Hi guys I want to buy new sub with amp. At the moment I found Alpine PMX-F640 amp with ALPINE 844BR sub + enclosure. Are they any good for £70? Any ideas how 8" sub will perform. I would be very thankful for help. Thanks Sam
 
Depends on your budget I guess? Back in't day I think I had an Alpine Type R 1200W 12" sub that cost about £100 powered by a Kenwood 1800W amp which cost about £200 second hand. Those were the days...
 
I used to have an all in one Sub im my corsa whe I first started driving that I then moved to my Yaris in later years.

It was one of these, it's only a small 6" all in one unit with 100w of power but it was more than enough. Lots of my friends at the time had massive 12" units with 500w amps but spent peanuts on a headunit and barely anything on speakers and they were just a bass heavy mess. I mixed that sub with some, admittedly entry level, but half decent speakers and it was a much nicer all round sound.

An 8" sub certainly wont make your windows shake with much force, but combine it with some decent speakers and you can get some nice sound.
 
I already have type g components in the front and they sound quite good for the price and compare to the stock ones. I can also get kenwood 12 KFC w3011 with jbl gt4000 amp for 60 pounds so the question is which one is going to be better?

Are you already amping your Type G's or are they just powered off the headunit? If it's the latter you will probably get better overall sound simply by feeding 50w each from a decent amp to those.
 
Those alpines type g 6.5 speakers run off a HU. Im not sure which one should i buy?

Both of subs that I found are 4 channel amps
Kenwood 12 KFC w3011 with jbl gt4000 amp for 60 pounds
or
Alpine PMX-F640 amp with ALPINE 844BR sub for 70 pounds

Any ideas? which one is better?
Also, JL subs are they any good I saw their prices and can get expensive BUT is it worth it?

I had a Denon DCA 3500 back in the day (90's I think? - £399 rings a bell) - it was a superb class A Amp and very expensive back then, keep looking for another on eBay but the only one listed is a DCA 3400 (£50) which wouldn't drive a SUB as well as front & rears which the 3500 would.

Still tempted to buy the 3400 but £50 for an amp that was fantastic in its day but a museum piece now?

Those Type G's are speakers that really benefit from high wattage if I remember correctly. If you look at there specs they are probably rated for 60w RMS where as your head unit is likely only giving them in the region of 10-15w depending on it's quality (ignore all the 4*50w rubbish on most headunits, that's the peak they can do and they simply cant sustain anything more than 15w or so).

Given that everything else you are commenting on is Alpine I'm going to go out on a limb and assume you have an alpine headunit. If so you could buy one of these https://www.alpine.co.uk/p/Products/SingleView/KTP-445 for just a little over £100 on the rainforest site or in the region of £70 on a popular auction site. I actually have one in my MX-5 as it's the simplest way of amping up power. You don't need to run any extra power wiring and it simply sits in between your iso wiring harness running of the same power as the headunit uses. It will push your type-g's up to getting a solid 45w RMS each which will make a huge difference compared to headunit only power. If you don't have enough bass and still want to buy one afterwards then at least you will have 90w of speaker power to better match a 300w sub instead of barely 30w of mid/treble and 300w of bass which in my opinion just sounds ridiculous.

I know the power pack isn't the cleanest system in the world as you are amping the already amped line level input and some people note that it can induce a slight hiss. However, I can't say I've ever noticed this in my car and I have it hooked into some half decent JL Audio component speakers.
