Beginner building a system

[tigey]

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.

What car is it going in? Forget the 6x9's, one set of 6.5" components with doors deadened is enough for a Rockford 12". Also what model sub is it?

Sorry, what have you purchased and what are you still looking to purchase?

I have bought the items mentioned. My speakers are stock '97 Toyota full-range one-way 6-5"s and a pair of stock Toyota 2-way 6x9's. I'm looking to replace those speakers and I'm not sure if I should components or what. Also, in network mode w/the internal amp on, the high range speakers are in the back which, from an installation point of view - but not perhaps from an audio point of view - seems strange since 6x9's are so often in the back deck. I plan to go with internal amp off and power the speakers with Kenwoods, connecting them to 6x9s and 6.5s.

You dont need rear speakers if you have subs. Just get a nice component set for the front and deaden your doors.

I'm not sure what you're saying about speaker locations, bu going with 6.5" components is generally best for a good sound stage. You said you're going to power them all with a kenwood amp? So you have 6x9s in the front and 6.5s in the back?

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.

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.

ah so it's the speakers he's looking for gotcha sorry my bad. I was just using that as a general example though a higher wattage 4 channel would be better because as he's stating it he will have to run 3 amps the two he has + the monoblock 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.

his amp can produce 60 watts at 4 ohms to each of the 2 channels thats enough to play loudly on a mild build.

origonal poster - i challange you to take apart your door - and remove your stock front door speakers. measure the depth and width of what can fit in there

then you have some guideline of what can be a direct replacment swap for your factory front door speakers.

most good online shops have tecnical data sheets that state the mounting depth and other measurments that can allow you to find exactly what will fit.

you will want to also compair the rms power ratings of the speakers you choose to be in the 60 to 90 watts rms range - as they will play good off of the power avalable from the amp you have already purchaced.

also i love browzing this store

Shop the Speaker Components Department at Parts Express

True, though I don't think it'll be a noticeable difference. It may be in all out SQ setup, but at that point you'd get a different amp anyway. I have 3 ohm speakers, amp seems to run them fine.
