Budget / subtle mod, adding tweeters only

MooLard · 07-20-2016, 06:45 AM

Hi there

Have explored the option of buying OEM tweeters and the door surrounds with grilles and it's very expensive compared to buying a pair of universal tweeters. The issue however is that almost all tweeters are 4 ohm when the stereo and existing speakers are 2 ohm.
I realise it's not the preference and not ideal but what considerations do I need to make to wire these in, I guess it's the preference to wire in parallel also and then just not turn the volume up too high?
I read somewhere also that coding can be done to change the EQ, not really sure who I would ask to do that though.
The tweeters I was considering are Vibe Blackair entry level ones.
Thanks in advance,

Nope, base door speakers are 4 ohm, even says so on the sticker on the back of them (Promise, even went and checked).

The stockers even have the connector for the stock hifi tweeters (you'll need the pods for those unless you get creative/ugly with it).

You'll run tweeters in parralel, it's not like running subs in parallel (thus reducing impedance) because of the different frequency response.

Good morning!
Thanks for the direction, wow that was a lot of links to sift through, I had a good read and many of them are relating to premium upgrades, interesting reading but not what I am looking to do.
This link was the most relevant for myself - http://www.e90post.com/forums/showthread.php?t=352586
It re-confirmed that the tweeters should go in parallel and that this will be ok for the stereo, so I am going to do that. The tweeters I have chosen are silver and black, so sill be a bit obvious compared to OEM black grilles but it should be a nice addition.
For the price I might also do a pair in the rear door cards, fronts will be the greater benefit for myself and it's mostly solo driving when I'm using the car.

I did this mod and wow it really made a huge difference to the dull standard bass setup, (I did then lower the tweeter level which gave the whole sound a bit more depth after)

I just picked a second hand pair of bmw harmon kardon tweeters from ebay for about £60 including postage for the pair.
