Question about SPL Audio Car Audio & Video
Not knowing what you have the SPL-620 driving or knowing how you have it wired, it's rather difficult to determine if it's wired "wrong".
I show the SPL DK2-620 as being a 2-channel amp with 150 watts output at 4 ohms, or 180 watts at 2 ohms. Even if the power is somewhat overrated, it should provide more than enough power for a set of standard 2-way or 3-way speakers, or component speakers with a separate crossover.
Powering one or more subs is another thing. You would get sound, but the subs would not be very loud. In bridged mode, the amp is only stable to 4 ohms. So if you are trying to power 2 4-ohm subs, the best connection would be 1 sub connected to each channel. If you are powering only 1 sub, then the bridged connection would be best.
Hope this helps. If it does, please rate as "FixYa".
