Aliexpress 1U amps for mid/ tops?

If so any specific recommendations?

Black friday deal on this is £115 or something.

This one has pics of the internals, looks substantial enough for mid tops but obviously I have no idea about reliability or whether it's even a good/ safe design.

I've bought electronic stuff like immobiliser emulators (small piggy back PCB which you fit inside a car ECU, in conjunction with reprogramming another chip on the ECU PCB it fools the immobiliser into thinking its all present and working so the car starts), electronic steering lock emulators etc for Mercedes cars and the only issues I had were dry solder joints on some boards. Re-flowing the parts fixed them every time.

I've also had no issues with refunds/returns on aliexpress.

These were all kinda small purchases though, no more than £25 at risk.

Any thoughts other than "its rubbish don't touch it" ? :)

yikes, nah

doesn't look like one of the current chinese designs being kicked about, so would avoid it.

as a general rule for china stuff, i always look to see if the company has a presence / branding / website etc. this is basically dropshipping, so there is no reason for the company to offer any guarantee.

having said that, it is very cheap!

Yeah I mean some of them don't have any pics of the internals either, dodgy as! I saw one amp for sale on amazon and a reviewer showed the internals and it was basically a 60w amp rattling around in a 1u case. Atleast this one has somewhat filled the case with the PCBs.

I'll do some searching to find a company with a presence then and social media reviews/ reddit etc.

If the normal aliexpress 90 day guarantee works it may be worth a play I suppose. I have some old minging but working speakers here and could run it for a day or something to ensure it's not DOA.

For Sinbosen just don't buy anything with DSP

I have 2 of the 450 for His and 2 of the 800s for mids.

The 450 will never be pushed.
