which is better? a 3 way or 2 way speaker (which sounds better?)
Im looking into the Infinity 6x9 or the Alpine 6x9 (the newest models... forgot the names)

In Comps, a well designed and installed 3-way system is hard to beat for power and clarity. An optimized crossover for same, makes all the difference.
As for coaxials, I prefer a quality 2-way over a low budget 3-way. Cheap crossovers, poor linear performance of all 3 elements, MB,MR & tweets just leave me looking for a better way. Some of the newer 2-ways actually have a removable tweeter and phase plug to replace the tweeter. Some even use a good 12dB crossover too.
I think Bahn has a 6x9 with this feature. To get the most from it, a good enclosure for the 6x9's can improve MB performance considerable.

im actually looking to mount them in the side panels in the back seat (replacing the stock speakers) i got a new.... ok not new but new to me car
1987 Chevy S10 Blazer (my caddy exploded... took it for emissions and the guy walks up to me while im sitting in the waiting room and says... sir your car exploded - obv i almost made a mess in my pants but it turns out the engine blew, i slung a rod into the oil pan, AND the thermastat went out and blew frion all over the place....) turns out an alt will be ALOT cheaper for this anyways so im happy

also swez - what did you mean by a push and pull fan system? and which of these fans would i want to use?

They both have the same specs on the box style fan and Stinger is much cheaper. Probably the same maker, just a logo change.
Push/pull means... one fan sucks warm air out near amps, other pushes cooler ambient air across the amps. The fans usually work best when the amps are encased and you create a wind tunnel effect in the chamber they are ventilating.

PS Fans can be noisy too, depending on CFM ratings and speed. Keep that in mind as you plan the install.

how would i encase it? fiber glass?
swez on 04/15/2005 19:44:10
Fiberglass, Plexigalss, lexan, or yes, even wood with perhaps a plexi window. Can make a platform to install your amps on, then shrowd it in a manner most pleasing to your tastes and then add the fans.
It does not have to be perfectly air tight, but enough to force cooler ambient in and exhaust hot air out.

so it completely surrounds the amp correct?

Yes, you have a cover encapsulating the amp(s) and fans at either end to pass air through the chamber. It might be good to use a containment system that is 2-3 time larger than the amp for plenty of air movement to pass over the amp.
Most amps are ~3" high. A 4-6" tall cover over the top of the amp should work pretty well here as there is more moving air in the chamber this way. The trick is to design the cover so it overlaps the amp mounting system (a flat board amp rack if you will) and allow you to push adequate cool air across the amps heat sinks and casing.
FYI: There are various air directing methods that will work here. A simple method that come to mind would be a plexi air vent that magnetically snaps on to heat register vents in forced air furnace outlets. They are often adjustable in length, sturdy and you can mount the fans in such a way as to force air down onto the amp w/ a fan(s) and it will vent heated air out the mouth of the vent. That would work and be a very cheap and simple method to do the job.
Something like this should work out. The trick is fan mounting on a curved surface. I have see flat ones too.
