No I did not... I just guessed at 5K when modeling the box... Winisd said it would be around 3500 actual when I inputted 5K but I also left some room for error and made that the ABSOLUTE top end when figuring the port... maybe I got this one close... finally...

If you fellas do not mind I have another issue I really need to address. Alternator whine. An the occasional high pitch noises my external equaliser is giving off.. For the whine I'm looking at getting an RCA ground loop hope that works.. But for the high pitched noises coming from my equaliser, anyone know how to address that issue?

Check amp(s) for proper and tight ground try swapping with other rca/patch cables, have alternator tested for bad diodes

Run rca cables opposite side car as the power wire(s) for amp(s)

My battery under hood/bonnet is left side so I run power that side and run rca cables opposite.

I know for sure.. Grounds are absolutely solid contact, did them myself professionally. RCAs are dual shielded plus have cloth tape on all my cables for extra shielding an heat resistance.. RCA an power cables both ground and power cables. I wonder if you guys that too. What name brand cables do you use... OFC? Braided? Shielded or double shielded or not shielded at all? Could it be because of high outputs from amp... Wth is it cause this shisha noise.

I bought cables from amazon a few years ago, cant remember brand. Nothing special.

Some headunits like mine are sensitive to hot swaps and will fry the pico fuse causing this whining sound. I have had 20 radios over the years probably and its the only one with that issue but others have had it too.

I'v had thus issue every single time in every after market headunit I'v owned. Just won't go away

Spot on with those measurements. 3200 watts heat rating or rms?

Wtf is heat rating?

Only up to 15 characters allowed, so I have now changed to Bassman999 as used on other forums

Ridiculous they limit you on screen name characters....

get rid of the equalizer and get a proper head unit with a proper built in EQ. Too many things in the signal line just calls for horrible noise.

Usually alt whine is bad ground or RCA's.
