Amplifier selection

[jbhepler]

I need help selecting my new amplifier. I've narrowed it down to three. A crescendo symphony s1 plus,ruthless 2300.1 or D4S jp23v2. I will be running it at 1 ohm. Any help would be appreciated.

Also The amp will be pushing 2 Kicker L7s 15 4ohm dvc. Also been thinking about the sundown sia 2500d. Would love to hear opinions from you guys. Thanks.

If you don't have a superb electrical system better not run a full bridge amplifier, stay with half bridge amplifiers. Success with those subs depends a lot on the size of the box, those subs will work best on 4-6 cubic feet net per driver.

I went with the D4S jp23v2. Couldn't beat the price per watt and the knob is sweet. I'm designing about a 9cu ft slot ported enclosure for them so it should slam. Not sure on the tuning frequency yet since it's gonna be for everyday listening not just SPL. Looking at the low 30 range. Not much on the electrical. Stock alternator for now. Big 3. 0 gauge ofc. 55ah agm up front. 64 ah lithium headway in the back.

That amp is half bridge so it can run on lower voltage say 11V or so without issues, your alternator should be 180-200A for better results, also to note that  the amp needs to be placed where there is good ventilation but not on the box if possible. Port area for the box should be about 55 square inches PER driver so about 110 for two drivers.
