No, ONLY look at RMS or continuous power. NEVER NEVER NEVER pay attention to peak. Your subs will be getting a measily 150 watts RMS each bridged. That amp will NEVER get anywhere near 900 aven if "LIGHTNING" does strike it.
So, basically what everyone else is trying to say w/o being mean is...(i'm going to come right out and say it...no offense made by it...but it's the honest truth) That equipment sucks. Bottom of the line. Sony subs are not good...at all...and that bolt amp is small and does not put out much power (150x2 RMS). Also, pre-made boxes are horrible.
Ok, you have a few choices. Sell your stuff...and buy some decent stuff with help from us. OR, make the most out of what you have.
Install really is EVERYTHING. It's been said 10% product 90% install. What you need to do, is...with help from us...design a custom ported enclosure for your subs. This will make them sound infinitely better and louder.
