[QUOTE="Wabatuckian, post: 8741811, member: 673204"] Hello, It's been a while since I was here. Started putting a SQ system in my Blazer, and then the Blazer got hit hard in the rear. Sooo, got a 2004 Grand Cherokee, which is the last year they used a solid front axle in that model. Recently I ended up with a Planet Audio subwoofer. I chose this because of the specs: 95dB 1w/1m and 500w RMS. I'm running a 400w RMS CV class D amp to replace my 300w RMS A/B that blew, so I figured this sub would be about perfect for the amp. Well, come to find out the amp is specified as 86dB in the manual. Not happy. Installed anyway. Not appreciably better than the old early-'90s Legacy I had in there. The only thing was that the Legacy was like 250w peak, and I would have blown it before long. Both were installed in the same cheap, pre-fab sealed box. I always wanted a punch at around 45Hz, so I dug out an old 2" port I had and took a hole saw to the box. [ATTACH]27907[/ATTACH] Sounded better. I'd like my low end back though. I'm thinking bandpass. I do have midwoofers. When I was a teenager, I had a CJ5. I'd turned the entire bed into a speaker box. Into this box went four Pyle Drivers (remember; 1990s.
