[QUOTE="HardofWhoring, post: 8842648, member: 674149"] You never really know with amps. They could last another 30 years, and they could go out in a week. Here's a place I always check for deals. They have a couple of low priced amps, and even a package right in that price range you mentioned for used. I have some hertz amps, and I like the quality, can't compare it to some of these other ones listed. [URL unfurl="true"]https://www.woofersetc.com/sale.html#limit=20&mode=list&order=price&dir=asc&p=3[/URL] Don't sell yourself short. If you're here doing research, you are ahead of most people. There is plenty of information to help you if you wanted a ported box, to hit harder. The big 3 always helps. For electrical, here's how you can figure it out for yourself and see what you are working with. amp wattage (lets say) 600 / amp efficiency( / .85 for usually 85% efficiency) = 705 watts draw for your amp to produce 600 watts. 705w / 14.4 (voltage) = 49 amp draw, when that is full on.

Before you buy subs, I would suggest you look into larger alternators, just so you are aware of your options and see how it fits in your overall budget. - If your lights dim, your circuit is not good enough. - If after listening to it for a while, and your battery voltage drops, then your alternator isn't charging enough.

Worst case is, you have to shut your stereo off for 10 minutes before you shut it off to recharge, (and that's if you have your lights on, your AC on, your turns on, play with the windows, are charging a couple phones, and really putting a strain on your factory electrical. Building an enclosure is not difficult, but if you're on a tight budget, you might want to figure out how much materials cost, and what tools you would need to buy, and the time to design and build. If you don't have the tools, and any generic enclosure will fit, that will probably be a better option. As for subs, if it has a part or model number you can look that up easy.
