Hello Callum, The product you have posted the question on is just the speaker itself and not an amplifier kit, we do sell a kit that uses this speaker https://www.kitronik.co.uk/2158-3w-class-d-stereo-amplifier.html, this contains all the parts for the amplifier including two speakers.Posted byon Thursday, 26 January 2017
Yes this speaker will work fine with the MP3 Mono amp kit.Posted byon Thursday, 13 October 2016
These are the speakers that are supplied with the 3W class D amp kit, so yes they are fine to use with it.Posted byon Thursday, 21 January 2016
The amplifier chip used in the high powered amp kit is not specified to drive a 4 Ohm load, as such you may have issues with using these speakers. We would suggest using an 8 Ohm speaker as this is what the amplifier chip is designed to drive.Posted byon Wednesday, 16 December 2015
It depends on the amplifier in your car.What matters is that the amplifier can support the impedence of the speakers (4 Ohm). If it can't it may damage the amplifier or speaker.Posted byon Monday, 22 June 2015

0voteA: It would very likely damage the speakers, is the amplifier 10W at 8 Ohm or 4 Ohm? We do however sell 20W 8 Ohm rated speakers that would work well.Posted byon Tuesday, 28 October 2014
0voteA: Hi Rob, They are compatible and it does improve the quality of sound noticeably!Posted byon Tuesday, 27 May 2014
0voteA: The speaker has solder terminal connections, but no cable, reels of cable are available separately, see www.kitronik.co.uk/products/wire-leads-and-connectors/wire/figure-8-speaker-cable-2x-7x018mm/Posted byon Tuesday, 22 April 2014
