Boss a$$ amp, Amazon special prices, SUPER BRAND, super high end QUALITY

Well I have a 3 amp system I'm still tryna get all together. This amp has a super small footprint being a almost 350watt RMS. '80wx4@4ohms=80w@4ohms;{160wRMS@2ohmsx4!}
("RMS"... That's another thing I like about CT Sounds. CEA Rated RMS at the most common ohm load is displayed.... Unlike 90%+ of others who put the 'Mysterious', pulled out someone's anus, '"MAX" Wattage' that you, anybody in your family, or even the amp is EVER GOING TO SEE,... where TF do they get the legality to take an RMS wattage, and multiply by two, BAM!
Amazingly misleading, perhaps prompting, "new to car audio" people to buy half the power they needed/wanted/thought they were getting.
My CT2000.1 puts out, a very convenient...
2,000watts at 1ohm (most common ohm load these amps are seeing wherever in the world they are being used)
Original plan was to run 8, 6.5" CT Bio PRO AUDIO mid drivers off the CT150.4,
But I have four of them in my TWO DOOR 05' HONDA CIVIC
In each two doors, is most of my soundstage. Consisting of
_Ch#1&ch#2=door#1, *150.4
I have 2 CT Bio 6.5"s ran parallel at 2ohms getting roughly 125watts each (250w@2ohms, shared),
With two 3" midrange speakers per door
(100wRMSea_1.5kHz-18kHz_104db. RATED)
On CT80.4a/b using Ch's 1&2 @ 2 ohms also running 2 4ohm drivers in parallel
160\2, roughly 80wRMS to each 3" mid range
Ch3 on 150.4 drives 2 Deaf Bonce Hannibal 6.5" PRO mid bass drivers (110-115Hz out to 3.5khz. 80wRMSea. 97dB)
CH4 running some pro 6x9"s (115-10kHz. 100wRMS ea. 95dB)
CH3 on 80.4 running 4 8ohm super tweeters, and CH4 running some compression horns

To be honest, I never had a matching set of amps, especially not in the amp class circuitry configuration,
That sounds so amazing, I have had smaller and bigger systems, more budget+more expensive, and even 3 dB Drag competition SPL VEHICLES, built about a dozen,
In the 20+yrs I've given to car audio CT Sounds *PRICE PER "QUALITY" WATT*.... IS NOT SURPASSED....
It's actually laps ahead, with no one even creeping close (behind)
This is my "Budget Build" since my big build got put on hold do to SUV being totaled while parked by dumb drunk driver...
But if that didn't happen, I wouldn't have had the use for/a reason, to try out

Super glad I did...thinking about getting some OZONE 10"s to replace the 10"s I have now, which are also 800rms each, but CT Ozone resonant frequency is like 8Hz lower than my Audio Legion Gladiators...
And they're still not out of "budget" territory 👍💪🤘🤘💪👍

CT-80.4AB 4 channel amp

When I opened my box it was packed good and tight with the other products I purchased. I am going to be using this amp for a wagon build I am working on for my youngest son. I haven't installed it yet but the compact size will help with the limited room I do have for the electronics.

CT sounds is legit

The amp doesn't get hot and pushes 4 strato 6x9s and 2 tweeters no problem,they sound crystal clear and scream ,I can't wait to hear the 6.5 3way componentss on the 150.4 💯💯
