Hello, I'm in Alberta. Been looking at a few manufacturers in the USA. I was planning on two AudioQue HDC3 18s.. but its gunna cost over $800 dollars to get the two to me, including the cost of the woofers. Mach5 is alot closer. I heard about Mach5 from a guy on CanadianCarAudio, who suggest one of the MLI-65 for a computer subwoofer. I've been looking at the MJM-18. I really do wish I had a larger budget. Original plan was 6. But the cost of the woofers themselves, wiring, alternator, batteries, and the rest of the audio gear I need for my truck... its gunna go over my budget.. I have a budget of at least 1200 for my whole stereo, but probably not more than 1500, but maybe a lil more. I'm going to use welding lead wire as my power wire, and see what I can find for door speakers (MLI-65s??) and the other stuff. I'm going to do a "reversable blowthrough" in my truck. I have a fiberglass truck top for the bed, and I'm going to take the rear window out of the truck cab, and the front window out of the fiberglass truck top, and use that RV acordian gasket in between, and put my subs in the bed, with a baffle to direct sound. So I have a good bit of space, just not an extremely high budget. How many MJM-18s would you guys run, and how much power? I posted this @ soundground too haha. I've heard nothing but good about Mach5.
