when amped, that speaker adds much needed midrange to the front of the car... but only untill it melts. :? I put an infinity 1 way 6" there that I bought at a pawn shop, and powered it by a one channel amp. with all other speakers stock, the stereo accually has some bass without a sub. I think it would sound even better with one of those ukrainian tire speaker cups for something for it to fire against. it only puts out lows and mids, and dosent hurt the LR balance.
this just gave me an idea... im going to try mounting another on the drivers side for mids and bass. while I had the panel off I saw that theres definately enough room. I listen to alot of Rock, and the punchy mid bass is great for it.
Im not kidding either, this sounded better than having amped 6x9s in the back. and took up less room.
planning on adding a sub again though, now that my rear spoiler dosent rattle. an 8" or maybe a 10"
after all, a lighter car is a faster car.
