Sorry, what have you purchased and what are you still looking to purchase?Have purchased a Pioneer deh80-prs, Rockford Fosgate 12" sub, and two Kenwood KAC 1502S 60-watt class AB amps to power (most likely) a pair of 6.5"s and a pair of 6x9's, but I'm wide open to suggestions.
He already said he has an amp. Getting 4 ohm speakers is not a requirement as the amp can handle a 2 ohm load, and in fact, produce more power at that load. 2 ohm speaker, in this case, may even be more desirable to get more power.Yeah a lot of people and cars run comps in the front 6x9's in the rear deck and subs. Just decide what speakers you want and match he ohms and try and get a 4 channel amp to go with em. As an example go with 4 ohm components and 6x9s that both run 100 watts rms and get a 4 channel 100 watt x 4 at 4 ohm amp. Then get a mono block amp for the subs.
only problem is thd goes up when ohm load goes down. Usually not to big of a deal with subs but mids can get dirty.He already said he has an amp.
