Maybe it's the nozzle. Try pulling it off and soaking in paint thinner or mineral spirits and see if that helps. Any of the spray adhesives should spray fairly light and even.
Thanks for the pointer. I'll give that a shot.

Have you hooked the TruckTuba up to anything at all, for a listen yet?

Still not ready with the stereo for the truck so may give to a friend to try out and get his feedback comparing it to his direct radiator sub...
My guess is you will be building a second truck tuba soon. Your friend may refuse to return this one after hearing it.

Ha, the thought crossed my mind... Now that I've built one, I think I could knock out a second one in less than half the time. I plan to take it over this weekend, so will be sure and report back how it sounds.

Update:
I dropped the truck tuba off at a friend's house the other evening so he could test it out since my Excursion isn't ready. He just messaged me...
First, the good news: it's to big to fit anywhere other than on the back seat of his F150, so no worry about losing it...
The better news: Sounds great. Coming from a true audiophile, I'm excited. In his words, makes his pair of JL subs sound "like Sesame Street" and takes very little power to push it, sounds really good at low volume too. I can't wait to hear it.

Have you bought an amp yet? Just watched this video and it has me slightly piqued about this budget Walmart amp... JENSEN XDA92RB Class D 2 Channel Amplifier

It tested 263 watts RMS bridged into 4 ohms (only rated 240) at 1% THD, 284 watts at clipping, and a little over 300 with dynamic burst test. More than you'd need and, at $60, the price is right. Plus it has some basic DSP that's controlled via bluetooth and an app on your phone.

Already picked up a brand new little Boss A/B monoblock off Amazon warehouse for 40 bucks. Should be more than enough juice for my needs in the excursion.

That's awesome...

"Hey friend (taps fingertips together, peering beneath his brow with a devilish grin), come over and listen to my $40 amp powering my $35 8" sub I put together with scrap lumber I had laying around and tell me what you think."

:twisted: Bwahahaha

Gonna be epic!

Yep, that's the one. Just watched the video. I knew it wouldn't be anywhere near what Boss says the output is,. but I figure a hundred honest watts into the 4ohm MCM in my truck tuba should be more than enough. I like that he says it's super reliable, so we shall see. Got until Jan to return it if it can't cut it.

Too bad the FTC doesn't keep the industry honest. 1100 watts with a 14v supply is 78 amperes, and that's at 100% efficiency. That much draw on a continuous basis could toast your alternator.
