Q: Need Help with Bass Amp and Cab advice, suggestions, and recommendations

Weird Title, sorry

But after finally gigging with my band again, and having the most embarrassing returning gig... I needed to post

My amp is a SWR Headlite 400w (pretty rare little buggers) which operates at 400 watts at 4 ohms and half that at 8 ohms, and my cab is a Gallien Kruger MBX 4x10 that is at 8 ohms

I am running a 4 ohm head into an 8 ohm cab, which is not loud enough at all for what I need it to do. It worked perfectly for practice, but at the gig, thats when things went south when I hoped it would have been enough but I could barely here myself just enough to know I was at least playing something. I had literally everything up, but had to turn up my limiter/compressor knob so I don't keep power clipping when I meet the threshold and risk damaging my amp

Before anyone mentions it, no, I don't want to get a 4 ohm cab. Already tried local listings and have come up empty handed, and even then if I did, I would have an 8ohm cab lying around and honestly, with the barren wasteland I live in of Southern California, there isn't a lot for me to try unless I can plan a day trip to LA for the guitar center and other music shops, and see what I can try without some guy playing the same c major slap scale (which Im fine with but there were too many last time I went there) and hogging the cables.

I tried searching SPECIFICALLY for 8 ohm (insert wattage) bass heads but only ever get things related to cabs. I have a few options such as a Harke LH1000... but IM not an amp guy, I just know more about instruments, pickups, setups, and so forth form teaching myself and learning online and wondering what are some options.

Are there any bass amps you all know of in 8ohms?
- My tone is for punk like Black Flag, Minor Threat, Crossover like suicidal tendencies, and maybe some metal such as Metallica, Megadeth, stoner like Kyuss and some weird alt (whatver genre) Queens of the Stone Age is (sorry Josh Homme lol), Anthrax, fast punchy bass tone.
What are my options/what can I do?
If I had to put a budget maybe under $1000, Im a broke college student :c, but Im not giving up my dream of playing gigs until it kills me (try me death), or I get hurt real bad and can't play.

If the head thing is something not worth trying to fix, and it be better to get a cab in 4 ohms, then Ill hopefully try to sell the cab and find a 4ohm one somewhere.

Recommendations, suggestions, helpful info, criticizing of my method of cooking macaroni and cheese, and so forth would be helpful from all of you more experienced, and grounded in the biome of amps and cab pairing

 

hmm okay, wow Im glad I posted first
The problem though is the cab i already have cannot be connected to other cabs, it allows for either standard jack or speakOn, but this cab has no output. And the head only has one speaker output, so I could see if I can find another cab that could be connected in parallel and have the 4x10 be the last in the chain

 

matching cabs... yea none of the 115-12's will work, as they can only be the last in the chain (as well as meant to be alone) I could look around for 2x10's, hopefully Ill find something cheap and maybe a days trip away

 

Yea, I figured. It does me well for home and doing funk (where my guitarist decides be humble and bot crank everything). Sounds nice for just about everything, but I will consider that mesa boogie

 

The audience wasn't complaining about me being too quiet, more so any complaints were partially my guitar player and one or two watchers, but the sound guy of the place is known for being not very good, heck he even started adding too much bass to the kick drum (both bands complained about this) and has weird ways of having "balance".

And yes i suppose/wish my bandmates cared to turn down a bit, and some... seething came my way despite me getting what I can doing the best and playing my heart out, while my guitarist flaunts his $1000 head and guitar (his cab being a B52 stealth cab I was given from my older cousin who didn't want to carry a big rig anymore), my drummer doing okay, and me struggling.

 

LoL, yea I would love to that tiny head on it (sounds good too for slapping and clean bass playing)

I'd have to look around, I got lucky with my 4x10 on craiglist, and so far haven't seen anything equal to that in a while. In fact I haven't even seen any cabs in my local area or the next, I got lucky getting this mbx for $150

 

Yea, especially when we play something between metal and punk, the next band though had a better balance than us (they play thrash metal and had an: Ampeg Svt and 4x10, Marshall Jvm 800 w/ 4x10 matching, and EVH 5150 with marshall cab). They barely graduated highschool most of them and have gear capable of easily playing most if not all types of venues before needing mics

I suppose the problem is when a lot of people still think just playing as loud as you can to the beat as opposed to playing literally together as band, because then at that point you are just a garage band hoping everything louder will make you sound better. I try explaining that to my band... and while they understand... they also kinda don't and assume the sound we make in the little cramped room we play will work everywhere else (which it doesn't)

Younger player here, but I imagine this be the same for a quarter of a century now.
