Car Audio Amplifier ZE1000.1 2000W Monoblock Class D MOSFET Subwoofer Audio, 1-4 Ohm Stable, Low Pass Crossover, Mosfet Power Supply, Stereo

Which is the best way to wire 2 x 12 subwoofers svc as I don't seem to be getting much power to them with gain turned fairly high up

This amp powers my Alpine Type R @ 4ohm beautifully , very powerful and surprisingly even when running for an hour or 2 it was barely warm .. thinking about buying another spare one tbh or the bigger brother of this, very happy with my purchase!

Size was good and easy to install.

I would not recommend this product if you are expecting a 2000W output. It does not provide 2000W; I estimate the RMS power to be approximately 1000W. I plan to conduct wattage testing, and if my assumptions prove incorrect, I will revise or remove this review. Additionally, I have purchased a 6000W speaker to determine whether the issue lies with my unit. Update. I've noticed the amplifier playing crisps on very low level but once turned it up to about a third it's sounds distorted or clipping. I'm going to try one more thing a day double check all connections. If it doesn't go well I'll return it.

Fitted in a Jaguar Xf 2012, signal from factory rear speakers to line input of amp, driving Alpine Sub 12 in Bandpass Box, amp is being bridged for mono, not impressed had an Alpine 750watt before this, This amp is nowhere near half the power of the Alpine, I have to have the gain maxed, bass boost maxed, log is setup, subsonic filter off, and yes it does work, sounds like 100 Watt Amp. Most reviews and YouTube reviews say this is good, am I doing something wrong here. I'm 52, been a bass head since days of Tandy, I've had Alpines, Rockford's, phoenix Gold, even Sherwood, this Amp is just not that good. I'm going to change to a line to RCA and test again. If no improvement will return.
