[QUOTE="trumpet, post: 8524854, member: 628688"] You really don't need 150W x 2. Yes, 75W x 4 to run mids and tweeters active will do just fine, but you must have the right crossovers to do it with both good sound and reliability to not smoke the tweeters. Another note that was already touched on: 6.5" speakers are not going to play bass. It's not clear what your overall system will be eventually, but you need to add a subwoofer to get real bass. Generally speaking, if you want it loud on a budget you will be crossing the 6.5s at roughly 80-100 Hz, and a subwoofer will play everything below that. Some people will cross 6.5" woofers below 80 Hz, but there is always a compromise. In my experience that sacrifices midbass punch, distortion increases dramatically, and you add to the risk of over-excursion which can cause damage. Option 1) Get a passive 2-way component set, get a good quality 4-channel amplifier, bridge the amp and upgrade to an active setup later.
