[QUOTE="2023 LTZ, post: 8841106, member: 686684"] It is preference. If you look at the wattage of that single sub and compare it to the fifth channel on the amp and choose either 1 or 4 ohm based on that fifth channel’s output at your chosen ohm for the sub. Some amps are stable or capable of playing at 1 ohm and others are not. I chose to have separate amps. One 4ch for the cabin speakers and one for the subs. If you haven’t checked out Crutchfields articles on almost anything relating to audio components, there’s a lot there. For instance the matching of your sub and an amp and at what ohm works for both or all pieces. Very few full range speakers come in anything but 4 ohm. True some do but those 690s are 4ohm. A nice 4 channel will power those and another set including tweeters. Use the provided crossovers to ensure you don’t blow the tweeters. Some choose not to cross over the other 1/2 of a component set but imho the amp is fully capable of delivering the power to them even w cross overs. Use the Crutchfield site to learn about your stuff maybe that jl amp will be perfect. [/QUOTE]
