[QUOTE="blazian87, post: 8328123, member: 574798"] Ok I'm gonna give it to you straight. There's two ways you can get louder: Either more cone area or more power. Going with bigger woofers like 15's in a bigger box will automatically get you way louder with the same amp. That's the cheaper route. Adding a bigger amp means you need the extra power to back it up. Even with 130a alternator, you can only go so much before you have to upgrade. You can try getting a 2nd battery, which will help but it just depends. Most likely you're gonna need a battery bank to even run the SQ2200 amp. The difference in swapping subs might be minuscule at best unless you add double the power. If you decide to upgrade amp, find the biggest battery you can and still be prepared to buy more if need be. There's no way in hell you're gonna run 3000w on stock alternator without a big battery bank. Really though, the cheapest way to get louder is to utilize all the space in your truck you can. If you can't fit 15's, then you're stuck. You can possibly build a 4th order bandpass to get louder with your 12's but that also takes up a lot of space. Make sure you get your big 3 done and run 1/0 ga OFC to get the most out of your amp.
