Stereo & Electronics - Questions Regarding Amp/Sub
05-30-2012, 01:01 AM
I replaced my sail panel speakers with Kicker 10cvt6.5 only to realize the problem is they want 150 watts a piece, so im going to get an amp to power them separately and have the rest of the speakers powered by the monsoon system.
Any suggestions to power 2 150rms 2ohm subs?

any ideas? im not sure if i should get a mono channel amp or a 2 channel amp?
and I am also lost as to it being a 2 ohm if i need a 300 watt amp or not?

RE Audio XT-1600.2V3 can be had for about $100.
Try to get a two channel class D that runs 150W RMS x 2 @ 2 Ohm. I would not get a monoblock to drive the midbass, as they can reach freqs up to 300 Hz depending on how you set up your crossovers, which some may perceive as directional. Plus this two channel solution is more cost effective for what you're doing and simpler to wire up.

Would that work? I have a buddy that has one for sale, but wasnt sure if it was what i needed

Same available power, but the crossovers are non-adjustable. I have doubts about how much sub-bass (below 100 Hz) an inexpensive 6.5 can push out and would run an LPF that low on them. But other than that, yes... it should suit your needs and work fine, and drive the speakers adequately.

The listed frequency range is 25-350hz if that matters? im just trying to learn all I can before I install the amp

You're talking about the frequencies the speaker can reproduce, I'm talking about filtering (on the amp) the frequencies you send to it. The RE amp I listed has a nice, adjustable crossover knob. The kicker amp you listed has a simple switch for HPF (80 Hz) and LPF (100 Hz) with a single preset value.
The Kicker amp will be fine, just set it for LPF (100Hz) or turn the filtering off. Or if you want to send those subs a larger range, get the RE. Both will work, one just gives you more flexibility. That's all I'm trying to tell you.
Smaller diameter cones typically won't do freqs below 100 Hz nearly as well as larger diameter cones, and your smaller subs would probably excel in the 100-300 Hz range, where a 10" or 12" would do better below 100 Hz. So, if you want to be picky, an LPF setting that goes higher than 100 Hz may be beneficial for your application. Smaller cones can rival larger cones in sub-bass performance if they have a higher excursion (throw range) but typically shallow mounts aren't made for high excursion.
