      I forgot if it auto senses the signal and switches or you have to hook up one or the other.

      You have to manually hook up one or the other. If you connect both you will blow the amp.

      Ah so the "Line" connector uses the amp on whatever board instead of the built in amp of the blast?

      It's the other way around. Line needs to be amplified with the Blast amp.

      It's referring to Line level audio (pre-amplification) and speaker as in post amplification like on a car amplifier where inputs can be speaker level (or high level) or line level (low level).

      I was speaking in general terms. Line level would be using the cabinet amp , just like if connecting your car stereo to an amplifier using RCA/phono leads you are feeding the amp line level audio. If you was using the stereo speaker outputs to drive the amp they are high level ('speaker') outputs as they have already been amplified.
      Older cabs didn't have amps in them hence the volume control on the boards.

      I've tried the 3d printed speaker replacements they don't sound nearly as good as the original toptone drivers. Toptone themselves don't produce the speaker any more, and I can't find anyone else who makes them in that dimension either, let alone ones that sound same or better. I have a bunch of original drivers, but they mostly suffer from the foam rot. This is why even buying "NOS" ones is not a great solution because they may be soon to rot as well. Really we need someone to make a refoam kit, but I'm not an expert in audio engineering by any means. I know there are refoam kits for other shape drivers, but i don't think you can easily make it work. If someone wants to point me in the right direction as to what type of foam is good to use, I can try to make some 3d printed stencils to cut the shapes out with.

      maybe contact parts express to see if they can make a refoam kit. They make them for lots of other drivers. They may already have a kit in the right size.

      I’ve been working on a replacement enclosure with better drivers. These will be rear mounted since they are bigger full range drivers.

      I have however laser cut new fronts to the originals boxes and mount a new driver array and they sound pretty decent. But everyone wants more low end bass ^^

      That's cool... I was actually thinking about doing something similar because I wasn't satisfied with the other replacement speakers' sound. I am curious what the low end is like, do you have a spec sheet for those speakers? or part no?

      How are you modifying the amp to double the amps? That sounds interesting...

      I'll look up my order, they are on parts express, the best I could find that would fit such a narrow space. They are not bad. I was thinking of adding a side mounted passive radiator to the original case to see if that improved the low end response. I still think a new custom enclosure is the way to go. I just feel like these speaker where an afterthought when sega created the blast, "oh shit, we forgot about speakers, let put them here" lol.

      The amp, is still in a test phase. Im still sorta reverse engineering the schematic/component values to see if what Im thinking of will work. Im trying to make it a simple upgrade.
