i just got done installing my dls 6 x 9 just now. it is running straight off the hu and it sounds sick. i love it. took some time tweaking around with the fader and it has perfect balance now.
i was thinking though since my trunk is a huge space for the 6 x 9s, the mid bass doesn't sound as tight. even in the past when i had an amp hooked up to it, the mid bass just wasn't tight.
i was thinking about that chauncey but its just too much work. besides my rear window has limo tint so you can't see inside. you won't be able to see the boxes.
