[QUOTE="HardofWhoring, post: 8831120, member: 674149"] Honestly, Unless you want it LOUD. I think with what you are sitting on, and the limitations of the vehicle. I would just run the rainbow components up front, get an adapter to run the 4" in the back, and get a head unit that will do 50w x 4 to power it all. Otherwise, you either need to buy a set of components for a few hundred that will run about 150w that will fit up front that will fit, or buy a 2ch amp for just the back (but then they will overpower the front). If you buy a second set of components you are now also running that amp at 150w x 4 =600w then / 14.4v = 41 amps / .85 (85% efficient amp) = 49 amps you are adding to your draw that you need to plan your vehicle's electrical for. (An older vehicle probably has a minimal alternator on it now). With wiring, fuses, components, alt, you're probably $500 - $1000. If you buy a head unit that is 50w x4, you might spend an extra $30 for one compared to one that isn't. You can hook up everything you have, try it out, and worst case scenario you spent a few bucks more on a head unit you might not have gotten, but it gives you options. Then all it is, is you are right back in the same spot you are now. You know how it all sounds, and THEN you would just need something around 150w rms that will fit up front, and the 6.5"s and amp are sitting in the closet ready to go. Unless you have head unit you are set on, or want something that is more old-school style, you buy a small 50w x 4 amp for em (which is about $100-$150). [/QUOTE]
