[QUOTE="THATpurpleKUSH, post: 8667902, member: 615398"] You'll want to check the sizes of the alternators in your vehicles. If you upgrade your main starting battery to an AGM and do a big 3 upgrade you should be able to support upwards of 2000w rms depending on the vehicle. The Suburban likely has the largest alternator in your fleet. Figure 100a of power needed for every 1krms the amp is rated for. A vehicle with a 100a alt and a 50ah battery could support 1500rms of amplifiers. There are some decent amps out there for under $200 but it's important to do your homework on them. Look for something with a dyno vid that shows the power you are truly paying for. If you can build a box yourself you can save a lot of $$ and it will sound good and get loud. You can buy a box design and it will include a cut sheet that you can take into a lumber store and they will cut the pieces to your specs and then all you have to do is assemble them. It's a lot easier than you might think and doesn't require a ton of tools either. I would put those subs in a ported box, about 2.5-3 cubic feet tuned in the mid to upper 30s. [/QUOTE]
