im so pissed
im so pissed i got the Alpine SPS-1005 Tweeters and Alpine SPS-170A 6 1/2's. put them in on the driver side so far. they are not half as loud. n dont even sound better then stock. is it goin to be diff after i do the other door. i dont even want to do the other one now. the tweeters arnt louder cleaner or higher or anything. only question i got is when i installed the tweeters i left that bulk thing i think is a mini crossover that connectes to the stock tweeter. should i have felt that in there?
did i do anything wrong? dont think i really could have.
happy hoildays

yes you need that "bulk thing" it is a crossover and will only allow certain frequencies to the tweeter which will make a dramatic difference. Also do you still have the monsoon cd player? The stock speakers are 2 ohm and your alpines are 4 ohm which is only getting half the power your stock speakers were which is why it doesnt seem loud. get a small amp and hook them up to that.
i wanted to leave that amp because i looked at the fourm thing and they said that would work. i dont have money for an amp. they said it would be better and raved about it it even has a stick at the top of the pag but its but what was expected at all? u thing the ohms r ****** up with only half the car done?

well i did the other side today and i have to say im disappointed. its not as loud. b4 i never turned it up all the way today i did because it wasnt enough. clearer i guess to a point. but if i have it up and the equiler is up on the tweetwe part it gets nasty. this sucks i was hopping for better. nething i could have done wrong?

Are you telling me that 200 watts is just as loud as 100 watts?
The Monsoon amp is rated at a 2-ohm load so putting in 4-ohm speakers will reduce output. It doesn't actually reduce the power capability of the amp - it just means that more power is dissipated as heat trying to drive twice the load it was designed for, so the volume is lower. In other words, the speakers aren't changing what the amp is doing but the power isn't being used as effectively on the higher load.
It takes ten times as much power to produce twice the volume so doubling the impedence of the speakers doesn't cut the volume in half but it does reduce it somewhat. Also, the OEM speakers are not very efficient so installing high efficiency aftermarket speakers (even if they are 4-ohm) will keep the volume difference from being quite so big.

This is exactly what your manual says - a 200 watt rated amp will put out 200 watts into 2-ohms but only produce half the rated output into 4 ohms.

With this setup (for under $300) the radio sounds WAY better and is plenty loud enough for t-top off cruising even with open headers.
Your Alpines should be able to handle 50 watts and yes they will sound tons better when not hooked up to the factory turd amp. There's no way to make that turd of an amp smell like roses, so bury it!
what amp u guys suggest? should i have it push the mid bass subs or jus let them be. the mid bass subs will b the RF subs. what power level should i look for?

this will determine the amount for the fronts and mids.
a good range is 35 watts rms - 75 rms. It just depends on you power to the subs. I mean, if you are pusing 2500watts rms to the subs, than obvious, having 35watts to the mids, etc won't be loud enough. you could always go for 75 rms and turn down the gains, this will leave you open for upgrades in the future. I mean, if you wanted more bass down the road, you won't be left stuck with not enough power for the fronts and mids. Does this make sense to you?
im talkin the mid bass subs. i have plans for subs (brahamas 
)but thats a while from now. i have the alpines up front and rf coming in soon. the ones that are on the sticky with upgrading the monsoon system.

I used to be an Alpine installer and I am a big fan of their equipment. Their V-Power series is a good cheap amp. You can pick up a MRP-F240 to power them very nicely and you can add a pair of new speakers in the far back to run too. Or if you can find a decent lower power pair of 4 ohm subs (such as the Koda 6 mentioned in the sticky thread on top on the last page) you can pull your rear subs and run those off the other two channels on the amp.
