A lot of people talk highly of the Pioneer TS-D6902R 6x9's. Those are what I plan on using when I put my speaker lids on this winter. And they are rated 4-ohms too. Either those or the Biketronics 6x9's, but those are kinda pricey.

 

I haven't heard any others to compare but I added those pioneers recently the way GP has his installed and they sound awesome paired with the ss4.520.

 

I will be selling these speakers. NIB. I just heard back from Infinity, they said not to run those speakers with the 4 Ohm Amp. So, back to shopping for speakers....

 

Or you could replace the amp/amps. You could jump up to the Arc 4 channel to power all the speakers, or get a pbr300x2. Sell the other 2 amps to fund the Arc or sell the pbr300x4 to help with the 300x2.

 

I thought about that, I don't know why I like the idea of two amps. I have to admit that I love my loud music. And the Punch I was going to install will go in my side cover real nice. That way I don't have to do a lot of wiring to the inside of my bag.

 

I think the cheapest way out is to get new speakers.
