For those that don't want to read everything and want a quick-and-dirty question, jump to the bottom. For everyone else:
I have a 2001 Mustang GT Convertible fitted with the MMC6500 up front and MMC5250 in the rear, powered by a Polk C400.4. The headunit is an Alpine CDA-9857. I also have a JL Audio Stealthbox (before they discontinued them for this car). It had originally come with a (blown, I bought used) JL 10W6AE (Anniversary Edition) which was specially made for that enclosure. I then replaced it with a JL Audio 10W3V3-D4 which handles 300W @ 4Ohms. I did this as it just barely fit (depth-wise) and seems to have almost the exact same volume requirements as the 10W6AE.
Unfortunately, I'm running a Sony XM-2100GTX for my subwoofer. It is a 2-channel amp, rated at 250W RMS @ 4Ohms (bridged, obviously).
I can barely hear the subwoofer. It sounds terrible, and actually I think the amp is dying, or just can't handle the 10W3V3. The amp is just a leftover I had from when I was younger. The rest of the system sounds incredible, though!
I'm looking for an amplifier to power my 10W3V3. I have been contemplating the C500.1 as it produces 350W RMS @ 4Ohms. I'm worried, though, of overpowering the speaker. I know all of Polk's amplifiers are underrated, and I can vouch for that as my C400.4 (which is rated 75Wx4 @ 4Ohms) was measured at 93Wx4 RMS.
Would this be a good match for the 10W3V3? I'm debating between this and a JL Audio 250/1 (which would be underpowering the subwoofer a bit, which I would rather not do considering the money I have spent on the rest of the system and the kind of quality I want).
I would rather stay with Polk as I love the quality and the value of them, and the rest of my system is Polk. It would also look really nice in my trunk:
What is your take on this?
QUICK AND DIRTY QUESTION: What would be a better amp for a JL Audio 10W3V3-D4; a JL 250/1 or a Polk C500.1?
