If your choices are 4 or 8 ohms total, and you're using a 4 ohm driver, it looks like series wiring is your only option. Unless you have a stereo amp. Then you can run parallel inputs, one channel per driver.

Thanks for the suggestion, I was afraid someone was going to say that. Any other way?
1- What I am using is a JL Audio HD600/4 bridged channel 3&4 that will produce 300 RMS Watts @ 4 or 8 Ohms load.
2- I was trying to avoid individual channel for each driver. I am going to be using this with my boom box built and trying to keep my boom box with minimum connection/plugging.

I advise looking at the youtube section here. I made a posting of someone elses AT in a
blue sedan. One 8" is all it takes! My BAT hasn't seen anywhere near full power.

300w at 8ohm to make crazy stupid loud with dual 8". Mine is 8ohm and stupid loud enough to shake the mirrors with it turned up halfway on 130w amp.

blue sedan didnt sounded loud, compare with what I got in my car. I do want to use 2 - 8" as I will be using this TAT outdoor around a pool area (open field).

And not in a car?

Wrong tool for outdoors. Auto tuba is designed around having boundary gain to get response in the lower reaches. In car it goes gangsbusters. Inside in a corner it's fine, but outdoors not too flash I would think.

Like Greg said, go with the pro subs if it will be used exclusively outdoors. The TAT could manage outdoors but there are much better options (like T39).

Well guys, I do see there is many more options to give me crazy outputs, but I am trying to keep it small and portable as it's to be taken along a boom box that I made. My boom box is pretty loud with lots of vocals but no hit, no bass, no thump, is kinda missing at least a little of bass or hit to sync with my boom box. I will later upload a picture of my boom box.

The autotuba is still a heavy box. I have trouble getting mine in and out of the trunk. Mostly due to the weird angles I have to wiggle and heavy driver but it is still a big heavy box. Have you considered starting over and building 1 or 2 jacklite 10's? Many people on this forum rave about its performance for a portable all in one sound solution.

Thanks for your consideration Corona.
Which one is the smallest of both design Jack 10 vs AutoTuba 8"? I also think and saw that Jack's design is for all in one, I am not planing on breaking my boom box apart when I finished building and installing all components. I want to work with what I have and just integrate some kind of bass.

NOTE: Weight does not matter to me as I want to keep it small in size.

a t24 would be best suited for you, an autotuba is just too small as you would get no output halfspace. it wouldn't be much larger than a dual at
