Hey guys, I have seen a few threads about people replacing the stock crap subs in the rear deck with 8" subs. through the research I have found I can only come up with 2 subs that are "free air" or "infinate baffle" capable, meaning they can me mounted to the rear deck like this and not in an actual enclosure or speaker box. the ones I have found is the Kicker comp 8", or the Alpine type-r 8". I already have a Kicker 300.1 amp that I will be using to power these, so I am now stuck trying to decide which to buy. obviously the alpines are a bit more expensive, but they seem to be of better quality at least looking at mfg specs. the alpine is a dual voice coil that is rated at 300/900 rms/peak, where as the kicker is a single coil rated at 100/200 rms/peak. the mounting depth is close to the same kicker is 4.25 inch alpine is 4.5 inch. at this point I havent decided on what brand of speakers to get for the doors or rear pannels either, not sure if i can afford to go with alpine all around. I will be using a Pioneer AVH-P4300DVD head unit. what are you guys suggestions for subs/speakers? what have ya'll used?
