Your CAB-M4 has several different warranty options available. To keep the price as low as possible, the base amplifier carries a 90 warranty against manufacturers defects only. This warranty does not cover damage done to amplifiers from miswiring, blown speakers, low voltage, and other user errors. The premiere warranty tier (79.99) covers practically all forms of damage done to the amplifier for 2 years. This premium warranty also has a graduated deductible associated with user error failures to avoid intentional misuse of the policy. In the first 12 months, the first use has a 0.00 deductible, the second use has a 50.00 deductible, the third use will have a 100.00 deductible. the 4th and all subsequent uses will have a 150.00 deductible. If the first use is in the second year, the deductibles start at 50.00 instead of 0.00. This warranty is non transferable, and is only valid for the original purchaser.

    The best you can get for the money.

    Posted by Robert Davidson on 9th Mar 2023

    I purchased one of these to play with and see what I thought. A few days later, I ordered 3 more for a total of 4 to replace my 4 DC Audio 175.4 A/B. That probably sounds crazy but so many amps advertise bandpass filters and they don't work. The DC 175.4 for instance only crosses over up to 300Hz. Why on earth have a BPF if it only goes to 300Hz? It's completely pointless. I also had the Crescendo 2000.4 and couldn't get that to work. These amps have bandpass filters that actually work. So I have 4 amps that do exactly what I tell them to do without the need for a DSP. l have a total of 5 highs amps that are all 4 channel. And when you have that many 4 channel amps, DSP setup can be a real nightmare. You actually need multiple DSP's. But with these amps, I set one for horns, one for mid bass, one for tweeters, and one for vocal 6.5's. Cutting off the top and bottom end wherever I need to for each amp. Making them play exactly in the range that I want them to. No more DSP woes. They put out excellent power and they have tiffany style RCA's (which my $660 DC amps don't have). The only complaint I can come up with is how sensitive the crossovers are. It makes dialing them in perfectly a little time consuming. But man it's worth it. Exceptional amp for the money. A bandpass filter that actually works. Imagine that.

    Cab m4 and 22

    Posted by Ryan amen on 28th Dec 2021

    Im going to b straight foward with 2 cons for both the cab 22 and m4...1st con is the quality control on heatsinks...they need to b deburred and checked for deformities such as bent fins and scratches...seems as if they slice a bunch up n jus toss em in a bin...both my amps came with theese defects...does it hurt the performance?...not a damn bit!!!.. 2nd con is just personal preference...phillips bit set screws...GET RID OF THEM!!.. THEY STRIP WAY TO EASY..i replaced all on my bass amp..phillips and tightening down 0 gauge is not a fun process together.. both theese cons can b fixed and addressed with little to no cost to keep prices the same...now that thats out of the way..very very very impressed on the power theese boards put out...they sound clean...even at full tilt...running 4 pro mids and tweets off the 4ch and the gains are barely cracked...and to stay sounding that clean when i have the channels loaded to 2 ohm...kuddos...as for the cab 22.... .5 ohm daily on a set of 15s for 3mnths now no probs...give em clean power and airflow n theese things will outperform other budget manufacture 2ks easily...even the ones that look like usamps reprints lolol (sry johnathan)...all in all def worth ur money if on a budget!...fix the 2 cons 5 stars all day n night long...cant wait 2 get another 22 n strap...easy 5k budget there...gud job audio apex...and stay in the game...we need more options such as you!
