First, you need to know what the specs are for your speakers
T1652-S - 2-woofers -100W rms - 200W peak
T152 - 2 woofers - 75W rms - 150W - peak
2 tweeters - 75W rms - 150W peak
I have no way of knowing if you are planning to use one amp to drive all 3 sets; or one amplifier -per set of speakers-Anyway you need about 250 WATTS of power to get max efficiency and the best sound but also keeping it safe so as to not blow up your amp or trash your speakers.
First of all, I would like to congrads you for going about this task in the proper order because most (if not all) people would go out & get the amp they want and then have to try to match speakers to the specs of the amp. If you start with the speakers its much easier to gety an amp that is best suited to the task at hand, as well as a near perfect match to drive thwe apeakers for optimum performance
So I am looking to change my speakers and deck since they are garbage, I decided to get Rockford Fosgate T1652-S component system for the rear, and T152 coaxial for the the front. My questions are how powerful should my amp be and do these speakers alone produce a decent about of bass nothing crazy.
