I have a sony xplode cdxgt240 head, a 300.1 amp with LPF freq, input level and bass boost and 1 12" alpine type r with 2 ohm impedance.

I blew my rf p2 out so I wanna make sure i don't make the same mistake here.

input level 250mv to 4v (the preout voltage on the head is 2v, so should I set this at 5oclock to make sure it's not clipping? or am I looking at the wrong voltage)

LPF frequency is 32 - 320 so I set this around 4 o clock and bass boost I currently have at 0.

On the head I have my lpf filter to 80 and my hpf to 120 and the phase thingy is set to normal instead of reverse.


what tweaks should i do to ensure I don't blow out this sub.

 

Really, nothing on the amp is going to ensure you won't smoke your sub. Knowing to turn it down when it sounds bad is the key to not blowing up speakers

 

Thing is, I don't know when it sounds bad. I'm a guitarist so when I hear the term 'distortion' i think of something completely different. Or it isn't something i've heard yet LOL.

 

i doubt that amp will blowyour sub. are you using a sealed or ported box?

 

It's a sealed box, just a q logic.

 

I Have a sony head ubit that has a LPF on it I tried it and it sounded by with it on I just use the low pass filter on my Amp I have it set to I think 60 or 80 if you have yours set to 4 oclock that might be way to high mine set to 80 it at like 9 Olcock AM.

 

Also set your gain as low as possible I Had a Fockford segate Punch amp I think or maybe the one before it and with the gain just alittle bit up is sounded the same as all the way up now I Have a Pineer and it have a setting for normal in the gain and that to is almost maybe a 1/4 turned up thats it if that.
