Car Subwoofer Selection Question - Voice Coil Options?
So I am going to try to stick a subwoofer in my 2016 Camaro convertible. Yea, it is a crappy solution for a less than adequate stereo, and I have to use a line level convertor from Pac Audio or Audiocontrol to read a speaker signal (or pay $1000 to decipher the proprietary digital MOST signal from the Bose head unit - pass). The 5th gen Camaro actually had a factory 10" behind the rear seat, but for the 6th gen, they got rid of the subwoofer and moved the electric motor for the top into that space. Waa waaaa.The real estate is downright tiny. I am trying to get an 8" sub to fit behind the drivers side rear wheel, and if that doesn't work it is going to be a 6.5". JL and Memphis both make 6.5's, but I think the JL 8W7AE-3 is the dream sub to fit, although it has been out of stock for a year. I have seen a lot of other installs with portable boxes, but I don't want to have to pull the thing out ever time I need to put a suitcase back there. I have about 10" of width 13" tall including the box and rattle clearance to fit the JL sub that is nearly 8" internally wide. Uggghhhh.
With the JL out of stock, been looking at Memphis. They have dual voice coils with the options of getting dual 2 ohm or dual 4 ohm. What is the difference? Is there any benefit to getting the dual 4 ohm other than theoretically I could run a TON more power into it? If I run the dual 2 ohm in parallel it will be a 1 ohm load (a little light), dual 4 ohm in parallel will be a 2 ohm load, dual 2 ohm in series is a 4 ohm load, or dual 4 ohm in series is an 8 ohm load (Don't think I could even get a decent amp big enough to run this). What is the best option to run this? I haven't got the amp yet either, so I can put just about anything with it. It seems like getting a 1 ohm sub with a one ohm stable 700 watt amp is cheapest, but will it sound the best? Is here a rule of thumb for picking subwoofer loads? or should I just wait for the JL to get back in stock and try to cram it in?
Thank you.
