My son (16 year old & 6'-4") has a 1998 TRD Tacoma xTended cab v6 with a stock alternator. About 20 years ago, I worked as an installer and salesperson at a stereo store (until I decided it had to be away to make an easier living).
So before I gave him the Tacoma, I installed the following system for him: Pioneer Double Din DVD 3200BT, Alpine PDX-5 Class D amp (75w x 4 + 300w sub channel), 3 Pairs of MB Quart component 4 ohm speakers (front doors, rear panels & Q Form Kick Panels) and a JL Audio Stealthbox (sealed with one 4 ohm 10" JL sub).
I also installed everything else on my profile (he paid nothing, we owe nothing on this truck and I fixed everything wrong with this truck). When he turned 16, I gave him the truck with the understanding that I am doing nothing else on this truck because I have to start saving for my other son's (15) car.
Needless to say, he wants more bump (but, he is happy with the mids and highs). He took out the Stealthbox and installed my old MTX Thunderform box (out of my old 2001 Dodge truck) sealed with two 10" MTX 4500 subs (total sub load 4 ohms). The two 10's do bump more but, now he is wanting to put them in a ported box.
The ported box will take up most of his back seat (so I don't like this idea). I am trying to get him a custom ported box that will only take up one back seat and will not come up past the window line. Do you think a ported box that size will be louder?
Also he wants my old Orion 800.4 Class A/B amp (100w x 4) just for the subs, I told him that his alternator would not be able to provide enough current for the Orion and Alpine amps. Needless to say, he does not believe this and just wants to hook this up.
I tried to explain to him the difference between 8 ohm (each MTX is 8 ohm) and 4 ohm sub (JL Audio).
In return he wants to sale the MTX Thunderform box (unloaded) and the JL Audio Stealthbox (loaded).
So tell me what you think about the ported box and/or adding the extra amplifier? Or if you have another suggestion, please let me know. I just don't want to see him waste his money.
Btw, he reads this website too, so please no flaming.
