Add rear speakers, they make the most difference

What sub are you getting and where will it mount?

They are good for sure.

Interesting thing when you have M490 (door subwoofers and amp) is that the amp has inputs for rear speakers but no output connection. For this, just find a 6x40 amp from a 996 to replace your 4x40 and insert the pins of the rear speaker harness in the empty spots in the output connector and you're good to go. 996 amp is same physical size, fits existing bracket, and existing harnesses connect right up. A little modding of output connector is required but pins stay the same.

996 amps come in coupe and cabrio versions. First one I tried was coupe and I was underwhelmed. A cabrio version made a significant difference, so much so that it's as if it's the first time I've actually heard my door speakers sounding like subwoofers.

This is as far as I'm going for now, as the radio is inaudible at highway speeds and will see if next tire set improves that enough to consider more stereo power. Maybe some dynamat in doors.

You must have some really noisy tires

I can hear my stereo really well on the freeway and I just have a CDR-23, dash and rear speakers no amp, no sub

Agree, I can hear pretty good even at high speeds with top down. Stock radio, dash, door and rear speakers. No problems so far.

Hmm, those Infinity speakers are 2ohm...which means they should likely work with the OEM Bose system too...

Nice work.

I know this is a common issue, poor sound quality, but that's never been an issue in my Boxster. It not great but not bad enough that I ever cared. Works just fine up to about 80 mpg with the top down. I do have the door speakers so that helps. Maybe the PO upgraded the speaker. Glad to see upgrading is easy enough as Im sure at some point my speakers will crap out.

Or, it could be an age thing ... my age.

We'll see ... but other mods are more fun in the meantime so will just let them get more worn before replacing them.
