Honestly, you could go with a 1000wrms sub and still blow it with 500wrms if you turn the gain or volume up too high and send the sub a clipped signal. When you get this new sub, get the installer at JB to set your gain properly.....Ive used plenty of those Jaycar amps and have found they dont power subs all that well, theyre great for powering speakers but fail for subs.

Let me get this right, JB replaced your sub, not once, but twice, and then gave you a voucher on your 3rd visit?
Bend over JB HI FI lol

Bass boost should be zero. Read: Tutorial - Amplifier Gain & Crossover Adjustment

You're not listening either, your gain can be low and you can still kill your sub if you turn the volume on the head unit up too high. The reason they blew would be because you just had them playing too loud.

Yeah, JB are morons. Ripping off the distributors because customers damage their own gear. I see this nearly every day and it's extremely frustrating when distributors are nearly going out of business. Which JB HiFi store is it?

^^^ Agreed with StoneX. It dosent matter where the gain is set, it is primarily a "tuning" tool so you can intergrate it with the rest of the system (so all speakers get to their maximum output at the same time on the head-unit volume).

Im not quite sure why the Response 2 x 150 dosent power subs well.....i think it has something to do with the frequency response of the amp and it has a dip in this response throughout some of the sub-bass frequencies, but dont quote me on that one ;)

As i said before, when you get your new sub......get a pro to tune the system for you, and let you know the maximum volume (on the h/u) you can turn it up to. If that output dosent meet your requirements, get a better (more powerful) amp. Simple as that.

Yeah, but they're not meant to do that... If a speaker is blown, they're meant to send it to the distributor to be assessed. They will determine if it's cooked (user error) or a manufacturing fault that has caused it to fail. They have the distributors by the balls and rip them off flat out.

Anyway, be careful with this one... Don't turn it up so loud and it probably won't blow :)
