size of AWG period, flexibility is just a option for have to get to(outta way)places. i use flex 1/0awg going to the amp(s) and stiff wire 2/0awg for the big 3. i suggest the larger wire as it will help current flow and leave room for upgrade(1/0AWG) WELDING leads works great
diffenently a imaging problem, without having change spkrs location, you may be able to angle them to make up for this problem(although this may take time to get right)
mabye you should have read my reply - (oh, sorry i forgot to mention go to autozone.com or napa,ect... and put your vehical make in & engine size, look up alternators and you will know what kind of alt you have. by the way napa has some really good heavy duty stuff(battery post...
should work well, good amp(s) choice. back in the day i ran 2 orion hcca275r's on 8 savard 17-015. 15" subs. one of my better set-up's.( just remenising) love orion and RF amps. HAPPY NEW YEAR TO ALL : )
find out what other vehicals uses that alt, then look for the opional upgrade, with a small modafication(if any)it will work. also a smaller pulley will up the alt output at idle, but will cause the alt to fail prematurely(over time of corse)
god no, sensitvity 84 db???you'd better get a powerful amp. if you want to go fairly cheap pioneer has some slam'ing 10's. look at the sens. db, a spkr at 94 sensitivity will be 2x as loud as 1 at 84 given the same wattage
