Front foot well speaker upgrade ?? Originals not that bad

Post by Brittas »

I have put a pioneer head unit in my 1.9 Z3 which has really improved the music sound. I have tried a 15cm pair of kenwoods that were £55 from Halfords ..... Sounded worse than standard speakers. I have tried some Fusion Encounter 240w . 6.5" 4 ohm. EM-CM65 ... these sounded worse.
It seems the original speakers are not that bad with an upgraded head unit.
I guess I will never get deep bass out of a 15cm speaker. I probably am going to stick with what I have unless anyone knows a speaker that will be a definite upgrade.

Did you run new wiring to the speakers?

The old speakers have their own amp.

Hi Gazza


I have a query in respect to your comment, is this an amplifier behind the left hand foot-well speaker or cross-over electronics for frequency split between the main and the tweeters?

Regards

I used existing wiring. Are you sure the bog standard set up has an amp?

Indeed, amp behind the LH footwell speaker.

I’m using an Alpine KTP 445 amp with my Alpine HU, it’s ok but as said you won’t get any real bass as they aren’t in sealed enclosures, I’m looking out for the sub enclosure and accompanying parts, then I will run my old 5 channel Genesis amp to power the lot!

Just found this!!! :(

Just replaced rear speakers, drivers side with new kick panel speaker and new door tweeter, then tweeter in passenger door. And took passenger kick panel off to find .... this!!!

How do bypass it???

I have a new head unit which is i think will be fine as amp too for now.

Does this thingy-amp power all speakers or just front?

I'm assuming it had inputs for 12v, gnd, left +/- in, right +/- in & right +/- (amplified out).. no left out as connected to speaker. is the right?

anyone cut this out and wired a bypass? help?!!!

Hi 882-user-1. I'm afraid that Gazza sadly passed away at the beginning of the year, so I'll answer on his behalf.

There is lots of info on here if you search for "footwell amplifier".

Here are some of the more interesting threads that I turned up:

viewtopic.php?f=10&t=39250&p=364849

viewtopic.php?f=10&t=9881

viewtopic.php?t=10889

There is a pinout in the first one, but the suggestion of running fresh wiring may be the cleanest solution, as you'll be able to use thicker wire to drive the speakers directly.

Cheers R.
