  1. I've had the Polk DB6502's in my wish list for a while now. After a couple glasses of wine, I saw they were on sale for $100 (I believe they come in pairs), so I ordered 2. My whip is a 2008 Chevy Trailblazer (short wheel-base version and non-bose). It has a 6.5" hole in each of the 4 doors and 2 in-dash mounts that I can stick tweeters in, so I just went with 6.5 components for this round. I've already installed a Pioneer AVH-X4800BS head unit and have an Alpine MRV-F300 amp on my Amazon wish list. I don't plan on adding a sub to the system because I value cargo room over subs. I'm sure this has been covered many times before, but what can I do to get "the best bass" out of my 6.5" door components? I don't know if I can be this picky without a designated sub, but I prefer smooth depth and SQ over brutal SPL. I don't need to rattle any license plates or anything, but as low as I can go without adding a sub is basically what I'm shooting for. Also, it may be worth mentioning that my wishlisted amp is rated for 50w rms/channel@4ohms where my speakers are rated at 100w rms/channel@4ohms. Just goofing around with home audio stuff, I would think 50w rms would easily max out the excursion on more or less any 6.5" that's not a dedicated sub. Is that correct in the car audio world or should I up my amp to match? Cheers!

    Thanks for the replies! Ultimately, I'm looking for "the best bass" I can get out of 6.5 components on a budget. Pretty much anything component will satisfy me in terms of clarity and response. Obviously, a proper sub setup would be ideal, but I'm not interested in sacrificing trunk space for subs at the moment. I'm looking for a solid ~60Hz a least (the lower, the better) setup from the doors, if possible on the cheap(ish). I am willing to spend a little bit more if a certain setup performs 'above and beyond' though. My reference point is a 1994 Mercury Villager (Nissan Quest). It didn't go super loud, and could barely thump your chest (simple 4-speaker setup without a sub), but it sounded nice and balanced with the ~5w speakers. Surely I can get similar quality plus ~10dB volume without spending more than the Villager was worth in the first place, right?

    How is the low end on them? Obviously, they're not gonna rattle things, but would I be consistently wishing I had a sub with these at casual listening levels? I'm not super locked-down at 100/pair, but I don't want to go much over that since I'm not building a crazy system. Just looking to replace the junk that's in there now.

    No opinions? Is there a way to figure out how much bass any given driver will put out? In home audio, you have T/S parameters that can give you a good idea with box modeling. I presume, cars would be more or less an infinite baffle setup and I'd really like to see which 6.5 gives me "the best bass" in terms of extension and clarity. That's totally subjective, but which one reduces the need for a sub the most would be another way to put it.

    I was casually browsing the interwebz and found that a populat budget component combo is the Polk Audio DB6502. These look intriguing since they allegedly hit 35Hz. I'm sure that's a bit of an exaggeration, or they were using different measurement techniques than I'll be using them in, but they still have "good bass" reviews. Curious if anyone's ran them before.
  6. I recently bought a Trailblazer (non-EXT version). The previous owner bought some el-cheapo Kenwood Road Series speakers in there and they're...well....awful. My EQ curve looks like a drunken rollercoaster just to make it sound half way decent. Even still, there's not much detail and they sound super muddy in the 100-200Hz range. Clearly, I'm interested in swapping them out with some nicer speakers, but I'm not very familiar with car audio components. I don't need anything crazy awesome (unless y'all feel obligated to donate to the cause ), but I do want to go "oh, that sounds nice!" when I switch it on after a long day at work and not have any offensive frequencies or find it noticeably lacking in any particular department. The Trailblazer setup and speaker holes are as follows: Pioneer AVH-X4800BS head unit (14w RMS) I have yet to get an amp, but I see good reviews on the JBL GX-A604. I'd probably slide it under my passenger seat. A 6.5" in each of the 4 doors. A separate tweeter mount in the front doors only (right next to the drivers at the bottom). I'll relocate the tweeters to be on the.....whatever that trim piece is at the top-front of the door panel that hides the mirror screws or in the dash speaker holes. 2x 2.5" speaker holes in the dash. These were used with the optional Bose system, but mine doesn't have that, so I just have empty brackets up there. My goals: Under $100/pair. Preferably a line with both a component option and a coaxial option. I'd run components up front and coaxials in the rear doors where there isn't really a good place to plop a separate tweeter. Good SQ throughout the range. I bought 2 sets of JBL Club 6" x 8" for my pickup and was not impressed. They're harsh and honky without some beastly EQ and have no lows. As good a bass as I can reasonably get from 4x 6.5"s. I won't be running a sub, but I don't need to rattle my license plate either - though it would be nice to crank it up a little bit every now and then. I just want nice, strong, smooth, detailed response down to at least 40Hz (with cabin gain) or as close to that as I can get at casual listening levels. As stealth as I can reasonably get. I don't want to put anything in the trunk nor do I want to get custom panels. I want it to look stock with the possible exception of the mounted tweeters. The JBL GTO609C and matching coaxials look like a decent set. I see a handful of reviews say they have good bass response, but I'd like to get some thoughts from the audio heads before diving in.
  7. I just purchased a new-to-me 2008 Chevy Trailblazer. It's the short wheel base version and does not have the Bose option. When I purchased it, the previous owner had already installed some Kenwood 6.5" speakers in all 4 doors. After I purchased it, I found that the stock radio head unit was shot and acting up, so I purchased a Pioneer AVH-X4800BS to replace it. I discovered that the PO didn't even wire up the speakers correctly in terms of polarity, so I straightened the polarity out while I was at it. In short, there seems to be a huge hump in response at 100-200Hz, but anything below 100Hz just falls off a cliff. I've EQ-ed the hump down, so things sound pretty smooth now, but I just can't get any notable bass out of it without distortion setting in. I have the lows boosted ~6dB on the head unit, but it still sounds light on the low end and I can't turn it up past ~80dB without distortion. I've taken my flashlight and checked the cone movement and I don't believe it to be anywhere near xmax. It only looks to be moving about 0.5mm. I guess my question is: what the dilly??? The speakers are rated to 40Hz (not sure if I believe that though) and have a sensitivity of 90dB. If all the specs are correct, my 14 watt rms per channel head unit should give me much more thump than I'm getting once you take into account 4 drivers and cabin gain. Obviously, I'm not building a thump-thump machine, but I'm not joking when I say my '94 minivan had more bass presence and clarity with 4x 7-watt stock drivers. My F-250 with a JVC KD-R970BTS with JBL GX862's absolutely beats the snot out of this setup! Any thoughts on 1) why my bass falls off a cliff after 100Hz and 2) why distortion begins way sooner than it seemingly should?
