Alright, I'm sure you've read it before and probably been through it; someone bought a setup and loved it but is no longer enough for them. That is also me at the moment and that is what this is about. What I have: 2010 Chevy Malibu 2 12" fully loaded Fi Q 12s in a sealed enclosure approx. 3 c.f. (built for sealed because of lack of trunk space for ported box) no upgraded alternator (reason: not easily accessible and no one pimps these malibus, so they don't make those componenets and when they do, they're expensive) 2400 Kinetik battery in trunk bigger battery upfront (duralast platinum/gold whichever they said was better, lol) Hifonics Brutus BRZ-2400 0 gauge and big three, but no dimming or anything at the moment setup wired to 1 ohm What I want: to be significantly more powerful but still have great sound quality (on the highway) to still be able to get quality bass also at lower power levels (when crusing through the city) What can I do to get from where I am to where I want to be? 1. will more power to the Q12s make a significant difference? or would the difference in power be miniscule as the subs may be close to peak performance at 2400? 2. Would the BTLs be the way to go to get that BOOM? heard they need a boatload of power to actually make them much different from the Q line **just from what I have read, no personal experience** ANY/ALL advice is appreciated. know how to help me out? please do! Think I'm doing something horribly wrong? tell me! P.S. installed my first system 5 yeas ago and have done 4 since, not a bass expert but know more than the average Joe
