stages
· 4-gauge power and ground leads and an 80-amp fuse recommended — wiring and hardware not included with amplifier

I have a Pioneer head unit with 2 channel output, so I'll be using the amp in 2 channel mode.

I haven't purchased speakers yet. I'd like a recommendation with cost in mind (I have already spent too much on this...)

My guess is to put the amp on low pass for the tube, and high pass for the other (I want 4) speakers. What is the best way to go about this?

you can just connect both pairs of speakers to the front channels and bridge the rear channels and a put a sub on it. There should be a diagram in the maqnual for this setup.

I was very much hoping for an easy answer like that. Thanks! Any recommendation on what size speakers to get? Watts? Also, should I run the 4 speakers serial or parallel?

[PaulD]

run them parallel, if you run them series each speaker won't be getting much power.. Any set of 6 1/2 or 6X9 should do, power wise. Just remember you will not be able to fade the volume front/rear with this arrangement.

Thanks!

OK, ran into something else: The tube is dual coil. Should I wire it to 2 of the 4 channels, one on each coil, or should I wire them in parallel to a bridged 3 and 4?

(Keeping in mind the specs say it's dual 8ohm voice coils)

Then, I'll have the 4 other speakers on the first 2 channels at high pass. In parallel as you said earlier. Looking at the power of the amp, what is recommended for speakers watt and ohm wise?

[PaulD]

you just have one tube with one sub in it ? If so, wire the 2 voice coils in parallel and then bridge channel 3 & 4 on the amp to run it
