I purchased a pair of GB12's from a member here that will present a 2 ohm load for the amp. I'll be running them in a sealed 2 cube box. Their rated rms is 500 per sub. Should I stick with a amp that puts out 1000 at 2 ohms? Or would it be better to run them with an amp that puts out 1500x1 or 2000x1?

If I go with a larger amp, how can I be sure I'm not going to cook the speakers?

Thanks

whats the budget? 1000 real clean watts would be better than a cheap 2000 watt amo.

There's a T1500 BDCP in the classifieds now that I have my eye on...
decent amp. Maybe a bit overpriced based on the randomness of the history. Amps just don't require new thermal paste unless the amp was opened for some reason. I would also be looking at used Mosconi, and zapco too.

I like to run double the rms rating, in your case that would be 2000 watts. You just have to be careful not to push the subs past their physical limits. I'd much prefer to turn down an amp that's too powerful than try to get more power out of a too weak amp, that leads to clipping and fried voice coils. Depending on the amp, you could go for a 1500 watt amp like the Rockford (usually under rated on power) mentioned above, but one without a sketchy past.

The GB12 subs do not need much power to get loud. I ran a RF Ti1500 bdcp on mine and it was plenty of power. 1.5 time rated RMS and then you set the gains for 1000-1200 watts and you’re good.

Look at the JL RD line. They have a 1500 now that’ll do 1500 @ 2ohm and 1ohm. I think it’ll likely do closer 1800. You can get a refurb for around $440 after discount from creative audio.

Where do I get a discount code? Anybody had luck with a refurb?

It was also suggested that I check out the mmats M1400.2. Retail on it is $670. Or the M2000.1 for $840.
