Team-BHP - Amp 2/3 channel, for OEM HU

- - Amp 2/3 channel, for OEM HU (https://www.team-bhp.com/forum/car-entertainment/83751-amp-2-3-channel-oem-hu.html)

since i've already installed components on rear doors, i was wondering if i could get a 2 channel amp to power them, since they are currently underutilized.
so can anyone give me suggestions for cheapest amp with speaker level inputs which are 2 channel.
suggestions for 3/4 channel amp are also welcome because i may plan to add a sub later.
remember i want cheapest solutions (low end amps), i am willing to buy in grey.

My Rear doors have JBL GTO608c, front doors are OEM, 2 tweeters on A pillars are also OEM. Car is Fabia.
thanks.

a good 2 ch. amp will cost you 4-5K and a simialr 4ch. will cost you 6-7K so a 4ch. makes a lot of sense. Kenwood, Pioneer, JBL, etc make amps that are excellent VFM.

what about fake amps, like branded fakes, cheap chinese ones, how good are they.
i may just want to power comp's for now with a amp.

one more thing if i do add an amp what about the remote wire, i believe the Stock HU will not have an output for same, so is there a workaround for it?

you really don't need an amp for the comps at the moment. buy a cheap 2 ch amp ( I'd say get a kenwood - they come with speaker level inputs. insist on getting the wiring harness for the speaker level input as well) , swap the front and rears, and run the fronts off the amp.

for stage 2, you can get a HU with more drive (like an alpine) and a sub

thank you for your highly valued opinion, that was almost what i had in mind except that in stage 2, i would not change the hu but add only a more powerful amp and a sub

i've been living with an alpine HU and a 2 channel amp for the sub alone. Once you've high passed the speakers, and let the sub handle all the bass, you will not feel the need to amp the main channels, since bass is what needs the most power, and its being handled by the sub already
